Remnant ureter abscess linked to obstructed hemivagina and ipsilateral renal anomaly syndrome.

Patients with obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome sometimes present with distinct symptoms related to coexisting urogenital abnormalities. We present a case of refractory abscess formation in a blind-ended remnant ureter associated with ipsilateral renal agenesis. A 15-year-old patient with OHVIRA syndrome, who had a blind-ended remnant ureter, underwent obstructed hemivagina opening 18 months after menarche due to heavy genital bleeding and abdominal pain after the end of menstruation.
