目的探讨研究输尿管狭窄的影像学检查的方法和价值。方法对2009年1月——2012年10月我院收治的输尿管狭窄患者89例为临床研究对象,所有患者均经过临床和影像学检查确诊。影像学检查方法包括超声和尿路造影。对比观察超声、逆行尿路造影与临床综合诊断的差异,分析不同部位输尿管狭窄的影像学检查价值。结果超声诊断的符合51例,尿路造影符合77例,其中尿路造影诊断价值更高,P<0.05。其中超声对肾盂输尿管移行区的诊断价值较高,逆行尿路造影对肾盂输尿管移行区-输尿管末端的诊断价值较高。结论在输尿管狭窄的临床诊断中使用尿路造影的诊断准确率较高,但是仍有一定误差,需要给予综合诊断。
Objective To explore the method and value of imaging examination of ureteral stricture. Methods 89 patients with ureteral stricture admitted to our hospital from January 2009 to October 2012 were selected as clinical subjects and all patients were diagnosed clinically and radiologically. Imaging methods include ultrasound and urography. Contrasting the difference of ultrasonic diagnosis, retrograde urography and clinical diagnosis, analyzing the imaging examination value of ureteral stricture in different parts. Results 51 cases were diagnosed by ultrasound and 77 cases by urography. The diagnostic value of urography was higher (P <0.05). Among them, the diagnostic value of ultrasonography in ureteropelvic junction is higher, and the diagnostic value of retrograde urography in the ureteropelvic junction-ureteric end is higher. Conclusion The diagnostic accuracy of urography in the clinical diagnosis of ureteral stricture is high, but there are still some errors, and the need for comprehensive diagnosis.
