When your kidneys no longer function adequately on their own, one of several forms of dialysis or a kidney transplant are your options. Dialysis acts as an artificial kidney that mechanically removes waste and excess fluid from the body. A kidney transplant replaces a damaged kidney with a new, healthy organ. If you are facing kidney failure -- also referred to as end-stage renal failure or end-stage renal disease (ESRD) -- and must make this choice, we help you understand your options and choose the treatment that is right for you.
