Peritoneal Dialysis is a CLINICAL INTERVENTION.
Peritoneal Dialysis is a form of Renal Dialysis which cleans the blood inside the body by running a Renal Dialysis fluid (dialysate) through a tube into the peritoneal cavity. The dialysate is left for a period of time to absorb the waste products and then drained out through the tube and discarded.
