排泄性腎盂撮影におけるConray-400の造影効果について (コンレイ400(特集))

Abstract

The excretory pyelography is one of the most important diagnostic procedures in urology and there are numerous contrast agents available for this purpose. We used Conray-400 (Daiichi Seiyaku Co.), one of such contrast media, in 90 cases of excretory pyelography and found it to be highly effective in producing pyelograms. The results of its use may be summarized as follows: 1) Satisfactory pyelograms were obtained in 78 % of the cases if films were exposed 5 minutes after injection of the drug. 2) Pyelograms taken at 15 minutes after its intravenous injection were good in 83% of the cases. The drug thus rendered it possible to make correct diagnosis through the reading of films in more than 80% of the cases. The drug has a salient advantage of being injected with ease because of its low viscosity despite its high iodine content. Moreover, its use was attended by adverse effects in only 3 of the 90 cases, which by no means were serious nor life-endangering.
