Abstract：Objective:To summarize our clinical experience of robot-assisted laparoscopic partial nephrectomy(RALPN), and to discuss its efficacy and safety. Methods:Between May 2013 and August 2013, 20 cases of T1 renal tumor treated with intraperitoneal robotic partial nephrectomy utilizing the da Vinci Si surgical system. The perioperative data were collected, and were compared with those performed the same operation in abroad and those performed laparoscopic partial nephrectomy( LPN) with the same team in internal. Results:All the operations were accomplished successfully. The mean lesion diameter was 2.9(0.8-6.0) cm; the mean operative time ( not including preoperative set-up time of the da Vinci Si surgical system )was 119(80-180)min; the mean warm ischemia time were 17(10-25)min; the mean estimated blood loss was 88(10-300)ml. The patients were ambulant in the 3th postoperative days, and tubes were removaled in 2.6(0-7)d, and mean hospital stay was 6.8(5-11)d. Postoperative serum creatinine increased 16.5(-1.5-48.6)μmol/L. No intraoperative or postoperative complication occurred. Pathology revealed that all 13 cases was clear cell renal cell carcinoma. All resection margins were negative. Neither local recurrence nor metastasis was observed during a follow-up of 1 to 3 months. Renal function of all patients was in the normal range. Conclusions:Robot-assisted laparoscopic partial nephrectomy can be safely performed in selected patients. and it is a feasible approach and a minimally invasive operation for T1 renal tumor.
