多层螺旋CT对输尿管结石的临床应用价值

Utility of multi-slice spiral CT for detecting ureteral calculi

目的探讨多层螺旋CT在输尿管结石诊断中的临床应用价值。方法71例临床诊断的输尿管结石患者均经常规多层螺旋CT检查,其中8例行增强扫描。结果多层螺旋CT扫描明确显示输尿管结石68例,诊断符合率95.8%,其中结石位于右侧输尿管者37例,左侧25例,两侧6例;位于输尿管3个解剖狭窄处52例。结论多层螺旋CT可全面、立体、直观地显示输尿管结石大小、形态、位置及输尿管梗阻扩张的程度,对输尿管结石的诊断具有重要的临床价值。

Objective To study the utility of multi-slice spiral C T,for detecting ureteral calculi. Methods Seventy-one patients with clinically proved ureteral calculi underwent conventional multi-slice spiral CT scans,of whom,9 patients underwent additional con- trast enhanced CT scans.Results Multi-slice spiral CT scans definitely showed that,68 of 71 patients had ureteral calculi so that the diag- nostic accuracy was 95.8%.For the distribution of ureteral calculi,right lateral ureteral calculi were found in 37 cases,left lateral ureteral calculi were found in 25 cases,bilateral ureteral calculi were found in 6 cases,while those in 3 narrowing places of ureteral anatomic location were found in 52 cases. Conclusion Multi-slice spiral CT can stereoscopically and directly reveal the size,shape and site of ureteral calculi and therefore it has important utility for detecting ureteral calculi.
