To determine: 1) whether a simple clinical prediction rule could identify emergency department patients with ureteral calculi; 2) whether the kidney, ureter, and bladder (KUB) radiograph provides diagnostic information beyond that obtained from the history and physical examination; and 3) whether ureteral calculi can be diagnosed accurately in the emergency department without emergency excretory urography, commonly known as intravenous pyelography (IVP). ⋯ These findings, which should be confirmed in another emergency department, suggest that subsets of patients with suspected ureteral calculi may be managed without emergency IVP; this approach thereby reduces the time a patient spends in the emergency department, radiation exposure, expense, and morbidity.
