To construct three-dimensional (3D) models of renal stones and perform percutaneous nephrolithotomy (PCNL) virtual surgery simulation. Methods CT images were obtained from 8 patients with renal stones. Images segmentation and reconstruction were performed using MIMICS 10.0 software to construct the 3D model of the renal stones, which provided the anatomical relationships between the kidney and the adjacent organs. The optimal PCNL virtual surgery simulation for each individual case was performed using FreeForm Modeling System on the basis of the 3D model.
Eight 3D models of renal stone were constructed. The 3D model of the renal stones represented the interrelationships of the stones, intrarenal vessel, and the collecting system with the adjacent anatomical structures. Individualized PCNL virtual surgery simulations including percutaneous puncture, dilatation and pneumatic lithotripsy were performed successfully in all the 8 3D models.
Digital 3D model of renal stone provides the reliable and comprehensive imaging information for surgical design, and PCNL virtual surgery simulation has important clinical significance to improve the stone clearance rate and reduce the surgical complications.
构建肾结石三维（3D）模型并进行经皮肾镜取石术（PCNL）虚拟手术模拟。方法 收集8例肾结石患者的CT图像，采用MIMICS 10.0软件进行图像分割与重建，构建肾结石3D模型，呈现肾脏与相邻器官之间的解剖关系。基于3D模型，使用FreeForm Modeling System对每个病例进行最佳PCNL虚拟手术模拟。
构建了8个肾结石3D模型。肾结石3D模型展示了结石、肾内血管、集合系统与相邻解剖结构之间的相互关系。在所有8个3D模型中均成功进行了包括经皮穿刺、扩张和气压弹道碎石术在内的个体化PCNL虚拟手术模拟。
肾结石数字3D模型为手术设计提供了可靠且全面的影像信息，PCNL虚拟手术模拟对提高结石清除率和减少手术并发症具有重要临床意义。
