[Studer-type orthotopic urinary bladder: our experience]

Area of Science:

• Urology
• Oncology
• Surgical Innovation

Context:

• Invasive bladder cancer necessitates radical cystectomy and urinary diversion.
• Bladder substitution with continent urinary pouches aims to improve quality of life post-cystectomy.
• The Studer reservoir is one such technique for creating a continent urinary diversion.

Purpose:

• To evaluate the outcomes, complications, and functional results of the Studer continent urinary pouch in male patients.
• To assess the oncological control and functional aspects of this specific bladder substitution technique.

Summary:

• Six male patients with invasive bladder cancer underwent radical cystectomy and Studer reservoir creation.
• Follow-up included imaging and laboratory tests; oncological outcomes varied, with 4 disease-free, 1 deceased, and 1 on chemotherapy.
• Functional results showed good medium-term reservoir function, maintained continence, and spontaneous micturition, though complications like ileus, wound infections, and impotence were noted. Operating time was longer than for Bricker diversion.

Impact:

• The Studer pouch demonstrates potential for good functional outcomes in bladder cancer patients requiring cystectomy.
• Highlights the importance of meticulous patient selection, surgical technique, and comprehensive postoperative care for success.
• Provides insights into the complication profile and long-term functional results of this reconstructive option.
