Vesicovaginal fistula repair closes an abnormal opening between the bladder and the vagina, and when performed by an experienced surgeon, it succeeds in the vast majority of cases. The repair can be done through the vagina, through the abdomen, or with robotic assistance, depending on the fistula’s size, location, and cause. While the surgery itself is well established, the full picture of recovery is more complicated than a single procedure: residual urinary leakage, psychological distress, and the question of future pregnancies all shape what “successful repair” actually means for the person living with it.
Why the Causes Matter for Repair
The reason a fistula formed in the first place heavily influences how it gets fixed. In low-resource countries, the overwhelming cause is prolonged obstructed labor, which accounts for roughly 95% of cases. In wealthier countries, the picture flips: about 83% of fistulas follow surgery, most commonly hysterectomy, with radiation therapy and infection making up most of the rest.1PubMed. The Aetiology, Treatment, and Outcome of Urogenital Fistulae Managed in Well- and Low-resourced Countries: A Systematic Review Obstetric fistulas tend to involve more tissue damage, scarring, and sometimes loss of healthy tissue around the bladder neck and urethra. Iatrogenic fistulas from surgery are often smaller, more precisely located, and surrounded by healthier tissue, which generally makes them easier to close.
This distinction shapes nearly every decision that follows: the timing of repair, the surgical route, whether extra tissue is brought in to reinforce the closure, and what complications to anticipate afterward.
When Catheter Drainage Alone Can Work
Not every fistula requires an operation. For newly formed, small fistulas, continuous bladder drainage with an indwelling catheter for three to four weeks, combined with antibiotics to prevent infection, can allow the opening to heal on its own.2PubMed Central. Minimally invasive complete urinary tract drainage in the treatment of vesicovaginal fistula: A case report The idea is straightforward: keep urine from flowing through the fistula so the edges can close naturally. This conservative approach works best when the fistula is discovered soon after it forms, is less than a centimeter or so in diameter, and has no significant surrounding tissue damage or infection.
If the fistula persists after a trial of catheter drainage, surgical repair becomes the next step. The traditional teaching was to wait three to six months before operating, giving inflammation time to settle. More recent practice has shifted toward earlier surgery once the tissue looks healthy and free of active infection, though the exact timing still varies by surgeon and clinical scenario.
Transvaginal Repair and the Latzko Technique
The most commonly performed repair for many fistulas is the Latzko technique, a transvaginal approach first described nearly a century ago and still considered highly effective. It involves separating the vaginal lining from the underlying tissue around the fistula, removing the epithelium that has grown into the fistula tract, and then closing the defect in several layers with absorbable sutures.3PubMed Central. The Latzko: A high-value, versatile vesicovaginal fistula repair The technique is versatile enough to handle even complex situations, including fistulas that appear alongside pelvic organ prolapse or after complicated urologic surgery.
A modified version of the Latzko approach involves mobilizing the vaginal mucosa more extensively and closing the tissue layers individually. Series using this modified technique report durable results with no fistula recurrence and no significant complications.4PubMed. Transvaginal Repair of Apical Vesicovaginal Fistula: A Modified Latzko Technique-Outcomes at a High-volume Referral Center The transvaginal route avoids an abdominal incision entirely, which means shorter hospital stays, less blood loss, and faster recovery. For fistulas located high in the vagina near the vaginal apex, where post-hysterectomy fistulas commonly sit, the Latzko approach is especially well suited.
One trade-off worth understanding: the Latzko repair works by partially closing off the upper vagina, which shortens vaginal length somewhat. For many patients this has no functional consequence, but it is a consideration that surgeons discuss before proceeding.
When an Abdominal or Robotic Approach Makes More Sense
Some fistulas are not reachable through the vagina, or they involve enough tissue damage that the surgeon needs the wider exposure an abdominal approach provides. Traditionally this meant open surgery through a large incision, but laparoscopic and robotic techniques have steadily gained ground. A prospective comparison of robotic versus conventional laparoscopic repair found that both achieved comparable success in closing the fistula, but the robotic group had shorter operating times (around 150 minutes versus 229 minutes), less blood loss, and shorter drainage times.5Gynecologic Robotic Surgery. Robot assisted laparoscopy vs laparoscopic transabdominal vesicovaginal fistula repair: a prospective comparison
Robotic repair also opens up creative options for reinforcing the closure. One center reported success using a peritoneal tissue flap shaped during the robotic procedure itself, achieving successful repair in all 15 patients with minimal blood loss and no conversions to open surgery.6PubMed Central. Robot-assisted vesicovaginal fistula repair with “Rainbow-shaped” peritoneal flap: a single-center experience Another technique uses small fat-bearing tissue from the sigmoid colon as an interposition layer during robotic repair, with successful outcomes and most patients going home the day after surgery.7PubMed Central. Robotic Repair of Supratrigonal Vesicovaginal Fistula with Sigmoid Epiploica Interposition
The choice between vaginal, abdominal, laparoscopic, and robotic repair is not one-size-fits-all. It depends on where the fistula sits, how much scarring surrounds it, whether previous repairs have failed, the surgeon’s experience, and what equipment is available. In high-volume referral centers with robotic platforms, the trend is clearly toward minimally invasive abdominal approaches for fistulas that cannot be reached vaginally. In settings without that technology, open abdominal repair remains entirely appropriate.
