Surgeons at Massachusetts General Hospital have removed a pig kidney from a New Hampshire man 271 days after the innovative transplant .

Tim Andrews was 66 years old and suffering from end-stage renal failure when he received the genetically edited organ on Jan. 25. He holds the world record for longest time living with a pig kidney.

Mass General said Andrews has been experiencing "a period of decreasing kidney function." He will go back on dialysis and is still on the list to receive a human kidney.

Upon receiving the transplant in January, Andrews said, "I believe this is the start of something that's going to be fantastic."

"It's going to be the option for people that don't want to be on dialysis, they want to be able to be with their kids and loved ones," he said.
