1, acute nephritis: the onset of the disease is rapid, the severity of the disease varies, most of the prognosis is good. With appropriate treatment, it usually heals within a few months to a year. There is proteinuria, hematuria, often edema, hypertension or transient renal insufficiency. 2.Acute nephritis: rapid onset, heavy disease and rapid development. Proteinuria, hematuria, tubuluria, and edema are all evident, and there may be hypertension, rapidly developing anemia, and hypoproteinemia. Renal function decreases progressively and oliguria or anuria occurs. 3. Chronic nephritis: slow onset, prolonged, sometimes mild, sometimes severe, progressive renal function decreases, anemia, retinopathy and uremia may appear at a later stage. There are different degrees of proteinuria, edema and hypertension and other manifestations, varying in severity. 4.Nephrotic syndrome: massive proteinuria (more than 3.5g/24h). Hypoproteinemia (plasma albumin <30g/L). Highly edematous, hyperlipidemia. Nephrotic syndrome is only a symptomatic diagnostic term and can be caused by a variety of diseases. 5. Occult glomerulonephritis: characterized by asymptomatic microscopic hematuria and a small amount of proteinuria and tubular urine, with no obvious clinical symptoms.
