Peritoneal Catheter Insertion

Your kidneys are responsible for removing extra fluid and waste from your body. If your kidneys fail, waste can build up in the blood and cause extreme sickness or death. Peritoneal dialysis can help people who are suffering from kidney failure get rid of the excess fluids and waste.

How Peritoneal Dialysis Works

During peritoneal dialysis, a liquid solution is pumped into the abdominal cavity. This solution contains dextrose, a sugar that pulls waste and extra fluid through the peritoneum, the lining of the abdomen. That abdomen is now filled with a liquid solution containing the excess fluid and waste that would normally be removed by the kidneys. This fluid is now drained from the abdomen. The filling and draining of the abdomen is repeated several times.

There are two types of peritoneal dialysis:

  • Continuous Ambulatory Peritoneal Dialysis: the patient fills the abdomen with dialysis solution and goes on with her day. After 4 or 5 hours, the patient drains and discards the solution. This is repeated several times during the day.
  • Continuous Cycler-Assisted Peritoneal Dialysis: a machine is used to fill and empty the abdomen several times while you sleep. In many cases, the abdomen will also be filled once at the beginning of the day and drained again at the end of the day.
