A. It gives more independence and more closely resembles normal kidney function: Peritoneal dialysis allows patients to manage treatment at home, providing more flexibility and independence, and it mimics the kidney's natural filtration process.
B. It has literally no drawbacks: While peritoneal dialysis has benefits, potential complications include peritonitis, catheter infections, and hyperglycemia from the dialysis solution.
