If the diagnosis is not made immediately after delivery, but for various reasons only identified within the next few days, a delayed primary repair can be performed. However, when a repair of the anal sphincter is performed to treat fecal incontinence (usually months or years after childbirth), it is regarded as a secondary sphincter repair even though a direct primary repair may or may not have been attempted following delivery. In the United Kingdom, primary anal sphincter repair is conducted by obstetricians while secondary sphincter repairs are predominantly performed by colorectal surgeons. In order to standardize the description of anal sphincter injury, Sultan [6] modified the existing classification of perineal tears, and the new classification has been accepted by the Royal College of Obstetricians and Gynaecologists [7], The British National Institute for Health and Clinical Excellence [8], and the International Consultation on Incontinence [9]. This classification is divided into four degrees outlined as follows: First degree: Laceration of the vaginal or perineal skin only. Second degree: Involvement of the vaginal/perineal skin, perineal muscles, and fascia but not the anal sphincter. Third degree: Disruption of the vaginal/perineal skin, perineal body, and anal sphincter muscles. Isolated tears of the rectal mucosa without involvement of the anal sphincter (Figure 93. It has been reported in 16% of instrumental deliveries [13] and 11% [14] (19% in primiparae [15]) in centers where midline episiotomy is practiced. Midline episiotomies have been favored in North American practice while mediolateral episiotomies are favored in Europe. The prevalence of anal incontinence (including flatus as a sole symptom) and fecal incontinence (liquids and solids with or without flatus) following end-to-end repair ranges between 15% and 61% (n = 35; mean = 39%) and 2% and 29% (n = 25; mean = 14%), respectively (Table 93. Despite repair, persistent sonographic anal sphincter defects were identified in 34% [23] to 91% [46] of women. Anal resting and squeeze pressures are consistently lower in women who have previously sustained anal sphincter rupture [10,11,30,32,38,41,44], and the anal canal is shorter after repair [10,22]. However, these measurements were still within the normal range and no relationship was demonstrated between abnormal latency and incontinence. Although anal sphincter disruption and repair is invariably associated with some degree of denervation and atrophy, current available neurophysiological tests are neither sensitive nor specific enough to quantify pudendal neuropathy. There is, however, evidence to show that poor outcome following primary [10,25,30] and secondary [4] repair may be related more to persistent mechanical disruption as demonstrated by anal endosonography rather than pudendal neuropathy. Unsatisfactory outcome following primary sphincter repair may be attributed either to operator inexperience or repair techniques and subsequent management. Training and experience of clinicians performing perineal repair have been questioned [49,50] and hands-on training workshops have been shown to influence a change in clinical practice [51]. Fulsher and Fearl [54] also described this technique but emphasized that no sutures should pass through the sphincter muscle. More specifically, Cunningham and Pilkington [55] inserted four interrupted sutures in the capsule of the external sphincter at the inferior, posterior, and superior points. In 1948, Kaltreider and Dixon [56] described the end-to-end repair technique that was used since 1935 in which one mattress or figure-of- eight suture was inserted to approximate the sphincter ends. Obstetricians have used the end-to-end repair technique for decades either by single-interrupted sutures, “figure-of-eight” sutures, or mattress sutures [10] (Figure 93. Persistent anal sphincter defects following repair has been reported in 34% [23] to 91% [46] of women (Figure 93. By contrast, when fecal incontinence is due to sphincter disruption, colorectal surgeons favor the “overlap technique” for secondary sphincter repair as described by Parks and McPartlin [57]. Jorge and Wexner [58] reviewed the literature and reported on 21 studies using the overlap repair with good results ranging from 74% to 100%. It is now known that similar to other incontinence procedures, outcome can deteriorate with time and the follow-up study at 5-year follow-up reported 50% continence [59]. However, a number of women in this study had more than one attempt at sphincter repair [59]. They observed that compared to matched historical controls [10,61] who had an end-to-end repair, anal incontinence could be reduced from 41% to 8% using the overlap technique and separate repair of the internal sphincter. Based on this, they recommended a randomized trial between end-to-end and overlap repair. However, a true overlap [10,57] is not possible if the sphincter ends are not completely torn, and attempts at overlapping would only place tension on the repair. Of the 23 women in the end-to-end 1422 group and 18 in the overlap group, only 15 and 11 women, respectively, returned for follow-up at 3 months. No significant difference was found between the groups in terms of symptoms of fecal incontinence or transperineal ultrasound findings. However, the authors acknowledged that the major limitations of their study were that randomization was inaccurate and that their study was underpowered. This trial was specifically designed to test the hypothesis regarding suture-related morbidity. At 6 weeks, there were no differences in terms of the need for suture removal due to pain, suture migration, or dyspareunia. The authors claim that there were no differences in outcome based on repair technique. At 12 months, they had an 81% follow-up rate and found that 24% in the end-to-end and none in the overlap group reported fecal incontinence (p = 0. There were no significant differences in dyspareunia and quality of life between the groups. After 12 months, 16% of women in the end-to-end group and no subjects in the overlap group reported deterioration of defecatory symptoms (p = 0. Rygh and Korner [64] performed another randomized controlled trial (n = 101) with the primary outcome measure “of at least weekly solid stool incontinence. However, there were more women with symptoms of anal incontinence in the end-to-end repair group (34% vs. They reported significantly higher