Objective:To investigate the localization and aetiological factors associated with urinary fistulae at the University Teaching Hospital in Benin-City, Nigeria. Methods: Records on 96 patients treated by the authors at the gynaecological ward of the University of Benin Teaching Hospital, Benin-City, Nigeria between January 1997 and December 2006 were analyzed. Information extracted and analyzed included data on socio-biological, demographic, and obstetric event of the antecedent pregnancy. Results: The average age of patients with vesico-vaginal fistula(VVF) was 34 years with a mean parity of 3. The various mean values for patients’ height, weight and body mass index (BMI) were 1.58m, 58.29kg and 24.13 respectively. The majority (92.7%) of fistulas are obstetric in origin. While 5.21% were due to total abdominal hysterectomy and 2.08% due to post irradiation for advanced gynecological malignancy. 53(55.21%) patients had obstetric operative interventions (Forceps or vacuum extraction, and or caesarean section). Caesarean section contributed 23.96% to the total figure. Juxta-cervical fistula was the most frequent, next mid vagina and followed by vesico-uterine (32. 98%, 24.4% and 19.15% respectively).Conclusion: Obstetric surgical intervention by care providers is a major cause of VVF formation with particular reference to Caesarean section. Vesico-uterine fistulas are on the increase.
