This procedure includes filtering waste materials and extra fluid from the blood using a dialysis machine. It usually takes place in a dialysis unit three times per week and calls for vascular access, such as a catheter or an arteriovenous fistula.

In this method of dialysis, the peritoneal membrane of the patient serves as a natural filter. Waste materials and extra fluid are evacuated through the peritoneal membrane when a catheter is used to deliver a dialysis solution into the abdominal cavity. Both at-home and clinical peritoneal dialysis are options.
