Acute Renal Colic from Ureteral Calculus

Abstract
A 39-year-old man reports an eight-hour history of colicky pain in the right lower quadrant radiating to the tip of his penis. He had previously had a kidney stone, which passed spontaneously. Examination shows he has tenderness of the right costovertebral angle and right lower quadrant. Urinalysis shows microhematuria. Helical computed tomography shows a 6-mm calculus of the right distal ureter and mild hydroureteronephrosis. How should this patient be treated?
