Vaginoscopic Management of OHVIRA (Obstructive Hemivagina and Ipsilateral Renal Agenesis)

Abstract

To describe the vaginoscopic management of longitudinal vaginal septum in the case of obstructive hemivagina and ipsilateral renal agenesis (OHVIRA) syndrome. Surgical video describing step-by-step management. OHVIRA syndrome also known as Herlyn-Werner-Wunderlich syndrome is a triad of obstructed hemivagina, uterus didelphys, and ipsilateral renal anomaly [1] (Supplimentary Video 1). Patients usually present after menarche with progressive dysmenorrhea, lower abdominal pain, a paravaginal mass, foul mucopurulent discharge, and intermenstrual bleeding due to hemi hematocolpos [2]. Magnetic resonance imaging is the choice of investigation [3]. Surgical resection of the septum is the choice of treatment, which can be done vaginoscopically to reduce postoperative pain and promote enhanced recovery [4]. In this video, we will demonstrate a case of a 28-years old, nulliparous woman diagnosed with uterine didelphys having lower abdominal pain and persistent vaginal discharge. The video demonstrates the technique of vaginoscopic excision of the right hemi-vaginal septum that resulted in complete visualization of both cervices. Diagnostic laparoscopy confirmed uterine didelphys. The left cervix was visualized and the hysteroscope was negotiated into the cervical canal (Supplimentary Video 2). The left cavity was normal with left ostia. Intraoperative transrectal-ultrasound was done to localize the cystic collection in the right hemivagina. Needle aspiration of cystic collection was done over the bulging portion of the right hemivagina and mucoid material was aspirated. Longitudinal obstructive vaginal septum was incised using a collins knife and mucoid secretions were drained (Supplimentary Video 3). Hysteroscope inserted into opened right hemivagina, negotiated through the right cervix and right hemiuterus with right ostia was visualized. The residual septum was resected with a loop electrode and hemostasis was ensured. Cystoscopy done, left ureteric orifice with urine reflux visualized. Vaginal examination showed both cervices with near normal reconstructed vagina. The possibility of OHVIRA syndrome should be considered in all cases of uterine didelphys. Vaginoscopic management is a safe and effective method with a minimally invasive approach.