rates of flatal but not fecal incontinence in the overlap group. At a 3-year follow-up however, there was no significant difference in anal incontinence between the groups, but the rate of fecal incontinence in the end-to-end group doubled while it remained static in the overlap group [67]. This highlights the importance of longer term follow-up as one technique may prove to be more robust. At 36 months (based on only two small trials), there appeared to be no difference in flatus or fecal incontinence between the two techniques. At a median follow-up of 2 years, 23% complained of anal incontinence, 23% developed wound infection, 27% complained of dyspareunia, and one developed a rectovaginal fistula. However, a delay in repair may be justified in exceptional circumstances when an experienced obstetrician may not be 1423 available. Ideally, the repair should be conducted in the operating theater where there is access to good lighting, appropriate equipment, and aseptic conditions. In our unit, we have a specially prepared instrument tray containing a Weitlander self-retaining retractor, four Allis tissue forceps, McIndoe/Metzenbaum scissors, tooth forceps, two artery/mosquito forceps, stitch scissors, and a needle holder (www. Muscle relaxation is necessary to retrieve the ends especially if the intention is to overlap the muscles without tension. The full extent of the injury should be evaluated by a careful vaginal and rectal examination in lithotomy and graded according to the classification earlier (Figure 93. If there is any uncertainty about the grading of Grade 3a or 3b, it should always be given the higher grade. To minimize the risk of a persistent rectovaginal fistula, a second layer of tissue should be interposed between the rectum and vagina by approximating the rectovaginal fascia. In the presence of a fourth-degree tear, the torn anorectal epithelium is repaired with a continuous nonlocking fine suture such as Vicryl 3-0. The technique of interrupted sutures with the knots tied in the anal lumen is recommended when catgut is used as catgut undergoes phagocytosis in tissues and increases the risk of infection. A subcuticular repair of the anal epithelium via the transvaginal approach has also been described [5] although there is some concern that the thin anorectal mucosa could tear with the passage of stool. Compared to a braided suture, these monofilamentous sutures are believed to be less likely to precipitate infection. Nonabsorbable monofilament sutures such as nylon or Prolene (polypropylene) can cause stitch abscesses, and the sharp ends of the suture can cause discomfort, necessitating removal. Alternatively, one randomized study has suggested that Vicryl 2-0 can also be used although the primary outcome was not the success of the repair but suture migration [62]. In women with major tears, defecatory symptoms were more prevalent and associated quality of life was worse. In order to perform an overlapping repair, the muscle may need mobilization by dissection with a pair of McIndoe or Metzenbaum scissors, separating it from the ischioanal fat laterally. Overlapping allows for a greater surface area of contact between muscles (Figure 93. Consequently, the woman may maintain continence in the short term but would be at risk of developing incontinence later in life. It has also been shown that a shorter anal length is the best predictor of fecal incontinence following secondary sphincter repair [74]. Unlike end- to-end repair, if further retraction of the overlapped muscle ends were to occur, it is highly probable that muscle continuity would be maintained. Hemostatic “figure-of-eight” sutures should not be used to repair the sphincters (or anorectal mucosa) as it could cause ischemia. A short deficient perineum would make the anal sphincter more vulnerable to trauma during a subsequent vaginal delivery. The vaginal skin is sutured and the perineal skin is approximated with a Vicryl 3-0 subcuticular suture. A rectovaginal examination should be performed to confirm complete repair and ensure that all packs or swabs have been removed. Severe perineal discomfort, particularly following instrumental delivery, is a known cause of urinary retention, and following regional anesthesia, it can take up to 12 hours before bladder sensation returns. A Foley catheter should be inserted for 12–24 hours unless the midwifery staff can ensure that spontaneous voiding occurs at least every 3 hours. A pictorial representation of the tears proves very useful when notes are being reviewed following complications, audit, or litigation [16]. As passage of a large bolus of hard stool may disrupt the repair, a stool softener (lactulose 15 mL bd) is prescribed up to 10 days postoperatively. A randomized trial (n = 105) of constipating versus laxative regimens found that the use of laxatives was associated with a significantly earlier and less painful first bowel motion as well as earlier discharge from hospital [76]. Compared to 5% in the laxative regimen group, 19% in the constipated regimen group experienced troublesome constipation (two required hospital admission for fecal impaction). There were no significant differences in continence scores, anal manometry, or endoanal scan findings. Bulking agents such as ispaghula husk (Fybogel) should be avoided as another randomized study [77] has indicated that incontinence occurred significantly more often (33% versus 18%) when lactulose and Fybogel were consumed compared to lactulose only. All women should be given advice on pelvic floor exercises while others with weak or absent sphincter contractility may need electrical stimulation [78]. It is known that the risk of recurrence of anal sphincter injury in centers that practice mediolateral episiotomy is 4. In a survey conducted in 2010 [83], 30% of hospitals in the United Kingdom had such a dedicated clinic. A proper vaginal and rectal examination should be performed to check for complete healing, scar tenderness, and sphincter tone. Mild incontinence (fecal urgency, flatus incontinence, infrequent soiling) may be controlled with dietary advice, constipating agents such as loperamide, physiotherapy, and/or biofeedback. Women who have severe incontinence should, in addition, be assessed by a colorectal surgeon for a secondary sphincter repair or sacral nerve modulation. Women who have had a successful secondary sphincter repair for fecal incontinence should be delivered by cesarean section [84].


