Peritoneal Dialysis
Peritoneal dialysis is a home-based treatment for kidney failure that uses the natural lining of the abdomen, called the peritoneum, to remove waste products and excess fluid from the blood. A soft catheter is placed into the abdomen, allowing dialysis solution to flow in and out during treatment.
How Does Peritoneal Dialysis Work?
During an exchange, dialysis fluid enters the abdominal cavity through the catheter and remains there for a prescribed period. The solution absorbs waste and extra fluid before being drained and replaced with fresh solution. Treatment may be performed manually during the day or with an automated cycler, usually while sleeping.
Types of Peritoneal Dialysis
The two main options are Continuous Ambulatory Peritoneal Dialysis (CAPD) and Automated Peritoneal Dialysis (APD). Your nephrologist will recommend an approach based on your kidney function, lifestyle, medical needs, and ability to manage treatment at home.
Benefits of Peritoneal Dialysis
Peritoneal dialysis can offer greater flexibility because treatment can be performed at home and, with appropriate planning, during travel. It does not require regular needle access to the bloodstream and may fit more easily around work and daily activities.
Risks and Care
Proper catheter care and sterile technique are essential because infections, including peritonitis, can occur. Other possible complications include hernia and weight gain. Patients should follow their dialysis schedule, dietary recommendations, fluid guidance, and regular medical reviews.
