Los Angeles— In a groundbreaking medical achievement, Dr. Inderbir Singh Gill, a globally renowned urologist and leader in robotic surgery, has co-led the world’s first successful human bladder transplant at the Ronald Reagan UCLA Medical Center.
Performed on May 4, 2025, the eight-hour procedure involved transplanting both a bladder and a kidney from a deceased donor into 41-year-old Oscar Larrainzar, who had spent seven years on dialysis after losing both kidneys and most of his bladder to cancer treatment.
Key Facts:
-
Historic Procedure: On May 4, 2025, surgeons at UCLA and USC performed the world's first human bladder transplant, marking a significant milestone in medical history.
-
Patient Background: The recipient, 41-year-old Oscar Larrainzar, had lost most of his bladder and both kidneys due to cancer, leading to seven years on dialysis.
-
Surgical Team: The complex eight-hour surgery was led by Dr. Inderbir Gill of USC and Dr. Nima Nassiri of UCLA, following over four years of collaborative research and preparation.
The surgical team, led by Dr. Gill and Dr. Nassiri, spent over four years preparing for the historic operation, refining their techniques through extensive research and practice surgeries on deceased donors.
The procedure involved transplanting a donor kidney and bladder into Larrainzar, with the new kidney immediately producing urine and the bladder functioning normally post-surgery.
Dr. Gill, who completed his initial medical education in India before moving to the U.S. in 1989, emphasized the significance of the achievement:
"This is a landmark moment in organ transplantation. Until now, bladder transplantation was considered unfeasible due to the organ’s intricate vascular and nerve anatomy. This success opens a new frontier in treating patients with irreversible bladder dysfunction."
The success of this procedure offers a promising alternative to traditional treatments for bladder failure, which often involve using parts of the intestine to create a urinary reservoir—a method associated with numerous complications.
By transplanting a donor bladder, patients may avoid these issues, leading to improved quality of life.
UCLA plans to perform more bladder transplants as part of an ongoing clinical trial, aiming to expand access to this life-changing procedure and study its long-term outcomes.
This pioneering surgery not only represents a significant advancement in urologic and transplant medicine but also holds particular resonance for the Indian diaspora, highlighting the global impact of Indian-origin medical professionals.
Do You Know?
Before this breakthrough, bladder transplants were deemed unfeasible due to the organ's complex vascular and nerve anatomy.
This successful procedure challenges that notion, opening new possibilities in transplant medicine.
Key Terms:
-
Bladder Transplant: A surgical procedure involving the replacement of a diseased or non-functioning bladder with a healthy donor bladder.
-
Dialysis: A medical treatment that replicates kidney functions for patients with kidney failure, often involving the removal of waste and excess fluids from the blood.
-
Immunosuppression: The medical suppression of the immune system's activity, typically to prevent rejection of transplanted organs.
