三维腔内彩色多普勒超声与经腹超声、DR IVP诊断输尿管下段阴性结石的对比研究

比较三维腔内彩色多普勒超声与经腹超声、DR静脉尿路造影(IVP)在诊断输尿管下段阴性结石的临床价值。方法回顾性分析2009年2月至2011年8月139例经临床证实的输尿管下段阴性结石患者的临床资料,全部病例均行三维腔内彩色多普勒超声检查,并与经腹超声、DR IVP结果对照。结果三维腔内彩色多普勒超声检查诊断输尿管下段阴性结石的检出率为94.24%,明显高于经腹部超声(77.70%)及DR IVP(49.64%)(P<0.05)。三维腔内彩色多普勒超声可以更好地显示肾脏积液的情况,肾实质的厚度、回声及观察输尿管梗阻和肾功能的情况。结论三维腔内彩色多普勒超声检查诊断输尿管下段阴性结石优于经腹超声、DR IVP检查。

Comparison of Three-dimensional Endosonography,Transabdominal Ultrasound and DR IVP for Diagnosis of Lower Non-opaque Ureterolith

Objective To compare the diagnostic values of three-dimensional endosonography,transabdominal ultrasound and DR intravenous pyelography(IVP) in lower non-opaque ureterolith.Methods Data of 139 cases of clinically proven lower non-opaque ureterolith from February 2009 to August 2011 were retrospectively analyzed.Three-dimensional endosonography diagnosis was compared with transabdominal ultrasound and DR IVP.Results The detection rate of ureterolith by three-dimensional endosonography(94.24%) was significantly higher than that by transabdominal ultrasound(77.70%) and DR IVP(49.64%)(P<0.05).Furthermore,three-dimensional endosonography provided more direct information about renal effusion,renal parenchymal thickness,ureteral obstruction and renal function.Conclusion Three-dimensional color Doppler ultrasound is superior to transabdominal ultrasound and DR IVP for the diagnosis of lower non-opaque ureterolith.
