Answer A

An emergency on-table IVU will generally only tell you if there is a normally functioning contralateral kidney and is unlikely to provide reliable or adequate detail on the actual injury itself. Two mL/kg of an iodinated contrast agent such as Omnipaque should be administered as a rapid bolus via a large bore cannula, ideally in placed in the antecubital fossa. A single shot KUB X-ray is then obtained at 10 minutes.
