Iohexol has a slightly higher osmolarity in comparison with iopamidol; therefore it might induce a more pronounced diuretic effect and then a better distension of the excretory pathway. A trial was carried out in two groups of 50 patients with normal renal function who underwent urography, namely with 50 ml (15 gI) of iopamidol and of iohexol. No significant differences in the evaluated parameters (nephrography, calyces, pelvis, ureters and bladder) have been found. Both contrast media allowed to perform good quality urographies.
与碘帕醇相比，碘海醇的渗透压略高；因此，它可能会产生更明显的利尿作用，进而更好地扩张排泄途径。对两组各50例肾功能正常且接受尿路造影的患者进行了一项试验，分别给予50毫升（15克碘）的碘帕醇和碘海醇。在评估参数（肾造影、肾盏、肾盂、输尿管和膀胱）方面未发现显著差异。两种造影剂都能进行高质量的尿路造影。
