摘要
目的探讨多排螺旋CT泌尿系成像(spiralCTurography,SCTU)对输尿管病变的诊断价值。方法35例输尿管病变患者,其中结石18例、肿瘤3例、息肉1例、畸形4例、炎症4例、输尿管瘘2例、腹腔内肿瘤手术后遗症3例。均作螺旋CT泌尿系检查,先作平扫,然后注射对比剂后10～15min行螺旋CT容积扫描,在工作站进行图像后处理。其中22例行静脉泌尿系造影。结果在SCTU图像上,18例,21枚结石(其中2枚阴性结石)可清晰发现结石及扩张的输尿管和肾盂;3例肿瘤可见输尿管腔突然中断及肿块;4例双肾盂并双输尿管畸形均见两个肾盂和两条输尿管;2例输尿管瘘显示瘘口的位置及走行。结论与普通CT及静脉尿路造影(IVU)相比,螺旋CT及其SCTU技术有明显的优越性,能提高输尿管病变诊断的准确率。
Objective To studythe diagnostic value of spiral CT urography（SCTU） in ureteral diseases. Methods Spiral CT urography（SCTU） was performed in 35 cases with ureteral diseases, including 18 cases of ureteral calculus, 3 carcinomas, 1 polyp, 4 malformations,4 inflammations, 2 ureteral fistulas and 3 operating sequelas. In 35 cases, 22 also received intravenous urography（IVU）. Results On SCTU, the location and diameter of 21 ureteral calculus（19 radiopaque, 2 radiolucent） and enlargement of renal pelvis and ureter were displayed local rarefication obstruction of contrast medium in ureter were detected in 3 tumor. 4 malformation with double renel pelvis and utter were demonstrated.The location and direction of 2 ureteral fistulas were notified. Conclusion SCTU is superiord to IVU and conventional CT in improving diagnostic accuracy of ureteral disease.
