Double uterus, hemivagina and renal agenesis is a rare congenital urogenital anomaly characterized by the presence of double uterus (didelphys, bicornuate or septum-complete or partial), unilateral cervico-vaginal obstruction (obstructed hemivagina-communicant, not communicant or septate and unilateral cervical atresia) and ipsilateral renal anomalies (renal agenesis and/or other urinary tract anomalies). Patients are usually diagnosed at puberty after menarche due to recurrent severe dysmenorrhea, chronic pelvic pain, excessive foul smelling mucopurulent discharge, spotting and intermenstrual bleeding (depending on the existence of uterine or vaginal communications). fever, dyspareunia, and a palpable abdominal, pelvic or vaginal mass (mucocolpos or pyocolpos) may also be present. The disease is double uterus-hemivagina-renal agenesis syndrome (Monarch Disease Ontology term MONDO_0008636). Also known as: Double uterus and obstructed hemivagina syndrome, Herlyn-Werner syndrome, OHVIRA syndrome, Wunderlich syndrome, obstructed hemivagina and ipsilateral renal anomaly.
