The time for chronic kidney disease stage 4 to develop into uremia needs to be decided according to the control of the patient’s primary disease, if it is well controlled, it usually takes about 3~5 years; if it is combined with low blood pressure, urinary tract obstruction, etc. it may develop into uremia in a few days.
Chronic kidney disease stage 4 is defined as creatinine clearance (GFR) fluctuates between 15~29ml/min, and uremia is defined as GFR <10ml/min.
Patients with chronic kidney disease stage 4 are recommended to first control the primary disease and find the underlying cause of chronic renal failure, such as patients with diabetic nephropathy, need to control the blood pressure level, blood glucose level, blood lipid level under the guidance of the doctor, and need to orally take renin-vasculin and tensor-aldosterone receptor antagonist (valsartan, Benadryl) to slow down the progression of renal disease.
The development of chronic kidney disease stage 4 to uremia stage needs to be based on the control of the primary disease and complications, if the primary disease is well controlled without obvious complications, it may last for 3~5 years before developing into uremia; if the patient is combined with hypotension, severe infection, diarrhea, urinary tract obstruction, etc., it may develop into uremia within a few days.
Patients with chronic kidney disease stage 4 are advised to consult regular hospitals in time and follow the doctor's instructions for standardized treatment, and the above medication should be used without authorization.
