[Evaluation of clinical tolerability and diagnostic efficacy of ioversol 350 in UIV. A randomized double-blind study of ioversol 350 versus iohexol 350].

The authors evaluated the clinical safety and the efficacy of ioversol compared to the reference contrast medium iohexol, during IVP. The clinical safety has been evaluated by the occurrence of side-effects. The efficacy was appreciated in terms of insufficient, medium, good or excellent. No side-effect was recorded for both contrast media. There was no difference in opacification quality and efficacy between ioversol and iohexol. The authors conclude that ioversol is a safe and effective contrast medium which can be, therefore, particularly recommended for urographic examinations of high risk patients.
