Final answer:
Peritoneal dialysis is a type of dialysis procedure that uses the patient's own peritoneum to filter waste and excess water from the body. The number of patients using peritoneal dialysis can vary, as it depends on individual circumstances and preferences. However, it is a commonly used method in dialysis treatment.
Step-by-step explanation:
In peritoneal dialysis (PD), the patient's own peritoneum is used as a natural filter to remove waste products and excess water from the body. This type of dialysis is typically done at home and can be performed by the patient or a caregiver. A catheter is placed into the abdomen, and a special dialysis solution is introduced into the peritoneal cavity. The dialysis solution draws waste and extra fluids from the blood vessels in the peritoneum.
It's important to note that not all dialysis patients use peritoneal dialysis. The choice of dialysis method depends on various factors such as the patient's health condition, preference, and suitability for different types of dialysis.
Therefore, the number of patients receiving dialysis using PD can vary depending on individual circumstances. However, peritoneal dialysis is a commonly used dialysis method and provides a viable option for many patients.
