三种检查方式对输尿管结石所致急性肾绞痛诊断价值的比较

Comparison of Ultrasound, KUB Radiography and Nonenhanced Multi-slice Computer Tomography for Diagnosis of Acute Renal Colic Caused by Ureteric Calculi

目的比较超声、泌尿系平片(KUB)和螺旋CT平扫对输尿管结石所致急性肾绞痛诊断的价值,为临床诊断提供一种高效、无创的检查方法.方法选取2011年1月至2013年8月在昆明医科大学第二附属医院泌尿外科确诊为输尿管结石的患者194例,其中9例为双侧输尿管结石,共203侧.所有患者均行超声、KUB和螺旋CT平扫检查,将3种检查结果与金标准进行对比研究.结果于多层螺旋CT平扫诊断符合率100%,KUB诊断符合率为79.31%,超声检查诊断符合率为73.40%.螺旋CT平扫诊断符合率明显高于KUB及超声,统计学分析,差异有统计学意义(P<0.01).KUB及超声对输尿管结石的诊断符合率统计学分析差异无统计学意义(P>0.05).结论非增强螺旋CT平扫对输尿管结石所致急性肾绞痛的诊断价值优于超声和KUB,是一种高效、准确的检查方法.

Objective To provide a highly efficient and noninvasive examination method for clinical diagnosis,we compared the diagnostic value among ultrasound, KUB and nonenhanced multi- slice CT for patients with acute renal colic caused by ureteric calculi. Methods 194 patients who were diagnosed ureteric calculi in the department of urology between January 2011 and August 2013. All patients were examined by nonenhanced ultrasound, KUB and multi- slice CT, and the findings were compared with the gold standard. Results The diagnostic coincidence rate of nonenhanced multi- slice computer tomography,KUB and ultrasonography was 100%,79.3%,and 73.4%,respectively. The diagnostic accuracy of ureteral stone by CT（100%） was significantly higher than that by ultrasound（P〈0.01）. There was no difference between ultrasound and KUB in diagnosis coincidence rate of ureteral calculi（P〉0.05）. Conclusion Nonenhanced multi- slice CT is a highly efficient and accurate method for the diagnosis of acute renal colic caused by ureteral calculi, and it is superior to ultrasound and KUB.
