MSCT非增强扫描在输尿管结石诊断中的应用(1)
摘 要：目的 分析输尿管结石的多排螺旋CT表现，评价MSCT在输尿管结石诊断中的应用价值。方法 收集我院2017年7月～2018年2月69例经手术确诊为输尿管结石患者的CT非增强扫描资料，观察结石在输尿管轴位、多平面重组和曲面重组图像上的表现，并与术中所见情况进行对比。结果 本组69例不同成份的输尿管结石CT值为126～138 HU，在CT图像上都被显示出来；且MSCT在输尿管结石的定位、定量诊断上与手术结果完全一致，诊断准确率达100.00%。结论 MSCT非增強扫描对不同成分的输尿管结石均敏感，结合其轴位、MPR和CPR三者图像诊断输尿管结石准确率极高。

Abstract：Objective To analyze the multi-slice spiral CT manifestations of the kidney and ureter calculi and evaluate the value of MSCT in the diagnosis of the kidney and ureter calculi.Methods From July 2017 to February 2018，the CT non-enhanced scanning data of 69 cases of kidney and ureter calculi diagnosed as ureteral calculi by surgical operation were collected，and we observed the performance of stones in the ureteral axial position，multiplanar recombination and surface recombination images，and compared with the intraoperative findings.Results The CT value of 69 cases of kidney and ureter calculi with different components ranged from 126 to 138 HU，which were displayed on CT images；And MSCT in the localization of ureteral calculi， quantitative diagnosis and surgical results are completely consistent，the diagnostic accuracy of 100.00%.Conclusion MSCT non-enhanced scanning is sensitive to different components of kidney and ureter calculi，combined with its axial position，MPR and CPR image diagnosis of kidney and ureter calculi is very accurate.

输尿管结石(kidney and ureter calculi)又称为上尿路结石，是临床常见的急腹症，患者以腰腹部疼痛伴或不伴向会阴部放射、血尿为主要症状，临床上结合症状、尿常规和影像学检查等作出明确诊断。输尿管结石梗阻产生输尿管近端和肾脏积水，肾脏肿大、肾周炎，尿液逆流入肾可引发感染，严重者可引起肾、输尿管破裂、肾功能丧失等并发症[1]。腹部尿路平片、超声和静脉尿路造影是泌尿系结石的传统检查方法，这些传统检查方法因患者肠内容物、肠气或者结石较小的影响而容易漏诊、误诊。近年来随着螺旋CT技术进步和广泛应用，为泌尿系结石诊断提供了更简单、可靠的方法，降低了误诊漏诊率。国外的不少医疗机构在泌尿系结石诊断中，已采用多排螺旋CT(MSCT)非增强扫描逐步取代传统的腹部尿路平片、超声和静脉尿路造影检查方法[2]。本文分析2017年7月～2018年2月经过螺旋CT非增强扫描确诊的69份输尿管结石病例相关资料，评价其在输尿管结石诊断中的应用价值。

1资料与方法
1.1一般资料 收集2017年7月～2018年2月广西龙州县人民医院门急诊考虑为泌尿系结石收治入院患者69例。其中男性40例，女性29例，年龄16～75岁，平均年龄(33.01±5.03)岁。其中42例因怀疑输尿管结石直接做腹部CT检查，其余27例因怀疑输尿管结石先做腹部B超、腹部尿路平片等检查未明确诊断，进而做腹部CT检查。
1.2方法 所有患者都使用CT机进行泌尿系检查，扫描范围从肾上极到耻骨离合下缘。采用SIEMENS公司20排40层螺旋CT作薄层扫描，层厚5 mm、层距5 mm行横断位图像重建，把传输到VIA221288图像后处理工作站的薄层影像数据再行多平面重组(MPR)、曲面重组(CPR)图像重建。所有病例都结合输尿管的横断位、MPR和CPR三者图像诊断输尿管结石。, http://www.100md.com(黄东亮 思建民)
