[Forms of urinary diversion--methods and imaging findings]

Area of Science:

• Urology
• Surgical Reconstruction
• Medical Imaging

Background:

• Urinary diversion is essential after cystectomy for conditions like urothelial cancer, neurogenic bladder, and bladder exstrophy.
• Two main types exist: incontinent and continent, with continent diversions further classified by catheterization needs.
• Key goals for urologists include achieving urinary continence and preserving upper urinary tract function.

Purpose of the Study:

• To review the principal types of urinary diversion used in surgical reconstruction.
• To describe the basic surgical features of various urinary diversion techniques.
• To present typical imaging techniques for evaluating post-cystectomy urinary diversions.

Main Methods:

• Literature review of urinary diversion techniques.
• Description of surgical features for incontinent and continent diversions.
• Overview of imaging modalities, emphasizing CT urography and MR urography.

Main Results:

• Urinary diversion is crucial for managing bladder dysfunction post-cystectomy.
• Continent urinary diversions require careful consideration regarding catheterization.
• CT urography and MR urography are increasingly vital for monitoring urinary diversions.

Conclusions:

• Understanding different urinary diversion types is critical for accurate image interpretation.
• Advanced imaging techniques like CT and MR urography enhance the control and assessment of urinary diversions.
• The choice of urinary diversion balances continence and upper tract preservation.
