Laparoscopic Nephron Sparing Surgery in Renal Tumor / 대한비뇨기과학회지

ABSTRACT

We report our initial experience of a laparoscopic nephron sparing surgery through retroperitoneal and transperitoneal approaches. One patient with a renal tumor for each approach underwent operations. Cooling technique was not used in either cases and an occlusion of the renal artery with laparoscopic bulldog clamp was performed in the second case. Complete removal of the renal tumor was achieved in both cases. Bleeding control and repair of the collecting system with watertight sutures were successful. The operative time was 2 h and 40 min, 4 h and 5 min in each, warm ischmic time was 15 min in the second case. The hospital stay was for 4 and 8 days. The final pathologic evaluation was for lipoma and renal cell carcinoma (3.5x3.5cm in size) with a negative surgical margin. A laparoscopic nephron sparing surgery is quite feasible and might be offered as an advantage over open surgery with regards to the length of hospital stay, convalescence time and cosmetic results with more experience. But, further long term follow-up for laparascopic nephron sparing surgery might be necessary.
