What is a urinary tract infection?

A urinary tract infection or UTI is an infection (due to bacteria, parasites or fungi) of any of the urinary tract structures that include the bladder, urethra, ureters or kidneys.

However, when UTI is diagnosed most physicians are referring to a bladder infection otherwise known as cystitis. A urethral infection is urethritis, ureter infection is what it is, and kidney infection is pyelonephritis.

A urinary tract infection (UTI) occurs when bacteria invade any part of the urinary tract, particularly the urethra or urinary bladder. Bladder infections, also called cystitis, are very common in women because of their anatomy. In fact, 10 to 20 percent of all women have urinary tract discomfort at least once a year. In turn, men do not commonly get UTIs unless they have enlarged prostates. Recurrent UTIs are a significant problem and can cause progressive damage, resulting in scarring and, in rare cases, kidney failure.

A urinary tract infection is a general term for an infection anywhere between the kidneys and the urethra (where urine comes out). Most urinary tract infections are bladder infections. They often cause pain or burning when you urinate. They're caused by bacteria and can be cured with antibiotics.
