Abstract

Objective: Laparo-endoscopic single-site surgery (LESS), an attempt to further enhance the cosmetic benefits of minimally invasive surgery while minimizing the potential morbidity associated with multiple incisions, has been recently developed. The aim of this study was to report the results of our initial LESS-simple nephrectomy (LESS-SN) experience and to define potential benefits.

Materials and methods: Between December 2008 and December 2009, LESS-SN were performed in 15 patients requiring simple nephrectomy by a single experienced surgeon. Patient characteristics, operative details and time to return to work were recorded.

Results: The mean operative time was 119.6±15 (range 100-150) min, blood loss was 52±18 (range 20-80) mL, and hospitalization time was 2.06±0.2 (range 2-3) day. The mean time to return to normal activities was 10.86±1.84 (range 9-15) days. No significant intraoperative or postoperative complications occured. 

Conclusion: The main advantages of LESS-SN are better cosmetic results and minimal postoperative pain. LESS-SN may take the place of conventional transperitoneal laparoscopic-simple nephrectomy and may be considered a routine, safe, and effective surgical procedure in simple nephrectomy for benign renal diseases.
