title: [Clinical studies with a new non-ionic contrast medium (iopamidol) in intravenous pyelography in aged patients].
abstract: Iopamidol (IOPAMIRON 300) was examined for excretory urography on 21 patients, between 70 and 94 years old, with reference to visualization, safety and urinary excretion. The results about visualization and safety were compared with those obtained with 60% Urografin. Iopamidol was demonstrated visualization nearly equivalent to that with Urografin, and 19% better pyelogram. Especially, calix showed a clearer contrast than those obtained with Urografin. None of the 21 old patients experienced any side effects or adverse reactions. No abnormalities were noted in serum chemistries. Iopamidol was not quickly excreted into the urine, only 19% during the first 2 hours, in elder patients.
