摘要
目的探讨16层螺旋CT血管分析技术在输尿管狭窄诊断中的应用价值。方法回顾性分析53例经手术或膀胱镜证实的输尿管狭窄16层螺旋CT尿路成像检查并经16层螺旋CT血管分析技术显示的检查结果,且与手术或膀胱镜结果及静脉尿路造影结果对照分析。结果16层螺旋CT血管分析技术能清晰直观显示狭窄段输尿管的管壁和管腔内的直接CT征象,并可拉直准确测量狭窄段输尿管的长度,诊断符合率为95.24%。诊断静脉尿路造影阳性结石伴输尿管炎性狭窄24例,诊断符合率为91.67%;诊断静脉尿路造影阴性结石伴输尿管炎性狭窄11例,诊断符合率为90.91%;诊断输尿管炎性狭窄10例,诊断符合率为90.00%;诊断输尿管癌性狭窄8例,诊断符合率为75.00%;在诊断输尿管狭窄的病因及测量狭窄段输尿管的长度方面明显优于静脉尿路造影。结论16层螺旋CT血管分析技术是在其尿路成像基础上的一种分析技术,可极大地提高对输尿管狭窄的诊断准确率,对临床治疗有重要的指导意义。
Objective To discuss the value of 16-slice CT angiography analysis technology in diagnosis of ureteral stricture. Methods To analyse retrospectively the results of 16-slice CT urography of 53 cases ureteral stricture confirmed by surgery or cystoscopy. The 16-slice CT angiography analysis showed that the results, and compare with the cystoscopy or surgery or intravenous urography findings. Results The 16- slice CT angiography analysis technology displayed directly and clearly the direct CT signs of the ureter wall and lumen to the narrow segment, and straightened the narrow segment and measured accurately the length of ureter, diagnosis rate 95.24%. Diagnosis of intravenous urography positive ureteral stones with inflammatory narrow 24 cases, diagnosis rate 91.67%. Diagnosis of intravenous urography negative ureteral stones with inflammatory narrow 11 cases, diagnosis rate 90.91%. Diagnosis of inflammatory narrow ureter 10 cases, diagnosis rate 90. 0%. Diagnosis of ureteral cancer narrow 8 cases, diagnosis rate 75.0%. It is superior to ureter intravenous urography in diagnosis of cause of narrow ureter and measuring the length of narrow segment. Conclusions The 16-slice CT angiography analysis technology is on the basis of urography. It can greatly improve the diagnostic accuracy of narrow segment and has important guiding significance on clinic.
