Urine routine squamous epithelial cells (+) is indicative of increased shedding of squamous epithelium, and there are more possible causes: first, if there is inflammation of the anterior urethra, it will cause there to be increased shedding of urinary squamous epithelium. Squamous epithelium is mainly distributed in the anterior urethra, and the epithelium of the posterior urethra and bladder and ureter is mostly columnar and migratory epithelium. Therefore, inflammation of the anterior urethra can lead to increased shedding of squamous epithelium, and there will be epithelial (+) in the urine, along with an increase in the number of white blood cells. Secondly, if there is a stone, it can cause an increase in urine squamous epithelial shedding, especially if the stone stays for a long time, such as bladder stones, urethral stones or kidney stones, the stone stays for a long time will lead to localized epithelial squamous epithelialization, which will cause an increase in squamous epithelial shedding, which needs to be excluded by ultrasound examination of the urinary system. If you have stones, except for squamous epithelium (+), usually accompanied by an increase in the number of red blood cells or with symptoms of back pain and abdominal pain. Third, strenuous exercise or trauma can cause urine squamous epithelium (+), this situation is mainly seen in male external genital injury or after excessive exercise, can cause a transient squamous epithelium increase, and has no practical significance.
