We performed retroperitoneoscopic partial nephrectomy using microwave tissue coagulation without renal pedicle clamping. This procedure can be expected to be minimally invasive with minimal bleeding, while preserving renal function. However, this surgical procedure should be carefully selected for patients with tumors less than 2 cm in diameter, peripherally located, and with a distance of more than 1 cm between the tumor and the renal collecting system.
