Urine protein and urine leukocytes are two very different substances. In most cases, urine protein is caused by various types of nephritis, from which protein is lost due to damage to the permeability of the glomerular filtration membrane, and can be detected in the urine routine. After urinary tract infection, the body will gather white blood cells in the urinary tract to destroy the inflammation, which can be detected in the urine routine. When patients have urine protein, many times they need to apply hormones to treat it, which can repair the glomerular filtration membrane and prevent further damage and further loss of urine protein. And when white blood cells appear in the urine, it indicates a urinary tract infection, which needs to be treated with antibiotics against infection. When the inflammation is controlled, the white blood cells in the urine will naturally disappear. However, if urine protein and white blood cells are found at the same time in urine routine, it cannot be thought that nephritis and urinary tract infection exist at the same time, and it is possible that the urine protein is positive due to urinary tract infection.