cheap erectafil 20 mg amex

As a result erectile dysfunction pills in pakistan erectafil 20 mg purchase without a prescription, a catheter was placed 3 cm in a posterior cardiac vein impotence spell erectafil 20 mg purchase visa, at which point the mitral annulus was approximated erectile dysfunction medication injection buy erectafil 20 mg mastercard. At this site the earliest atrial activation was recorded impotence juice recipe erectafil 20 mg buy without prescription, 35 msec prior to that in the coronary sinus erectile dysfunction treatment in bangkok generic 20 mg erectafil amex. This is the same patient as recorded in Figure 13-16 in whom earliest activation was recorded in a cardiac vein. Ablation in that cardiac vein during ventricular pacing resulted in block in the bypass tract in less than 3 seconds (see arrow). The earliest activation time locally was nearly 75 msec in pole 5, which had a small R-deep S wave. This suggested that the coronary sinus was removed from the mitral annulus and earliest site. A catheter (mapd) inserted in the vein proximate to pole 3 revealed the earliest bipolar and unipolar recording some 30 msec at the head of the earliest bipolar recording (in the coronary sinus). If at all possible, ablation should be carried out in sinus rhythm or preferably during atrial or ventricular pacing. Block in a bypass tract results in immediate termination of the tachycardia, which is often associated with displacement of the catheter from its critical position. One can only hope for return of conduction over the bypass tract in a short period of time so that it can again be targeted. Unfortunately, on some occasions the bypass tract conduction will not return until the patient leaves the hospital and the tachycardia recurs. Use of mapping system may obviate this problem by tagging the initial site of ablation, allowing the investigator to return with great precision to that site. Selection of a good site during ventricular pacing may sometimes be difficult because of diminution of the amplitude of the atrial electrogram and merging of the atrial electrogram with the ventricular electrogram because of the influence of slanted bypass tracts. Rapid ventricular pacing to produce V-A block can demonstrate what component of the ablation electrogram is ventricular and what is atrial (Fig. Another maneuver is to alternatively pace the atrium and ventricle and the ventricle separately (Fig. In this way, V-A conduction over the bypass tract will only be evident with ventricular pacing only; electrograms present only during ventricular pacing represent atrial activity. As mentioned above, as well as in Chapter 10, bypass tracts are frequently slanted (see Figs. The local V-A time measured on the ablation catheter must remain constant if activation occurs over the bypass tract, regardless of which direction the ventricular wavefront engaging a bypass tract is traveling. Sites that may have a shorter V-A interval in response to retrograde conduction over bypass tract activation during a ventricular activation from one direction may have a markedly different V- A P. The first two pace complexes are a search of the atrial deflections, the beginning of which are hard to see in the distal coronary sinus and the ablation catheter. This third ventricular paced complex is not associated with atrial electrograms and allows one to see where the atrial electrogram began. V-A block during rapid pacing is therefore a good method to assess the exact location of atrial activity during circus movement tachycardia or ventricular pacing. Simultaneous pacing captures the local atrial electrogram; its absence helps to determine the onset of the atrial activation during ventricular pacing (arrows). The effect of a paced wavefront from right to left (A) and left to right (B) on local V-A times is shown. The ventricular site of insertion should have a constant (V-A) interval regardless of the direction of activation. Using the ventricular approach the catheter is positioned just underneath the mitral annulus as depicted in Figures 13-18 and 13-19, to record a ventricular electrogram and an atrial electrogram. At the appropriate position (near the ventricular insertion site) the atrial deflection is usually one-fourth the size of the ventricular deflection and during ventricular pacing the atrial deflection gets even smaller and sometimes becomes lost in the ventricular electrogram. The maneuvers discussed above can help define the onset of atrial activation during conduction over the bypass tract. During ventricular pacing, retrograde atrial activation is usually earlier than that recorded in the coronary sinus. In rare cases, a left lateral bypass tract with a long A-V conduction time (which may or may not be decremental) is present. In such cases, no overt pre-excitation is obvious in sinus rhythm, but may only be manifest by pacing at the left atrium or via the coronary sinus. When using the ventricular approach, because the contact is usually good, we aim for a temperature of 55° to 65°C with temperature control catheters, or the lowest power, which results in a 10-Ω drop in lead impedance. If one is at the appropriate site, loss of conduction over the bypass tract is accomplished in less than 10 seconds (Figs. If the transseptal approach is used, catheter stability is not as reliable, and a sheath is invariably required to maintain stable contact. The sheath is usually positioned in the lateral left atrium through which the catheter is passed toward the medial aspect of the mitral annulus. The catheter can then be withdrawn slowly to map the mitral annulus until the earliest retrograde atrial activation is recorded during the tachycardia or ventricular pacing. Achievement of appropriate temperatures, or, more importantly, drops in impedance are more difficult from the transseptal approach due to the loss of temperature via convective cooling of the blood. Finally, if the ablation is carried out within the coronary sinus, and a standard 4- to 5-mm tip catheter is used, I recommend keeping temperatures ≤55°C, and use impedance drops to determine how much energy is delivered. I generally use the lowest energy, which results in a 10-Ω drop in impedance, regardless of the temperature. Use of a cool-tip catheter decreases the risk of char and, as stated above, temperature cannot be used and a decrease in impedance demonstrates effective energy delivery. Usually, epicardial pathways are eliminated quickly, but I try to maintain delivery of energy for a minute since I believe many of these bypass tracts insert as multiple twigs or broad bands in the muscular sheath of the coronary vein. The vast majority of bypass tracts around the tricuspid valve can be reached through catheters introduced via the inferior vena cava, although occasionally the catheter must be placed via the superior vena cava when the bypass tract is located inferolaterally (i. As stated earlier in the chapter, although some investigators have suggested using a small catheter placed in the right coronary artery to guide mapping of right-sided bypass tracts, we believe this should not be done routinely and that regionalization of the bypass tract can be readily accomplished using a Halo catheter or a multipolar catheter positioned around the tricuspid annulus. When pre-excitation is present, the earliest onset of ventricular activation recorded on the ablation catheter should precede the delta wave by at least 25 msec using either unipolar or bipolar electrograms. Examples of mapping and ablation of a right anterior manifest, anterogradely conducting and a concealed right lateral bypass tract P. Sheaths are available and helpful for the stabilization of catheters positioned inferolaterally along the tricuspid annulus. Folding over of the atrial myocardium around the annulus is