Study objective: Anatomic anomalies of the female reproductive genital tract affect approximately 5.5% of women [1].

Abstract

Study objective: Anatomic anomalies of the female reproductive genital tract affect approximately 5.5% of women [1]. The hemiuterus or class U4 by the European Society of Human Reproduction and Embryology / European Society for Gynaecological Endoscopy 2013 classification is a rare congenital malformation defined as a unilateral uterine development, with a contralateral part that could be either incompletely formed or absent. This class is divided into 2 subclasses depending on the presence or not of a functional rudimentary cavity (U4a/U4b) [2]. This work aimed to share our experience performing an hysteroscopic and laparoscopic combined technique to surgically manage this uterine malformation exploiting the hysteroscopic transillumination. Design: A step-by-step explanation of surgical technique with narrated video footage. Setting: Tertiary Level Academic Hospital "IRCCS Azienda Ospedaliero - Universitaria di Bologna" Bologna, Italy. Interventions: A 32-year-old woman with a symptomatic (severe dysmenorrhea and chronic pelvic pain) suspected U4a uterine malformation diagnosed at our center was scheduled for laparoscopic removal of the right uterine horn and ipsilateral salpingectomy exploiting the contemporary hysteroscopic transillumination guidance. We selected this approach to avoid possible complications owing to the anatomic anomalies that are very common in these cases [3,4]. After coagulation and section of the right round ligament at the uterine angle and opening of the right broad ligament, access to the retroperitoneum was obtained to directly visualize the entire course of ureter and the uterine artery.