When Extra Tissue Is Brought In
Sometimes the tissue around a fistula is too thin, scarred, or poorly supplied with blood to hold a repair on its own. In these cases, surgeons place a flap of healthy tissue between the bladder and vaginal closures to add a fresh blood supply and an extra barrier. The best-known option is the Martius flap, first described in 1928, which harvests tissue from the labial fat pad and tunnels it into the repair site. Cure rates with this flap have been reported as high as 97% for fistulas located in the lower part of the vagina.8Medical Research Innovations. Martius flap repair of a vesicovaginal fistula: Case report and review
But here is where a common assumption deserves pushback: a flap is not always necessary, and not having one does not doom the repair. A comparison of transvaginal repair with and without a Martius flap for simple fistulas found essentially equal success rates, with no statistically significant difference between the two groups.9Annals of Punjab Medical College. Comparison of Transvaginal Repair of Vesicovaginal Fistula with and without Martius Flap When the surrounding tissue looks well vascularized and healthy, a straightforward layered closure works just fine.10PubMed Central. Management of vesicovaginal fistulas after gynecologic surgery Flaps earn their place in more complex scenarios: recurrent fistulas, radiation-damaged tissue, large defects, or repairs where the tissue quality is poor.
Other flap options include omental flaps (using fatty tissue from the abdomen), gracilis muscle flaps from the inner thigh, and peritoneal flaps. The choice depends on the surgical route and the location of the fistula.
Radiation-Induced Fistulas Are a Different Beast
Fistulas caused by radiation therapy to the pelvis deserve separate mention because they are considerably harder to repair. Radiation damages blood vessels and leaves tissue chronically fragile. In one large series of 216 patients with radiation-induced fistulas, only about 48% achieved a successful repair on the first attempt, and more than half remained incontinent after their initial surgery.11PubMed Central. Management of radiation-induced vesicovaginal fistula That is a striking contrast to the success rates typically seen with post-surgical or obstetric fistulas, and it underscores why radiation-damaged tissue often requires tissue flaps and sometimes urinary diversion rather than direct repair.
How Long the Catheter Stays After Surgery
After repair, a catheter keeps the bladder continuously drained so the healing closure is not stressed by urine. The traditional approach was to leave it in place for 14 days, but recent randomized trials have tested whether shorter durations work just as well. A non-inferiority trial comparing 10-day versus 14-day catheterization found cure rates of 97% and 93% respectively, with the shorter duration performing at least as well. A larger trial comparing 7 days to 14 days found no significant difference in fistula breakdown within three months.12PubMed Central. Repair of Vesicovaginal Fistulae: A Systematic Review A systematic review of shorter versus longer catheterization confirmed no meaningful difference in the risk of repair failure.13PubMed. Systematic review of shorter versus longer duration of bladder catheterization after surgical repair of urinary obstetric fistula
This matters practically because every extra day with a catheter increases the risk of urinary tract infection, causes discomfort, and in low-resource settings may mean additional days away from home. Medications that relax the bladder muscle are also commonly used in the postoperative period to reduce involuntary bladder contractions that could put pressure on the repair.14PubMed Central. Vesicovaginal fistula: Review and recent trends
What Predicts Whether the Repair Will Hold
A systematic review of factors predicting fistula recurrence identified several consistent risk markers. Large fistulas (greater than two to three centimeters) carried elevated odds of failure. Severe scarring around the fistula was among the strongest predictors, with odds ratios ranging from roughly 3 to 12 across studies. Involvement of the urethra or bladder neck, the presence of multiple fistulas, a history of prior failed repairs, and longer duration of the fistula before treatment all increased the risk of recurrence.15PubMed Central. Predictors of recurrence after vesicovaginal fistula repair: a systematic review of surgical and patient-related factors
Classification systems help surgeons anticipate these risks. The two most widely used are the Waaldijk and Goh systems, both designed primarily for obstetric fistulas. A comparison at a high-volume center in the Democratic Republic of Congo found that Goh’s system was significantly better at predicting whether a fistula would successfully close.16PubMed. Comparison of two classification systems for vesicovaginal fistula These classification tools consider factors like location relative to the urethra, fistula size, and the degree of scarring, giving the surgical team a framework for planning the approach and setting realistic expectations.
Successful Closure Does Not Always Mean Dry
One of the most important things to understand about fistula repair is that closing the hole and stopping all urinary leakage are not the same thing. Among women whose fistulas were successfully closed in one large cohort, about 23% still experienced residual urinary incontinence.17PubMed Central. Identifying Patients With Vesicovaginal Fistula at High Risk of Urinary Incontinence After Surgery This persistent leaking is typically stress incontinence, triggered by coughing, sneezing, or physical exertion, rather than urgency-type leaking. A detailed study of Ethiopian women with successful fistula closure found that nearly all had stress incontinence on testing, and about half still reported constant leakage despite the fistula being anatomically closed.18PubMed. Characteristics of persistent urinary incontinence after successful fistula closure in Ethiopian women
The reason is that prolonged pressure from obstructed labor or radiation can damage the sphincter mechanism and the nerves that control bladder function, not just the bladder wall itself. Closing the fistula repairs the structural opening but cannot always undo the broader injury to the continence mechanism. This is why a woman can be told her surgery was successful and still find herself dealing with leaking. It is not a failure of the operation; it is a limitation of what the operation can fix.