associated with bypass tracts that may insert into the atrium 1 cm from the annulus. Posteroseptal bypass tracts, which are actually the second most common, usually can be readily approached in the inferior septal regions of the tricuspid annulus. This name is actually a misnomer, since they are not truly “septal,” but inferoposterior to the true atrial septum, which ends in the His–A-V node area, at the central fibrous trigone. These are truly septal and may be approached from either the right side or on rare occasions from the left side and are associated with a 5% incidence of heart block if the catheter is positioned in the triangle of Koch. Such bypass tracts should be ablated with the catheter on the tricuspid annulus or on the ventricular side of the tricuspid annulus to decrease the incidence of A-V block. Safety will further be enhanced by using the lowest power required to get an impedance drop of 10 Ω. They often exhibit a bypass tract potential and/or early activation at a site without a His bundle deflection (Fig. The para-Hisian pathways, by definition, are recorded with simultaneous His bundle activity from which it needs to be distinguished. In this particular instance the ablation catheter was positioned so that the tip produced pressure perpendicularly to the His bundle region. This led to a rather slowly inscribed ventricular depolarization consistent with the onset of ventricular activity as well as a slowly inscribed “inferior” His bundle deflection, which times identically with the discrete bipolar deflection on the His bundle catheter. With the loss of pre-excitation there is loss of the negative deflection between the A and the broad H and disappearance of the delta wave. These fibers are very superficial and protected by a fibrous sheath, so with use of low power and temperatures not exceeding 52°C the risk of permanent heart block is less than 1%. Rapid ventricular pacing is often necessary to discern the onset of atrial activity (Fig. A left lateral bypass tract is present with a long conduction time, which was associated with a local A-V interval of 90 msec. No overt pre-excitation is present because the area of the ventricle that is “pre-excited” occurs after the onset of normal activation. A and B: Ventricular pre-excitation is recorded from a unipolar rove electrode as an intrinsicoid deflection 25 msec before the delta wave during sinus rhythm. Anteroseptal bypass tracts are characterized by the presence of a bypass tract potential and the absence of a His bundle potential in the apex of the triangle of Koch. The most difficult for me have been the right free wall pathways, particularly if approached from the inferior vena cava. This is due to both poor contact and the fact that these bypass tracts are often off the annulus, crossing through a “folded” right atrium over the ventricle. Initial attempts at ablation from the right side produced transient success but the arrhythmia recurred 6 hours later. On the following day a second ablation was successful using the retrograde aortic approach. The third was right free wall pathway that disappeared in 10 seconds after the onset of ablation, only to recover 2 weeks later; repeat ablation resulted in subsequent durable success. The fourth was in right-sided accessory pathway in a patient with Ebstein anomaly. Bypass tract conduction blocked in less than 10 seconds with ablation, but recurred within 2 weeks; a recurrent ablation attempt resulted in the same sequence of events. This tracing compares the electrograms recorded in the His bundle recording and the ablation catheter before (left) and after (right) catheter pressure caused temporary bypass tract block. This is validated with loss of pre-excitation demonstrating consistent positioning of the His bundle potential associated with the slowly inscribed second potential in the first complex and loss of the pre-excitation in the first negative potential in the first complex. Right bundle branch block is present, which facilitates the observation of a broad slowly inscribed His deflection from the ventricular myocardium. In general, the greater the experience of the operator, the higher the success rate and the fewer lesions used. While success rates in many laboratories exceed 95%, the use of multisite “insurance lesions” to achieve these results should be discouraged. The use of two or less sites should be a goal and requires attention to careful mapping to achieve. We have had only two recurrences, both in two patients in whom we failed initially. The other gentleman is currently being treated for active hepatic pulmonary and renal tuberculosis and his tachycardias are readily controlled by antiarrhythmic drugs at this time. Ablation of Pre-excitation Variants The two major variants of pre-excitation that lend themselves to catheter ablation are slowly conducting concealed bypass tracts and atriofascicular bypass tracts. The recognition, diagnosis, and characteristics of both these variants are detailed in Chapter 10. The permanent form of reciprocating tachycardia is generally caused by a slowly conducting bypass tract, which is commonly in the right inferior paraseptal location. In my experience, in almost half (45%) of the patients in whom we have diagnosed a slowly conducting bypass tract, the bypass tract was located in the left inferior or left posterior (free wall, greater than 4 cm inside the coronary sinus). The remaining half were located between the base of the pyramidal space, which is formed by the points of contact of the pericardial reflection with the posterior right and left atrium (right and left inferior paraseptal). An example of a slowly conducting bypass tract inserting 4 cm inside the coronary sinus is shown in Figure 13-38. In most series the majority of these slowly conducting bypass tracts occur around the region of the os of P. The atrial insertion sites of these slowly conducting bypass tracts usually demonstrate multicomponent electrograms. Successful ablation of these bypass tracts exceeds 90% but often requires lesions delivered in the coronary sinus. In (A), circus movement tachycardia in a slowly conducting bypass tract is present. Atrial activation is color coded in the electroanatomical map during circus movement tachycardia. The His bundle is marked by the orange circle and the ablation sites adjacent to it are shown. The earliest atrial activation is shown in dark red with subsequent activation in lighter red, orange, yellow, green, etc. Atriofascicular bypass tracts are the other variant of pre-excitation in which ablative techniques have been useful. Although it was originally thought that these pathways were nodofascicular, it is clear that the vast majority of these pathways originate in the anterolateral right atrial tricuspid annulus and act as a secondary conducting system inserting into the distal right bundle branch. While insertion into the myocardium adjacent to the right bundle branch is possible in some cases, the presence of a retrograde V-H interval of less than 25 msec suggests a direct insertion into the right bundle branch itself. Direct recordings of this pathway at the anterolateral tricuspid annulus look like a typical A-V junctional recording with an atrial deflection, a sharp spike, and a ventricular deflection. The sharp spike is believed to represent the “Mahaim” fiber, and may indeed represent an equivalent to a His potential in an auxiliary conduction system. Details of the mapping techniques used to prove the presence of an atriofascicular bypass tract were given in Chapter 10. The approach to this bypass tract is via the inferior vena cava and may or may not require a sheath for catheter stability. Most of these bypass tracts can be located along the lateral tricuspid annulus from which the atrial and “Mahaim” potential can be recorded.

