Cystectomy and urinary diversion

Area of Science:

• Urology
• Oncology
• Surgical Innovation

Background:

• Current bladder cancer treatments lack novel clinical benefits.
• Radical cystectomy is the most effective local treatment but is highly aggressive.
• Uncertainty regarding bladder cancer's natural history and cystectomy risks fuels debate on its indications.

Purpose of the Study:

• To discuss the necessity and variety of urinary diversion techniques post-cystectomy.
• To highlight the importance of understanding different diversion classes for urologists.
• To provide an overview of principles, advantages, and contraindications for various urinary diversions.

Main Methods:

• Review of existing literature on bladder cancer treatment and urinary diversion.
• Discussion of common principles, advantages, and contraindications of different diversion techniques.
• Categorization of diversions into incontinent diversion, ureterosigmoidostomy, continent reservoir, and orthotopic bladder substitute.

Main Results:

• Numerous urinary diversion and bladder substitute options exist.
• Patient-specific factors (tumor extent, age, function, acceptance) necessitate varied techniques.
• Urologists should be proficient in at least one technique from each major diversion class.

Conclusions:

• Effective management of bladder cancer requires careful consideration of cystectomy and subsequent urinary diversion.
• A foundational understanding of various urinary diversion techniques is essential for urologists.
• Tailoring diversion techniques to individual patient profiles is critical for optimizing quality of life post-cystectomy.
