The dialysis session works to remove toxins and fluids that the kidneys can no longer remove from the body. Dialysis also aims to maintain the balance of the body by correcting the levels of various toxic substances in the blood.

Without dialysis, all patients with complete renal failure are prone to death as a result of accumulation of toxins in the bloodstream. The dialysis session is therefore essential for the continuity of life that renal failure patients need 12 times a month with a dialysis machine that is a replacement for the kidney.
