Introduction: We aimed to report the outcomes of patients undergoing vesicovaginal fistula (VVF) repair to identify prognostic factors. Materials and Methods: Patients who underwent VVF repair between January 2009 and October 2015 were reviewed. Primary outcome was fistula closure at 3 months. Results: A total of 123 patients and 139 procedures of VVF repair were reviewed. The overall success rate was 85.6%. There were no significant differences in age (p = 0.476), etiology (p = 0.900), fistula duration (p = 0.491) and number of repairs (p = 0.509) between success and fail group. Moderate or severe perifistula fibrosis and multiple fistula were associated with failure in repair of fistula (70.8 vs. 93.4%, p < 0.001; 62.5 vs. 88.6%, p = 0.005). No difference was seen in success rate of vaginal and abdominal approaches (86.0 vs. 85.0%, p = 0.800). Logistic regression analysis identified fistula number (p = 0.003) and perifistula fibrosis (p = 0.002) as 2 independent prognostic factors. Medium/large fistulas were 3.2 times more likely to fail in repair than small fistulas (OR 3.2, 95% CI 0.95-10.6, p = 0.061). Conclusions: Fistula number and perifistula fibrosis were 2 independent prognostic factors for fistula repair. Unsuccessful closure was more likely in medium/large VVF.
