Use of an endoscopic ultrasound probe for the evaluation of the Müllerian rudiments in patients with Rokitansky syndrome

Objective: To assess the use of an endoscopic ultrasound probe in the evaluation of the uterine horns in a series of patients who were undergoing laparoscopy for the creation of a neovagina. Design: Prospective study. Setting: Department of Obstetrics and Gynecology in a tertiary care and referral center for Rokitansky syndrome. Patient(s): Thirty patients with Rokitansky syndrome who were undergoing laparoscopically assisted creation of a neovagina. Intervention(s): Preoperative assessment with a pelvic transabdominal ultrasound scan and pelvic magnetic resonance imaging (MRI). An endoscopic ultrasound probe was used to study the uterine horns during laparoscopy. Main Outcome Measure(s): Presence or absence of the uterine rudiments, presence or absence of the endometrial cavity, and Doppler ultrasound vascularization of the rudiments. Result(s): Of the 24 uterine horns sized ≥2 cm that were identified at endoscopic ultrasound, 22 and 19, respectively, had been recognized at MRI and transabdominal ultrasound scan. The endoscopic ultrasound probe diagnosed 12 cavitated horns, of which 9 and 7 were seen at MRI and transabdominal ultrasound scan, respectively. Conclusion(s): Our experience shows the feasibility and accuracy of the endoscopic ultrasound probe in evaluating the structure of the rudimentary uterine horns in Rokitansky syndrome.
