Iga nephropathy patients may be occult nephritis, due to the physical examination of urine, hematuria, proteinuria, or because of edema, hypertension to the hospital, the test of hematuria, proteinuria. In this case, hematuria mostly belongs to glomerular hematuria. The urinary red blood cell phase is more than 70%, and the abnormal red blood cell is more than 5%. This is the diagnostic standard of glomerular hematuria. To further improve the renal biopsy, immunofluorescence showed that iga or iga based immune complexes were deposited in the glomerular mesangial area, which is the gold indicator for diagnosis of iga nephropathy. The diagnosis of iga nephropathy clearly indicates that further treatment is based on the patient's blood pressure level, the degree of proteinuria and the degree of chronic renal pathology. The main goal of treatment is to control the patient's blood pressure to reach the standard, and strive for less than 130/80 mm Hg, or even less than 125/75 mm Hg. In addition, try to reduce urinary protein as much as possible, and strive for qualitative negative, quantitative less than 0.3g/24h.