order erectafil american express

If the sling has significant tension on it erectile dysfunction treatment youtube erectafil 20 mg buy low cost, it may be especially difficult to identify erectile dysfunction massage order erectafil discount. Insertion of a cystoscope or sound into the urethra with gentle upward torque improves visualization of the bladder neck and places tension on the sling erectile dysfunction ka ilaj order genuine erectafil on line, allowing for its identification impotence cream erectafil 20 mg lowest price. Once the sling is isolated erectile dysfunction doctors in brooklyn purchase cheap erectafil line, it should be separated from the underlying periurethral fascia with sharp or blunt dissection. The dissection may be facilitated by grasping the sling with an Allis clamp on either side of the midline and exerting downward pressure. Care should be taken to avoid injury to the bladder and urethra by beginning the dissection distally, identifying normal urethra then proceeding more proximally until the plane between the sling and urethra is identified. A right-angle clamp can be placed between the urethra and periurethral fascia and the sling. Alternatively, if scarring is dense and the plane between the sling and periurethral fascia cannot be developed easily, the sling can be isolated lateral to the midline, off of the urethra. For practitioners who do not routinely perform this procedure, this lateral approach followed by lateral incision provides a margin of safety in minimizing inadvertent urethral injury. The edges of the sling are then mobilized off the periurethral fascia to , but not through, the endopelvic fascia (Figure 79. Lateral support is preserved because the retropubic space is not entered, and the urethra is not freed from the undersurface of the pubic bone. Typically, synthetic material is excised and autografts/allografts are left in place. In cases of autologous or biological materials, if the sling cannot be clearly identified, then formal transvaginal urethrolysis (see in the following text) should be performed. Unlike autologous and biological slings, it is imperative to identify the sling and cut it. Conversion to urethrolysis without specifically cutting the sling may fail to relieve obstruction. Usually, the sling is easily found, and identification can be aided by palpation of the sling. However, sometimes this can be quite difficult, especially in cases where the sling has migrated proximally or has rolled onto itself and created a tight narrow band. The cut ends can be grasped with clamps and dissection proceeds hugging the sling to minimize injury to underlying tissue. If sling incision is not successful in relieving obstruction, formal urethrolysis may be carried out. A right-angle clamp may be placed between the sling and the periurethral fascia to avoid injury to the urethra. The approach chosen depends on several factors that include patient presentation, type of initial anti-incontinence surgery, history of prior urethrolysis, and surgeon and patient preference. In general, proceeding from the less morbid transvaginal approach and reserving the retropubic approach for failures is prudent. However, exceptions exist that would favor a retropubic approach as the primary initial procedure such as inadequate vaginal access precluding a transvaginal approach, in cases where the original anti-incontinence surgery was performed transabdominally or associated with bladder perforation, fistula, or other operative complication, after a Burch resuspension, or associated with intravesical mesh exposure, which must be removed. This was felt secondary to the inability to reach proximal most sutures transvaginally. Transvaginal Urethrolysis In 1984, Leach and Raz described the transvaginal technique of urethrolysis, and though variations have been published since, it is still the most commonly used today [63]. A midline or inverted U incision approximately 3 cm long is made in the anterior vaginal wall extending from the level of the midurethra to 1–2 cm proximal to the bladder neck. Dissection proceeds laterally along the glistening surface of the periurethral fascia to the pubic bone. The retropubic space is entered sharply by perforating the attachment of the endopelvic fascia to the obturator fascia (Figure 79. The urethra is dissected bluntly and sharply off the undersurface of the pubic bone and completely freed proximally to the bladder neck. Some separation of the urethra from the pubis is done blindly with the Metzenbaum scissors (Figure 79. Care should be taken to stay as close to the underside of the pubis as possible, and manual palpation of this plane along with an awareness of the location of the urethral catheter provides a proprioceptive map in this hard-to-visualize space. If an inadvertent injury to the urethra or anterior bladder wall near the bladder neck is caused, primary repair should be attempted and completion of the procedure should be entertained as further bladder or urethral wall damage can occur. Fistula formation is minor as the area of perforation is well away from the vaginal incision. Once sufficient space is developed in this plane, the remaining adhesions and scar can be swept down bluntly with an index finger. If suspension sutures are felt, a clamp can be used to bring it into view so it can be cut safely. After this initial mobilization, a right-angle clamp can be placed between the pubic bone and the urethra, and a Penrose drain is placed around the urethra. Downward traction is applied on the Penrose drain to aid visualization and all remaining retropubic attachments are dissected free (Figure 79. At this point, the urethra should be freely mobile in all planes, and this can be tested with movement of an intraurethral sound or cystoscope. Cystoscopy should be performed to rule out urethral and/or bladder injury prior to vaginal closure. It is also good practice to assess ureteral integrity by giving intravenous indigo carmine or methylene blue to assure efflux. The endopelvic fascia, periurethral fascia, and vaginal wall are retracted medially to expose the urethra in the retropubic space. With tension on the upper edge, the perineal membrane is perforated and all attachments, scar, and sutures between the pubic bone and urethra are incised sharply with scissors. An index finger can be followed along the underside of the pubis into the retropubic space. With a sweeping motion directed laterally and posteriorly, obstructing bands can be identified and either bluntly or sharply freed. The arms of the sling or suspending sutures are encountered with lateral dissection and should be divided sharply. Once done, urethral mobility is assessed and if adequate, cystoscopy is performed to rule out inadvertent injury prior to vaginal incision closure [64]. A Penrose drain has been placed around the urethra, isolating it from the pubic bone. Resuspension poses