Female Fistula Repair
Female genitourinary fistula repair is organized by the tract involved (vesicovaginal, ureterovaginal, urethrovaginal, vesicouterine, rectovaginal) and by the surgical approach that accesses it best. The recurring decisions are route (transvaginal, transabdominal or combined), timing (immediate, early or delayed), interposition flap need (none, Martius, gracilis or omentum), and whether a protective diversion is required.
Decision Framework
In developed countries most VVF follows gynecologic or pelvic surgery. The EAU cites hysterectomy for benign disease (60-75%), hysterectomy for malignancy (30%) and cesarean delivery (6%) as the main causes of postoperative VVF in developed countries, and reports a 0.1-4% risk of pelvic organ fistula following hysterectomy. Obstructed labor remains the usual cause in the developing world. Radiotherapy-related fistulas do worse with the same techniques, and a fistula after primary radiotherapy may signal tumor recurrence.[1] Small series suggest no difference in success between early (within 4 weeks) and delayed (after 3 months) VVF closure, and spontaneous closure can occur, particularly with small fistulas (<1 cm in the cited reports).[1]
Define the involved organs, viable tissue, sphincter function, obstruction, previous repairs and patient goals. Prior surgery and obstetric injury produce different defects; radiotherapy and malignancy require particular attention to healing and reconstructability. For VVF, choose vaginal access when it permits adequate exposure and closure; an abdominal or combined route may be needed for inaccessible defects or associated ureteral reconstruction. A high or trigonal location alone does not mandate abdominal repair.[1]
Clinical Clues and Evaluation
| Presentation | Consider | Evaluation guided by the anatomy |
|---|---|---|
| Continuous vaginal urine leakage with a positive bladder dye test | Vesicovaginal fistula (VVF) | Pelvic examination, dye testing and cystoscopy as appropriate; a positive dye test does not exclude a synchronous ureteral injury, so upper-tract imaging is considered even without specific suspicion (see Vesicovaginal Fistula for the concurrent-injury rate and imaging detail) |
| Vaginal urine leakage with a negative bladder dye test | Ureterovaginal fistula | Upper-tract imaging; CT urography or retrograde/antegrade study when indicated. Absence of flank pain or hydronephrosis does not exclude it. |
| Periurethral defect or leakage associated with voiding | Urethrovaginal fistula | Urethral/vaginal examination and cystourethroscopy; distinguish sphincteric leakage |
| Cyclical hematuria after cesarean delivery | Vesicouterine fistula | Bladder/uterine evaluation and selected imaging |
| Vaginal passage of stool or flatus | Rectovaginal fistula (RVF) | Examine the tract and sphincter; assess inflammatory disease, collections and prior colorectal surgery |
| Leakage after obstructed labor | Obstetric fistula, possibly with urethral or rectal injury | Map all defects, scarring, bladder capacity and continence mechanism; record an appropriate classification |
Urinary Fistula Options
| Situation | Options and limitations |
|---|---|
| Recent small VVF with viable tissue | A finite trial of bladder drainage may be reasonable. Catheter-only closure was 19/239 (8%) in the benign gynecologic-surgery review; the review's pooled 92.9% “conservative” success comes from heterogeneous studies and is not a catheter-only success rate.[4] |
| Selected tiny VVF | Endoscopic fulguration, laser or sealants have small-series evidence. |
| Accessible VVF | Latzko or Sims-Simon, selected for tissue and vaginal anatomy. Preserve viable tissue; wide tract excision is not always needed. |
| Inaccessible VVF or associated ureteral reconstruction | O'Conor or extravesical repair, with interposition when indicated. |
| Recurrent or irradiated VVF | Reassess tissue, capacity and goals; consider vascularized interposition, staged repair or diversion. For radiation-associated repair, the EAU 2026 guideline recommends an interposition graft and advises avoiding irradiated bowel if urinary or fecal diversion is required .[1] |
| Ureterovaginal fistula | Prompt drainage with retrograde/antegrade stenting when feasible; nephrostomy if required. Persistent leakage or obstruction may need ureteral reconstruction. Success depends on timing, injury and selection; see the clinical pathway. |
| Urethrovaginal fistula | Vaginal repair, with urethral reconstruction/interposition as needed. Counsel separately about anatomical closure and residual stress incontinence. |
| Vesicouterine fistula | Selected small recent defects may be observed with drainage; persistent defects need individualized repair, including fertility goals. A 2024 review of 67 mostly case-report or observational publications (284 post-cesarean patients) found that most reported repairs were delayed and used two-layer bladder closure.[7] Robotic-assisted laparoscopic repair with omental interposition was described in three vesicocervical or vesicouterine fistulas that the authors considered inaccessible transvaginally: two followed cesarean delivery complicated by bladder injury, and one followed difficult vaginal birth after a prior cesarean. All three repairs were successful, with no intraoperative or postoperative complications reported during more than 18 months of follow-up.[5] |
