We performed partial nephrectomy using a microwave tissue coagulator in 4 cases of renal cell carcinoma less than 20 millimeters in diameter. All cases were asymptomatic and the tumor was found incidentally. Tumors were resected using the microwave tissue coagulator at the power of 65W, 30 seconds for coagulation, followed by 15-25 seconds of dissociation. Mean blood loss was 73.3 mL (range : 10-140 mL), and mean operation time was 140 minutes (range : 131-157 min.). The indication in our hospital for partial nephrectomy using the microwave tissue coagulator is solitary tumors of less than 30 millimeters in diameter. We demonstrate the advantages of the non-ischemic procedure especially in intraoperative blood loss and operative time compared with five cases of conventional partial nephrectomy.
