コンレイ400による腎盂造影の経験

Abstract

Conray 400 was examined as to its contrast ability and side effects on 67 excretory pyelographies with intravenous injection of 40 ml, and the following results were obtained. Diagnostic pyelograms were observed in 125 out of 132 kidneys (94.7%). In 58.3%, more than one third of the whole length of the ureter or the ureter above the obstruction was also clearly visualized. And in 55 out of 67 cases (82.1%), it was possible to make diagnosis without other urographies. Side effects were observed in 44.8%, among which pain in the blood vessel was most frequent. All of them, however, were slight and serious side effects were not experienced. Characteristically, Conray 400 is easy to inject intravenously owing to the low viscosity, hax excellent contrast ability and gives clear and detailed image. It was emphasized that the pre-treatment of intestines was almost not required for 40 ml-injection method and that Conray 400 was easy to inject, giving a natural image of the urinary tract without need of a pressure bandage over the ureter.
