How many years can patients with lgA nephropathy control without failure is related to clinical symptoms, pathological types, treatment effects and individual differences, and it is not possible to specify the exact time. IgA nephropathy is a glomerular disease in which IgA or IgA deposits predominate in the glomerular mesangial area, which is the most common primary glomerular disease. If patients with lgA nephropathy have better treatment, the disease can be effectively controlled, and in general, the 10-year kidney survival rate is 80%~85%, and 20 years is about 65%. However, there are great individual differences, some patients have a good long-term prognosis, but some patients may rapidly progress to the stage of renal failure. Therefore, how many years can lgA nephropathy be controlled without failure cannot be specified. If you have IgA nephropathy, it is recommended to go to regular hospitals in time and standardize the treatment under the doctor’s guidance.
