Patients with renal failure who have progressed to uremia need renal replacement therapy such as hemodialysis or peritoneal dialysis, and if they have not progressed to uremia, they can take renal protection and creatinine-lowering medication to control their condition. If renal failure has progressed to uremia stage, at this stage, the patient’s glomerular filtration rate is less than 10ml/min, renal damage has been irreversible, drug treatment is ineffective, and renal replacement therapy is needed, and hemodialysis and peritoneal dialysis are commonly used in the clinic. If the renal failure has not progressed to the uremic stage, drugs can be applied to alleviate the progression of the disease. ACEI or ARB drugs can be applied to control blood pressure, such as captopril, valsartan, etc. It should be noted that when the blood creatinine is greater than 256 μmol/L, bilateral renal artery stenosis patients should be careful to use this kind of drugs. At the same time, lipid-lowering drugs such as atorvastatin can be applied to control blood lipids; erythropoietin can be applied to correct anemia. Patients should go to the nephrology department of regular hospitals when they reach the stage of renal failure, and apply medication or renal replacement therapy under the guidance of doctors.
