Pregnancy outcome in women with müllerian duct anomalies

The outcomes of 186 pregnancies in 150 women with müllerian duct anomalies who delivered over an eight-year period were analyzed. The average birth weight was 2,919 g. Eighty-three percent of the deliveries were by cesarean section; malpresentation was the indication for 80% of those deliveries. The incidences of breech presentation and transverse lie were 61% and 11%, respectively. Delivery of preterm infants occurred in 25% of the pregnancies, and 12% were small for their gestational age. There were two sets of twins. A history of a previous preterm infant, recurrent abortion or a second-trimester loss was given by 13%, 9% and 59% of the patients, respectively. Of patients examined for renal anomalies, 11% had a defect, usually unilateral renal agenesis.
