Abstract：Objective:To explore the laparoscopic anastomosis between the residual urethra and neobladder. Methods:From Jan. 2010 to Jan. 2014, the method of semicircle running suture from side to side with double needles was used to anastomose the residual urethra and neobladder in 46 patients with bladder urothelial carcinoma who underwent laparoscopic radical cystectomy and orthotopic urinary diversion. Results:The mean operating time for the anastomosis was 25 min (range 18 to 35 min). Slight urine leakage occurred in 3 cases postoperatively, which disappeared two weeks later naturally. The mean follow-up was 13 months(range 1 to 36 months), during which, all patients were diurnally continent. Conclusions:In view of the advantages such as short anastomositc time, simple manipulation and less complications, the method of semicircle running suture from side to side with double needles is worthy to be utilized in the anastomosis between the residual urethra and neobladder
