摘要
目的:探讨彩色多普勒超声对泌尿系结石的诊断效果,并分析结石大小测量值的准确性。方法:收集我院2015年2月-2016年2月泌尿外科收治的74例可疑泌尿系结石患者,均接受彩色多普勒超声和非增强螺旋CT(NCHCT)检查并测量结石的最大长径,观察两种检查手段的诊断效果和结石大小测量值的准确性。结果:74例可疑泌尿系结石患者经临床随访最终确诊83.78%(62/74);彩色多普勒和NCHCT诊断准确度、灵敏度、特异度相较差异均无统计学意义(P>0.05);彩色多普勒超声结石测量值整体高于NCHCT,其中对<5 mm的结石测量值为(4.84±0.92)mm显著偏高,差异具有统计学意义(P<0.05),Pearson分析彩色多普勒超声、NCHCT结石测量值的差异幅度与结石大小呈显著负相关关系(P<0.05)。结论:彩色多普勒超声对泌尿系结石的诊断与NCHCT较为接近,但对于结石尤其是<5 mm的结石大小测量值易被高估,准确性有待提高。
Objective： To investigate the diagnostic value of color Doppler ultrasound in the diagnosis of urinary calculi, and to analyze the accuracy of the value of stone size measurement. Methods： In our hospital from February 2015 to February 2016 from the Department of Urology, 74 cases of suspected urinary calculi patients underwent color Doppler ultrasound and spiral CT （NCHCT） maximum length measured and checked for stone size, stone size effect and the diagnostic accuracy of the two examination methods were observed and measured values. Results： 74 cases of suspected urinary calculi patients with clinical follow-up were 83.78% （62/74）; color Doppler and NCHCT diagnostic accuracy, sensitivity and specificity compared with the differences were not statistically significant （P〉0.05）; color Doppler ultrasound measurement values higher than the overall NCHCT stones, the stones to measure the value of 5ram is less than （4.84～0.92） mm significantly higher, the difference was statistically significant （P〈0.05）, Pearson analysis of color Doppler ultrasound, NCHCT stone measuring value of the magnitude of the difference and the stone size was a significant negative correlation （P〈0.05）. Conclusion： Color Doppler ultrasound in the diagnosis of urinary calculi and NCHCT is more close, but for the stones, especially the 5mm of the stone size measurement is easy to be overestimated, the accuracy needs to be further improved.
