These include (1) urethral involvement, which makes the repair more complex as the urethra needs to be reconstructed and continence maintained despite the loss of the continence mechanisms, (2) severe vaginal scarring, making access to the fistula for repair difficult or impossible without relaxing incision and increases the likelihood of ongoing incontinence, (3) the size of the 1603 fistula, and (4) finally, the amount of bladder tissue loss, reflected in a small remaining bladder capacity [23,45,46]. It looks at the site of the fistula in relation to the external urethral meatus, its size, and the amount of scarring. It is difficult to measure bladder volume before repair so site, size, and scarring are examined. The measurements of site and size are objective, but the measurement of scarring tends to be more subjective (site size scarring, Goh classification Table 109. The Waaldjik system concentrates more on the urethra and if it is a circumferential defect or not . There has been one study comparing the prognostic value of both systems and concluded that the Goh system had significantly better predictive value of obstetrics fistula closure . The rationale behind this is to allow the necrotic tissue to slough away and the often suboptimal tissue that remains to recover before attempting to operate. There has been one compelling paper advocating earlier repair, to repair as soon as the dead tissue has come away, with active debridement while waiting. This affords a good success rate and enables the woman to regain health more quickly, before she is made an outcast . However, the tissues are much more difficult to handle at this stage, with the tissues tearing and sutures cutting out. This series was done by an extremely experienced fistula surgeon and the results are yet to be replicated in other units and with more inexperienced surgeons. It would be prudent for the inexperience fistula surgeon to rely on the traditional teaching of waiting for 3 months. If the fistula is iatrogenic in an ischemic operative field, such as a cesarean after 2 days of labor, it could be argued to follow the same guidelines as for obstructed labor fistula. With this management, up to 20%–40% of smaller vesicovaginal fistulae will heal [52,53]. Doctors with gynecological training often favor the vaginal route, while doctors with urological training favor the abdominal route. The abdominal route might be found easier with high vault, juxtacervical, or vesicovaginal/vesicouterine fistulae. Even these cases can be confidently managed vaginally with experience, which has obvious benefits postoperatively. A recent publication comparing vaginal to abdominal route of repair showed that the abdominal route seemed to be associated with higher rates of closure. However, of the cohort, only 5% of cases underwent an abdominal repair and were more likely to be higher in the birth canal, which have a better outcome than those lower in the birth canal anyway [23,54]. The choice of route of repair seems to be reflected more on the surgeon’s training and experience. Wide mobilization of the bladder off the vagina/cervix/uterus and surrounding tissues 3. Dye test to confirm watertight closure of the bladder Exposure of the Fistula and Protection of the Ureter The patient is placed in the exaggerated lithotomy position with the patients’ buttocks over the end of the operating table. The table is placed in steep Trendelenburg, which will bring the anterior vaginal 1605 wall perpendicular to the surgeons gaze. In up to 28% of patients, there is significant vaginal scarring that renders it impossible to insert a speculum . Lateral relaxing incisions are necessary to release the scar, expose the fistula, and then be able to insert the speculum for adequate exposure. In all trigonal and supratrigonal fistulae, except the very small, the ureters should be identified and catheterized (Figure 109. This can be done through the fistula and the catheter ends advanced through the urethra. This is to prevent inadvertent injury during dissection and inadvertent suturing of the ureter during repair. Wide Mobilization of the Bladder off the Vagina/Cervix/Uterus and Surrounding Tissues The hallmark of successful vesicovaginal fistula surgery is wide mobilization of the bladder, releasing it from scarred attachments to the surrounding structures and excision of the scar tissue from the bladder and surrounds, so good viable tissue is approximated in the repair. Tension-Free Closure of the Bladder Once the bladder has been successfully mobilized, the bladder is sutured together under no tension. The bladder is closed with interrupted sutures (2-0 polyglycolic acid) approximately 4 mm apart. Dye Test to Ensure a Watertight Closure 1606 To ensure that a watertight closure has been achieved, 50–100 mL of dilute colored