Six patients with inferior and middle polar renal cysts of 8-15 centimeters of diameter, underwent the resection of the cyst by laparoscopic technique. The operation required an average time of execution of two hours and the positioning of four trochars to consent an adequate access. The absence of important complications during and after the operation has allowed a quick dismission of the patients. The laparoscopic treatment of renal cysts represent a valid choice to traditional surgery and percutaneous needle aspiration.
