The presence of leukocytes (++) in urine routine is firstly considered as a manifestation of urinary tract infection, which may be caused by sedentary, urine holding, spicy stimulation of diet and unclean sexual contact. It is best to further check urine culture to clarify the type of pathogenic microorganisms and drug sensitivity, and then select some antibiotics, such as levofloxacin tablets, furantoin tablets, amoxicillin capsules and cefuroxime tablets. Continuous oral treatment for 7-10 days will cure the urinary tract infection. If the urinary tract infection is ruled out through the examination, elevated white blood cells in the urine routine may also be caused by bladder mucosal lesions, which need to be further examined by cystoscopy to clarify, and if it is indeed a bladder mucosal lesion, it needs to be treated by transurethral bladder mucosal electrodesis to cure completely. At the same time, during the treatment period, you should avoid spicy and stimulating diet, do not drink alcohol and do not eat seafood.
