Retroperitoneal Laparoscopic Wedge Resection for Small Renal Tumor using Microwave Tissue Coagulator

Abstract
A patient with a small renal tumor underwent a successful retroperitoneal laparoscopic wedge resection using a microwave tissue coagulator without renal pedicle clamping or surface cooling. There were no postoperative complications, and renal function was well preserved. This minimally invasive procedure may be useful for treating small renal tumors.
