Abstract Background Urogenital fistula can arise from various causes, leading to the development of diverse surgical procedures. The prevention and treatment of obstetric fistula continue to pose challenges in low-income countries. Aim To assess the outcomes and predictors of failure of surgical repair for urogenital fistulas, specifically high vesico-vaginal fistula (VVF) and vesico-uterine fistula (VUF), within our context. Methods Conducted a prospective hospital-based study involving 100 female patients with urogenital fistula (95 VVF and 5 VUF) who underwent abdominal surgical repair at Gezira Hospital for Renal Diseases and Surgery from 2018 to 2023. Collected data encompassing demographics, obstetric history, fistula etiologies, Swab test, cystoscopy findings, urine diversion, ureteric re-implantation, and repair outcomes. Results The majority of women were aged 20–29 years (39%), illiterate (62%), and had a low socio-economic status (87%). Lack of antenatal care was noted in 77% of patients. Fistula etiologies were predominantly obstetric (70%), mainly due to spontaneous vaginal delivery (SVD), with the remaining 30% attributed to gynecological causes (hysterectomy). In terms of fistula characteristics, all patients had a high-level fistula, 95% had a single fistula, and 69% had a posterior wall fistula. Successful closure was achieved in 84% of cases, with 11% experiencing ureteric involvements. The analysis of failures pointed to recurrent fistulae (50%), larger fistula size (31%), and the presence of multiple fistulae (19%) as notable predictors of unsuccessful repair. Conclusion VVF was the prevalent type of urogenital fistula in our population. Risk factors included being in the third decade of life, illiteracy, low socioeconomic status, and a lack of prenatal care. Obstetric causes, particularly prolonged and obstructed labor through SVD, dominated the etiology. Surgical procedures resulted in successful closure in 84% of cases. Recurrent fistulae, larger size, and multiple occurrences emerged as predictors of surgical repair failure.
