Contrast-enhanced voiding urosonography (ceVUS) is a dynamic imaging technique that makes it possible to study the structure of the urinary tract after the administration of intravesical contrast material. Initially, ceVUS was indicated mainly to study vesicoureteral reflux (VUR); however, since the ability of ceVUS to depict the structure of the urethra was demonstrated in both sexes, ceVUS is now indicated for examination of the entire urinary tract. The main benefit of ceVUS is that it does not use ionizing radiation. In recent years, fundamental changes have occurred in the understanding of VUR. The lessening effect of VUR and the low rate of occurrence of urethral pathologic conditions have given rise to changes in the indications for tests for these conditions. In addition to being able to help confirm a diagnosis of VUR, the ceVUS technique can be used to depict obstructive and nonobstructive urethral pathologic conditions, as well as normal variants, on high-quality images. Furthermore, ceVUS enables real-time assessment of voiding function. For these reasons, ceVUS should be not only an alternative to voiding cystourethrography, but also the technique of choice for the study of the entire urinary tract in pediatric patients.

对比增强排尿超声检查（ceVUS）是一种动态成像技术，可在膀胱内注入对比剂后研究尿路结构。最初，ceVUS主要用于研究膀胱输尿管反流（VUR）；然而，由于已证实ceVUS能够描绘男女尿道的结构，目前ceVUS已用于整个尿路的检查。ceVUS的主要优点是不使用电离辐射。近年来，对VUR的认识发生了根本性变化。VUR的减轻作用以及尿道病理状况的低发生率导致了这些疾病检查指征的变化。除了能够帮助确诊VUR外，ceVUS技术还可用于在高质量图像上描绘梗阻性和非梗阻性尿道病理状况以及正常变异。此外，ceVUS能够实时评估排尿功能。基于这些原因，ceVUS不仅应作为排尿膀胱尿道造影的替代方法，而且应成为儿科患者整个尿路研究的首选技术。本文提供在线补充材料。RSNA，2017年。
