A urinary tract infection (UTI) is an infection that occurs when germs (called bacteria) get into the urinary tract. When you have a UTI several times within a year, it's called a recurrent UTI.
UTIs are caused by bacteria that get into your urine and then travel to your bladder. Women who have UTIs that keep coming back (recur) may have inherited genes that make them more likely to get these infections. UTIs that recur in men can be a sign of prostate infection (prostatitis).