| Obstetric fistula | Map urethral involvement, scarring and capacity. Individualize reconstruction and postoperative drainage. For simple obstetric urinary fistula due to obstructed labour (mid-anterior vaginal wall, minimally scarred, no more than 3 cm), WHO recommends 7–10 days of postoperative bladder catheterization as an alternative to longer drainage.[6] The 2026 IUGA–ICS Delphi consensus recommends a minimum of 10–14 days after obstetric urinary fistula repair and a dye test at catheter removal; this expert consensus differs from WHO's trial-informed 7–10-day option for simple obstructed-labor fistulas described above.[3][6] |
| Incontinence after obstetric fistula closure | Confirm closure and characterize stress, urgency and emptying problems. Begin appropriate conservative care, including pelvic floor muscle training for stress incontinence, and select further treatment after assessing the leakage mechanism.[3] |
After VVF repair, maintain continuous bladder drainage until healing is confirmed. EAU expert opinion suggests 10–14 days for simple or postsurgical repairs and 14–21 days for complex or postradiation repairs .[1] The technique pages carry cohort-specific outcomes.[1][3][4]
Rectovaginal Fistula Options
| Situation | Approach |
|---|---|
| Acute obstetric or minimally symptomatic benign RVF | Selected nonoperative care for several months, including wound care and stool regulation; infection or abscess requires treatment. |
| Low RVF with suitable rectal tissue | Endorectal advancement flap; assess whether sphincter repair is also needed. |
| Obstetric/cryptoglandular RVF with sphincter defect | Consider sphincter repair with local closure or episioproctotomy, according to anatomy and continence. |
| Complex/recurrent RVF | Martius or gracilis interposition may be appropriate. ASCRS does not require Martius before gracilis; choose reach, tissue and donor morbidity. |
| Anastomotic RVF | Control sepsis. After failed colorectal anastomosis, the ASCRS 2022 guideline describes initial fecal diversion as the general approach; selected immediate or early postoperative fistulas may instead undergo reoperation and repeat anastomosis. Some fistulas close with diversion alone, while persistent defects may need abdominal reconstruction.[2] |
| Crohn-related RVF | Coordinate gastroenterology and colorectal care: drain sepsis, treat inflammation and select reconstruction when tissue is suitable. “Medical therapy first” must not delay drainage of an abscess. |
| Radiation-associated or otherwise unsalvageable RVF | Consider interposition when feasible, or diversion/proctectomy with or without reconstruction in selected patients. No flap guarantees healing. |
These are ASCRS options based largely on low-quality observational evidence; fecal diversion and operative timing remain individualized.[2] See Principles of Fistula Repair for tissue, drainage and outcome-reporting principles.
Treatment Database
| Technique | Fistula Type | Best for / indication |
|---|---|---|
| Conservative Management | VVF | Selected small, recent VVF with viable tissue; finite bladder-drainage trial and early reassessment. |
| Endoscopic Management | VVF | Selected tiny VVF; fulguration, laser or sealants have limited small-series evidence. |
| Latzko Repair | VVF | Apical post-hysterectomy VVF with adequate vaginal depth — partial colpocleisis. |
| Sims-Simon Closure | VVF | Mid-vaginal / trigonal / apical VVF preserving vaginal length; edge trimming individualized. |
| O'Conor Repair | VVF | High fixed-vault VVF inaccessible transvaginally, or peri-orifice VVF requiring intravesical exposure or ureteral reconstruction. |
| Extravesical Repair | VVF | Selected accessible abdominal VVF — avoids a separate access cystotomy; bladder defect still requires closure. |
| Tissue Interposition Flaps | VVF | Recurrent, radiated, or complex fistulas — Martius, gracilis, omental, or peritoneal flaps. |
| Vesicouterine Fistula Repair | VUF | Selected small recent defects: drainage; persistent fistula: individualized repair and fertility counseling. |
| Ureterovaginal Fistula Repair | UretVF | Early upper-tract drainage when feasible; reconstruction for persistent leakage, obstruction or nonviable ureter. |
| Urethrovaginal Fistula Repair | Urethrovaginal | Transvaginal layered repair; consider Martius for tissue deficit or recurrence and interposition for radiation-associated fistula. Counsel about post-repair stress incontinence. |
| Nonoperative RVF Management | RVF | Obstetric, Crohn's, anastomotic, or palliative RVF — observation, anti-TNF, or diversion. |
| ERAF ± Sphincteroplasty | RVF | Low / mid RVF with healed rectal mucosa; add sphincteroplasty for anterior EAS defect. |
| Episioproctotomy | RVF | Obstetric / cryptoglandular RVF with sphincter defect or cloaca — transperineal division + layered repair. |
| Transvaginal RVF Repair | RVF | Low, non-irradiated, uninflamed RVF — vaginal-side advancement flap or layered closure. |
| Transanal Minimally Invasive Repair | RVF | Selected RVF accessible transanally in experienced centers; outcome evidence is mainly small series. |
| Anal Sphincteroplasty | RVF | Selected sphincter defect with fecal incontinence; compare sphincter repair, neuromodulation and other options. |
| Fecal Diversion | RVF | Selected adjunct or definitive symptom control; closure benefit is uncertain and depends on the clinical setting. |
| Transabdominal RVF Repair | RVF | Selected high or inaccessible, anastomotic, recurrent or radiation-associated RVF; options include separation with interposition, restorative resection, or proctectomy with permanent diversion when reconstruction is unsuitable. |
