OHVIRA syndrome pre-operatively diagnosed using vaginoscopy and hysteroscopy: A case report.

Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare Mullerian duct anomaly. Cases with pelvic inflammatory disease or endometriosis have been reported, which may influence fertility or the quality of life of patients; therefore, an accurate and early diagnosis is essential. The present study reports the case of patient (25-year-old female, gravida 0 para 0) with OHVIRA syndrome. Magnetic resonance imaging and a computed tomography scan revealed uterus didelphys and right renal agenesis. An opening was found on the vaginal septum during the menstrual period. Upon diagnostic vaginoscopy and hysteroscopy through the opening, the right vaginal cavity was enclosed, and the right uterine cervix and cavity were normal. The patient was diagnosed with OHVIRA syndrome. Her vaginal septum was surgically removed under direct visualization and the pathological findings of the resected septum revealed a benign squamous epithelium. The post-operative course was uneventful and restenosis of the vagina was not observed. On the whole, the present study demonstrates that the technique, diagnostic vaginoscopy and hysteroscopy, is minimally invasive and is sufficient for the diagnosis of incomplete vaginal obstruction-type OHVIRA syndrome.
