This video explains how to safely avoid ureteric injury during laparoscopic hysterectomy in a patient with unsuspected endometriosis. The surgeon demonstrates how abnormal pelvic anatomy can alter the ureter's course, making routine surgical steps potentially hazardous. Through a detailed operative demonstration, viewers learn how to identify the ureter, carefully dissect it free from surrounding fibrosis, and safely complete the hysterectomy. The video also discusses the importance of preserving the ureter's blood supply, selecting appropriate dissection techniques, and avoiding thermal injury. It is an excellent educational resource for understanding safe pelvic dissection in complex gynecologic surgery.
