I want to ask the difference between abdominal dialysis and hemodialysis

Hemodialysis and peritoneal dialysis are treatments to remove impurities from body fluids and maintain normal life. They are mainly used for patients with renal failure. Hemodialysis is better, but the cost is also more expensive, requiring arteriovenous fistula. Peritoneal dialysis is not as effective as hemodialysis, but the cost is lower.
