Ureteral diverticula, especially acquired diverticula, are rare. Surgery is indicated when a diverticulum is accompanied by complications such as stones, pyelonephritis, stenosis, and signs of malignancy. A 59‐year‐old woman visited our urology department with asymptomatic macrohematuria. Enhanced CT scan revealed a right ureteral diverticulum with a 16‐mm diameter that contained two tiny stones inside. After 8 months, the size of these stones increased; therefore, the patient underwent laparoscopic resection of the ureteral diverticulum and end‐to‐end anastomosis of the ureter. Subsequent histopathology of the excised specimen revealed an acquired diverticulum. Follow‐up intravenous pyelography showed adequate urine passage with only minor dilatation of the pelvis at 3 months after the operation. The laparoscopic approach is believed to be feasible for ureteral diverticula cases that require ureteral end‐to‐end anastomosis.
