What is Peritoneal Dialysis?
Peritoneal dialysis (PD) is a way for your body to remove waste products from your blood when your kidneys are no longer functioning properly. During the procedure, a cleansing fluid flows through a catheter into your abdomen. The peritoneum, or the lining of your abdomen, acts as a filter to remove waste products from your blood. After a set “dwelling” time, typically 4 to 6 hours, the fluid along with filtered waste products flows out through the catheter to be safely discarded. The main difference between peritoneal dialysis and hemodialysis is that hemodialysis requires an artificial kidney machine to filter blood whereas peritoneal dialysis uses the inside lining of your belly as a natural filter.
Which dialysis is right for me?
Both peritoneal dialysis and hemodialysis are equally effective for most people, so deciding which to receive is usually a matter of personal preference. PD may be recommended for children under the age of 2, people who still have some limited kidney function, and adults without other serious health complications. Hemodialysis is recommended for patients in poor health including patients who are obese or who have had multiple abdominal surgeries.
PD Pros:
- Fewer negative side effects such as nausea and cramping
- Greater flexibility in treatment schedule, allows for travel
- Fewer dietary restrictions and fewer medications
- Continuous therapy acts more like natural kidneys, easier on heart
PD Cons:
- Must be a part of your daily routine, seven days a week
- Run the risk of infection/peritonitis
- Need ample storage in home/bedroom for supplies
- Requires responsibility, detailed training, and a sterile environment
What To Expect For PD Catheter Placement
Before you can begin your PD treatments, you need to have a peritoneal dialysis catheter placed through your abdomen. Catheters are soft and flexible, made of silicone or other medical-grade material. Your vascular specialist will make a tiny cut through the peritoneum and push the catheter through the cut, with an exit site near the belly button. The procedure takes about 30 minutes and is minimally invasive, requiring only local anesthesia and sedation. Sound Vascular provides a comfortable outpatient setting for PD catheter placement.
After your PD catheter placement, you may feel mild pain and fatigue for a few days. You should keep your dressing dry and only shower when given approval by your doctor. Your doctor will also prescribe stool softeners for 3 to 4 days to avoid constipation–particularly important if you are taking prescription painkillers. 7 to 10 after surgery, you will return to your doctor to have the dressing changed, exit site cleaned, and to begin your PD training.
Patient experience is at the heart of what we do.
