Ureterovaginal Fistula: A Report of 12 Cases and Review of the Literature

Ureterovaginal fistula is an uncommon complication of pelvic operations, seen most often after Wertheim's hysterectomy. We report 12 cases of ureterovaginal fistulas seen during a 20-year period, all of which followed operations for benign gynecologic conditions. Most patients had no urinary symptoms until the sudden onset of incontinence 1 to 4 weeks postoperatively. Diagnosis was established readily by a combination of excretory urography, cystography, cystoscopy, retrograde pyeloureterography and dye studies. In our series only 1 patient was treated by primary nephrectomy, while 11 underwent ureteroneocystostomy: 2 with a Boari flap and 9 by a direct method. Reconstruction failed in 2 patients, 1 of whom required a secondary nephrectomy.
