目的总结常规彩色多普勒超声组合拳法对输尿管非典型结石诊断的实用价值,提高彩色多普勒超声对其诊断水平。方法对2008年10月-2014年12月178例输尿管非典型结石患者采用排除法,凸阵、线阵探头加压追踪检查,彩色多普勒超声闪烁伪像辅诊,必要时结合口服利尿剂饮水膀胱充盈聚焦检查,输尿管口射尿多普勒彩色信号观察法与采用腔内探头经阴道超声检查有机组合应用,以确定结石的存在。结果输尿管非典型结石多比较小,患侧输尿管扩张及肾积水程度较轻;输尿管腹段结石5例,盆段结石29例,膀胱壁段结石144例;二维B型超声共检出132枚(74%,132/178),通过彩色多普勒超声观察结石后方闪烁伪像进一步明确检出170枚(96%,170/178),采用腔内探头经阴道超声检出6枚,2例通过适量饮水后对比观察双侧输尿管膀胱入口处喷尿现象,提示存在结石梗阻。结论彩色多普勒超声联合多种探查方法诊断可提高输尿管非典型结石的显示率。
Objective To summarize the practical value of routine color Doppler ultrasound in the diagnosis of atypical ureteral calculi, and to improve the diagnostic value of color Doppler ultrasound. Methods From October 2008 to December 2014, 178 patients with ureteral atypical calculus were treated with exclusion, convex array, linear array sonography, color Doppler sonography, and if necessary oral diuretics Drinking water, bladder filling focus examination, ureteral urethral Doppler color signal observation method and the use of transvaginal sonography probe combination of organic examination to determine the presence of stones. Results Atypical ureteral stones were relatively small, with ipsilateral ureteral dilatation and mild hydronephrosis; ureteral calculi in 5 cases, pelvic stones in 29 cases, and bladder wall in 144 cases; two-dimensional ultrasound B- A total of 170 (96%, 170/178) were detected by color Doppler ultrasonography and flicker artifact was observed in the back of the calculus. Six of them were detected by intravaginal sonography and 2 Case by comparing the amount of drinking water after bilateral ureter at the entrance to the urinary bladder urinary phenomenon, suggesting the presence of stone obstruction. Conclusion The combination of color Doppler ultrasound and multiple probing methods can improve the display rate of ureter atypical calculus.
