The diagnostic criteria for glomerulonephritis are the presence of hematuria, proteinuria, edema, hypertension, and renal damage of varying degrees, except for hematuria and proteinuria caused by urinary tract diseases. Glomerulonephritis is a group of diseases with similar clinical manifestations, such as hematuria, proteinuria, edema, hypertension, and renal damage, but with different disease etiology, pathogenesis, pathological changes, and prognosis, and mainly involving bilateral glomeruli. Glomerulonephritis is considered after the exclusion of hematuria and proteinuria caused by urinary tract infections, urinary stones and other urinary tract diseases. Glomerulonephritis is categorized into primary glomerulonephritis, secondary glomerulonephritis and hereditary glomerulonephritis. Glomerulonephritis can be diagnosed according to clinical symptoms and relevant laboratory tests, but in order to clarify the specific pathologic type and guide the treatment and prognosis, renal puncture biopsy is necessary to clarify the specific pathologic type. It is recommended that the patient should go to the regular hospital in time, and under the guidance of professional doctors to clarify the diagnosis and active treatment.
