Chronic nephritis stage II, which cannot be completely cured. Chronic nephritis is one of the most common kidney diseases in clinical practice, and its typical clinical manifestations are hematuria, proteinuria, edema, hypertension, which can be accompanied by different degrees of renal hypofunction. Once chronic nephritis is diagnosed, the disease cannot be completely cured. However, it can be controlled by medications to protect the kidney function and prevent the deterioration of kidney function to avoid entering the uremic phase. The commonly used drugs are Irbesartan, Benazepril and Valsartan, which also have the effect of lowering urine protein and controlling blood pressure. The next step is to choose the drug treatment according to the urine protein quantification as well as blood pressure, creatinine and urea. If the creatinine urea is elevated, you can add urea pellets to lower the creatinine treatment. In addition to medication, we should also pay attention to the diet, based on the principle of low salt, low fat, high quality and low protein diet to avoid increasing the burden on the kidneys.
