Hemodialysis and peritoneal dialysis have been done since the mid 1940's. Dialysis, as a regular treatment, was begun in 1960 and is now a standard treatment all around the world. CAPD began in 1976. Thousands of patients have been helped by these treatments.
Peritoneal dialysis uses a fluid that is placed into the patient's stomach cavity through a special plastic tube to remove excess waste products and fluid from the body. During hemodialysis, blood passes from the patient's body through a filter in the dialysis machine, called a dialysis membrane.. For this procedure, the patient has a specialized plastic tube placed between an artery and a vein in the arm or leg (called a gortex graft).
