Preparation for hemodialysis starts weeks or months before treatments actually begin, Mayo Clinic explains. Before hemodialysis can begin, surgeons must create a special access point and then must allow it to heal in place.

The graft uses an artificial tube to connect the blood vessels.

Hemodialysis is a procedure that replaces the function of unhealthy kidneys, notes Mayo Clinic. It is the most common treatment for advanced kidney failure. Hemodialysis treatments must be applied on a rigorously regular schedule to be fully effective. It is a crucial treatment that helps control blood pressure and levels of vital blood minerals such as potassium and sodium.
