If there is occult blood in the urine examination, the treatment should be: first, further ultrasound examination of the urinary system to find out whether there are stones, tumors, polyps and other lesions in the urinary tract. Second, if the ultrasound examination reveals the presence of stones, it is recommended to choose extracorporeal shock wave lithotripsy or surgery according to the size and location of the stones. Thirdly, if the ultrasound examination reveals a suspected tumor of the urinary system, further CT examination of the urinary system is required, and after the CT examination confirms the location of the tumor, open surgery or transurethral lumpectomy can be chosen to remove the tumor according to its size and location. Fourthly, if ultrasound and CT examination are normal and urine routine examination indicates infection, anti-infection treatment is needed. You can take one capsule of levofloxacin hydrochloride orally three times a day for one week, and then recheck the urine routine to see if the occult blood disappears.
