Clinical classification of latent glomerulonephritis type

　　1. Asymptomatic hematuria urine only hematuria, no proteinuria, most of the deformation of red blood cells in urine red blood cell. Generally microscopic hematuria, showed a persistent or recurrent nature. Some patients with strenuous exercise, fever, etc. can occur when a transient gross hematuria, and in a short time away. Sometimes unconventional normal. More common in children and young people. Laboratory blood test, ESR, platelets, the clotting time, liver and kidney functions were normal. Pathological changes are mainly IgA nephropathy, and other pathological types of non-IgA mesangial proliferative glomerulonephritis, focal glomerulonephritis, thin basement membrane nephropathy.
　　2. Asymptomatic hematuria and proteinuria associated with clinical manifestations of hematuria proteinuria, is common in progressive glomerular disease, can be found in a variety of primary glomerular disease. Such as glomerular minimal change, mild mesangial proliferative glomerulonephritis, focal proliferative glomerulonephritis, IgA nephropathy, and even in early membranous nephropathy. Clinically, hypertension, edema, renal dysfunction performance, easy to misdiagnosis.
　　3. Asymptomatic proteinuria more common in young men, showed persistent proteinuria, urinary protein normally 2g / d less, mainly to albumin. Urine normal, no edema, high blood pressure of clinical manifestations, renal function and other biochemical tests were normal. No pathological lesions may also occur in different types of glomerular diseases such as membranous nephropathy, mesangial proliferative glomerulonephritis, minimal change nephropathy, focal segmental glomerular sclerosis, and even some of the IgA early nephropathy.
