We performed partial nephrectomy using a microwave tissue coagulator for 6 patients with small renal tumor. All of 6 patients were successfully treated, although intraoperative and postoperative bleeding was seen in one patient, respectively. Blood transfusion was needed in no patient. In two patients renal calyx was noticed to be opened, and closed immediately. Partial nephrectomy using microwave tissue coagulator has been considered to be safe and effective treatment procedure for small renal tumor.
