Abstract

  Purpose：To evaluated the efficacy and safety of laparoscopic partial nephrectomy（LPN）, we compared the results of ischemic LPN with hilar occlusion （ischemia group）and non-ischemic LPN using microwave tissue coagulator（non-ischemia group）.
  Methods：Between April 1994 and April 2010, 54 patients underwent pure LPN. We retrospectively made a comparative review of perioperative complication and postoperative renal function between two procedures. Results：The patients with complication who received non-ischemic LPN developed prolonged urine leakage and finally, he required nephrectomy due to uncontrollable infection.
  Postoperative estimated GFR in non-ischemia group was significantly worth than that in ischemia group at 3 months after operation.
  Conclusion：The thermal damage by Microwave tissue coagulator may unexpectedly broad and deep. Although non-ischemic LPN using microwave tissue coagulator is technically easy, it should be restricted to use for the small superficial renal tumors.
