There are two main manifestations of nephritic urine: i. Proteinuria. Second, hematuria. Proteinuria refers to the increase of foam in urine, and the general 24h urine protein quantification is greater than 0.15 g. Because urine protein is an independent risk factor for kidney injury, it must be treated by lowering urine protein, and the most commonly used drugs are ACEI and ARB class, such as Benazepril and Valsartan. Hematuria can be divided into microscopic hematuria and carnal hematuria. Hematuria is formed because red blood cells penetrate deeply into the urine through the damaged glomerular basement membrane, so checking urinary aberrant red blood cells is generally greater than 80%, which can be identified as glomerular origin and requires active kidney preservation therapy. The most commonly used drugs are Renfukang, Bailing Capsules and Haikun Renxi Capsules. Once nephritis is identified, it is recommended to review the blood routine, urine routine, ion kidney function, etc. once in 3-6 months.
