Urine culture plus drug sensitivity is a common clinical test that allows the patient to clean the urethral orifice and its surrounding area as well as the vulva, and then keep the urine in a sterile clean vial and send it to the laboratory for culture to observe whether there is bacterial growth and what kind of bacterial infection is present, and which antibiotics are effective for treatment, which can accurately diagnose and treat urinary tract infections and significantly improve the efficacy. Therefore, patients who are clinically suspected of having urinary tract infections, especially those with poor treatment and recurrent urinary tract infections, should have a urine culture plus drug sensitivity test. In addition, urine culture is often required for kidney and ureteral stones, which are common in urology, before surgery with minimally invasive treatment, and must be negative before surgery to prevent aggravation and spread of infection.
