[Urography with non-ionic contrast media. Multicenter experience on the optimization of the technic]. / Urografia con mezzi di contrasto non ionici. Esperienza multicentrica sulla ottimizzazione della tecnica.

ABSTRACT

The authors report the results of a multicentric experience based on 1200 urograms performed with nonionic contrast medium. The global diagnostic reliability is evaluated, together with the specific reliability for kidneys, ureters, and bladder, according to the various pathologies. The eventual need of radiographs of completion is showed. In searching for an optimization of the technique for nonionic contrast medium, a panoramic radiograph performed 10' after the end of the injection is pointed out as the key-moment of the test, being extremely rich in information, so as to help defining the most appropriate technique to continue the examination. For its excellent tolerability and high reliability, the nonionic contrast medium is recommended also in routine IVP, not only in risk patients.
