Uterus didelphys associated with unilateral imperforate vagina.

Two cases of uterus didelphys associated with unilateral imperforate vagina are reported with a review of the literature. In all cases investigated, ipsilateral renal agenesis was found on the affected side. A summary of the embryologic development of the female reproductive tract is included, as well as a possible explanation for this rare anomaly. The authors describe their proposed method of management to achieve freedom from symptoms and maintenance of a relatively intact reproductive tract.
