Reproductive performance after the repair of obstetric vesico-vaginal fistulae.

Between 1966 and 1976, 148 out of 162 patients with obstetrically acquired vesico-vaginal fistulae were successfully repaired in Lagos University Teaching Hospital. The reproductive performance of these patients after repair has been reviewed with special regard to menstruation, satisfactory coitus and childbearing. Before the repair of the fistulae 66 patients (40.6%) had secondary amenorrhoea ranging from 4 months to 15 years. There were 3 cases each of oligomenorrhoea and cryptomenorrhoea. After repair menstruation returned within 6 months in 58 patients. Secondary amenorrhoea is thought to be due to a combination of severe malnutrition, anaemia, endometritis, psychological upsets and occasionally endocrine malfunction due to focal anterior pituitary necrosis. Repair of the fistulae worsened gynatresia in 17 cases. Twelve patients had dyspareunia and 3 others had apareunia. Thirty-one patients achieved 38 pregnancies after repair. Thirty-two infants were delivered by lower segment Caesarean section. There were 5 vaginal deliveries and one abortion. The average birth weight was 2.96 kg. The corrected perinatal mortality was nil. Five cases had a recurrence of the fistulae after delivery and 2 others had stress incontinence. Electric lower segment Caesarean section is the ideal method of delivery.
