A urine leukocyte of 1+ suggests a mild urinary tract infection, which is usually not serious. At this time, the next step of treatment should be decided according to the patient’s specific situation. If the patient does not have any symptoms of urinary discomfort, but only found urine leukocytes 1+ during the physical examination, we suggest the patient to review the urine routine, if the urine routine turns out to be (-), you can hold off on treatment for now. Drink more water and pay attention to the observation. If the patient is still urine leukocyte 1+ on recheck, it can be diagnosed as urinary tract infection, and some patients may also have symptoms such as urinary frequency, urinary urgency and urinary pain. In this case, you can follow the doctor’s prescription to apply antibiotics for treatment, commonly used antibiotics for quinolones, such as levofloxacin. This is because quinolone antibiotics are highly effective and low toxicity, and they are more effective in the treatment of urinary tract infections. However, if the patient is under 18 years old, or if the woman is in the stage of pregnancy or breastfeeding and has no history of drug allergy, she can be treated with oral cephalosporin antibiotics as prescribed by the doctor. In addition, you can also use Chinese patent medicines that relieve heat and promote lymphatic flow, such as retention of urine tablets and Bazheng capsule, which are more effective for urinary tract infections.
