Lateral Prostate Capsule Sparing Versus Non Nerve Sparing Robot-assisted Radical Cystectomy-orthotopic Ileal Neobladder for Bladder Cancer in the Male

• Conditions: Bladder Cancer
• Interventions: Procedure: lateral prostate capsule sparing

• Registration Number: NCT04958330
• Lead Sponsor: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Brief Summary

To compare the perioperative, functional, and oncologic outcomes between non nerve sparing and lateral prostate capsule sparing robot-assisted radical cystectomy with orthotopic ileal neobladder in male patients with bladder cancer.

Detailed Description

This study will enroll male patients with bladder cancer who will undergo robot-assisted radical cystectomy with orthotopic ileal neobladder. The patients will be distributed into two comparable groups according to surgical procedures: non nerve sparing group and lateral prostate capsule sparing group. Patient demographics and pathologic, perioperative, functional, and oncologic outcomes will be compared between the two groups.
