What is the medical procedure called that removes waste products from the blood in patients with kidney failure?

Dialysis is the medical procedure specifically designed to perform the function of the kidneys in patients experiencing kidney failure. In this process, a machine filters waste products, excess fluids, and electrolytes from the blood, essentially substituting the role of healthy kidneys. It helps to maintain the body's chemical balance and prevent the harmful accumulation of toxins.

Transfusion refers to the process of transferring blood products into an individual's bloodstream, which is unrelated to waste removal from the blood. Urinalysis is a diagnostic test that examines urine to assess various health conditions but does not involve direct treatment or waste removal from the blood. Infusion generally entails administering fluids, medications, or nutrients directly into the body, which also does not relate to the specific need for waste removal in kidney failure.

Overall, dialysis directly addresses the physiological need for cleansing the blood in patients whose kidneys are unable to perform this critical function.
