Reproductive prognosis after abdominal metroplasty in bicornuate or septate uterus: a life table analysis.

Reproductive prognosis after abdominal metroplasty was assessed in 73 women with a septate and 71 with a bicornuate uterus who underwent metroplasty at the First Obstetric and Gynecologic Clinic of the University of Milan between 1972 and 1985. The overall cumulative 5-year delivery rates were respectively 70% and 73% in women with septate and bicornuate uterus, rising constantly with time. The number of previous miscarriages did not affect the reproductive prognosis: the 5-year probability of giving birth was 64% and 75% in the women with septate uterus and respectively fewer than two or more previous miscarriages, and the corresponding values were 66% and 73% in the bicornuate uterus subgroup. The miscarriage rate (about 20%) was similar with both types of malformation.
