A total of 182 women with uterine anomalies were observed over a period of 18 years. In all, 126 women had 265 pregnancies, fetal survival rate was 66%, perinatal mortality 8% and premature labors occurred in 23%. When the uterine anomalies were grouped according to degree of failure of normal and uterine development, the complete septate uteri had the best fetal survival rate (86%), complete bicornuate uteri (50%) and unicornuate (40%) poorest. Cervical cerclage was applied most in the partial bicornuate uteri (17%), where fetal survival in operated cases was: before operation, 53% and after, 100%. The frequency of breech presentation was 40-50% in all groups except complete septate uteri (25%) and complete bicornuate (0%). The highest cesarean section rate (82%) was in deliveries of patients with uterus didelphys. The frequency of cesarean section among total deliveries was 53%. Metroplasty was carried out on 19 patients. The obstetric outcome improved from 10% successful pregnancies before surgery to 88% postoperatively.
