CT平扫、经腹壁超声对输尿管结石所致急性肾绞痛的诊断效能对比

Diagnostic efficacy of CT plain and transabdominal ultrasound for acute renal colic caused by ureteral calculi

目的旨在探讨CT平扫、经腹壁超声对输尿管结石所致急性肾绞痛的诊断效能。方法选取我院2018年1月至2019年1月收治的输尿管结石所致急性肾绞痛患者共150例,所有患者均进行了经腹壁超声及CT平扫检查,收集150例患者的临床资料及影像学资料,比较两种检查对输尿管结石所致急性肾绞痛的诊断效能。结果经腹壁超声检查对肾绞痛尿道结石患者的诊断符合率、误诊率分别为98.66%、1.33%,CT平扫检查对肾绞痛尿道结石患者的诊断符合率、误诊率分别为100.00%、0.00%,CT平扫检查对肾绞痛尿道结石患者的诊断符合率优于经腹壁超声检查,差异具有统计学意义(P<0.05);CT平扫对输尿管段结石总检出率为99.37%(160/161),经腹壁超声对输尿管段结石总检出率为90.06%(145/161),CT平扫对输尿管段结石总检出率明显高于经腹壁超声(P<0.05)。结论CT平扫、经腹壁超声检查均能有效显示输尿管结石影像特征,其中CT平扫对输尿管结石诊断灵敏性、特异性和准确性优于经腹壁超声。

Objective To investigate the diagnostic efficacy of CT plain and transabdominal ultrasound for acute renal colic caused by ureteral calculi.Method A total of 150 patients with acute renal colic caused by ureteral calculi admitted to our hospital from January 2018 to January 2019 were enrolled.All 150 patients underwent transabdominal ultrasonography and CT scan.The clinical data and images of 150 patients were collected.The diagnostic efficacy of both tests for acute renal colic caused by caused by ureteral calculi was compared.Results The diagnostic accuracy and misdiagnosis rate of transabdominal ultrasonography for renal colic caused by ureteral calculi were 98.66%and 1.33%,respectively.The diagnostic accuracy and misdiagnosis rate of CT scan for renal colic caused by ureteral calculi were 100.00%and 0.00%,respectively.The diagnostic accuracy of CT scan for renal colic caused by ureteral calculi was better than that of transabdominal ultrasonography(P<0.05).The total detection rate of ureteral calculi was 99.37%(160/161)by CT plain scan.The total detection rate of ureteral calculi was 90.06%(145/161)by transabdominal ultrasound.The total detection rate of ureteral calculi by CT plain scan was significantly higher than that of transabdominal ultrasonography(P<0.05).Conclusion CT plain scan and transabdominal ultrasonography can effectively display the image characteristics of ureteral calculi.The sensitivity,specificity and accuracy of CT plain scan for ureteral calculi are better than those of transabdominal ultrasonography.
