摘要： 膀胱癌是全球第九大癌症，也是我国最常见的泌尿系统恶性肿瘤。膀胱癌起源于膀胱黏膜上皮，恶性程度高、易复发，以尿路上皮癌最为多见。膀胱良性肿瘤较少见，早期手术治疗效果好。膀胱肿瘤治疗方案的选择和患者的预后取决于肿瘤的早期发现和正确诊断。超声造影（contrast-enhanced ultrasound，CEUS）是一种实时动态显示微循环的影像学检查技术，具有安全性好、操作相对简便、可重复进行的优点。此技术在膀胱肿瘤的鉴别诊断以及膀胱癌的分期、分级评估中发挥越来越重要的作用。该文就CEUS应用于诊断膀胱肿瘤的研究进展进行综述。

Abstract:
Bladder cancer is the ninth leading cancer in the world, and the most common malignant tumor in urinary system in China. Bladder cancer is originated from mucosal epithelium of the bladder, has a high degree of malignancy and is easy to relapse. Urothelial carcinoma is the most common type. Benign bladder tumor is rare, and surgical removal yields better results. The optimal treatment and patients' prognosis of bladder tumor are attributed to its early detection and accurate diagnosis. Contrast-enhanced ultrasound (CEUS) is a new imaging technique which could dynamically display the microcirculation of tumors and tissues. The advantage of CEUS is good safety, easy manipulation, and repeatable use. CEUS is now playing a more and more significant role in diagnosing bladder tumors. In this article, the application of CEUS to the diagnosis of benign and malignant bladder tumors is reviewed.
Key words: contrast-enhanced ultrasound (CEUS), bladder tumor, differential diagnosis, benign lesion, urothelial carcinoma
