Experience of retroperitoneoscope-assisted partial nephrectomy using a microwave tissue coagulator for non-exophytic small RCC

Abstract

Retroperitoneoscopic nephron-sparing surgery using a microwave tissue coagulator (MTC) without renal ischemia is feasible as minimally invasive procedure for small renal tumor. However, the indication of this procedure is limited for exophytic small renal tumors because of uncontrollable urine leakage as a typical complication of MTC.
We performed retroperitoneoscope-assisted partial nephrectomy using MCT even for non-exophytic small renal cell carcinoma under 5-6 cm small skin incision. We report the points and pitfalls of the operative procedure.
