Peritoneal dialysis is a treatment option that uses the thin film of tissue lining your abdomen, called the peritoneum, as a natural filter to remove waste materials and excess fluids from your body.

Before you begin peritoneal dialysis, you will have an outpatient surgery to place a soft, flexible tube, called a catheter, through a small incision into your belly. The catheter has three parts: one part is placed into the cavity, the second part leads through the skin and the third part extends outside of the body. Once the site has healed, you will use the catheter to fill the inside of the peritoneal cavity with a cleansing fluid called dialysate. Waste materials and extra fluid pass through the peritoneal membrane into the dialysate and are later drained from your body through the catheter.
