How many years can IgA nephropathy grade III be controlled is related to the severity of the disease and treatment effect, and cannot be generalized. If the patient’s condition is mild and the treatment effect is good, the progression of the disease can be delayed after active treatment, but the number of years can be controlled cannot be clarified; if the patient’s condition is severe and the treatment effect is poor, with the progression of the disease, the disease may soon develop into uremia. The 10-year renal survival rate of IgA nephropathy is 80%~85%, and the 20-year rate is about 65%. However, there is a great individual difference, some patients have a good long-term prognosis, which may not affect their life expectancy, but some patients rapidly progress to renal failure, which leads to a shorter life expectancy. If the patient’s condition is mild and the treatment effect is good, the progression of the disease can be delayed after active treatment; if the patient’s condition is severe and the treatment effect is poor, with the progression of the disease, the disease may quickly develop into uremia. Therefore, how many years can IgA Nephropathy Grade III be controlled usually can not be clear for a specific time. Patients with IgA Nephropathy Grade 3 are advised to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
