Brief Summary

With the same tumor control rate as classic radical cystectomy, radical cystectomy with partial preservation of the prostate and seminal vesicle can effectively preserve penile erection and fertility, improve urinary control rate and shorten hospitalization time. In this project, transurethral resection of the prostate was used to remove part of the prostate, which further reduced the trauma of radical cystectomy and better preserved the nerves and urethral sphincter. Rapid intraoperative examination of resected tissue can provide a basis for the selection of surgical options. Robot-assisted radical cystectomy can perform pelvic lymph node dissection more accurately, preserve neurovascular complex more effectively, and improve the control effect of tumor and the protective effect of sexual function and reproductive function. In view of the shortcomings of the internationally accepted orthotopic ileal neobladder, this study improved the operation according to the physiological and anatomical characteristics, restored the orthophoria of the new bladder, maintained the consistency of physiological anatomy, and minimized the bladder pressure.

Outcome Measures

Primary Outcomes (1)

  • Post-operative urinary function

    Assess post-operative urinary function

    During each follow-up postoperatively, the assessment is evaluated 36 months postoperatively

Secondary Outcomes (2)

  • bladder cancer specific survival rate

    During each follow-up postoperatively, the assessment is calculated based on the 36 months result postoperatively

  • Sexual function

    During each follow-up postoperatively, the assessment is calculated based on the BCI score of 36 months postoperatively

Study Arms (2)

Prostate and seminal-sparing Cystectomy

EXPERIMENTAL

Patients undergoing transurethral resection and enucleation of the prostate before robot-assisted cystectomy

Procedure: Prostate and seminal-sparing Cystectomy

Conventional Radical Cystoprostatectomy

PLACEBO COMPARATOR

Patients undergoing conventional robot-assisted radical cystoprostatectomy

Procedure: Conventional Radical Cystoprostatectomy

Interventions

Adopt endoscopic enucleation technology to preserve the prostate capsule and part of the urinary control support structure to help restore urinary control and erectile functions

Prostate and seminal-sparing Cystectomy

According to the consensus standard program, remove the accessory tissues including the bladder,prostate and seminal vesicles

Conventional Radical Cystoprostatectomy
