Recent Trends and Characteristics of Genitourinary Fistulas in Rwanda

ABSTRACT

INTRODUCTION AND OBJECTIVE: Genitourinary fistulas (GU) in Rwanda have significantly increased in recent years. We previously reported an increase in the proportion of vesicouterine, vesicocervical and uterovaginal fistulas, with the majority occurring after Cesarean section. Our goal is to examine the characteristics of our the most recent cohort. METHOD(S) A cross-sectional study was conducted of women presenting for evaluation to the International Organization for Women and Development (IWOD) in Kigali, Rwanda, from 2018 to 2019, and 2022. No data was collected during years 2020 and 2021, due to the COVID-19 pandemic. Data was collected from medical records and included region of residence, surgical history, presence of fistula, and type. RESULT(S) A total of 434 women were evaluated, of these 194 (44.7%) were diagnosed with GU fistula. In 2018, fistula types were 40 (52%) vesicovaginal, 5 (6%) urethral, 5 (6%) ureterovaginal, 23 (30%) vesicoureterine or vesicocervical, and 7 (9%) juxtacervical. In 2019, the fistula types were 26 (41%) vesicovaginal, 4 (6%) urethral, 6 (10%) ureterovaginal, 17 (27%) vesicoureterine or vesicocervical, and 10 (16%) juxtacervical. In 2022, the fistula types were 33 (61%) vesicovaginal, no urethral fistula reported, 7 (13%) ureterovaginal, 8 (15%) vesicoureterine or vesicocervical, and 6 (11%) juxtacervical. CONCLUSION(S) In comparison to our prior cohort, recent data shows a stable proportion of types of fistulas. The increased number of vesicouterine, vesicocervical, and juxtacervical fistula may be higher due to increased performance of Cesarean sections.
