　Unicornuate uterus with a rudimentary horn represents a Müllerian duct anomaly. We describe three women aged 20, 18, and 23 years with a unicornuate uterus associated with a non-communicating rudimentary horn, who underwent successful laparoscopic surgery. Studies have reported a high incidence of endometriosis associated with this anomaly. Therefore, prevention of progressive endometriosis and rudimentary horn resection are recommended as treatment. We performed successful laparoscopic removal of a non-communicating rudimentary horn, ipsilateral fallopian tube, and endometriotic ovarian cyst in our patients who underwent uneventful laparoscopic surgeries, following preoperative imaging to accurately confirm the course of the uterine artery. We performed magnetic resonance angiography (MRA) and computed tomography angiography for preoperative evaluation. Preoperative confirmation of the course of the uterine artery is essential, and MRA is a particularly useful modality in such cases.
