Peritoneal dialysis (PD) is a treatment option for patients with severe chronic kidney disease. PD removes extra water, wastes, and chemicals from your body. However, this type of dialysis uses the lining of your abdomen to filter your blood. This lining is called the peritoneal membrane and acts as an artificial kidney. The process uses the patient’s peritoneal membrane across which fluids and dissolved substances (electrolytes, urea, glucose, albumin and other small molecules) are exchanged from the blood. Fluid is introduced through a permanent tube (PD catheter) in the abdomen and flushed out either every night while the patient sleeps (automatic peritoneal dialysis) or via regular exchanges throughout the day (continuous ambulatory peritoneal dialysis). PD is used as an alternative to hemodialysis. It has comparable risks and benefits, with the primary advantage being the ability to undertake dialysis treatment at home without visiting a medical facility.
