Peritoneal Dialysis

Peritoneal Dialysis

Peritoneal dialysis (PD) is a form of dialysis that uses the lining of your abdomen, called the peritoneum, to filter waste and excess fluids from your blood. This method allows patients with kidney failure to manage their condition at home, offering greater flexibility and independence compared to hemodialysis.

How Peritoneal Dialysis Works

The Procedure

Peritoneal dialysis involves the following steps:

  • Catheter Insertion: A soft tube (catheter) is surgically placed into the abdomen. This tube remains in place and is used for the dialysis process.
  • Dialysis Solution: A sterile dialysis solution is introduced into the abdominal cavity through the catheter. This solution absorbs waste products and excess fluids from the blood vessels in the peritoneum.
  • Drainage: After a set dwell time, the solution, now containing waste products, is drained from the abdomen and replaced with fresh solution.

Types of Peritoneal Dialysis

There are two main types of peritoneal dialysis:

Continuous Ambulatory Peritoneal Dialysis (CAPD)

  • Manual Exchanges: Patients perform manual exchanges of dialysis solution 3-5 times a day.
  • Flexibility: Allows for daily activities to continue as normal between exchanges.

Automated Peritoneal Dialysis (APD)

  • Machine-Assisted: A machine (cycler) automatically performs exchanges, usually while the patient sleeps.
  • Convenience: Offers flexibility and is done overnight, freeing up daytime hours.
