Acute Nephritis usually occurs after infection such as upper respiratory tract infection, skin infections and so on. Early inspection of Chronic Nephritis is very important for its treatment in time. The clinical symptoms of the disease vary with different patients. Some patients may not have any clinical symptoms. This kind of Nephritis is called subclinical Acute Nephritis. However, some patients may develop Renal Failure in several days in several days after infection. The common clinical symptoms of Acute Nephritis are as follows:

patients will have hematuria and about 40% of patients have gross hematuria.
