Common pathological types of nephrotic syndrome
1 small lesions: the pathological type of the patients under light microscope, the normal glomerulus, and occasionally see epithelial swelling, micro immunoglobulin and complement C3 deposition.
2 mesangial proliferative glomerulonephritis: under the light microscope, glomerular mesangial cells were proliferated in the pathological type, and the number of mesangial cells was more than 3. Interstitial inflammatory cell infiltration and fibrosis, renal tubular atrophy, renal vascular normal.
3 focal segmental glomerulosclerosis: Patients with this type of pathology are characterized by glomerular damage that affects a small number of glomeruli and glomeruli. Starting from the juxtamedullary glomeruli involved, may only involve a number of glomerular capillary loops, severe glomerular lesions were most affected, no cells or cells are hyaline degeneration of uniform material, see serious balloon adhesion.
4 proliferative glomerulonephritis: mesangial capillary nephritis. The pathological changes in mesangial cell proliferation, capillary basement membrane thickening and the two main features.
5.IgA nephropathy: IgA nephropathy histology can be pided into 5 levels, namely the grade II lesions with mild damage; with a small amount of segmental proliferation; III focal segmental glomerulonephritis; IV diffuse mesangial proliferation with damage and hardening; V-grade diffuse sclerosing glomerulonephritis involving 80% in glomerular.
