Possible Stone?: If your UTI symptoms are mainly urgency and frequency of urination, there are many possible causes. Since the studies so far haven't shown a cause, i would lean toward overactive bladder or a stone in the ureter (kidney tube). A ct scan will detect stones. If negative, other causes of bladder irritation should be evaluated and a look in the bladder should be done by a urologist.
