PLAIN ABDOMINAL X-RAY VERSUS COMPUTERIZED TOMOGRAPHY SCREENING: SENSITIVITY FOR STONE LOCALIZATION AFTER NONENHANCED SPIRAL COMPUTERIZED TOMOGRAPHY

Abstract

Plain abdominal x-ray is more sensitive than scout CT for detecting radiopaque nephrolithiasis. Of the stones visible on plain abdominal x-ray 51% were not seen on CT. To facilitate outpatient clinic followup of patients with calculi plain abdominal x-ray should be performed when a stone is not clearly visible on scout CT.
