目的　探讨使用3ds Max软件的空间建模技术实现对大鼠原位与异位肾移植仿真模拟的简单方法。  方法　根据大鼠实体解剖，使用Autodesk 3ds Max 8 SP2软件运用放样、布尔运算、多边形造模、倒角剖面和车削等手段，对肾、肾上腺、血管、膀胱、气管、甲状腺和血管等器官进行真实比例构建，合并到腹部及颈部移植场景中，并安装自由摄像头经渲染后获取各角度的三维图像。  结果　成功构建出肾移植相关器官以及大鼠原位，右髂窝位及颈前部的肾移植场景，可作为动物实验的可靠参考，提高手术成功率。  结论　3ds Max的三维非几何体形状器官的造模及场景构建方法，具有可重复性强，方法简单，在个人电脑上易实现的特点。

Objective　To investigate the simple spacial 3ds Max model reconstructing  orthotopic and heterotopic kidney transplantation in rat.　Methods　Based on the anatomic structures of rat, the following organs, such as kidney, adrenal gland，blood vessel, bladder, airtubs and glandula thyreoidea were reconstructed using the commands of loft, boolean controler, poly select, bevel profile, lethe et al. Those virtual organs were then merged into the abdomen and neck scenes, at the same time, installed free camera was used to get 3D images after rendering.　Results　 Organs related with kidney transplanation were reconstructed and simulated the scenes in situ，right iliac fossa as well as anterior site of neck successfully, which can provide reliable references for improving surgery effects of animal operation.　Conclusions　The 3D model building methods of non geometric shape organs and scenes of 3ds Max have the advantages of repeatibility and easy to perform in personal computer.
