What this trial studies

This clinical trial compares two surgical approaches for treating bladder cancer in men: Capsule Sparing Cystectomy (CSC) and Conventional Radical Cystoprostatectomy (CRC). The CSC method aims to preserve the prostate capsule during surgery, potentially leading to better postoperative outcomes and quality of life. Patients will undergo follow-up assessments every 3 to 6 months for up to 36 months to evaluate complications, urinary function, and overall health. The study includes a detailed analysis of postoperative complications and patient-reported outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adult males aged 20 and above with muscle invasive bladder cancer or recurrent bladder cancer that meets specific clinical criteria.

Not a fit: Patients with distant metastasis, prostate invasion, or significant preoperative health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and quality of life for men undergoing treatment for bladder cancer.

How similar studies have performed: Other studies have shown promising results with similar surgical approaches, but this specific comparison is novel.
