| Foley Catheter Drainage (VVF) | VVF | Conservative management for **small (< 5 mm), fresh, simple, non-irradiated** VVF. Continuous Foley × 2–6 weeks may permit spontaneous closure in a minority of carefully selected cases. Often combined with antibiotics and topical estrogen. |
| Endoscopic Fulguration (VVF) | VVF | Cystoscopic Bugbee-electrode fulguration of the epithelialized fistula tract + 2–3 wk Foley drainage. **73–80% success** for very small fistulas (≤ 3.5–7 mm). Day-care procedure — also useful for small residual fistulas after failed open repair. |
| Transvaginal Latzko Repair | VVF | **Partial colpocleisis** — vaginal epithelium denuded around the fistula without excising the tract; multi-layer imbrication of surrounding fibromuscular tissue. **95–100% success** in non-irradiated post-hysterectomy VVF. Highly versatile — applicable to vault fistulas, complex fistulas, and postpartum settings. |
| Transvaginal Sims-Simon Multi-Layered Closure | VVF | Circumferential incision of vaginal epithelium around the fistula, wide vesicovaginal mobilization, layered bladder closure (mucosa ± muscularis / detrusor), then vaginal-wall closure. Edge-excision (freshening) remains debated. Modified Sims-Simon: **100% success in 47 consecutive cases without interposition, median OR 40 min** (recent series). |
| Transvaginal VVF Repair with Martius Flap | VVF | Transvaginal closure with interposed [Martius labial fat-pad flap](/docs/foundations/surgical-principles/flaps/martius) for recurrent, radiated, or complex VVFs where tissue bulk and vascularity drive the decision. Kapriniotis 2024 review: routine use **probably unnecessary for simple non-irradiated fistulas** (> 90% closure without flap) but valuable in 80–97% of complex cases. |
| Open / Robotic O'Conor VVF Repair | VVF | Transabdominal bivalve of the bladder through the fistula, excision of fistula tract, and layered closure with omental interposition. **EAU Robotic Urology Section consensus** recommends robotic O'Conor for supratrigonal, non-obstetric VVF (Randazzo 2020). Robotic series: **91–100% success** at median console 187 min, EBL 50 mL, LOS 1 day. |
| Laparoscopic VVF Repair | VVF | Laparoscopic transvesical or extravesical approach. Singh 2026 25-yr single-center experience: **96.6% first-repair success** with laparoscopic — comparable to open (94.0%) and transvaginal (94.2%). |
| Extravesical Transabdominal VVF Repair | VVF | Dissection of the vesicovaginal space without cystotomy. Less invasive, minimizes bladder tissue loss. Increasingly used with laparoscopic / robotic assistance as an alternative to the transvesical O'Conor approach. |
| Omental Flap Interposition (VVF) | VVF | Pedicled [omental flap](/docs/foundations/surgical-principles/flaps/omental) — most common abdominal interposition. Used for large fistulas, radiation, and complex transabdominal repairs. Minor risks: postoperative pain, ileus. |
| Gracilis Muscle Flap (VVF) | VVF | [Gracilis transposition](/docs/foundations/surgical-principles/flaps/gracilis) for VVFs with significant tissue loss or radiation. Donor-site morbidity; technically demanding. More commonly used for RVF and RUF in male patients. |
| Peritoneal Flap Interposition | VVF | [Peritoneal flap](/docs/foundations/surgical-principles/flaps/peritoneal) as an alternative to omentum during transabdominal / laparoscopic / robotic repair. Less robust blood supply but readily available without additional dissection. |
| Rectus Abdominis Flap (Radiation VVF) | VVF | Pedicled rectus abdominis flap based on the deep inferior epigastric vessels. Provides non-irradiated, well-vascularized tissue for radiation-induced recurrent VVF. **100% success in small series at 5–8 yr follow-up.** |
| Small Intestinal Graft (Salvage Radiation VVF) | VVF | Salvage technique for recurrent radiation VVF after multiple failed repairs. Complex; last resort before urinary diversion (Vaso 2015 case report). |
| Foley Drainage ± Hormonal Suppression (VUF) | VUF | Conservative management for **small (< 5 mm), early-diagnosis** VUF. Continuous Foley drainage; some series add GnRH-agonist hormonal suppression to halt menstrual flow during healing. Limited evidence; case reports. |
