I know of one person (my friend's mom) who literally got this procedure done: she needed a new kidney, and they waited till a death row convict came along who was a match. When she was matched, she got a phone call to come over to that particular city quickly, and she went there, and came back a few days later with a brand new pair of kidneys. It was almost like when you give your car in for repair, and when it's ready they call you.
Her justification: this guy was going to die anyways, why not save someone's life in the process?
Rumor is also that SF Chinatown politician Rose Pak[1] got such a procedure done as a favor from the CCP government. She was extremely powerful, and CCP wanted to curry favor with her. When she got back from her "treatment", the entire who's who of SF ruling class showed up at the airport to receive her [2].
