Positive urine occult blood, the first thing to identify what disease the blood is caused by, according to the cause to treat. If urine occult blood is combined with symptoms of frequent urination, urinary urgency and painful urination, it is generally considered to be caused by infection and treated with antibiotics, the most commonly used cephalosporin antibiotics and macrolide antibiotics, such as azithromycin and roxithromycin, can be used. If the urinary occult blood is caused by obvious trauma to the urinary tract, it is usually cured by using hemostatic drugs and the patient resting in bed as much as possible. If urinary occult blood is combined with back pain, it is most often a symptom of urinary stones. Depending on the size of the stones, it is decided whether to do extracorporeal shock wave lithotripsy, or intracavitary lithotripsy to clear the stones, which may require surgery. In addition, if there are no symptoms of hematuria, it is likely to be a bladder tumor or urinary tract tumor, and a cystoscopy is needed as soon as possible.