the risk of persistent obstruction and if symptoms do not resolve, it is difficult to determine whether this situation resulted from inadequate urethrolysis or resulted from the secondary resuspension. Retropubic Urethrolysis The patient is placed supine on the operating table with the legs slightly spread apart to allow for manual vaginal access. The rectus fascia and muscle are opened in the midline to the level of the pubic symphysis. Any visible and palpable suspension sutures are cut and all attachments and scar between the urethra and pubis are incised sharply. Complications can be minimized by keeping the tips of the scissors up against the pubic symphysis during sharp dissection. Careful attention is paid to the location of the Foley catheter to avoid inadvertent bladder or urethral injury. If bladder injury occurs, prior to repairing it, it may be helpful to leave the bladder open until the dissection is complete to give a constant sense of where the bladder is, with respect to the scar tissue. The index finger of the surgeon’s nondominant hand placed into the vagina helps identify the boundaries of the vagina in relation to the urethra and urethrovesical junction. At the end of the dissection, the urethra, bladder neck, and anterior vaginal wall should be mobile and free from the overlying pubic bone. It should be possible to pass fingers through the abdominal wound, under the pubis, and see your fingers pushing the vaginal skin out in the distal vagina. In cases of severe scarring, it may be necessary to mobilize laterally as far as the ischial tuberosities, creating a paravaginal defect. This defect should be repaired by reapproximating the paravaginal fascia to the fascia of the obturator internus along the arcus tendineus. An omental flap can be brought down and fixed between the pubis and urethra so that recurrent 1220 scarring is minimized [37]. Cystoscopy is performed to rule out urethral injury and confirm efflux of indigo carmine from the ureteral orifices. Recurrent obstruction may result from periurethral fibrosis and scarring, or intrinsic damage to the urethra that has occurred as a consequence of the urethrolysis surgery. Both transvaginal and retropubic approaches were chosen depending on the clinical situation. Obstruction was cured in 96%, but storage symptoms completely resolved in only 12% and were improved and required medication in 69%. In another series, repeat urethrolysis resulted in cure of obstructive symptoms in 72% and storage symptoms in 59% [50]. These data clearly support aggressive repeat urethrolysis in the face of initial failure, at least for retention and incomplete emptying. In general, if an aggressive transvaginal urethrolysis fails, then a retropubic approach may be considered. In cases where the aggressiveness of the initial transvaginal procedure is unknown, or if only a sling incision was performed, then a repeat transvaginal approach may be appropriate. Consideration should also be given to the use of a Martius labial fat pad flap as an interposition layer to decrease recurrent fibrosis and provide some urethral support. The flap is divided midway along its longitudinal axis to allow for circumferential coverage of the urethra, effectively supporting the undersurface and retropubic surface of the urethra [67]. In the 75% of patients that responded, 100% were able to stop all antimuscarinics [68]. However, if there is any concern for residual obstruction or inadequate initial urethrolysis, then a repeat urethrolysis should be considered. The treatment algorithm flowchart summarizes the diagnosis and treatment approach (Figure 79. While keeping in mind the patient’s symptoms and goals, the physician must use careful decision making when assessing, diagnosing, and treating obstruction. Fortunately, the various urethrolysis techniques are highly successful for restoring efficient voiding. Though progress has been made, improved methods of identifying those at risk for obstruction, diagnosing obstruction, and treating troublesome irritative voiding symptoms are warranted.

In the absence of pre-excitation erectile dysfunction heart disease diabetes generic 20 mg erectafil free shipping, most patients in the basal state develop A-V nodal Wenckebach block at paced atrial cycle lengths of 500 to 350 msec (Fig adderall xr impotence erectafil 20 mg buy amex. Occasional young erectile dysfunction nicotine order discount erectafil on-line, healthy patients erectile dysfunction treatment in lucknow 20 mg erectafil order with amex, however erectile dysfunction treatment patanjali order erectafil on line amex, develop Wenckebach block at relatively long-paced cycle lengths, presumably secondary to enhanced vagal tone, while others, with heightened sympathetic tone, conduct 1:1 at cycle lengths of 300 msec. Differences of reported cycle lengths at which Wenckebach block normally appears are almost certainly related to the differences in the basal autonomic tone of the patients at the time of catheterization. There is a correlation between the A-H interval during sinus rhythm and the paced cycle length at which Wenckebach block appears; patients with long A-H intervals tend to develop Wenckebach block at lower-paced rates, and vice versa. In the absence of drugs, this tends to occur in older patients or in young athletic patients with high vagal tone. Although some investigators consider infra-His block abnormal at any paced cycle length,21,25 it can clearly be a normal response at very short cycle lengths. This is a particularly common phenomenon, because if pacing is begun during sinus rhythm, the first or second complex (depending on the coupling interval from the last sinus complex to the first paced complex) acts as a long-short sequence. The long preceding cycle will prolong the His– Purkinje refractoriness; thus, the next impulse will block. The His–Purkinje system may also show accommodation following the initiation of a drive of atrial pacing in an analogous way to the A-V node. Occasionally persistent two-to-one block occurs as a self- perpetuating phenomenon. Repeating the atrial pacing at log cycle lengths with gradual reduction of the paced cycle length will show normal one- to-one conduction up to A-V nodal Wenckebach; thereby demonstrating the P. Prolongation of the H-V interval or infra-His block, however, produced at gradually reduced paced cycle lengths of 400 msec or more are abnormal and probably signify impaired infranodal conduction (see Chapter 5). A: At a paced cycle length of 600 msec, the A-H is 95 msec and the H-V is 50 msec. Shortening the cycle length to 350 msec (B) results in A-V nodal Wenckebach block; that is, progressive A-H prolongation (140, 200, 225 msec) terminating in block of the P wave in the A-V node (no His bundle deflection after the fourth paced beat). The stimulus is delivered, which fails to capture the atrium, which has been previously depolarized