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.