fluid (dilute gentian violet is often used) is instilled into the bladder (Figure 109. To Graft A contentious issue in fistula surgery is whether to use an interpositional graft. It has been traditionally taught this aids healing by bringing a fresh blood supply to the compromised tissues surrounding the fistula. The most common graft used is the Martius fibrofatty graft harvested from the labia majora. Other grafts have been described, being of the gracilis muscle, peritoneum, omentum, and broad ligament. One small study did show an increased success rate with using the Martius graft . However, based on a large study done in Ethiopia , many fistula surgeons no longer use grafts routinely and note similar success rates to graft interposition. There are instances when a graft may be advantageous, such as for a patient who has had multiple unsuccessful operations or when the tissues are very thin and fragile, say with the complete reconstruction of a neourethra. To form a Martius graft, an incision is made longitudinally along the bulge of the labia majora. The fat underneath is exposed and a flap of fat developed from anterior to posterior with the pedicle still being attached posteriorly. A tunnel is created into the vagina superficial to the inferior pubic ramus, beneath the bulbocavernosus and vaginal skin. The fat is introduced into the vagina and placed over the fistula repair with anchoring sutures (Figure 109. The vaginal and labial skins are repaired, taking precaution to prevent hematoma formation. An anatomical closure may be quite possible, but a functioning closure is very difficult. Flaps are then created and sewn over a Foley catheter and this delicate structure is anastomosed to the bladder. A graft is sometimes placed to help support and nourish this frail construction, a gracilis graft has been described , but if a graft is used, the Martius graft is the common choice (as mentioned earlier). A longitudinal flap is created after dissecting the bladder off the symphysis pubis and then advancing this toward the urethral meatus. The flap sewn into a tube over a Foley catheter, a graft placed, and the vagina repaired . This is often not possible with obstetric fistulae as these types of fistulae often result in much loss of the bladder tissue; this procedure will thus decrease the size of an already small bladder. When a new urethra is made from remaining paraurethral tissues, urethral strictures may form in the long term resulting in urinary retention and voiding disorders.

The immediate course of the injury is that 3–10 days postdelivery, a necrotic slough is extruded through the vagina, and the vesicovaginal fistula is exposed rendering her completely incontinent of urine, leaking every minute of the day and night (Figure 109. Rarely, if the fistula is very small, she can describe symptoms more like stress urinary incontinence, but leaking from the vagina rather than the urethra. If she has sustained similar injuries to the posterior compartment, she is also rendered incontinent of feces and flatus per vagina. It is easy to think of the obstetric fistula as merely just a hole in the vagina to the bladder and perhaps the rectum. However, unlike iatrogenic surgical fistula that is usually just a discreet injury, the pathology of the obstetric fistula is broader, and the term “field injury” has been coined to refer to the range of injuries. The ischemic process affects not only the tissues of the genitourinary tracts and bowel but also all the other tissues in 1598 the mothers’ pelvis, that is, nerves, muscles, and bones. This results in primary conditions, those associated with the etiology of obstetric fistula and the ischemic process within the mothers’ pelvis over a broad area, and also secondary conditions—conditions delayed, arising later as a result of the incontinence or scarring within the pelvis. Primary Conditions Vesicovaginal Fistula The level of impaction during labor determines the site of injury. If the impaction occurs at the pelvic inlet, the vesicovaginal fistula may be juxta- or even intracervical  (Figures 109. The urethra is injured in 28% of cases with 5% of patients in Ethiopia having the urethra completely destroyed . This has prognostic indications as the mechanisms for continence in the female have been destroyed [17,23,24]. Ureteric Injury In a small number of obstetric fistula cases, the lower part of the ureter can be involved. The whole ureterovesical junction is necrosed and sloughed away, leaving the vesicovaginal fistula with the ureter draining outside of the bladder straight into the vagina. It is becoming more common to see isolated ureterovaginal fistulae after cesarean section or cesarean hysterectomy, more commonly on the left, and these are iatrogenic, occurring at the time of operative delivery [2,25]. Rectovaginal