Abstract
We report 3 cases of a rare association of uterus didelphys, a unilateral hemivaginal obstruciton and ipsilateral renal agenesis. Case 1 : A newborn girl was suspected of having hydrometrocolpos based on antenatal ultrasonography (USG) findings and she presented with a vaginal cyst after birth. USG demonstrated a double uterus and vagina associated with hemivaginal obstruction and ipsilateral renal agenesis. An incision was made on the vaginal cyst by a vaginal approach immediately after birth. Case 2 : A 12-day-old girl showed a cystic pelvic mass based on antenatal USG findings. It was diagnosed to be an ovarian cyst after birth. The mass was later confirmed to be hydrometrocolpos at the time of operation. A vaginal septectomy was carried out at 6 months of age. Case 3 : A 11-year-old girl was admitted to our hospital due to lower abdominal pain. USG, CT, and MRI showed a hematometrocolposalpinx due to a vaginal obstruction. An excision of the vaginal septum was done through a vaginal approach. The postoperative courses of all cases were uneventful with no recurrences. The relevant Japanese literature was reviewed regarding the symptoms, diagnosis, and associated anomalies in such cases.
