The urinary tract is divided into the upper and lower urinary tract and is composed of a series of organs and tubes that take urine out of the body: the upper urinary tract includes the kidneys and ureters the lower urinary tract includes the bladder, urethra, and prostate A UTI may affect any part of the urinary tract. However, infection typically occurs when bacteria enter the urinary tract through the urethra, which is the tube carrying urine from the kidneys to the bladder. If the infection starts in the urethra and bladder, it is usually not serious and clears up with treatment. However, if a UTI reaches the kidneys, it can be more serious. A person with an upper urinary tract infection may need to go to the hospital for treatment. (责任编辑：) |
