    Abstract:
    OBJECTIVE: We describe the management and outcomes of ureterovaginal fistulas over a 13-year period and present a treatment algorithm. METHODS: We performed a review of ureterovaginal fistula cases between January 2005 and December 2017 at our tertiary academic center. Demographics, diagnostic approaches, and treatment outcomes were assessed. RESULTS: Nineteen cases of ureterovaginal fistula were identified. Fistulas developed after hysterectomy in 18 cases and cesarean delivery in 1 case. Our primary treatment was conservative management with ureteral stenting in 12 and reimplantation in 6 cases. There was 1 case of spontaneous resolution. Ureteral stenting was successful in 11 (92%) of 12 patients. Stents were left in place for an average of 66 days (27-92 days). Complications of stents included pyelonephritis in 2 cases (18%) and stricture in 1 case (9%). Ultimately, conservative management was successful in treating ureterovaginal fistulas in 10 (83%) of 12 cases. The indications for primary ureteral reimplantation were concurrent vesicovaginal fistula in 3 cases, history of ureteral injury with surgical repair during the index surgery in 2 cases, and a 1-year delay in diagnosis in 1 case. A variety of follow-up surveillance methods were used, including tampon tests, computed tomographic urograms, retrograde pyelograms, and MAG-3 Lasix renal scans. CONCLUSIONS: In carefully selected patients, ureteral stenting results in high cure rates for posthysterectomy ureterovaginal fistulas and should be considered first-line therapy. Complicated ureterovaginal fistulas may be best managed by primary ureteral reimplantation.
