Urine protein exceeds the standard: urine protein is clinically and medically manifested as increased foam in the urine that does not dissipate over time. Normal people also have a small amount of protein in their urine, but if the increase of protein in urine is typical of proteinuria, it means that the patient’s kidneys, need to understand their condition and treat the cause to prevent the condition from continuing to deteriorate to bring more harm to the body, and urine protein can also cause damage to the kidneys. So what are the causes of excessive urine protein? 1, the renal tubular recovery of filtered protein is impaired, common diseases: tubulointerstitial lesions, pyelonephritis, congenital tubulopathy, hypokalemic nephropathy, etc. Common diseases of secretory and tissue proteinuria: such as Tamm-Horsfall protein secreted by the ascending branches of medullary collaterals, IgA in kidney and urinary tract infections, fibrin (original) and its degradation products in the urine in certain nephritis, complement components, glomerular basement membrane components, etc. can be excreted from the urine and cause proteinuria. The protein excreted in the urine is mixed into the urine and is excreted from the urine. 2. Overflow proteinuria, common diseases: seen in patients with multiple myeloma (with native – circumferential protein in the urine), myoglobinuria in severe crush injuries, lysozyme urine in myeloma and monocytic leukemia, etc. The characteristics of this type of proteinuria are: (1) the presence of a primary disease causing abnormal plasma proteinemia; (2) the detection of extra protein by qualitative analysis of urine protein; and (3) normal glomerular function in the early stage. 3, due to reduced glomerular filtration membrane permeability, common diseases: primary or secondary glomerulonephritis such causes of protein urine leakage referred to as glomerular proteinuria, it is due to ischemia, poisoning, immunopathological damage destroyed the perfection of the filtration membrane; or due to the weakened role of the filtration membrane charge barrier. The above is the introduction of urinary protein overload. Kidney disease brings great harm to your health, but as long as you keep a good attitude, choose the right treatment and actively cooperate with the doctor, there is a great hope to achieve the clinical cure effect. Active treatment is for your health, is the earnest hope of your family.
