Chronic kidney disease stage 3 cannot be cured because the glomerular filtration rate of chronic kidney disease stage 3 has reached 30-59mL/min, urinary albumin/urinary creatinine >30mg/g, moderate decrease in glomerular filtration rate, accompanied by mild anemia, weakness, loss of appetite, and increased blood creatinine value, and the remaining renal function is below 50% of normal, which is the stage of renal insufficiency loss of compensation, i.e. azotemia. Pathology shows glomerulosclerosis, diffuse tubular atrophy, and interstitial fibrosis with lymphatic and mononuclear cell infiltration. This shows that the chronic renal lesions have exceeded 50%.
