Abstract

Laparoscopic partial nephrectomy has been recently applied as a minimally invasive procedure. Several non-ischemic operation devices for partial nephrectomy have been developed. Two patients with small renal tumors successfully underwent laparoscopic partial nephrectomy at our institution with using a microwave tissue coagulator without any immediate complication. The renal parencyme around the tumor was coagulated using a microwave tissue coagulator with a probe 1.5cm in length. The tumor was circumscribed within the coagulated area, and partial nephrectomy was performed using scissors. Laparoscopic non-ischemic partial nephrectomy using a microwave tissue coagulator may be feasible for treating selected small renal tumors.
