<s>[INST] Treatment [/INST] There are two types of UTIs: simple and complicated. Simple UTIs are infections that happen in healthy people with normal urinary tracts. Complicated UTIs happen in abnormal urinary tracts or when most antibiotics cannot treat the bacteria causing the infection. Most women have simple UTIs, while the UTIs in men and children should be th ought of as complicated.  
A simple UTI can be treated with a short course of antibiotic meds. A short, 3-day course of an appropriate antibiotic will often treat most uncomplicated UTIs. However, some infections may need to be treated longer. Pain and the urge to urinate often go away after a few doses, but you should still take the full course of the antibiotic to ensure all the UTI is treated, even if you feel better. Unless UTIs are fully treated, they can return. You should also drink plenty of liquids, especially around the time of a UTI. Postmenopausal women with UTIs may be helped by topical (vaginal) hormone replacement with estrogen. Since some patients may have other medical issues that prevent them from using estrogen, you should talk with your health care provider before starting any treatment.If the UTI is a complicated UTI, then a longer course of antibiotics is given. Sometimes the antibiotic therapy may be started intravenously (IV) in the hospital. After a short period of IV antibiotics, the antibiotics are given by mouth for up to 2 weeks. Kidney infections are often treated as a complicated UTI. Source: Urology Care Foundation. Link: https://www.urologyhealth.org/urology-a-z/u/urinary-tract-infections-in-adults. Field: Urology.
