Dilatation of the pelvicalyceal system was documented in volunteers with healthy kidneys in whom renal excretation was increased by means of a variety of methods. As a rule, the proximal ureter is not visualised. In mild or moderate urinary obstruction, however, the ureter is almost always visible, and stasis is mostly unilateral. Although sonography is a method of good sensitivity, the excretory urogram remains an essential diagnostic tool in the examination of the pelvicalyceal and ureteral systems.
通过多种方法增加肾脏排泄功能时，对肾脏健康的志愿者进行了肾盂肾盏系统扩张的记录。通常情况下，近端输尿管无法显影。然而，在轻度或中度尿路梗阻时，输尿管几乎总是可见的，且淤滞大多为单侧性。尽管超声检查是一种敏感性良好的方法，但排泄性尿路造影仍然是检查肾盂肾盏和输尿管系统的重要诊断工具。
