Surgeons at a hospital in Los Angeles, California have successfully performed the world's first human bladder transplant, hospital officials said.

The surgery, performed May 4 at Ronald Reagan UCLA Medical Center, is a promising development for other patients suffering from serious bladder disorders.

The recipient of the innovative procedure was Oscar Larrainzar, 41, a father of four who had a large portion of his bladder removed due to cancer several years ago, the University of California, Los Angeles, said in a statement Sunday.

Larrainzar later had both of his kidneys removed due to cancer and end-stage kidney disease and was on dialysis for seven years.

He received both a bladder and a kidney from an organ donor and had them successfully transplanted in an eight-hour operation, AFP reported.

"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.

Dr. Nima Nassiri, one of the surgeons involved in the historic transplant, said the procedure yielded positive results almost instantaneously.

"The kidney immediately made a large volume of urine, and the patient's kidney function improved immediately," Nassiri said.

"There was no need for any dialysis after surgery, and the urine drained properly into the new bladder."

Nassiri and fellow surgeon Inderbir Gill said full bladder transplants had not been performed previously due to the complex vascular structure of the pelvis, making it a technically difficult procedure.

"This first attempt at bladder transplantation has been over four years in the making," Nassiri said.

Previously, patients in need of bladder reconstruction could have one artificially created using a part of the intestines or have a stoma bag inserted to collect urine.

Those techniques had several short-term and long-term risks that doctors hope will be circumvented with the full bladder transplant, Nassiri said.

Dozens of US ice cream producers are planning to remove artificial colors from their products by 2028, a dairy industry group and government officials said on Monday.

The producers, which together represent more than 90% of ice cream sold in the US, are the latest food companies to take voluntary steps to remove dyes since Health Secretary Robert F. Kennedy Jr. in April said the US aimed to phase out many synthetic dyes from the country's food supply.

Several major food manufacturers, including General Mills, Kraft Heinz, J.M. Smucker, Hershey and Nestle USA, have previously announced their plans to phase out synthetic food coloring.

The 40 ice cream companies will remove Red 3, Red 40, Green 3, Blue 1, Blue 2, Yellow 5, and Yellow 6 from their retail products, excluding non-dairy products, according to the International Dairy Foods Association.

The IDFA announced the plan at an event at the US Department of Agriculture headquarters on Monday with Kennedy, FDA Commissioner Marty Makary and Agriculture Secretary Brooke Rollins.

"We know that our current health outcomes, especially for our children, are unsustainable and that American agriculture is at the heart of the solution to make America healthy again," Rollins said at the event, referencing a slogan aligned with Kennedy.

Rollins and Kennedy have worked closely together on food sector efforts like encouraging states to ban soda from the nation's largest food aid program.

Kennedy has blamed food dyes for rising rates of ADHD and cancer, an area many scientists say requires more research.

The IDFA said artificial dyes are safe, but that ice cream makers are taking the step in part to avoid disruption to sales from state efforts to phase out dyes from school foods and West Virginia's recent food dye ban.
