Acquired bladder diverticulae are herniations of the bladder mucosa through detrusor muscle. Due to the ineffective emptying of the bladder diverticulum, urine accumulation may lead to urinary tract infection, stone disease, and lower urinary tract malignancy in the diverticulum. We report a case of laparoscopic bladder diverticulectomy for transitional cell carcinoma in an acquired bladder diverticulum. To our knowledge, this is the third case of laparoscopic diverticulectomy for a tumor. We report our experience with this case and the technical challenges encountered during the operation, together with literature review.
