B超诊断输尿管结石价值【摘要】 目的 评价B超在输尿管结石中的诊断价值。方法 对100例经手术取石、体外震波碎石和综合疗法排石证实为输尿管结石患者进行B超检查诊断分析。结果 本组100例输尿管结石患者中,B超诊断正确率为94.00%,无假阳性,漏诊6例,占6.00%。结论 B超诊断输尿管结石假阳性率低,可清晰显示X线阴性结石,有较高的临床应用价值和为临床及时准确地提供诊断和治疗依据,是急性肾绞痛的首选检查方法,特别是在基层医疗单位为首选检查方法。? 【关键词】 输尿管结石;B型超声;漏诊? ? Diagnostic value of B type ultrasound in ureteral calculi LI Cheng. Department of Ultrasound, Peoples Hospital of Deyang City, Sichuan, 618100 China 【Abstract】 Objective To evaluate the diagnostic value of B type ultrasound in ureteral calculi. Methods B type ultrasound examination were performed on 100 cases with ureteral calculi who were confirmed by open surgery,extracorporeal shock wave lithotripsy and comprehensive therapy. Results The diagnostic accuracy was 94.00% in 100 cases,no false positive was found,and the rate of missed diagnosis was 6.00%(6 cases). Conclusion B type ultrasound has a high application value in the diagnosis of ureteral calculi,which has low false positive rate and can clear display negative stone. It can also afford some accurate clues for diagnosis and clinical treatment in time according to abdomenal B type ultrasound and it will be preferred in way for diagnosis of acute nephrite colic especially in basic hospitals.? 【Key words】 Ureteral calculi; B type ultrasound;Missed diagnosis ?
