Nephrotic syndrome is basically considered clinically cured when there is no relapse after 30 years of stopping medication, but regular renal function tests are still needed. The typical symptom of nephrotic syndrome is that the patient develops a large amount of proteinuria, which triggers a high degree of edema, hyperlipidemia or hypoproteinemia. In the drug treatment of nephrotic syndrome, glucocorticoid (such as prednisone acetate) and immunosuppressant (such as cyclophosphamide) are common choices, and generally need to be adhered to the medication in order to effectively protect the kidney function. If the condition of nephrotic syndrome is basically stabilized and there is no recurrence of the disease after 30 years of stopping the medication, it can be considered that the kidney function has basically returned to normal, and it can be regarded as clinically cured, and in general, there will not be any recurrence of the disease. However, regular kidney examination is still recommended. It is suggested that patients with nephrotic syndrome need to pay attention to their diet and have regular medical checkups after treatment or cure.