by an atrial echo (Ae, arrow) that is due to A-V nodal reentry. The exact proportion of patients demonstrating V-A conduction varies from 40% to 90% and depends on the patient population studied. The incidence of V-A conduction is higher in patients with normal antegrade conduction, although it is well documented that V-A conduction can occur in the presence of complete A-V block if block is localized to the His–Purkinje system. This divergence from the rest of the literature obviously reflected a selected patient population. In 1981, Akhtar74 reviewed his data, which revealed that if retrograde conduction is present, it will be better than antegrade conduction in only one-third of instances. Most of such instances involve patients with either bypass tracts or dual A-V nodal pathways (see Chapters 8 and 10). Our own data have revealed that in 750 patients with intact A-V conduction, antegrade conduction was better (i. These data, which exclude patients with bypass tracts, are comparable to those of Akhtar who only considered patients with intact retrograde conduction. The ability to conduct retrogradely during ventricular pacing is directly related to the presence and speed of antegrade conduction. Patients with prolonged P-R intervals are much less likely to demonstrate retrograde conduction. Thus, A-V nodal conduction appears to be the major determinant of retrograde conduction during ventricular pacing. As with atrial pacing, ventricular pacing is begun at a cycle length just below the sinus cycle length. The paced cycle length is gradually reduced until a cycle length of 300 msec is reached. Further shortening of the ventricular-paced cycle length may also be used, particularly in studies assessing rapid retrograde conduction in patients with supraventricular arrhythmias (see Chapter 8) or during stimulation studies to initiate ventricular arrhythmias (see Chapter 11). During ventricular pacing, a retrograde His deflection can be seen in the His bundle electrogram in the majority of cases. We have used the Bard Electrophysiology Josephson quadripolar catheter for obtaining distal and proximal His deflections (Chapter 1). Using this catheter, we observed a retrograde His potential in 86 of 100 consecutive patients in whom we attempted to record it. Ventricular pacing at the base of the heart opposite the A-V junction (Para-Hisian pacing) facilitates recording a retrograde His deflection, particularly when the His bundle recording is made with a narrow bipolar signal (i. Retrograde His deflections are much less often seen in the presence of ipsilateral bundle branch block. In all instances, V-H (or stimulus-H) interval exceeds the anterograde H-V by the time it takes for the stimulated impulse to reach the ipsilateral bundle branch. This response occurred because the effective refractory period of the His–Purkinje system was 350 msec, which is longer than the paced cycle length. The normal response to ventricular pacing is a gradual prolongation of V-A conduction as the ventricular-paced cycle length is decreased. Retrograde (V-A) Wenckebach-type block and higher degrees of V-A block appear at shorter cycle lengths (Fig. Although Wenckebach-type block usually signifies retrograde delay in the A-V node, it is only when a retrograde His deflection is present that retrograde V-A Wenckebach and higher degrees of block can be documented to be localized to the A-V node (Fig. This extra beat is termed a ventricular echo and is not infrequent during retrograde Wenckebach cycles. Ventricular echoes of this type are due to reentry secondary to a longitudinally dissociated A-V node and require a critical degree of V-A conduction delay for their appearance. Patients with a dual A-V nodal pathway manifesting this type of retrograde Wenckebach and reentry are generally not prone to develop clinical supraventricular tachycardia that is due to A-V nodal reentry (see Chapter 8). Because a retrograde His bundle deflection may not always be observed in patients during ventricular pacing, in the presence of V-A block, localization of the site of block in such patients must be inferred from the effects of the ventricular-paced beat on conduction of spontaneous or P. Thus, one localizes the site of delay by analyzing the level of concealed retrograde conduction. If the A-H interval of the spontaneous or induced atrial depolarization is independent of the time relationship of ventricular-paced beats, then by inference, the site of retrograde block is infranodal in the His–Purkinje system. On the other hand, variations in the A-H intervals that depend on the coupling interval of the atrial complex to the ventricular-paced beat, or failure of the atrial impulse to depolarize the His bundle, suggest retrograde penetration and block within the A-V node (Fig. Another method of evaluating the site of retrograde block in the absence of a recorded retrograde His potential is to note the effects of drugs, such as atropine or isoproterenol, which affect only A-V nodal conduction, on V-A conduction. Improvement of conduction following administration of these drugs suggests that the site of block is in the A-V node. On the bottom, ventricular pacing at the same cycle length is associated with the V-H interval of 70 msec. B: During sinus rhythm at a cycle length of 550 msec, the right bundle branch block is present with an H-V interval of 80 msec. The presence of a retrograde His deflection allowed the site of block to be localized to the A-V node. After the third paced ventricular complex, pacing is terminated (open arrow) and a return beat appears that has the same configuration as the subsequent sinus beat. In contrast to the development of the V-A Wenckebach, if one can record a retrograde His deflection, it is possible to demonstrate that V-H conduction remains relatively intact at rapid rates despite the development of retrograde block within the A-V node (Fig. Refractory Periods The refractoriness of a cardiac tissue can be defined by the response of that tissue to the introduction of premature stimuli. In clinical electrophysiology, refractoriness is generally expressed in terms of three measurements: relative, effective, and functional. The definitions differ slightly from comparable terms used in cellular electrophysiology. Despite the presence of a visible retrograde His deflection the site of block is shown to be the A-V node because antegrade A-V nodal conduction (A-H) depends on the relationship of the sinus beats A to the ventricular complexes. In humans, refractory periods are analyzed by the extrastimulus technique, whereby a single atrial or ventricular extrastimulus is introduced at progressively shorter coupling intervals until a response is no longer elicited. Determining refractoriness at shorter cycle lengths may be useful to assess refractoriness in the heart at rates comparable to those during spontaneous tachycardias. The extrastimulus is