This study's aim is to present the specific ultrasonography (US) findings of a series of urachus anomalies.
Seven patients with suspected urachal anomalies underwent US scanning initially prior to the surgery and the features of images were reviewed respectively. The clinical data and pathologic results were collected also.
US successfully diagnosed urachal anomalies in 5 patients (5/7, 71.4%) and failed to diagnose in 2 patients (2/7, 28.6%). Patent urachus showed a tubule between the umbilicus and bladder; urachal sinus was a blind focal dilatation at the umbilical end, while vesicourachal diverticulum was an outpouching at the vesical end and urachal cyst was identified as an anechoic structure along the urachus. Non-enhancement in the base and centre was the distinct features of urachus carcinoma by contrastenhanced ultrasonography (CEUS). Using a high frequency probe and CEUS the diagnostic ability of US may be improved.
US showed good diagnostic ability in urachal anomalies and combined with CEUS could improve the differential diagnosis.
本研究旨在呈现一系列脐尿管异常的特定超声检查（US）结果。
7例疑似脐尿管异常的患者在手术前首先接受了超声扫描，并分别对图像特征进行了回顾。同时收集了临床资料和病理结果。
超声成功诊断出5例脐尿管异常患者（5/7，71.4%），2例诊断失败（2/7，28.6%）。脐尿管未闭表现为脐与膀胱之间的管状结构；脐尿管窦是脐端的局限性盲端扩张，膀胱脐尿管憩室是膀胱端的囊袋样突出，脐尿管囊肿表现为沿脐尿管走行的无回声结构。超声造影（CEUS）显示脐尿管癌的特征为基底部和中心无强化。使用高频探头和CEUS可提高超声的诊断能力。
超声在脐尿管异常中显示出良好的诊断能力，结合CEUS可改善鉴别诊断。
