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
