Ultrasonography compared with intravenous urography in investigation of urinary tract infection in adults.

Abstract

Ultrasonography provides a safe and accurate method of imaging the urinary tract in adults with infection. Combined with a plain abdominal radiograph, it should replace urography as the initial imaging investigation in these patients. Major savings would result from adopting this policy, and the risks to patients from ionising radiation and intravenous contrast media would be appreciably reduced.
