The patient's urine protein is high, so it is necessary to further carry out 24-hour urine protein quantitative examination to clarify the leakage of 24-hour protein and further distinguish between functional proteinuria and pathological proteinuria. If it is functional proteinuria, it is generally mild and temporary benign proteinuria, and the urinary protein will disappear soon after the cause is removed. The 24-hour urine protein content is below 0.5g, and rarely exceeds1g. In this case, proteinuria does not need special treatment. If the patient's proteinuria persists and the 24-hour urine protein quantity gradually increases, it needs to be considered as pathological proteinuria, and the diseases that lead to proteinuria need to be further clarified. At this time, it is necessary to give the patient relevant blood tests, preliminarily screen for secondary factors, further perform renal biopsy and puncture, and make a clear pathological diagnosis. If the patient is a primary glomerular disease, and the pathological type is minimal lesion, membranous nephropathy, IgA nephropathy, mesangial proliferative glomerulonephritis or membranous proliferative glomerulonephritis, according to the different pathological types, immunosuppressive therapy such as hormone or hormone plus immunosuppressant is given. At the same time, symptomatic support treatments such as calcium supplementation, lipid regulation, ARB and ACEI drugs to lower blood pressure and reduce proteinuria were given. If the patient has secondary renal diseases, such as diabetes, diabetic nephropathy, hepatitis B-related renal damage, lupus nephritis, henoch-schonlein purpura renal damage, amyloidosis, multiple myeloma, the renal damage caused by these secondary factors needs active treatment to improve proteinuria.
