Voiding urosonography (VUS) has proved to be a reliable method for the study of vesicoureteric reflux (VUR). Early reports considered it inadequate for imaging the male urethra.
To determine the usefulness of contrast-enhanced VUS for the study of the urethra.
A total of 208 children aged 2 days to 10 years underwent VUS to confirm or exclude VUR for different reasons (n = 150) or for follow-up (n = 58). Patients with unconfirmed suspicion of VUR (99 boys and 51 girls) also underwent VUS for the study of the urethra. Examinations were performed using a harmonic imaging mode specific for contrast (Levovist) enhancement. We used a 6-4-MHz convex probe and a transperineal and/or a transpelvic approach.
The neck of the bladder and the entire urethra were visualized in all patients (n = 150). The male urethra was considered normal in 95 boys (95.95%). We diagnosed posterior urethral valves in two patients, diverticulum of the prostatic utricle in one, and diverticulum of the anterior urethra in one. All abnormal cases were confirmed using conventional voiding cystourethrography.
VUS can replace voiding cystourethrography as the method of choice for the initial study of suspected VUR in children.
排尿期超声检查（VUS）已被证明是研究膀胱输尿管反流（VUR）的可靠方法。早期报告认为它不足以对男性尿道进行成像。
确定对比增强VUS对尿道研究的实用性。
共有208名年龄在2天至10岁的儿童因不同原因（n = 150）接受VUS以确认或排除VUR，或进行随访（n = 58）。对未确诊但怀疑有VUR的患者（99名男孩和51名女孩）也进行VUS以研究尿道。检查采用特定的对比剂（声诺维）增强谐波成像模式。我们使用6 - 4MHz凸阵探头及经会阴和/或经盆腔途径。
所有患者（n = 150）均可见膀胱颈部及整个尿道。95名男孩（95.95%）的男性尿道被认为正常。我们诊断出2例后尿道瓣膜、1例前列腺囊憩室和1例前尿道憩室。所有异常病例均经传统排尿性膀胱尿道造影证实。
VUS可替代排尿性膀胱尿道造影，作为儿童疑似VUR初始研究的首选方法。
