To Summerize our initial experience of Robotic-assisted Nephroureterectomy and Extravesical Bladder-Cuff Resection (RNUBR), the technique of RNUBR without intraoperative reposition was described, and the early oncological results of our RNUBR with extravesical bladder-cuff resection for UUT-TCC was discussed.This is a single-center retrospective study of 26 patients of UUT-TCC who underwent RNUBR in Shanghai Changhai Hospital from July 2012 to May 2015.There were 18 males and 8 females in this study.The mean age of the patients was 65.9 year.All patients had complains of symptoms, including painless gross hematuria in 19 patients, hydronephrosis in 2, and lumbago in 2.All patients had confirmation of UUT-TCC by CT/MRI and preoperative biopsy under flexible ureterosopy.The preoperative clinic tumor stages of all patients were T1N0M0,including 17 cases of ureteral cancer and 9 cases of renal pelvis carcinoma, 15 cases in the left and 11 cases in the right.The standard paracaval or retrocaval lymphadenectomy is performed for the UUT-TCC on the right side,and the paraaortic or retroaortic lymphadenectomy for the left side.
