[Nephrangiotomography with iopamidol in renal insufficiency]

An account is given of a study of 118 patients, including 67 with renal failure of varying severity, examined nephrangiotomographically with the aid of both a non-ionic contrast medium (iopamidol) and a conventional medium (sodium diatrizoate and methylglucamine). It is shown that the advantages presented by rapid injection of the medium, and the obtaining of prompt vascular data, are accompanied by those offered by the non-ionic medium, since it induces reduced osmotic diuresis, which permits satisfactory visualisation of the excretory ducts, even in patients with very low glomerular filtration values.
