摘要
目的探讨多普勒超声、CT检查在尿路结石诊断中的临床应用价值。方法选取我院2018年1月至2018年9月收治的尿路结石患者91例,91例患者均进行了多普勒超声检查及CT平扫,对比两种检查方法对尿路结石患者整体诊断准确率、检出率及漏诊率。结果多普勒超声检查诊断尿路结石的准确率、检出率及漏诊率分别为94.05%、88.11%、11.88%,CT检查对尿路结石的准确率、检出率明显高于多普勒超声检查,漏诊率低于多普勒超声检查,数据差异有统计学意义(P<0.05),多普勒超声检查对肾结石、膀胱结石的检出率分别为85.36%、82.60%,低于CT检查100.00%,数据差异有统计学意义(P<0.05);CT平扫结石CT值64~1093HU,最大直径34mm,结石外观多呈现为类圆形、卵圆形;结石间接征象包括输尿管肾盂积水扩张、肾脏或肾周改变、组织环征。37例患者肾内动脉RI检测结果显示>0.7,或者患者双侧肾内动脉RI差值>0.01。二维灰阶图像结石多表现为高回声,后方伴声影,输尿管结石多见一侧输尿管末端出现喷尿次数减少,彩色尿流减弱。结论多普勒超声、CT平扫均能有效显示不同部位尿路结石,CT平扫对尿路结石准确率、检出率优于多普勒超声检查。
Objective To explore the clinical application value of Doppler ultrasound and CT in the diagnosis of urinary calculi.Methods 91 patients with urinary calculi admitted to our hospital from January 2018 to September 2018 were enrolled.91 patients underwent Doppler ultrasonography and CT scan.Results The overall diagnostic accuracy,detection rate,and missed diagnosis rate of the two examinations for patients with urinary calculi were compared.The accuracy,detection rate and missed diagnosis rate of urinary calculi diagnosed by Doppler ultrasonography were 94.05%,88.11%,and 11.88%,respectively.The accuracy and detection rate of urinary calculi by CT examination were significantly higher than that of Doppler ultrasound.The rate of missed diagnosis was lower than that of Doppler ultrasonography.The difference was statistically significant(P<0.05).The detection rates of kidney calculi and vesical calculi by Doppler ultrasonography were 85.36%and 82.60%,respectively,which were lower than those of CT examination(100.00%).The difference was statistically significant(P<0.05).The CT value of calculi was 64~1093 HU,the maximum diameter was 34mm,and the calculi was mostly round and oval.Indirect signs of calculus included ureteral hydronephrosis,renal or perirenal changes,and tissue ring signs.Results of intra-renal artery RI in 37 patients showed>0.7,or the difference value in bilateral intrarenal artery RI was>0.01.Two-dimensional gray-scale image of calculus showed high echo,accompanied by sound shadow in the rear.Ureteral calculi often showed a decrease in the number of urinations at the end of unilateral ureter and a decrease in color urine flow.Conclusion Doppler ultrasound and CT plain scan can effectively display urinary calculi in different parts.The accuracy and detection rate of CT scan for urinary calculi are better than those of Doppler ultrasonography.
