Hemodialysis is a treatment for kidney failure that removes the blood from the body so it can be filtered through a dialzyer (artificial kidney) and then returned to the body. The blood is removed from and returned to the body through an access — either a vascular access, such as an arteriovenous (AV) fistula or AV graft, or in an emergency through a catheter. The blood is filtered many times during a four-hour treatment to remove wastes and extra fluid. Hemodialysis can be performed in a dialysis center or at home. There are several hemodialysis choices including: in-center hemodialysis, in-center self care hemodialysis, in-center nocturnal hemodialysis, traditional home hemodialysis and short daily home hemodialysis (done five to six times per week). In-center self care, in-center nocturnal hemodialysis and the home hemodialysis options may not be available in some areas throughout the United States.
Peritoneal dialysis (PD) removes wastes and extra fluid; however, it is performed within the body. The peritoneal cavity in the abdomen holds dialysis solution called dialysate, and the peritoneum, the membrane around the cavity, acts as a filter. A PD catheter, which is a small, flexible tube, is placed in the abdomen so the peritoneal cavity can be filled with dialysate. Waste passes through the peritoneum into the dialysate, which is then drained and replaced after an amount of time prescribed by the doctor. PD is performed at home, but can also be performed at work or in any other clean environment. The types of PD include: automated peritoneal dialysis (APD), which consists of continuous cycling peritoneal dialysis (CCPD) performed with a machine called a cycler, and continuous ambulatory peritoneal dialysis (CAPD), which is performed manually. PD is a dialysis option wherever home dialysis is offered.

Many dialysis patients may not be aware they have choices when it comes to their dialysis treatment. Sometimes patients on one modality switch to another modality as their health or lifestyle needs change. Talk to your doctor to find out which treatment may be right for you.
