Abstract：Objective:To assess the clinical efficacy of retroperitoneal laparoendoscopic single-site radical nephrectomy (LESSRN) versus standard laparoscopic radical nephrectomy (SLAN). Methods:Between April 2011 and August 2012,53 patients with renal cancer in our center underwent retroperitoneal LESSRN by using a homemade single-port device, and during the same period, 53 cases undergoing SLAN were randomly analyzed. The clinical and pathological parameters of the two groups were analyzed, including gender, age, body mass index, operative time, estimated blood loss, drainage volume of the wound, wound drainage tube removal, hospital stay, operative side, tumor size, tumor location, clinical TNM stage, Fuhrman grade, and complications. Results:No significant differences were found in gender, age, body mass index, operative time, estimated blood loss, operative side, tumor size, tumor location, clinical TNM stage, Fuhrman grade, and complications between two groups (P>0.05). The time of wound drainage tube removal and hospital stay in the LESSRN group were significantly shorter than in SLAN group (P<0.05). Conclusions:Compared with SLAN, retroperitoneal LESSRN using a homemade single-port device is a safe and feasible procedure for management of localized renal cancer, and have provided a better cosmetic outcome and shorter hospital stays.