Injuries A rectovaginal fistula occurs if the presenting part is impacted against the sacrum during labor, causing ischemic necrosis of the rectovaginal septum. It has various reported prevalence and seems to vary geographically, ranging between 6% (B. If present, it usually occurs in conjunction with a vesicovaginal fistula, rarely presenting in isolation . The status of the anal sphincter should always be noted as there may be residual flatal or fecal incontinence even after repair . Reproductive Tract The tissues of the vagina are obviously injured, but in some cases, the whole vagina has necrosed, leaving little or no identifiable remaining vaginal epithelium (Figure 109. The cervix is often torn or partly necrosed and fistula surgeons testify that it is rarely that one will see an uninjured cervix. Muscles The muscles of the pelvic basin are often affected by a neuropathy, directly weakened by the ischemic process or even completely destroyed. A recent ultrasound study of the levator muscle complex in obstetric fistula patients showed little muscle loss and little denervation , but certainly in extensive injuries, an “empty pelvis” is all that remains. Bones A series by Cockshott performed x-rays on 312 women with obstetric fistula and found that 32% had some x-ray abnormality, ranging from bony resorption, bony spurs, obliteration or separation of the symphysis pubis . Nerves It has been quoted that between 20% and 65% of obstetric fistula, patients will have some form of peroneal neuropathy manifesting as bilateral or unilateral foot drop [21,29]. There are currently three theories as to its etiology: a prolapsed intervertebral disc, direct compression of the fetus on the lumbosacral trunk during labor, or impingement of the common peroneal nerve as it transverses the head of fibula while the patient squats for prolonged periods during labor [30,31]. Waaldjik and Elkins commented that most patients do improve with time with 13% still showing some signs at 2 years . Secondary Conditions Social Consequences The consequences of complete incontinence for a woman in the developing world, where the status of women is usually low, are far reaching. Over half are divorced by their husbands who feel that the affected woman is now unable to fulfill her marital duties and unable to bare children . Her incontinence has other consequences as she is now in urine-soaked clothes, unable to clean herself or her attire. She cannot go to church or mosque to worship, to the market, or to the well to draw water. Mental Health It is becoming more apparent that mental health issues in obstetric fistula patients are a significant disease burden [32–36]. Similarly, in Kenya, 17% of patients had suicidal ideations before receiving treatment, 73% were depressed, and 26% severely depressed . If, however, the patient is cured completely by the operation and has no residual incontinence, the percentage screening positive returns to the background positive rate from the general population [33,36]. Malnutrition Malnutrition results from isolation as the patient may be fed and cared for inadequately by a relative in a small room or hut. Upper Renal Tract Damage One study from Nigeria looking at intravenous pyelograms in women with fistula revealed 49% of patients sustained upper renal tract damage. The most common consequence is hydronephrosis (34% of women), but the damage may progress all the way to nonfunctioning kidneys . This is presumably due to scarring partially or totally occluding the lower ureter causing obstructive uropathy and partly due to repeated ascending infections. Bladder Stones The constant leakage of urine leads many women to drink less water and, hence, produce less urine. The concentrated urine might collect in pockets of scar, vagina, or bladder and, with time, form calculi, causing pain, infection, and increased odor. Occasionally, the woman herself or perhaps a local healer will insert foreign bodies into the vagina to try and stem the flow. Such foreign bodies have included stones, rags, or plant material, acting as a nidus for calculi formation. The ammonias and phosphates can encrust on the skin, causing excoriations, secondary infections, and areas of tender hyperkeratosis. Much thought has gone into treating this condition coined the “urine dermatitis,” but the most expedient way to just to ensure that the urine is not in contact with the skin is by applying barrier ointments such as Vaseline or better by closing the fistula, making the patient continent (Figure 109. Reproductive Outcomes After fistula occurrence, up to 44%–63% may suffer from amenorrhea [21,38,39]. Surely, some are due to stresses of the delivery and the resulting social isolation. It is thought that some will have focal anterior pituitary necrosis from shock during the long labor .

