Clinical experience with iohexol versus iopromide in excretory urography.

Abstract

In a controlled double-blind study the quality of the contrast produced by iopromide and iohexol was compared in two groups of 100 patients by excretory urography. The aim was to investigate whether iopromide or iohexol has any diagnostic advantages for the opacification of the kidneys, the renal pelves, and the ureters. The results show that there is no difference in contrast quality between the two substances (chi-square, p greater than 0.1). Moreover there is no difference in the frequency of concomitant symptoms (chi-square, p greater than 0.1). Both contrast media show the well-known excellent tolerance with only 1% side effects and the good contrast quality of the nonionic contrast media.
