Chronic kidney failure is irreversible and incurable, with no possibility of kidney function recovery. There are many causes of chronic kidney failure, commonly including diabetic nephropathy, hypertensive nephropathy, chronic nephritis, polycystic kidney disease, etc. These causes affect the kidneys over the long term, resulting in extensive damage to kidney tissues. Since kidney tissues cannot regenerate, chronic kidney failure is incurable and irreversible. Patients with chronic kidney failure still require treatment to control the underlying causes leading to the condition, aiming to slow down the progression of the disease as much as possible, prolong the patient’s life, and ensure the quality of life. This is the primary goal of treatment.
