Overview

• The groundbreaking surgery, performed on May 4, 2025, at Ronald Reagan UCLA Medical Center, was led by Drs. Inderbir Gill and Nima Nassiri.
• Oscar Larrainzar, a 41-year-old father of four, regained kidney and bladder function after seven years of dialysis and a nonfunctional bladder due to cancer treatment.
• The eight-hour procedure involved transplanting a kidney and bladder from the same donor, with immediate restoration of urinary and renal function.
• This operation is part of a UCLA-led clinical trial aiming to evaluate the safety, feasibility, and long-term outcomes of bladder transplantation.
• Bladder transplants offer a more physiological alternative to intestinal bladder reconstruction, potentially reducing risks like infections and metabolic imbalances.