However, this measurement technique is dependent on the position of the detector in relation to the leaked urine as well as the position of the patient. Perineal temperature rises when a patient sits, meaning explicit instructions are necessary. When used as a separate method, this test gives a rough estimation of the amount of urine that has been lost, but it gives little information about the timing of urine leakage. However, combining this with placing a conductance catheter gives the necessary additional information on the episode of urine leakage. In the event of urine passage, there is an increased conduction and a larger current passes across the electrodes. However, exact localization is key and should be monitored closely at the start of the assessment. This document covers different aspects such as technical considerations and suggestions and both clinical and scientific reports for ambulatory urodynamics. In this chapter, we will discuss the parts of this report most relevant for clinical purposes. The versatility of ambulatory urodynamics is associated with a greater risk of losing signal quality. In the absence of continuous supervision, stringent checks on signal quality should be incorporated in the measurement protocol. At the start of monitoring, these should include testing of recorded pressure online by coughing and abdominal straining in the supine, sitting, and erect positions. The investigator must be convinced that signal quality is adequate before proceeding with the ambulatory phase of the 507 investigation. Prior to termination of the investigation, and at regular intervals during monitoring, similar checks of signal quality such as cough tests should be carried out. Such tests will serve as a useful retrospective quality check during the interpretation of traces. The following considerations must be taken into account when using microtip transducers: Transducers should be calibrated before every investigation. All transducers must be “zeroed” at atmospheric pressure before insertion of the catheters. Urethral Pressure and Conductance The recording of urethral pressure is a qualitative measurement with emphasis on changes in pressure rather than absolute values. The use of urethral electrical conductance to identify leakage in association with pressure monitoring facilitates interpretation of urethral pressure traces. Precise positioning and secure fixation of catheters are essential to maintain signal quality (Figures 35. Methods that have been used include adhesive tape, suture fixation, and specially designed silicone fixation devices. The yellow catheter on the top is used for measuring intravesical and urethral pressures. Recording of Urinary Leakage The method of urine leakage determination should be recorded. It should be stated whether the urinary leakage is recorded as a signal with the pressure measurements or is dependent on the subject pressing an event marker button or completing a urinary or leakage weight diary (Figure 35. Instructions to the Patient Detailed instructions as to recording of symptoms, identification of catheter displacement, and hardware failure should be given to the patient. It is the recommendation that such verbal instructions should be reinforced by written instructions, and, in addition to the hardware built into the system, the patient is provided with a simple diary to record events. The specific points that should be addressed with regard to pressure measurement are as follows: 509 Figure 35. If the technical quality of the traces is less than perfect, then, although the investigation may yield valuable clinical information, the information that can still be derived from the traces is very much dependent on the experience of the team and the person responsible for the interpretation of the assessment. Phase Identification Depending on the purpose of the investigation, markers must be placed to identify voluntary voids and allow differentiation of such events from involuntary events, which may be associated with changes in recorded pressure. The protocol of the investigation should state specifically the point at which the markers identifying commencement and cessation of a voluntary void are placed. Analysis of the voiding phase follows the same principles and terminology used during conventional pressure–flow investigation. The system is used to check catheter position before fixation and connection to the portable unit. In addition, data from the portable recording unit are transferred to this system after the ambulatory measurement has ended. In addition, it has proven very valuable as a double check for both patient and equipment compliance. Typical events occurring during the filing phase are detrusor contractions, urethral relaxation, and episodes of urgency and incontinence. Catheters are placed in the bladder, urethra, and rectum and brought into optimal position. After fixation, catheter positions should be checked again and, in case necessary, corrected for optimization of the pressure–flow traces. Procedure The patient should use the timer on the ambulatory box, not her own watch. In the event of a toilet visit, the button is pressed when entering the bathroom or at the starting point of voiding and pressed again once voiding has finished. When fluids are consumed, or during an episode of urgency, the relevant buttons are used. Instructions for the use of the event buttons should be included on the diary sheet, as should the instructions on how to fill out the diary. The traces and diary can be interpreted with the patient still present or at a later stage. If the traces are interpreted in a later stage, the diary must have been filled out correctly by the patient and event markings been recorded correctly. If symptoms suggesting cystitis are persistent or urine becomes offensive, the patient should seek advice from her doctor. No significant difference was seen when comparing stress incontinence rates in both groups (p = 0. The difference in observations between both assessment types could be explained by the technique used. However, it cannot be excluded that the vesical catheter itself is a nonphysiological trigger resulting in a higher incidence of detrusor overactivity during ambulatory urodynamics . The fact that the bladder produces involuntary detrusor contractions in response to the small flexible catheters during an ambulatory urodynamic measurement itself might indicate a higher excitability of the bladder sensory function or a decreased central inhibition of the urethra–detrusor facilitative reflex contractions in the filling phase .
