Medically reviewed by Last updated on Apr 2, 2024.

What is peritoneal dialysis?

Peritoneal dialysis is done to remove wastes, chemicals, and extra fluid from your body. A liquid called dialysate is put into your abdomen through a catheter (thin tube). The liquid stays in your abdomen for several hours at a time. This is called dwell time. The dialysate pulls wastes, chemicals, and extra fluid from your blood through the peritoneum. The peritoneum is a thin lining on the inside of your abdomen. The peritoneum works as a filter as the wastes are pulled through it. The process of filling and emptying your abdomen with dialysate is called an exchange.
