Abstract：To summarize the experience of transperitoneal approach robotic-assisted laparoscopic surgery in renal large tumor and to discuss the technical safety and surgical outcomes in single center. Methods: We retrospectively analyzed the clinic data of 29 patients with renal large tumor undergoing transperitoneal approach robotic-assisted laparoscopic surgery in our center, and summarized the clinical characteristics and operative outcomes. Results: 101 cases underwent robotic-assisted laparoscopic radical nephrectomy during 2008 October to 2015 April. Among all these cases, 29 were diagnosed as renal large tumor (28.7% of the cases given radical nephrectomy), including 20 males and 9 females with the mean age of (54.9±11.9) years old;. Fourteen tumors were located in the left kidney, and 15 in the right kidney. The maximum diameter was 16 cm and average diameter was (9.56±2.36) cm. Eleven cases (39.29%) were complicated with tumor thrombosis. Twenty cases were accomplished by transperitoneal approach and all procedures were technically successful without open conversion. All the 11 cases combined with tumor thrombus were treated with renal artery embolization. Average operative time was (164.4±40.0) min and average blood loss was 50-1 200 mL. The gastrointestinal function recovered
