There are also many women who are infected with some types of vaginitis, because the vagina is very close to the urinary tract, if there is inflammation of the vagina, then it may also be infected to the urethra, so it will cause urinary tract infections. After the diagnosis of urinary tract infection, if there is vaginitis should also be treated at the same time to treat vaginal inflammation, if there is no vaginitis, anti-inflammatory treatment, usually oral anti-inflammatory drugs, about 3-7 days. At the same time in the medication should also be instructed to drink more water, do not hold urine, as soon as there is a desire to urinate as soon as possible to go to urinate. If after a period of treatment, the urinary tract infection did not improve, then we should rule out whether the infection has been upstream. Therefore, the ultrasound examination of the urinary tract should be carried out to see if there are any problems with the kidneys, ureters and bladder.