| Uterine-Sparing Robotic O'Conor (VUF) | VUF | Modified O'Conor for vesicouterine fistula (Youssef syndrome) preserving the uterus when fertility is desired. Intracorporeal access to the vesicouterine pouch with hysterotomy-side closure. Bonavina 2024 SR (n = 284): **100% success on first attempt** across all surgical approaches. |
| Hysterectomy with Bladder Repair (VUF) | VUF | Definitive VUF repair for patients not desiring uterine preservation — hysterectomy + multilayer bladder closure with omental interposition. Hysterectomy is **not routinely necessary** — uterine-sparing repair feasible with 23 reported live births post-repair (Bonavina 2024). |
| Transvaginal VUF Repair | VUF | Layered transvaginal repair in prone jackknife position. Feasible and effective in experienced urogynecologists' hands; 2–3.5 yr durability reported. |
| Ureteral Stent (UretVF) — First-Line | UretVF | **AUA Urotrauma 2020 first-line** for ureterovaginal fistula. Retrograde JJ stent attempted first; if retrograde fails, antegrade percutaneous nephrostomy + antegrade stent. Stent × 6 wk; **64–100% success**. Rabani 2021 — retrograde stent successful in 6/8 (75%) post-cesarean UretVF; all resolved at 3 mo with no stricture. |
| Ureteroneocystostomy ± Psoas Hitch (UretVF) | UretVF | Definitive [reimplantation](/docs/surgical-techniques/04d-upper-tract-reconstruction/ureteral-reimplantation) when stent fails. Open / laparoscopic / robotic; extravesical (Lich-Gregoir) most common for MIS. Linder 2018 robotic series: **100% success at 29.3 mo**. Kidd 2021 multi-institutional: 100% success, 1-day LOS. |
| Boari Flap (UretVF) | UretVF | [Boari tubularized bladder flap](/docs/surgical-techniques/04d-upper-tract-reconstruction/boari-flap-psoas-hitch) for distal ureteral defects too long for direct reimplantation + psoas hitch. Bridges defects up to 8–12 cm. Avoid in radiated bladder. |
| Ureteroureterostomy (UretVF) | UretVF | End-to-end ureteral anastomosis for mid-ureteral UretVF with adequate proximal and distal length. Performed in 17% of robotic UretVF repairs (Kidd 2021). |
| Transureteroureterostomy (UretVF) | UretVF | Anastomosis of injured ureter to contralateral healthy ureter. Reserved for cases where ipsilateral reconstruction is not feasible. Avoid if contralateral disease, stones, or urothelial carcinoma. |
| Transvaginal Layered UVF Repair | Urethrovaginal | Excision of fistula tract + multi-layer tension-free closure of urethra + separate vaginal-wall closure. Preferred approach. **90–100% primary success**; up to **52% develop post-repair SUI** due to sphincteric damage — counsel patients re: staged anti-incontinence procedure (synthetic / autologous sling cures 59% / improves 32%). |
| Latzko + Martius Flap (UVF) | Urethrovaginal | Latzko technique with [Martius bulbocavernosus flap](/docs/foundations/surgical-principles/flaps/martius) interposition for mid-urethral fistulas where periurethral tissue is scarce. Provides well-vascularized tissue to reinforce the repair (Zilberlicht 2016). |
| Labial Pedicle Flap Urethroplasty (Complex UVF) | Urethrovaginal | Labial skin flap reconstruction of the urethra + simultaneous fistula closure for complex UVF associated with urethral stricture. Xu 2013 series (n = 44): **93% anatomical / 91% functional success**. |
| Nonoperative Management (Obstetric RVF) | RVF | Sitz baths, fiber, wound care, antibiotics for infection, stool-bulking × 3–6 months. **52–66% healing** for obstetric RVF (ASCRS 2022 Recommendation 12 Grade 2C). May also be considered for other benign minimally symptomatic fistulas. |
| Draining Seton (RVF) | RVF | Facilitates resolution of acute inflammation / infection; useful for narrow fistulas, small vaginal openings, or multiple tracts. Long-term symptomatic relief for poor surgical candidates (ASCRS 2022 Recommendation 13 Grade 1C). |