delivered after a train of 8 to 10 paced complexes to allow time for reasonable (≥95%) stabilization of refractoriness, which is usually accomplished after the first three or four paced beats. The specific effects of preceding cycle lengths on refractoriness will be discussed later. In most electrophysiologic laboratories, stimulus strength has been arbitrarily standardized as being delivered at twice-diastolic threshold. Some standardization of stimulus strength is necessary if one wishes to compare atrial and/or ventricular refractoriness before and after an intervention. Although use of current at twice-diastolic threshold gives reproducible and clinically relevant information, and has a low incidence of nonclinical arrhythmia induction, the use of higher currents has been suggested. An example of a strength–interval curve to determine ventricular refractoriness is shown in Figure 2-29. Note there is a gradual shortening of measured ventricular refractoriness as the current is increased until the point is reached where the refractory period stays relatively constant despite increasing current strengths. The determination of such curves, however, may be quite useful in characterizing the effects of antiarrhythmic agents on ventricular excitability and refractoriness. The safety of using high current strengths, particularly when multiple extrastimuli are delivered, is questionable because fibrillation is more likely to occur when multiple extrastimuli are delivered at high current strengths. The determination of antegrade and retrograde refractoriness with atrial extrastimuli and ventricular extrastimuli, respectively, is demonstrated in Figures 2-31 and 2-32. A–E: The effects of progressively premature atrial extrastimuli (S2) delivered during a paced atrial cycle length (S1-S1) of 600 msec. There is progressive prolongation of A-V nodal conduction (increase in A2-H2; A–C) followed by block in the A-V node, (D) and atrial refractoriness, (E) at shorter coupling intervals. Cycle Length Responsiveness of Refractory Periods Determinations of refractoriness should be performed at multiple drive cycle lengths to assess the effect of cycle length on the refractory periods. An atrial premature stimulus (A2), delivered at a coupling interval (Al-A2) of 395 msec, conducts with an Hl-H2 interval of 420 msec, resulting in the development of right bundle branch block and H2-V2 prolongation to 60 msec. B: At a shorter cycle length of 500 msec, a premature atrial impulse with an identical H1-H2 of 420 msec is conducted without aberration or H2-V2 prolongation. Thus, the relative refractory period of the His–Purkinje system is shortened as the paced cycle length decreases. Although the basic drive cycle length affects the refractory periods in this predicted way, abrupt changes in the cycle length may alter refractoriness differently. The effect of abrupt changes in drive cycle length and/or the effect of premature impulses on subsequent refractoriness of His–Purkinje and ventricular tissue has recently been studied. In both instances, the ventricular refractoriness seems to be more closely associated with the basic drive cycle length; that is, it demonstrates a cumulative effect of preceding cycle lengths, whereas the His– Purkinje system shows a marked effect of the immediately preceding cycle length(s). However, if a pause equal to the drive cycle length is delivered after the first premature stimulus and then refractory periods again determined following this new S1′ interval (Fig. In contrast, when the refractory period of the first premature stimulus is tested without a new pause, His–Purkinje refractoriness is shortened. Divergence between refractoriness of His–Purkinje system and ventricular muscle with abrupt changes in cycle length. Postextrasystolic alterations in refractoriness of the His–Purkinje system and ventricular myocardium in man. These findings may also explain some of the variability of initiation of tachycardias depending on preceding cycle lengths. The mechanism of these abnormalities has not been well worked out but appears related to the diastolic interval between action potentials of premature and drive beats (Fig. As can be seen in Figure 2-36, although the drive cycle length affects the action potential during that drive, the diastolic interval (the interval from the end of the action potential to the beginning of the next action potential) can be markedly affected by short- long, or long-short intervals, which can affect the refractory period of the subsequent complex. The role of the diastolic interval on ventricular refractoriness has been studied by Vassallo et al. In this study, we evaluated the effect of one and two extrastimuli on subsequent ventricular refractoriness using a protocol that kept the coupling interval of the first and second stimulus equal (S1-S2 = S2-S3). Because a single premature stimulus (S2) can shorten ventricular refractoriness, as measured by S3, keeping S1-S2 and S2-S3 equal would directly assess the effect of the diastolic interval on refractoriness. Using this method, we clearly showed that the refractory period following one extrastimulus (S2) was shorter than a refractory period following two extrastimuli (S2, S3) delivered at the same coupling intervals. This was probably related to an increase in the diastolic interval preceding S3 (Fig. This finding implies that the diastolic interval is probably the key determinant in alterations in refractoriness in response to sudden changes in cycle length and suggests that the His–Purkinje system and ventricular muscle differ more quantitatively than qualitatively. Because the diastolic interval influences the response of both His–Purkinje system and ventricular refractoriness to single extrastimuli, what is the cause of the “quantitative” differences? Demonstration of the effects of the diastolic interval on refractoriness of ventricular muscle requires short coupling intervals. In 1987 Marchlinski88 demonstrated that very short drive cycle lengths and coupling intervals produce oscillations of ventricular refractoriness analogous to that shown for the His–Purkinje system. Thus, the diastolic interval appears to be the major determinant of the refractory period following extrastimuli in both structures. Differences in the basic action potentials of ventricular muscle and His–Purkinje fibers are responsible for the apparent differences in their response to changes in cycle length and premature stimulation. A–C: The stimulus-to- stimulus intervals (in milliseconds) are shown along the top of action potentials. Effects of sudden cycle length alteration on refractoriness of human His–Purkinje system and ventricular myocardium. During a paced cycle length of 400 msec, refractoriness was determined to be 220 msec. A: Double extrastimuli (S2 and S3) are delivered with an S1-S2 coupling interval equal to 260 msec (diastolic interval of 40 msec).
