MouseGoddess, I'm so sorry to hear this.... in many cases of acute kidney failure (depending on the cause), kidney function can recover fully or partially. Have hope!
His sister and I went to see him this evening and he is in a chemically induced coma and on a respirator. They didn't tell us that on the phone when we talked to the nurse. It was a shock.....but I do still have hope.
Thanks to all, I do appreciate your comments and encouragement. I am constantly amazed at the kindness and caring of the people on these boards, more than any other forum I've ever seen.