| Medical Therapy for Crohn's RVF | RVF | [Infliximab](/docs/foundations/pharmacology/legacy-low-evidence) ± immunomodulator + antibiotics + seton for drainage. **ACG 2025 Strong Recommendation, Moderate Evidence**. ACCENT II trial — efficacy for RVF closure maintenance. Surgical repair only after endoscopic mucosal healing of the rectosigmoid is confirmed. |
| Endorectal Advancement Flap (ERAF) | RVF | **ASCRS 2022 procedure of choice** (Recommendation 14 Grade 1C). Full-thickness or partial-thickness rectal flap advanced over the fistula opening. **41–78% success** depending on etiology / technique. Failure factors: sphincter abnormalities, Crohn's, prior radiation, recurrent fistula. |
| ERAF + Sphincteroplasty | RVF | ERAF combined with overlapping anal sphincteroplasty ± levatorplasty when sphincter defect is present. **Improves healing to 80%** vs ERAF alone (41%). |
| Episioproctotomy | RVF | Transperineal division of anterior anal sphincter complex + rectovaginal septum, then layered repair. **78–100% healing**; postoperative fecal incontinence rare (~8%). ASCRS 2022 Recommendation 15 Grade 1C — for **obstetric or cryptoglandular RVF with sphincter defects**. |
| Transvaginal RVF Repair | RVF | Vaginal advancement flap or layered closure from the vaginal side. Used in 17% of procedures in large series; preferred by some urogynecologists. Best for low, non-irradiated, uninflamed RVF. |
| Martius Flap Interposition (RVF) | RVF | **First-line interposition** per ASCRS 2022 Recommendation 16. **65–94% per-procedure / 69% per-patient success at 23 mo** (Pastier 2024 — equivalent to gracilis with shorter LOS, similar morbidity, **option to avoid stoma** in 27% with no impact on outcome). Smoking is the only negative predictor. |
| Gracilis Muscle Interposition (RVF — Salvage) | RVF | Reserve as **salvage after Martius failure** (Pastier 2024). Pooled 64% success (range 33–100%); 59% in reoperative series. Longer LOS, higher complication rate (28–47%), 32% donor-site SSI; stoma formation associated with improved outcomes. |
| Fecal Diversion Alone (RVF) | RVF | Diverting loop ileostomy or colostomy. **37% heal with diversion alone** in anastomotic RVF series. Used when active inflammation or sepsis precludes definitive repair, or as a temporizing measure. |
| Repeat Coloanal Anastomosis / Pull-Through (GRECCAR) | RVF | Transabdominal redo coloanal anastomosis ± delayed colonic pull-through for **anastomotic RVF post-colorectal surgery** (ASCRS 2022 Recommendation 17 Grade 1C). Major procedures (gracilis, coloanal, APR) — independently associated with success (OR 6.4; Corte 2015). |
| Abdominoperineal Resection (APR — RVF) | RVF | Last resort for intractable RVF disease — typically radiation-induced or refractory Crohn's. Permanent colostomy. Reserve for failed all-other-options scenarios. |
| Obstetric VVF Repair (Goh / Waaldijk Classification) | Obstetric | Classification-driven transvaginal repair of obstructed-labour-injury-complex fistulas. **Goh classification preferred** (uses fixed external-meatus reference; superior prognostic accuracy vs Waaldijk; predicts post-closure incontinence). Fistula Foundation **87% success across 24,568 repairs**; Mourad 2026 16-yr multinational (n = 1,185, 12 countries) — 82% closure; primary 85% / simple 91%. |
| Panzi Score (Complex Obstetric Severity) | Obstetric | Composite 0–3 score (Mukwege 2018) derived from Goh + Waaldijk: circumferential defect + proximity to urethra + size. **Each 1-point increase → 1.65× failure odds** (p < 0.001). Parsimonious operative-decision aid for circumferential / extensive injury. |
| POFRI Procedure (FIGO 2025) | Obstetric | **Post-Obstetric-Fistula Residual-Incontinence (POFRI)** procedure per FIGO 2025 expert opinion. For patients with closed fistulas but **persistent SUI (16–55%)** after successful closure. Most have stress-predominant urodynamics (67% SUI, 47% urge, 47% mixed; Nardos 2022). |
| Adjuncts (PRP / SIS / Buccal Graft) | Obstetric | Adjunctive therapies for complex circumferential or recurrent obstetric fistulas: platelet-rich plasma, small intestinal submucosa, and buccal mucosal grafts. Emerging data; reserve for cases with extensive tissue loss after multiple failed repairs. |
