逆行性腎盂撮影に対するSodium iothalamate 66.8%(Conray 400)の使用経験 (コンレイ400(特集))

Abstract

1.In an attempt to study its usefulness as a contrast medium for retrograde pyelography, a 2-fold dilution (33.4%) of sodium. iothalamate 66.8% (Conray 400) was used in 23 cases and the results were compared with those with 38% Urografin. The test medium was demonstrated to be not inferior to Urografin in its capacity of visualizing the renal pelvis. 2. In 20 (87%) out of the entire 23 cases the contrast medium gave a clear-cut pyelogram with no blurring of the picture which makes the film incompetent for diagnostic purpose as seen in any instances. 3. As compared to Urografin which was administered contra laterally, Conray 400 was found to be more excellent in 13% and equally satisfactory in 78.3% in its visualization. 4. No adverse reactions worthy of mention was noted. 5. An experiment on the rate of injection confirmed that Conray 400, being lower in viscosity, is far easier to inject than Urografin.
