Peritoneal Dialysis (PD)

Peritoneal dialysis (PD) is a way to remove waste products from your blood when your kidneys can no longer do the job adequately. A cleansing fluid flows through a tube (catheter) into part of your abdomen (peritoneal cavity) and filters waste products from your blood. After a couple of hours, the fluid with filtered waste products flows out of your abdomen and is discarded.

The peritoneum filters waste products from the blood. When there is a large amount of waste product in the blood, it will be released through the many blood vessels of the peritoneum and into the peritoneal cavity where the cleansing fluid is. Excess fluid will be removed through the blood vessels through the pressure of the glucose in the dialysis solution.
There are many types of peritoneal dialysis. Please discuss alternatives with your doctor.
