Abstract
The septate uterus which is induced from congenital müllerian abnormalities, may sometimes result in recurrent abortion, premature labor or infertility. The infertile patient who had a septate uterus, was treated by hysteroscopic metroplasty using YAG laser with laparoscopic guidance under the general anesthesia. There was no significant complications during intraoperative nor postoperative period. Hysteroscopic YAG laser surgery is able to avoid abdominal and uterine wall incision and perform the operation without bleeding compared with transabdominal metroplasty. If the excellent pregnancy rate is recognized, hysteroscopic YAG laser surgery should become the effective operation technique for the septate uterus.
