An uncomplicated urinary tract infection (UTI) is a bladder infection (cystitis) or
kidney infection (pyelonephritis) that is not caused by a
structural problem, obstruction within the urinary tract (such as a
kidney stone or an
enlarged prostate), or other medical condition that
affects kidney and bladder function, such as
diabetes. Uncomplicated UTIs primarily affect young
and middle-aged women before menopause.
