Clinical Trial Summary

Bladder cancer is a common malignant tumor of the urinary system, radical resection plus urinary diversion is the first choice of treatment for muscle invasive bladder cancer. Urinary diversion of surgical options related to patient' survival and quality of life. In 2000, professor Chunxiao Liu invented "detaenial sigmoid neobladder", this surgical method overset the traditional intestinal detubularization approach, which detached the serosal layer with smooth muscle from the bowel without split it. This kind of neobladder is easier to construct and have less impact on intestinal function. So far, it has been implemented for more than 700 cases in Zhujiang hospital, the age of patients range from 9 months (bladder rhabdomyosarcoma) to 88 years old. The filed of standard radical bladder cancer resection includes the structure of the prostate and seminal vesicles. More and more studies and long-term clinical experience in our hospital have confirmed that capsule sparing cystectomy can achieve good tumor control and excellent functional recovery. Our project is going to perform a randomized controlled trial for capsule sparing cystectomy and conventional radical cystoprostatectomy and look forward to assess the cncology outcome and functional recovery of these two procedures which provide an objective basis for the patients undergoing orthotopic urinary diversion in the future.


Clinical Trial Description

CSC group:patients undergoing transurethral resection and enucleation of the prostate first, do not open the bladder neck to maintain the integrity of the bladder neck. The enucleated prostate capsule is preserved under laparoscopic surgery, and the urinary catheter is stretched during the operation to avoid implantation and metastasis. CRC group:patients undergoing conventional radical cystoprostatectomy. All the patients undergoing detaenial sigmoid neobladder after cystectomy and accept at least 36 months follow up. Followup: Each patient was evaluated at 3-month intervals for 1 year, at 6- month intervals for 2 to 3 years. Renal ultrasound, biochemical examination and urine culture were done every 3 to 6 months. Pelvic computerized tomography and retro-cystogram were performed 6 months postoperatively and annually thereafter. Urodynamic investigation and cystoscopic examination were done annually. Postoperative complications were classified as early (90 days or less) and late (greater than 90 days). Early and late complications were subdivided into those related and not related to the neobladder. Complication grade was classified according to the Clavien-Dindo system. Major complications were defined as grade III or higher. Daytime and nighttime continence levels were recorded postoperatively at patient interview. Continence was defined as complete if the patient was dry without a pad, satisfactory if no more than 1 pad was required and poor if the patient used more than 1 pad during the day or night. ;
