■ Laparoscopic calyceal diverticulectomy presented herein strictly adheres to open surgical principles.

■ The procedure includes:

■ clear identification of the diverticular cavity,

■ wide unroofing of the diverticular dome,

■ suture closure of the infundibular neck,

■ fulguration of the diverticular epithelium, and

■ obliteration of the diverticular cavity.

■ Patients with large diverticula with thin overlying renal parenchyma are ideal candidates for laparoscopic calyceal diverticulectomy.

■ High success rates and low morbidity can be achieved with laparoscopic calyceal diverticulectomy.
