多层螺旋CT诊断输尿管结石的价值观察

Value of Multi-slice Spiral CT in the Diagnosis of Ureteral Calculi

目的探讨多层螺旋CT(MSCT)对于输尿管结石的临床诊断价值。方法收集2016年3月至2019年3月我院收治的输尿管结石患者154例,分析其CT表现,并与临床结果进行对比。结果 154例输尿管结石,MSCT诊断146例,诊断准确率为94.81%。146例MSCT正确诊断的输尿管结石中,结石部位在输尿管腹腔段41例,盆腔段61例,膀胱壁内段38例;双侧输尿管6例。结石CT轴位呈圆形、类圆形或不规则高密度影,CT值为160~1170HU;多平面重建(MPR)上结石呈类圆形、柱子状或呈不规则形状。其中结石上端输尿管或肾盂、肾盏伴程度不一的扩张积水74例(50.68%),输尿管结石有软组织边缘征表现者89例(60.96%)。结论 MSCT对输尿管结石有重要诊断价值,可作为临床诊断首选。

Objective To explore the clinical diagnostic value of multi-slice spiral CT(MSCT) in the diagnosis of ureteral calculi.Methods A total of 154 patients with ureteral calculi admitted to our hospital from March 2016 to March 2019 were collected.The CT findings were analyzed and compared with clinical results.Results Among 154 patients of ureteral calculi,146 cases were diagnosed by MSCT with diagnostic accuracy rate of 94.81%.Among the 146 patients of ureteral calculi correctly diagnosed by MSCT,there were 41 cases in the ureteral abdominal segment,61 cases in the pelvic segment,38 cases in the bladder wall inner segment and 6 cases in the bilateral ureters.The CT axis of stones showed circular,pillar or irregular high-density shadows,and the CT value was 160-1170 HU.The stones on multi-planar reconstruction(MPR) showed round,round-like,or irregular shapes.Among them,there were 74 cases(50.68%) of the upper ureter or renal pelvis and renal calyx with different degrees of expansion and 89 cases(60.96%) of soft tissue ma rginal signs of ureteral calculi.Conclusion MSCT has a significant diagnostic value on ureteral calculi and can be used as the primary option in clinical practice.
