Retroperitoneoscopic non-ischemic partial nephrectomy using a microwave tissue coagulator for T1a renal cell carcinoma

Abstract

We evaluated the perioperative complications and preliminary oncological outcomes in patients with T1a renal cell carcinoma (RCC) who underwent non-ischemic retroperitoneoscopic partial nephrectomy by using a microwave tissue coagulator (MTC). Seventeen patients (11 men and 6 women) with T1a RCC underwent this procedure at our institute. The mean age and tumor size were 59 years (range: 33-80) and 26 mm (range: 15-40), respectively. The mean operation time and estimated blood loss were 212 min (range: 120-266) and 128 mL (range: 5-570), respectively. No patient received transfusion. No patient showed intra-operative and post-operative urine leakage, bleeding, ileus, wound infection or renal insufficiency. The mean follow-up period was 42 months (range: 1-90). During the follow-up period, no patient showed any local recurrence or distant metastasis, and all patients are alive without cancer now. Non-ischemic retroperitoneoscopic partial nephrectomy by using an MTC is a less-invasive procedure for T1a RCC in patients selected by appropriate indication criteria.
