Chronic Vaginal Discharge Syndrome Caused by Obstructed Hemivagina and Ipsilateral Renal Agenesis (OHVIRA) Syndrome: A Case Report

引用

Case Reports in Clinical Medicine 2024年第7期13卷 227-233页

作者： Arja Alemu Nathan ross Department of Obstetrics and Gynecology AGC Tenwek Hospital Bomet Kenya Department of Obstetrics and Gynecology Soddo Christian Hospital Soddo Ethiopia

Background: Vaginal discharge syndrome is a common condition across the world with the main causes being infectious. Rare causes include obstructed hemivagina with ipsilateral renal agenesis (OHVIRA syndrome). Case Presentation: This case involves an 18-year-old woman with a 9-year history of vaginal discharge treated unsuccessfully by multiple physicians and different health facilities. After she presented to our hospital gynecology clinic with the same complaint she investigated with blood, urine, discharge wet-mount, pelvic ultrasound, and abdominopelvic computed tomography at different times. Preoperatively she was suspected to have OHVIRA syndrome which was successfully surgically treated with a full return of function. Conclusion: This case emphasizes the need to consider non-infectious causes commonly congenital mullerian anomaly in young women presented with long-time vaginal discharge symptoms soon after menarche and which are nonresponding to different multiple medical treatments. In peripheral health institutions like ours, it is best to consider computed tomography if available but better not to forget at least abdominopelvic ultrasound to look for congenital Mullerian anomalies.
