Síndrome de Herlyn-Werner-Wunderlich

Uterus didelphys with obstructed hemivagina frequently associated with ipsilateral renal agenesis is a rare congenital anomaly known as Herlyn-Werner-Wunderlich syndrome (HWW). We report the case of a 31-year-old woman with no relevant medical history, with scant, intermittent and ill-smelling metrorrhagia for the last 2-3 months. Intraoperative vaginal exploration revealed a hypotrophic cervix and the external orifice of a fistula communicating with the right uterine cavity and draining a dark hematic fluid. Intravenous urography showed right renal agenesis and confirmed the suspected diagnosis of HWW.
