The Management of Iatrogenic Ureterovaginal Fistula in a Resource-Limited Setting: A 12-Year Experience at Four Fistula Surgery Centers in Uganda

Background Ureterovaginal fistulae usually follow iatrogenic injury to the ureter during pelvic surgery. This manifests as urine incontinence and results in serious psychosocial effects on women. Ureterovaginal fistulae unlike vesicovaginal fistulae present challenges in diagnosis and management especially in resource-constrained settings. Objective The objective of this study is to describe the magnitude, etiology, diagnosis, management, and outcomes of iatrogenic ureterovaginal fistula in Uganda over a 12-year period. Methods A retrospective review of charts for women who had fistula repair at four fistula repair centers in Uganda from 2010 to 2021 was conducted. The diagnosis of ureterovaginal fistula was made clinically using a history of leakage of urine through the vagina following a pelvic surgery, a negative methylene blue dye test, and a three-swab test. All women were managed using open transvesical ureteral reimplantation with or without a Boari flap. The outcome of surgery was successful fistula repair with urine continence and was determined at two months post-surgery. Results Overall, 477 women were managed for genitourinary fistulae during the study period. Approximately one in every 10 women with genitourinary fistula had an iatrogenic ureterovaginal fistula (n=47, 9.8%). The mean age of women with ureterovaginal fistula was 31.9 (SD: ±11.8) years. The majority of ureterovaginal fistulae (n=33, 70.7%) followed cesarean sections done at general hospitals (n=22, 46.8%) by medical officers (n=32, 68.1%). Clinical assessment was accurate in diagnosing ureterovaginal fistula. Successful fistula repair was achieved in 45 (95.7%) cases. Conclusion Iatrogenic ureterovaginal fistulae are common in Uganda, and most follow cesarean section performed at lower-level health facilities by medical officers. In resource-limited settings where advanced diagnostic techniques are not available or not affordable, simple stepwise clinical evaluation is effective in making a diagnosis. Open ureteral reimplantation with or without a Boari flap has a high successful repair rate.
