Resection of Vaginal Septum in Obstructed Hemivagina and Ipsilateral Renal Anomaly: Utility of Three Dimensional Intraoperative Ultrasound

Abstract

Background: Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare congenital condition of the female urogenital tract, presenting intraoperative challenges. We demonstrate the utility of three dimensional intraoperative ultrasound to better delineate anatomy and aid in optimal resection of the vaginal septum. Case: A 12-year-old female was referred to pediatric and adolescent gynecology for irregular periods and evaluation of her gynecologic organs. Imaging studies confirmed OHVIRA syndrome. She underwent uncomplicated vaginal septum resection, guided by three dimensional intraoperative ultrasound. Summary and Conclusion: Intraoperative ultrasound can better delineate challenging anatomy. We show that three dimensional intraoperative ultrasound offers significant advantages over traditional two dimensional ultrasound and is a supplement to MRI, which may be helpful in complex anatomical cases like OHVIRA syndrome.
