彩色多普勒闪烁伪像诊断膀胱结石临床价值的研究

The diagnostic value of the twinkling artifact in bladder stone

目的探讨彩色多普勒闪烁伪像诊断膀胱结石的临床价值。方法选取经CT检查证实的膀胱单发结石患者132例,运用二维超声测量结石大小并进行分组,观察并记录各组结石后方声影显示情况,应用彩色多普勒超声观察并记录各组结石后方闪烁伪像显示情况,对显示率进行统计分析。结果 132例膀胱结石声影显示率为72.7%,闪烁伪像显示率为84.8%,差异有统计学意义。A组(d≤10mm)膀胱结石共40例,声影显示率为42.5%、闪烁伪像显示率为80.0%,差异有统计学意义;B组(11mm≤d≤20mm)膀胱结石共65例,声影显示率为86.2%、闪烁伪像显示率为86.2%,差异无统计学意义;C组(d≥21mm)膀胱结石共27例,声影显示率为85.2%、闪烁伪像显示率为88.9%,差异无统计学意义。结论彩色多普勒闪烁伪像诊断膀胱结石具有重要意义,尤其对于诊断较小膀胱结石更具临床价值。

Objective To evaluate the diagnostic value of the twinkling artifact in bladder stone.Methods A total of 132 patients with single bladder stones were enrolled in the study from February 2015 to December 2016.All bladder stones were confirmed by non-contrast helical computerized tomography.The bladder stones were classified into grades according to stone size.The acoustic shadowing （AS） and twinkling artifact （TA） level of bladder stones were confirmed with gray-scale imaging and CDFI.The incidence of AS and TA was comparatively analyzed.Results There was significant difference in the incidence between the AS（72.7%） and TA（84.8%） of 132 bladder stones（P〈0.05）.A significant difference in the incidence was observed between the AS（42.5%） and TA（80.0%） of the bladder stones in grade A（d≤10 mm）（P〈0.05）.There was no statistically significant difference in the incidence between the AS（86.2%） and TA（86.2%） of the bladder stones in grade B（11 mm≤d≤20 mm）, and between the AS（85.2%） and TA（88.9%） of the bladder stones in grade C（d≥21 mm）（P〉0.05）.Conclusion The twinkling artifact is useful in the diagnosis of bladder stone, especially in small stone.
