The aim of this study was to report our experience with transperineal ultrasound in studying the urethra, as a complementary technique to contrast-enhanced voiding urosonography (VUS). The VUS was performed in 350 patients (244 males, 106 females) less than 4 years of age, and complemented with perineal US. Ultrasound of the kidneys and bladder was obtained before and during bladder filling and post-voiding. The urethra and the neck of the bladder were evaluated sagittally by transperineal ultrasound (5-7.5 MHz) before, during, and after voiding. Only cases of posterior urethral valves diagnosed at VUS were followed by voiding cystourethrography (VCUG), which was performed on a different day. A satisfactory evaluation of the urethra was obtained in 332 cases (94.86%): (a). normal urethra ( n=328); and (b). posterior urethral valves ( n=4). In the latter 4 cases there was concordance between results at VUS and VCUG. Eighteen cases (5.14%) were excluded from the study because the quality of the examination was suboptimal. Transperineal US offers an initial imaging modality for studying urethral pathology and thus may complement VUS.
本研究的目的是报告我们使用经会阴超声研究尿道的经验，作为对增强型排尿超声检查（VUS）的一种补充技术。对350例年龄小于4岁的患者（244例男性，106例女性）进行了VUS检查，并辅以会阴超声检查。在膀胱充盈前、充盈期间和排尿后获取肾脏和膀胱的超声图像。在排尿前、排尿期间和排尿后，通过经会阴超声（5-7.5MHz）矢状面评估尿道和膀胱颈。只有在VUS检查中诊断为后尿道瓣膜的病例才在不同日期进行排尿性膀胱尿道造影（VCUG）。332例（94.86%）患者获得了对尿道的满意评估：（a）正常尿道（n=328）；（b）后尿道瓣膜（n=4）。在这4例后者中，VUS和VCUG的结果一致。18例（5.14%）患者因检查质量欠佳而被排除在研究之外。经会阴超声为研究尿道病变提供了一种初步的成像方式，因此可以补充VUS检查。
