An elevated white blood cell count through a urine test suggests an inflammatory infection of the urinary system. There are more causes of urinary tract infections. When an infection occurs, pathogenic bacteria invade the urinary tract epithelium, and immune cells mobilize leukocytes to the site of infection to devour the infecting bacteria, and an elevated number of leukocytes in the urine is seen. In case of urethritis, cystitis, pyelonephritis, elevated leukocytes, urinary stones, urinary tumors, and urinary tuberculosis in the urinary tract can lead to elevated urinary leukocytes. Elevated urine leukocytes should be treated promptly by seeking medical attention to identify the cause and then treat the cause. For simple urinary tract infections, oral antibiotics such as levofloxacin hydrochloride tablets and feverfew granules can be taken.
