What is the goal of dialysis in patients with renal failure?

The primary goal of dialysis in patients with renal failure is to remove waste and excess fluid from the blood. In cases of kidney failure, the kidneys are unable to effectively filter blood, leading to the accumulation of toxic substances and excess fluids in the body. Dialysis serves as an artificial replacement for the kidney's filtering function, helping to maintain physiological balance by clearing these harmful substances and managing fluid levels.

By performing this crucial role, dialysis helps to prevent complications that can arise from the buildup of waste products, such as uremia, and helps to regulate electrolyte levels, thereby contributing to the overall management of the patient's condition. While enhancing urine output or supporting the need for a kidney transplant may be considerations in treatment, they are not the primary objectives of dialysis itself. The emphasis is on achieving effective waste removal and fluid balance critical for the patient's survival and health maintenance.
