The prognosis of nephrotic syndrome in children needs to be decided according to the type of disease and the cause of the disease, for the milder symptoms can be cured, for the more complicated condition is not easy to cure. For primary acute nephrotic syndrome, most of the cases are caused by infections, the condition is simple and the cause is easy to be removed, if there are only minor micro lesions and mild peritoneal hyperplasia, such cases can be cured by timely treatment. However, for some secondary nephrotic syndrome, most of them are accompanied by underlying diseases, such as diabetic nephropathy, allergic purpura nephritis and so on, and even some children have some congenital genetic defects, which are more difficult to treat, and the cause of the disease is not easy to be removed, and the rate of eradication is very small. If children are diagnosed with nephrotic syndrome, they should actively cooperate with doctors for treatment, and active treatment can improve the cure rate.
