Hysteroscopic treatment of the septate uterus.

Twelve patients with symptomatic septate uteri underwent hysteroscopic division of the uterine septum, monitored by concomitant laparoscopy, over a six-year period. The preoperative reproductive performance included 42 pregnancies, with only three viable deliveries. Ten of the 12 patients conceived within one year after therapy, and eight of these patients delivered a live infant at term. Two patients had a spontaneous abortion at six and eight weeks after therapy, respectively, but in each, a subsequent pregnancy was carried to term. Three patients are currently pregnant (eight, 12, and 18 weeks). Two patients have not as yet conceived. Two patients required a second hysteroscopic operation because a partial residual septum was observed on the posttreatment hysterogram.
