Home kidney dialysis was more convenient for patients and could be done more frequently, improving the health of patients. However, home kidney dialysis machine were expensive and complex to use and maintain. In hemodialysis, an artificial kidney (hemodialyzer) is used to remove waste, unnecessary chemicals and liquids from your blood. In order for your blood to enter the artificial kidney, the doctor must make an access to your blood vessels. This is done by minor surgery on your arm or leg. If your doctor tells you that you are a candidate, you can choose to put yourself on a waiting list for a new kidney.
