Characteristics of Obstetric and Iatrogenic Urogenital Fistulas in Burkina Faso: A Cross-Sectional Study.

Objective: To compare the sociodemographic, clinical, and therapeutic characteristics of obstetric urogenital fistulas (OF) and iatrogenic urogenital fistulas (IF) treated in seven centers in Burkina Faso. Material and Methods. We carried out a cross-sectional study over a seven years' period (January 1, 2010 to December 31, 2016). We considered as iatrogenic all urogenital fistulas (UGF) occurred after elective caesarean section, gynecologic surgery (hysterectomy, myomectomy, and prolapse repair), or induced abortion. UGF following vaginal delivery after prolonged labor without obstetric maneuvers or caesarean section were considered as obstetric. UGF caused by other mechanisms (emergency caesarian section, congenital, and traumatic) were excluded from this study. The statistical analysis was carried out using version 14 of the STATA software. A logistic regression model was used to compare the two groups.

Results: 310 cases of UGF were included. IF accounted for 25.8% (n = 80) versus 74.2% (n = 230) for OF. The median age was 35 years for IF and 35.38 years for OF. The vesicovaginal fistulas were predominant (74.5%) in the two groups. All circumferential fistulas were found in the OF group. OF were frequently associated with residence in rural areas (OR = 1.8; CI = [1.05-3.1]), low level of education (OR = 5.4; CI = [2.3-12.9]), and a height under 158 cm (OR = 3.4 CI = [1.7-6.6]). Vaginal sclerosis was less common among IF (OR = 2.2; CI = [1-4.6]). The failure of surgical treatment after 3 months was more associated with OF (OR = 4.7; CI = [1.1-20.5]).

Conclusion: OF were the most common, frequently affecting short women living in rural area and with low level of schooling. Fistulas were also more severe in the OF group. IF gave better results after surgical repair.
