From MERCURY NEWS:
Without a new kidney, Jesus Navarro will die. He has a willing donor (his wife) and private insurance to pay for the transplant. But he faces what may be an insurmountable hurdle in the race to save his life: He is an illegal immigrant.
Administrators at UC San Francisco Medical Center are refusing to transplant a kidney from Navarro's wife, saying there is no guarantee he will receive adequate follow-up care, given his uncertain status.
I can't see what the surgeons' problem is here. The donated kidney is coming from the sick man's wife. She would not be donating it to anybody else so it's not a matter of who would be the best recipient of the kidney. Therefore, the surgeons appear to be asking if it is worth their time to do the surgery.
