The patients included 30 males and 22 females, with an average age of (55.2±9.5) years old. There were 32 tumors in the left and 20 in the right. The mean lesion diameter was 4.5±0.7 cm. Results: All cases were performed successfully. The operation was completed in a mean of 80.5±12.3 min, the mean warm ischemia time was 17.4±5.1 min, the mean blood loss was 38.2±7.4 mL and the mean extubation time was 2.1±0.7 d. Postoperative pathology reported malignant tumor in all cases, including renal clear cell carcinoma in 45 cases, papillary renal cell carcinoma in 5 cases and chromophobe cell carcinoma in 2 cases. The surgical margin of all cases were negative. Conclusions: Retroperitoneal RALPN is an effective, safe and minimally invasive surgical management for T1b renal carcinoma.
