The diagnosis of medullary sponge kidney traditionally was established by means of intravenous pyelography. Beginning in the mid-1990s, intravenous pyelography rapidly was supplanted by computed axial tomography as the preferred imaging study for evaluating patients with renal stone disease. Conventional computed tomographic imaging has not been satisfactory for diagnosing medullary sponge kidney. The introduction of multidetector-row computed tomography in 1999 allowed radiologists to acquire images composed of elements allowing the creation of high-resolution 3-dimensional displays. Computed tomographic urography is an imaging technique that provides both cross-sectional displays and images of the contrast-filled renal collecting systems, ureters, and urinary bladder that are the equivalent of intravenous pyelography. We report a case of medullary sponge kidney diagnosed by means of 3-dimensional multidetector-row computed tomographic urography.
传统上，髓质海绵肾的诊断是通过静脉肾盂造影来确立的。从20世纪90年代中期开始，作为评估肾结石病患者的首选影像学检查，静脉肾盂造影迅速被计算机断层扫描所取代。传统的计算机断层扫描成像在诊断髓质海绵肾方面并不令人满意。1999年多排探测器计算机断层扫描的引入，使放射科医生能够获取由多个元素组成的图像，从而创建高分辨率的三维显示。计算机断层扫描尿路造影是一种成像技术，它既能提供横断面图像，又能提供充盈造影剂的肾集合系统、输尿管和膀胱的图像，其效果等同于静脉肾盂造影。我们报告一例通过三维多排探测器计算机断层扫描尿路造影诊断的髓质海绵肾病例。
