Between 1987 and 2002, 63 partial nephrectomy, including 34 open surgeries with renal hilar clamping (Group O), 9 open surgeries without hilar clamping and 20 laparoscopic surgeries without hilar clamping using a microwave tissue coagulator (Group L), were performed. Although operative time in Group L was significantly longer than that in Group O, postoperative hospital stay was shorter in Group L than Group O. Early and late complication rate and preserved renal functions improved with experience in Group O. Although in Group L late complication rate and preserved renal functions were better by experienced surgeons, early complication rate was not. A microwave coagulator is promising apparatus in minimally invasive treatment for small renal tumors, however, technical improvements, including monitoring and preventions for heat injury, are necessary for a widespread use of this apparatus.
