US surgeons successfully transplanted a human bladder

American surgeons have successfully performed the world's first human bladder transplant, potentially revolutionizing treatment for patients with severe bladder issues. The recipient, 41-year-old Oscar Larrainzar, received a bladder and a kidney from the same donor during an eight-hour surgery. The kidney began producing urine immediately, and the patient's renal function improved, eliminating the need for dialysis post-surgery. Previously, bladder transplants were considered too complex. This successful procedure, developed over years, marks a historic moment and will be followed by clinical trials to assess its benefits and risks.