Psychological Recovery After Repair
Women living with vesicovaginal fistulas in low-resource settings often endure years of social isolation, shame, and economic hardship before reaching a surgical center. In one study, participants had lived with their fistulas for an average of 11 years before repair. Psychological distress at baseline was high, with significant depression and post-traumatic stress symptoms. After surgery, all measures of psychosocial functioning improved. But the improvement was closely tied to whether leaking stopped: women who still experienced incontinence after repair reported significantly higher depression and PTSD symptoms than those who were fully dry.19PubMed Central. Psychological Symptoms and Social Functioning Following Repair of Obstetric Fistula in a Low-Income Setting
This link between residual leaking and psychological distress reinforces why addressing continence problems after fistula closure matters so much. Rehabilitation programs that combine health education, physical therapy, psychosocial counseling, and economic support have shown improvements in both physical and mental health outcomes.20PubMed Central. Rehabilitation and reintegration programming adjunct to female genital fistula surgery: A systematic scoping review These programs are concentrated in sub-Saharan Africa, where the burden of obstetric fistula is highest, and they represent an important shift toward treating the whole person rather than just the anatomical defect.
Pregnancy After Fistula Repair
A question that weighs heavily on many women after repair is whether they can safely become pregnant again. The answer is guarded. A longitudinal study in Guinea followed women after fistula repair and found that of 50 who delivered, only nine had an elective cesarean section, which is the recommended delivery method to protect the repair. There were 12 stillbirths, seven fistula recurrences related to delivery, and one maternal death.21The Lancet Global Health. Recurrence of fistula, pregnancy, and childbirth after female genital fistula repair in Guinea: a longitudinal study
These numbers are sobering and highlight two problems at once. First, vaginal delivery after fistula repair carries real risk of reopening the fistula. Second, in settings where the original fistula was caused by lack of access to cesarean delivery, the same access problem often persists for the next pregnancy. Planned cesarean delivery before labor begins is strongly recommended for women who have undergone fistula repair, but ensuring access to that care remains a systemic challenge.
Imaging and Surgical Planning
Before any repair, the surgical team needs a clear picture of the fistula’s exact location, its path through the tissue, and whether there are multiple openings. Physical examination and cystoscopy (looking inside the bladder with a camera) are the starting points, but they do not always tell the full story, especially for complex or recurrent fistulas. Cross-sectional imaging with CT or MRI has largely replaced older contrast studies, providing detailed anatomic and functional information that directly guides the choice of surgical route and technique.22PubMed Central. Elucidating vaginal fistulas on CT and MRI MRI is particularly useful for distinguishing between different types of vaginal fistulas when the clinical picture is unclear and for evaluating the condition of surrounding tissues in radiation-damaged cases.
Prevention in Low-Resource Settings
The global burden of obstetric fistula is fundamentally a problem of access to care. Analyses of prevention strategies consistently point to the same core interventions: better monitoring of labor, timely access to emergency obstetric services including cesarean delivery, competent medical management during and after obstructed labor, and the development of specialist fistula repair centers in areas where fistula prevalence is high.23PubMed. Preventing obstetric fistulas in low-resource countries: insights from a Haddon matrix Policy recommendations have also emphasized expanding public awareness and making women’s reproductive health a higher priority for both developing-country governments and international aid organizations.24The Lancet. Obstetric vesicovaginal fistula as an international public health problem
Training surgeons who can perform these repairs is itself a bottleneck. Simulation models for transvaginal fistula repair have been developed and tested by experienced urogynecologic surgeons, who found the models useful for practicing key steps like identifying and closing the fistula, though certain aspects like cystoscopy were not well replicated.25PubMed. Vesicovaginal Fistula Repair Simulation Model and Hierarchical Task Analysis Building surgical capacity in the regions where fistula is most common remains one of the hardest and most important pieces of the puzzle.
Experimental Approaches on the Horizon
Researchers have begun exploring whether injecting a patient’s own cells into a fistula site could promote healing, particularly for small or recurrent fistulas. An early randomized study in an animal model tested autologous cell injections and found that one of four treated fistulas closed, compared to none in the control group. However, microscopic examination of the tissue showed no clear difference in tissue composition between the two groups, and both showed signs of healing regardless of treatment.26PubMed Central. Treatment of Vesicovaginal Fistulas With Autologous Cell Injections—A Randomized Study in an Animal Model This is very early-stage science, and cell-based therapies for fistula repair remain far from clinical use. But the interest reflects a broader push in regenerative medicine to find alternatives for patients in whom conventional surgical repair has failed repeatedly.
