B超与多层螺旋CT在输尿管结石所致急性肾绞痛中的诊断价值对比

目的对比分析多层螺旋CT（MSCT）与B超在诊断输尿管结石所致急性肾绞痛中的应用价值。方法回顾性选取我院2018年5月~2019年12月收治住院治疗的输尿管结石患者60例的B超及MSCT影像资料，分析B超及MSCT对不同部位的输尿管结石的诊断率，B超对输尿管结石的诊断敏感性与结石大小关系，并一步分析B超对输尿管结石引起其它MSCT征象诊断的敏感性。结果MSCT对输尿管上、中、下段结石的检出率均高于B超，差异有统计学意义（98.3% vs 70%，P < 0.05）；B超对结石直径≥6 mm与 < 6 mm的敏感性差异有统计学意义（χ2=3.951，P < 0.05），且MSCT对输尿管结石引起的肾积水，输尿管扭曲，肾周渗出征像检出率明显高于B超（P < 0.05）。结论MSCT对门诊或急诊可疑输尿管结石所致的急性肾绞痛患者具有更可靠的诊断价值，推荐作为首选检查方法。 

Comparation of the diagnostic value of B-ultrasound and MSCT in acute renal colic caused by ureterolith

ObjectiveTo analyze the value of MSCT and B ultrasound in the diagnosis of acute renal colic caused by ureteral calculi.MethodsSixty cases of ureteral calculi treated in our hospital from May 2018 to December 2019 were retrospectively selected for B-ultrasound and MSCT imaging data. The diagnostic rate of B-ultrasound and MSCT for different ureteral calculi was analyzed, the relationship between the diagnostic sensitivity of B-ultrasound to ureteral calculi and the size of calculi was analyzed, and the sensitivity of B-ultrasound to the diagnosis of other MSCT signs caused by ureteral calculi was analyzed in further step.ResultsThe detection rate of MSCT in upper, middle and lower ureteral calculi was higher than that of Bultrasound(98.3% vs 70%, P < 0.05). The difference between the sensitivity of B-ultrasound to calculi with diameter ≥6 mm and < 6 mm was significant (χ2=3.951, P < 0.05). The effect of MSCT on hydronephrosis caused by ureteral calculi and the detection rate of ureter distortion and perirenal exudation was significantly higher than that of ultrasonography (P < 0.05).ConclusionMSCT is more reliable in the diagnosis of acute renal colic caused by ureteral calculi in outpatient or emergency department.
