Uterus didelphis with obstructed hemivagina and ipsilateral renal agenesis: ultrasound and magnetic resonance imaging diagnosis.

The association of uterus with unilateral imperforate hemivagina and ipsilateral renal agenesis is extremely rare. We present a case of a 13-year-old virginal patient in whom a combination of intravenous pyelogram and ultrasound was comparable to magnetic resonance imaging in permitting an accurate preoperative diagnosis thus allowing for early and appropriate surgical intervention and possible preservation of fertility.
