摘　　要：目的 探讨急诊B超对肾绞痛病因的诊断效率。方法 回顾性研究2014年8月-2015年9月行急诊B超检查的392例肾绞痛患者,其中228例行CT检查,采用χ-2检验与Fisher确切概率法评价B超敏感性与结石大小、位置、肾积水的关系,运用Pearson双变量相关分析研究B超结石大小与CT的相关性。结果 急诊B超诊断输尿管结石敏感性为90.5%,对上、中、下段结石敏感性分别为98.5%、83.8%、81.9%（P〈0.05）,对〈6 mm,6-10 mm,10-20 mm,〉20 mm结石敏感性依次为73.9%、93.9%、95.7%、100.0%（P〈0.05）,B超在有肾积水与无肾积水条件下检测结石敏感性分别为92.0%、72.0%,B超检测结石大小与CT高度相关,其Pearson相关系数为0.781（P〈0.05）。结论 急诊B超诊断肾绞痛患者的病因非常有效,其敏感性随结石增大而增加,上段结石高于中、下段,有肾积水高于无肾积水,特别对于〉6mm的结石,B超与CT结石大小有较高符合率。Objective To explore the diagnosis effect of emergency B ultrasound on the pathogenesis of renal colic. Methods A total of 392 patients with renal colic who received emergency B ultrasound examination from August 2014 to September 2015 were retrospectively investigated. Among them, 228 patients were given CT examination, and χ^2 test and Fisher＇s exact test were applied to evaluate the correlation between the sensitivity of B ultrasound and calculus size, position and hydronephrosis. Pearson＇s bivariate correlation analysis was applied to study the correlation between B ultrasound and CT in the diagnosis of calculus size. Results The sensitivity of emergency B ultrasound in the diagnosis of ureteral calculus was 90.5%. The sensitivity in the diagnosis of upper, middle calculus and lower calculus was 98.5%, 83.8% and 81.9% respectively （P〈0.05）. The sensitivity in the diagnosis of the calculus smaller than 6 mm, 6- 10 mm, 10-20 mm and larger than 20 mm was 73.9%, 93.9%, 95.7% and 100.0% respectively（P〈0.05）. The sensitivity of B ultrasound with hydronephrosis and without hydronephrosis in the diagnosis of calculus was 92.0% and 72.0%. B ultrasound was largely correlated to CT in the diagnosis of calculus size, and Pearson correlation coefficient was 0.781 （P〈0.05）. Conclusion Emergency B ultrasound in the diagnosis of the pathogenesis of renal colic is highly effective, and its sensitivity increases along with the increasing calculus size. The sensitivity is higher in upper calculus than in lower, middle calculus, and the sensitivity is higher with hydronephrosis than without hydronephrosis. Especially for the calculus larger than 6 mm, B ultrasound and CT in the diagnosis of calculus size have higher accordance rate.
