Purpose : We evaluated retroperitoneoscopic patial nephrectomy for small renal tumors using microwave tissue coagulator.
Materials and Methods : From June 1999 to October 2001, 10 patients with small renal tumors of less than 5.0 cm in diameter (1.0-5.0cm, T1N0M0) underwent retroperitoneoscopic patial nephrectomy without renal pedicle clamping.
Result : All ten patients successfully underwent the procedure retroperitoneoscopically. Operative time was 180-405 minutes (median 275 minutes) and blood loss was 0-280mL (median 150mL). Postoperative hospitalization was 8-57 days (median 10.5 day). As a complication, one patient experienced a decrease in renal function and one patient showed severe urine leakage.
Conclusions : Retroperitoneal partial nephrectomy using a microwave tissue coagulator is less invasive method and useful, but only protruding tumors should be treated with this method.
