Urine routine bacteria, epithelial cells, white blood cells are high generally due to bacterial infections caused by urethritis, vaginitis and other genitourinary infections. Normal people will not excrete bacteria in the urine, the presence of bacteria in the urine routine generally suggests that the genitourinary system has a bacterial infection. Inflammation of the urinary system will cause elevated white blood cells, and pus cells will appear in severe cases. Epithelial cells in urine generally originate from the epithelial tissues of the renal tubules and various parts of the urinary tract. If squamous epithelial cells are elevated, women may be associated with gynecological inflammation such as vaginitis and contamination during urine collection; increased renal tubular epithelial cells may be associated with pyelonephritis and so on; increased migratory epithelial cells are generally associated with inflammation of the renal pelvis, inflammation of the bladder triangle, inflammation of the ureter, and so on. When the urine routine bacteria, epithelial cells and white blood cells are all high, it is necessary to clarify the site of inflammation under the guidance of the doctor and actively treat it.
