question: Hello, my father had axcel bi femeral bypass surgery to get rid of an infection.  This caused acute kidney failure.  His Creatinine level was up to 4.9 ish. He has been on dialisis several times now with his levels bearly moving after each treatment.  He is currently at 3.7.  He is also in congestive heart failure.  At what point would he need to have a transplant if his levels dont get undercontrol?
