Most kidney stones eventually pass through the urinary tract on their own within 48 hours, with ample fluid intake. Ketorolac (Toradol), an injectable anti-inflammatory drug, and narcotics may be used for pain control when over-the-counter pain control medications are not effective.hese drugs may be prescribed to some people who have stones that do not rapidly pass through the urinary tract. For kidney stones that do not pass on their own, a procedure called lithotripsy is often used.
