Congenital absence of the uterine cervix.

Surgical correction of congenital atresia of the uterine cervix by creation of a fistulous communication between the functioning endometrial cavity and the vagina with the use of the atretic cervix as a conduit has been performed in two patients. This technique, which permits egress of menstrual blood and the retention of the capacity to reproduce, should replace hysterectomy as the treatment of choice for this extremely unusual and formerly hopeless Müllerian duct anomaly.
