Repair of vesicovaginal fistula: Single-centre experience and analysis of outcome predictors

Objectives: Data from 80 patients with a vesicovaginal fistula (VVF) were collected and analysed, to define the probable factors affecting the outcome of surgery.

Patients and methods: In a retrospective study, the records of 80 women with a mean (SD) age of 35.8 (9) year were assessed; 40% of the VVF occurred after abdominal hysterectomy, 30% after Caesarean section, 15% after difficult vaginal delivery and 11.25% after forceps vaginal delivery. Fifteen women (18%) had a previous failed repair. The median duration of the VVF was 11.5 months.

Results: Of the 80 VVF, 41 were high, 30 were low, four combined high and low and five were at the bladder neck. Nine cases had multiple openings on pan-endoscopy. An abdominal approach was used in 54 patients, vaginal in 20 and a combined approach in six. The median (SD) catheter duration was 14 (3.9) days. Ureteric stents were left in 59 patients. At a mean (SD) follow-up of 33.02 (65.7) months, the VVF was cured in 65 (81%) patients. Univariate analysis of variables possibly affecting the success of surgery showed that the duration of VVF, surgical approach, previous repair and position of the VVF were significant factors. Only previous intervention and surgical approach maintained significance in multivariate analysis.

Conclusion: An abdominal approach seems to give superior results. Previous failed repair had a significant negative effect on success. An earlier repair (<6 months) is associated with higher success rates.
