Abstract
It is important that the course of the ureter is noted during gynecologic surgery. Operations via laparoscopy are considered to be minimally invasive. However, such is not the case when other internal organs are injured during laparoscopic surgery, resulting in a deterioration in the patient's quality of life. We report here three cases of intraligamental uterine myomas which were removed laparoscopically without ureteral injury. The risk of ureteral injury is increased while enucleating broad ligament myomas. It is essential that gynecologic surgeons understand the local dissection of female pelvic organs. A water dissection technique is useful to avoid injury to the ureter.
