title: The normal IVU: a trap for the unwary.
abstract: Intravenous urography (IVU) is considered to be a reliable means of investigating the urinary tract for renal pathology. We present two cases of patients who were investigated for loin pains. In both patients the IVU appearances were normal but the final diagnosis, as obtained by ultrasound, was renal cell carcinoma of the upper pole of the right kidney.
