目得：为了评估多排CT尿路造影检测尿路abnormalities.MATERIALS和METHODS：65例泌尿科服务，其中尿路异常是强烈怀疑，进行了多排CT尿路造影。该技术包括通过腹部和骨盆的非增强、肾造影、压迫和排泄期图像。由两名放射科医生之一审查横向图像和三维重建。结果：多排CT尿路造影描绘了许多临床诊断的尿路异常，包括15 16尿路上皮恶性肿瘤，5先天性异常，5尿路结石，18肾盏和/或乳头状，30肾盂和/或输尿管，和25膀胱异常。所有异常均在横断面图像上检出。这些异常包括弥漫性尿路上皮壁增厚4例（其中3例患有移行细胞癌）肾脓肿、结肠膀胱瘘和偶然发现的肾外疾病（肝脏肿块、肝转移、淋巴结转移、主动脉夹层和嗜铬细胞瘤;这些发现各见于一名患者）。多排螺旋CT尿路造影是一种有用的方法来检测尿路异常。
PURPOSE: To evaluate multi-detector row computed tomographic (CT) urography for detection of urinary tract abnormalities.MATERIALS AND METHODS: Sixty-five patients referred from the urology service, in whom urinary tract abnormalities were strongly suspected, underwent multi-detector row CT urography. The technique included unenhanced, nephrographic, compression, and excretory-phase images through the abdomen and pelvis. Transverse images and three-dimensional reformations were reviewed by one of two radiologists. Findings were retrospectively compared with results of urinalysis, cystoscopy and/or ureteroscopy, and/or surgery.RESULTS: Multi-detector row CT urography depicted many clinically diagnosed urinary tract abnormalities, including 15 of 16 uroepithelial malignancies, five congenital anomalies, five urinary tract calculi, and 18 calyceal and/or papillary, 30 renal pelvic and/or ureteral, and 25 bladder abnormalities. All abnormalities were detected on transverse images. These abnormalities included diffuse urothelial wall thickening in four patients (three of whom had transitional cell carcinoma) a renal, abscess, a colovesical fistula, and incidentally detected extrarenal disease (a liver mass, hepatic metastases, lymph node metastases, an aortic dissection, and a pheochromocytoma; each of these findings was seen in one patient).CONCLUSION: Multi-detector row CT urography is a useful method for detecting urinary tract abnormalities.
