Abstract

For two decades, computed tomography (CT) has challenged intravenous urography (IVU) in the evaluation of urinary tract abnormalities. Compared with IVU, CT is more sensitive and specific in the detection and characterization of a variety of urinary tract disorders, including renal masses and urolithiasis. The last purported advantage of IVU has been its ability to depict subtle and mucosal abnormalities of the urothelium. Now, using multidetector CT (MDCT), this challenge has been overcome. In this article, we review the current role of MDCT urography in the evaluation of the urinary tract.

摘要

二十年来，计算机断层扫描（CT）在评估尿路异常方面对静脉尿路造影（IVU）构成了挑战。与IVU相比，CT在检测和鉴别包括肾肿块和尿路结石在内的各种尿路疾病方面更敏感、更具特异性。IVU最后一个所谓的优势是其能够显示尿路上皮的细微和黏膜异常。现在，通过使用多排探测器CT（MDCT），这一挑战已被克服。在本文中，我们回顾了MDCT尿路造影在尿路评估中的当前作用。
