The treatment of chronic renal failure primarily requires identifying the cause and treating it accordingly. Chronic renal failure refers to the state in which various diseases damage the kidneys, leading to the destruction of kidney tissue and resulting in the kidneys' inability to adequately excrete metabolic waste, causing an accumulation of such wastes in the body. There are no medications that can directly affect the kidneys, regenerate kidney tissue, and restore kidney function. Currently, medicine cannot achieve this, and there are no specific drugs for the treatment. Therefore, the treatment of chronic renal failure focuses on treating the primary disease to slow the progression of renal failure. For example, chronic renal failure caused by diabetes necessitates the use of insulin to control blood sugar, while patients with hypertension need to use antihypertensive drugs.
