Abstract: Objective To review our experience with intracorporeal laparoscopic radical cystectomy and sigmoid colon orthotopic neobladder reconstruction. Methods The clinical data of 26 cases of bladder carcinoma treated with the indicated surgical procedures were reviewed. Results The surgeries were successful in all the cases with the operating time ranging from 240 to 390 min, blood loss of 400 to 800 ml and red-cell transfusion of 0-4 U. Oral food intake was allowed 4-8 days after the operation, ureteral stents were removed in weeks 3 to 8 and the pouch catheter was removed in week 4 postoperatively. Daytime urinary continence was excellent and urinary incontinence at night occurred in 8 patients 3 months after the operation. Conclusion Sigmoid colon orthotopic neobladder reconstruction can be effective for urinary diversion to ensure good quality of life of the patients.
