摘　　要：目的基于CT扫描原始图像构建小儿肾结石三维模型,为手术方式的选择提供参考。方法选取9例肾结石患儿分别进行泌尿系CT扫描检查,所得资料以DICOM格式储存并将其导入医学影像软件Mimics,通过自动与人工描绘等功能提取所需区域进行三维重建,获得小儿肾结石三维模型,并利用机械画图软件Solidworks建立手术器械模型,对三维肾结石模型进行虚拟仿真手术操作。结果成功建立了包含骨骼、肾实质、集合系统、血管、结石及毗邻器官在内的小儿肾结石三维模型及手术器械模型,并完成虚拟手术操作。结论通过Mimics软件结合CT扫描资料建立小儿肾结石三维模型有效、可行,能直观地显示肾内结构及毗邻脏器,有助于术者进行术前规划。Objective To provide rationales for selecting surgical procedures through establishing a three-dimensional model of renal stone on computed tomography （ CT） in children. Methods Spiral CT in urinary system was performed in 9 children with renal stones. The acquired data stored in DICOM format were imported into medical imaging software Mimics. 3D reconstruction was performed through automatic and manual mapping of required areas to obtain the three-dimensional models of renal stones in children. The surgical in-strument model was established by mechanical drawing software Solidworks based upon virtual simulation. Oper-ation was performed on three-dimensional model of renal stones. Results The three-dimensional model of re-nal stone in children,including bones,renal substance,collective system,blood vessels,stones and adjacent or-gans, was established. And surgical instrument model and virtual operation were completed successfully. Con-clusion The three-dimensional modeling of pediatric renal stone combining Mimics software and spiral CT data is both feasible and effective. It can delineate the internal structure of kidney and adjacent viscera. Individual-ized surgical procedures may be developed with virtual surgical techniques for better preoperative planning.
