【摘要】：目的探讨CT尿路造影(CTU)及三维重建对泌尿系结石的诊断价值。方法回顾性分析本院2009～2011年间因临床诊断为泌尿系结石行CT扫描资料。扫描包括常规平扫、肾皮质期、肾实质期、肾排泄期,根据梗阻程度选择合适的扫描延迟时间,所有原始图像均采用三维重建技术进行重建,得出CTU后处理图像。结果本组60例泌尿系结石患者中,单纯肾结石15例,单纯输尿管结石23例,单纯膀胱结石7例,肾结石合并输尿管结石10例,输尿管结石合并膀胱结石3例,肾、输尿管及膀胱多发结石2例。结论多层螺旋CT具有扫描速度快、优良的成像质量和强大的图像后处理功能而获得多种模式的二、三维图像,并可多平面、多方位、立体地显示肾脏、尿路及血管病变,结合泌尿系造影可提高结石检出率及评价尿路有无梗阻及其程度,对IVP不显影或不能确诊的泌尿系结石可明确诊断,可为临床医师手术提供直观资料。
[Abstract]:Objective to evaluate CT urography (CTU) and three-dimensional reconstruction in the diagnosis of urinary calculi.Methods CT scan data of urolithiasis from 2009 to 2011 were analyzed retrospectively.The scanning includes routine plain scan, renal cortex phase, renal parenchyma phase, renal excretion phase. According to the degree of obstruction, the appropriate scanning delay time is selected. All the original images are reconstructed by three-dimensional reconstruction technique, and the post-processing images of CTU are obtained.Results among 60 patients with urinary calculi, there were 15 cases of simple renal calculi, 23 cases of ureteral calculi, 7 cases of simple bladder stones, 10 cases of renal calculi with ureteral calculi, 3 cases of ureteral calculi, 3 cases of ureteral calculi, and 3 cases of ureteral calculi.Multiple calculi in ureter and bladder: 2 cases.Conclusion Multi-slice spiral CT has the advantages of high scanning speed, excellent imaging quality and powerful post-processing function to obtain two and three dimensional images of multiple models, and can display renal, urinary and vascular lesions in multiple planes, directions and stereoscopically.Combined with urography can improve the detection rate of stone and evaluate the obstruction of urinary tract and its degree. The diagnosis of urolithiasis without or without diagnosis of IVP can be clearly diagnosed and can provide visual data for clinicians in operation.
