Squamous epithelium, a type of epithelial cell tissue. Epithelial tissue is an important structure that lines or covers other tissues. It is composed of dense epithelial cells and a small amount of intercellular stroma. The structure is characterized by tightly bound cells and little intercellular stroma. It usually has protective, absorptive, secretory, and excretory functions. In the human urinary tract, the surfaces of the renal pelvis, ureter, bladder and urethra are covered with squamous epithelial cells. When the tissue is damaged, it will lead to the shedding of squamous epithelium, and the urinary routine will suggest elevated squamous epithelium. The actual significance of this indicator for clinical diagnosis is not great. If there is elevated squamous epithelium, you can first drink more water, urinate more often and dilute the urine to observe for a period of time and then recheck the urine routine, if it is accompanied by elevated white blood cells in the urine, it is recommended to use antibiotics to treat for a period of time. In summary, the main reason for elevated squamous epithelium in urine routine is inflammation of the urinary system, which is of little practical significance and need not be a cause for concern.
