新造影剤Umbradil及びUmbradil Viscous Uの使用経験

Abstract

Reports were made of experiences with a new co n trast agent, Umbradil and Umbradil Viscous U of Messrs, Astra, Sweden. 1) Excretory pyelography was carried out using Umbradil 35 % in 7, 50 % in 8, and 70 % in 2 cases, totaling 17 cases. Satisfactory pictures were obtained in all cases within 7 to 15 minutes after initiatation of the injection. Urograms were taken without urete r al compression in 5 patients, which procedures generally resulted in an insufficient filling of the agent and afforded unclear shadows, as compared with those cases where an ureteral compresser band was used . Then the shadows obtained were found unclear in 2 cases where a 70 % Umbradil was employed, too. Side reactions were slight, only a transient nausea and feverish sensation being experienced in 2 patients, respectively. 2) Umbradil 70 % w a s employed for translumbar abdominal aortography in 10 cases and for seriography in 3 of the 10 cases . With both procedures were obtained quite satisfactory arteriogram. sIn 1 patient with Goldblatt's hypertension a sense of oppression of the chest was induced and in 1 patient was encountered an incidence of nausea , but no side reactions other than the above were produced . 3) Umbradil 70 % was used for abdominal venography via femo ral vein in 2 cases. 4) Umbradil Viscous U was used for urethrography in 21 male patients. In al l cases, the posterior urethra was conspicuously distended , the region of seminal colliculus and the neck of bladder being clearly represented . There was a marked difference in the pictu r es obtai ned between Umbradil Viscous U and NaI 20 % employed as the control, namely the former being of satisfaction as a urethrographic contrast medium in that it is highly viscous and non-irritating. 5) Umbradil Viscous U was employed for urethrography in 11 female patients, the picture of urethral diverticulum being given in 3 of the 11 patients. It is therf ore satisfactory as a medium for urethrography in the female, too.
