High squamous epithelial cells are not necessarily a problem. Normal urine has very few epithelial cells from the epithelium of the detached ureteral bladder as well as the urethra. Usually this value is not very significant in urine, but if this value is particularly high, it is important to consider whether there is local inflammation or epithelial cell shedding caused by tumor invasion. However, in the diagnosis of inflammation or tumor, this result of the urine test alone cannot be relied upon, and the diagnosis cannot be established without other systemic symptoms or clinical indicators. Women have a special physiological structure, which means that the urethra and vagina are in close proximity to each other. Because of the close proximity of the two, vaginal secretions can easily enter the urine. And most of the vaginal secretions have epithelial cells, including squamous epithelial cells. So when you get a result that is high in squamous epithelial cells, you should pay attention to whether vaginal secretions are entering the urine. In this case, further clarification can be made by rechecking the urine routine and, if necessary, further improvement of the urinary tract and genital ultrasound to make a judgment on the current diagnosis.
