64排螺旋CT三维重建对输尿管结石诊断价值
【摘要】目的探讨多层螺旋CT三维重建在输尿管结石的临床应用价值。方法 43例急性季肋部疼痛疑为输尿管结石的患者,分别行B超及急诊CT检查,CT重建后作三维及多平面重建。结果 CT显示输尿管结石41例,上段结石16例,中段结石4例,下段结石21例;左侧23例,右侧18例;~ cm。B超诊断输尿管结石仅34例,余9例未显示。结论螺旋CT三维重建能明确显示输尿管结石的位置和大小,有助于临床及时准确地制订治疗方案。?

【Abstract】 Objective To explore MDCT 3D reconstruction in the value of the clinical application of ureteral 43 patients with acute season ribs suspected of ureteral calculi pain patients respectively, do B super and emergency CT examination, CT reconstruction for 3D and CT scan of the ureteral calculi 41 cases, among which the upside calculus 16 cases, 4 cases middle calculus and under calculus 21 cases. On the left 23 cases, the right 18 cases, calculus size - cm. B-ultrasonic diagnosis of ureteral calculi only 34 cases, 9 cases had not Spiral CT 3D reconstruction can clearly show the size and location of the ureteral calculi, help to clinical timely and accurately make treatment.?

输尿管结石是临床常见病、多发病,可引起尿路梗阻及感染,进而损害肾功能,因此,早期诊断和治疗极为重要。B超、腹部平片(KUB)、静脉肾盂造影(IVP)是检查输尿管结石的常用手段,且发挥了巨大的作用,至今仍被广泛应用,但其敏感性和准确性偏低,且对于小的结石和阴性结石常无法准确诊断。随着多层螺旋CT特别是64层螺旋CT
