Positive leukocytes in the urine of women are usually not serious, but if the urine leukocytes appear three plus or four plus, it is a more serious situation, commonly in more serious urinary tract infection. Because the female urethra is relatively short, it is particularly easy for bacteria to retrograde infection leading to urinary tract infection, which is prone to frequent urination, urinary urgency, urinary pain symptoms. In addition, it can lead to inflammation of the bladder, resulting in bladder irritation signs, that is, frequent urination, urinary urgency, urinary pain, and also retrograde infection leading to pyelonephritis, resulting in inflammation of the kidneys, so be sure to pay attention to the appropriate amount of water, so that the body to form more urine can promote the role of flushing bacteria. You can take antibiotics appropriately, such as levofloxacin hydrochloride, two capsules at a time, twice a day, can be taken for about a week.
