Peritoneal dialysis (PD) is a type of dialysis which uses the peritoneum in a person's abdomen as the membrane through which fluid and dissolved substances are exchanged with the blood.It is used to remove excess fluid, correct electrolyte problems, and remove toxins in those with kidney failure.Peritoneal dialysis has better outcomes than hemodialysis during the first couple of years.Other benefits include greater flexibility and better tolerability in those with significant heart disease.Complications may include infections within the abdomen, hernias, high blood sugar, bleeding in the abdomen, and blockage of the catheter.Use is not possible in those with significant prior abdominal surgery or inflammatory bowel disease.It requires some degree of technical skill to be done properly
