Comparing Hemodialysis With Peritoneal Dialysis

When the kidneys fail, waste products and excess water can be removed from the blood by hemodialysis or peritoneal dialysis.

In hemodialysis, blood is removed from the body into a dialyzer (called an artificial kidney), which filters the blood. An artificial connection between an artery and a vein (arteriovenous fistula) is made to facilitate the removal of blood.

In peritoneal dialysis, the peritoneum is used as a filter. The peritoneum is a membrane that lines the abdomen and covers the abdominal organs, creating a space within the abdomen called the peritoneal space or abdominal cavity.
