Partial nephrectomy is often selected for surgical treatment of small renal cell carcinoma (RCC) with its favorable prognosis. To determine the therapeutic outcome of partial nephrectomy using microwave tissue coagulator (MTC), we evaluated our series of 129 patients with T1 RCC who underwent this procedure.In 121 open surgery cases, no significant deterioration of the renal function as indicated by creatinine clearance was observed. the5-year overall-survival rate was 91% during a mean follow-up period of 40 months, and 106 patients were alive without disease. One patient showed local recurrence two years later. In eight laparoscopic surgery cases, no patient showed local recurrence.We concluded that non-ischemic partial nephrectmy using MTC is a useful nephron-sparing surgery for small RCC in terms of the prognosis and the postoperative renal function.
