Endoscopic Management of Vesicovaginal Fistula
Endoscopic management of vesicovaginal fistula (VVF) covers a spectrum of minimally invasive, endoscopy-guided techniques — from purely cystoscopic interventions (fulguration, laser ablation, tissue-adhesive injection) for small fistulae to advanced laparoendoscopic and transvesicoscopic suture repairs for more complex cases.[1][2]
For the underlying clinical evaluation, classification, and decision algorithm, see the vesicovaginal fistula clinical page. For repair-route selection across the female-fistula spectrum, see the Female Fistula Repair atlas.
Cystoscopy in Diagnosis and Preoperative Planning
Cystoscopy is the cornerstone of VVF evaluation: direct visualization of the bladder-side fistula orifice; assessment of size, location relative to the ureteral orifices and trigone; and evaluation of surrounding-tissue quality. A combined vaginoscopy-cystoscopy technique with simultaneous dual-image (picture-in-picture) display has been described to improve fistula identification and surgical planning in diagnostically challenging cases.[1] The EAU Robotic Urology Section consensus recommends preoperative cystoscopic marking of the fistula with a guidewire or ureteral catheter to guide subsequent repair.[2]
Endoscopic Fulguration (Electrocoagulation)
A purely endoscopic option reported in selected small VVFs; the best-known series included defects ≤3.5 mm, a study selection limit rather than a validated universal cutoff.[3]
Technique
- Cystoscopic insertion of a Bugbee electrode into the fistula tract.
- Electrocoagulation of the epithelial lining.
- Continuous Foley drainage 2–3 weeks postoperatively.
- Anticholinergics to suppress detrusor contraction during healing.
Outcomes
- Stovsky series (n = 15, all fistulae ≤3.5 mm): 75% primary-treatment success (9/12) and 2/3 after failed open repair; 11/15 (73%) overall.[3]
- A five-patient series of defects less than 7 mm reported closure in 4/5; its small uncontrolled sample does not establish a reliable treatment effect.[4]
Best suited as initial treatment for selected very-small fistulae, and as a salvage for small residual fistulae after failed surgical repair.[3]
Laser Ablation / Laser Welding
| Modality | Setting | Outcome |
|---|---|---|
| Laser welding: one Nd:YAG, seven holmium:YAG cases | Single-center n = 8, mean fistula 3 mm (range 2–4 mm) | 7/8 dry after catheter removal; mean follow-up 47 months (range 2–110). One procedure was abandoned for bleeding.[5] |
| Holmium ablation + concurrent vaginal repair | Single case report | Cystoscopic laser ablates the bladder-side opening while transvaginal excision addresses the vaginal side.[6] |
| Laser dissection + pneumovesical laparoscopic closure | Single case after colpectomy in a transmasculine patient | Demonstrated feasibility in that anatomy; comparative tissue-injury or efficacy advantages have not been established.[7] |
These small reports support feasibility in selected cases, not established safety or effectiveness for every fistula ≤4 mm.[5]
Tissue Adhesive Injection (Fibrin Glue / Cyanoacrylate / PRP)
| Approach | Outcome |
|---|---|
| Retrograde endoscopic fibrin glue | 6/8 successes in a mixed urinary-pathology series: seven fistulas of different types (only two VVF) and one caliceal diverticulum. This is not a VVF-specific 75% success rate.[8] |
| Tissue-adhesive review (84 women; 81 VVF) | Fourteen heterogeneous reports, summarized narratively: 12/84 failures/recurrences. Mean follow-up was about 11.5 months; no controlled comparison established superiority of a sealant. Reported complications included septic pelvic thrombosis.[9] |
| Autologous PRP injection + platelet-rich-fibrin glue interposition | Cystoscopic de-epithelialization of the fistula edges, peri-fistula PRP injection, fibrin glue in the tract. 91.7% (11/12) clinical cure at 6 mo.[10] |
Sealants and platelet products remain selectively used options with limited evidence. The review included defects of 0.1–3.9 cm; it does not validate a universal 1-cm threshold or establish the preferred treatment for patients at high operative risk.
Transurethral NOTES
A transurethral endoscopic suture repair using barbed suture has been described for VVFs after hysterectomy for morbidly adherent placenta. In 3 patients, 2 achieved complete resolution; the third had reduction in fistula size and required subsequent laparotomy. This three-case report establishes feasibility only; it does not establish a preferred initial approach.[11]
Transvesicoscopic Repair
Direct placement of laparoscopic ports into the bladder (vesicoscopy) for intravesical visualization and repair:
- Combined vaginal + vesicoscopic repair for complex VVF (n = 9): 89% success at median 30 mo. The approach supplements the vaginal route for fistulae not suitable for pure vaginal repair, and pairs the laparoscopic urologist with the vaginal surgeon.[12]
- Robot-assisted transvesical repair via mini cystotomy has been described, particularly when prior surgical planes have been used in failed repairs.[13]
V-NOTES (Vaginal Natural Orifice Transluminal Endoscopic Surgery)
For apical VVFs, V-NOTES provides endoscopic visualization through the vaginal route. In a 17-patient modified-technique series, 88.2% success (15/17), with both failures cured on second repair. Mean OR 104 min, EBL 10.5 mL, mean LOS 3.3 d.[14] See vNOTES & Robotic vNOTES for the broader platform context.
Laparoscopic and Robotic-Assisted Endoscopic Repair
Not purely "cystoscopic" but the most widely adopted endoscopic approaches:
- Reported 80–100% closure across selected laparoscopic and robotic series; no randomized comparison establishes equivalence to open repair.[15][16]
- The 2015 review reported 95.9% transvesical and 98.0% extravesical closure across heterogeneous reports, almost entirely case reports/series. These are not randomized comparative rates.[15]
- LESS (laparoendoscopic single-site surgery) has feasibility reports, including five VVF cases and a mixed GU-fistula cohort. The reported shorter stay/analgesic use does not establish comparative superiority.[17][18]
- In a 78-patient retrospective abdominal-repair cohort, minimally invasive groups had shorter operations and less blood loss. Prior repair history and timing differed by group; approach was not an independent closure predictor. This is an association within selected groups.[16]
Patient Selection and Limits of the Evidence
Select the intervention using defect size, tissue quality, ureteral proximity, access, prior radiation/repair and patient goals. Case-series cutoffs do not establish a universal algorithm. A predictor measured after abdominal surgical repair should not be transferred to tiny fistulas treated with fulguration or laser.[2][3][5][16]
The 2026 Cochrane item cited below is a protocol for a future review, not completed comparative evidence. Much of the existing endoscopic literature consists of uncontrolled case reports or small series, so an absence of reported complications or a high closure percentage should not be called established safety or equivalence.[19][20]
Common Principles Across Endoscopic Approaches
For reconstructive suture repairs, the common goals are:[2][20]
- Tension-free, watertight closure.
- Well-vascularized tissue.
- Adequate mobilization.
- Protection of the ureteral orifices.
- Postoperative drainage tailored to the repair and tissue. The ERUS robotic consensus suggested about ten days; small endoscopic series often used two to three weeks. See source-specific drainage guidance.
- Plan the first attempt carefully and refer when the necessary reconstructive expertise is unavailable; prior failure prompts reassessment rather than an automatic procedure sequence.
