Ultrasound surveillance of pregnancies after metroplasty for septate uterus.

Metroplasties were performed on twenty three septate uterus associated with recurrent reproductive wastage (19 cases) or primary infertility (4 cases). The surgical procedure and ultrasound monitoring of pregnancies conceived postoperatively are reported. Eighteen pregnancies occurred in sixteen patients; fourteen ended in live birth and four spontaneous abortions, including two blighted ova and one mole occurred. It appears from the results that uterine anomalies are rarely the sole cause of primary infertility; therefore, selection of patients is emphasized.
