Urinary bladder transplantation in humans - current status and future perspectives.

Area of Science:

• Regenerative Medicine
• Transplant Surgery
• Urology

Background:

• Urinary bladder conditions necessitate alternative treatments to traditional urinary diversion.
• Intestinal segments used in urinary diversion can cause adverse effects.
• Vascularized bladder allograft transplantation is being investigated as a potential solution.

Purpose of the Study:

• To evaluate the feasibility and safety of vascularized bladder allograft transplantation.
• To explore robot-assisted surgical techniques for bladder allograft procedures.
• To compare bladder transplantation with existing urinary diversion methods.

Main Methods:

• A successful urinary bladder autotransplantation was performed in a brain-dead donor.
• Robot-assisted surgery was utilized for allograft collection and complex anastomoses.
• Ongoing clinical trials are assessing the technique in various patient populations.

Main Results:

• Robot-assisted surgery demonstrated optimal performance in bladder allograft procurement and reconstruction.
• Vascular, ureterovesical, and vesicourethral anastomoses were successfully achieved.
• The procedure offers a potential alternative to intestinal urinary diversion.

Conclusions:

• Vascularized bladder allograft transplantation is a promising alternative for end-stage bladder diseases.
• Robot-assisted surgery is a suitable technique for this complex procedure.
• Lifelong immunosuppression is necessary, and ongoing trials will determine safety and efficacy.
