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 vs. transabdominal vs. combined), timing (immediate vs. early vs. delayed), interposition flap need (none vs. Martius vs. gracilis vs. omentum), and whether a protective diversion is required.
Decision Framework
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 |
| 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 |
A presentation suggests a tract but does not replace anatomical confirmation.[1][2][3]
Urinary Fistula Options
| Situation | Options and key 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; its 92.9% heterogeneous “conservative” figure is not a Foley success rate.[4] |
| Selected tiny VVF | Endoscopic fulguration, laser or sealants have small-series evidence. They are not a required step before repair, and their case-series size limits are not validated universal thresholds. |
| 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. A selected radiation series does not predict an individual patient's success or need for diversion. |
| 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. Case reports do not establish universal hormonal therapy or 100% surgical success. |
| Obstetric fistula | Map urethral involvement, scarring and capacity. Individualize reconstruction and postoperative drainage; WHO's 7–10-day simple-repair recommendation differs from newer expert recommendations favoring longer drainage. |
| Incontinence after obstetric fistula closure | Confirm closure and characterize stress, urgency and emptying problems. Begin appropriate conservative care; select further treatment after assessment. There is no evidence-based requirement for bulking followed by a sling, or for routine PRP/SIS use.[3] |
The technique pages carry cohort-specific outcomes. Raw success percentages from unlike groups should not rank the procedures.[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 and consider diversion; selected patients close with diversion alone, while many need abdominal reconstruction. |
| 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 — workhorse vaginal repair; edge trimming individualized. |
| O'Conor Repair | VVF | Supratrigonal, high, or peri-orifice VVF requiring intravesical exposure ± ureteral reimplantation. |
| 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; add Martius for deficit, recurrence, or radiation. Counsel re: post-repair SUI. |
| 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 | Complex / high / recurrent / radiation / anastomotic RVF — resection + coloanal, DCAA, or APR. |
