Uterovaginal canalization and endometrial ablation of the obstructed uterine horn with hypoplastic cervix in the didelphic uterus.

Maldevelopment of the mullerian duct system may result in various urogenital anomalies including didelphic uterus with a hypoplastic cervix. Two women with this anomaly experienced symptoms including recurrent lower abdominal pain off and on of 1 to 2 years' duration. Magnetic resonance imaging revealed a double uterus with right hematometrium both patients. After hysteroscopic identification of hypoplasia of right uterine cervix, laparoscopic resection of the hematosalpinx, followed by uterovaginal canalization and prophylactic endometrial ablation of the right uterus was successfully performed by resectoscope. Normal menstruation ensued during follow-up of 18 and 24 months, respectively. Our experience suggests that uterovaginal canalization with prophylactic endometrial ablation may be an efficacious alternative to hysterectomy for management of didelphic uterus with a hypoplastic cervix.
