In a groundbreaking medical achievement, surgeons in Los Angeles, California, have successfully completed the world’s first human bladder transplant, according to hospital officials.
The pioneering surgery was completed on May 4 and over two weeks later today, there have been no complications, marking it a major advancement in transplant medicine.
The recipient, 41-year-old Oscar Larrainzar, had previously lost most of his bladder to cancer and had both kidneys removed due to cancer and end-stage kidney disease. He had been on dialysis for seven years before undergoing the groundbreaking procedure. During the eight-hour operation, Larrainzar received both a bladder and a kidney from a donor.
“The surgeons first transplanted the kidney, followed by the bladder; they then connected the kidney to the new bladder using the technique they had pioneered,” the UCLA statement said. The procedure was a success, with immediate results.
“The kidney immediately made a large volume of urine, and the patient’s kidney function improved immediately,” said Dr. Nima Nassiri. “There was no need for any dialysis after surgery, and the urine drained properly into the new bladder.”
Until now, full bladder transplants had never been done due to the complexity of the pelvic vascular system. Most patients relied on reconstructed bladders from intestinal tissue or external urine collection devices. “This first attempt at bladder transplantation has been over four years in the making,” Nassiri said, expressing hope that this approach may reduce complications seen with older methods.
