Training in experimental models is a valid option that improves the outcomes and shortens surgical learning curves. Our objective was to develop a 3D printed plastic model for teaching, training and education in flexible ureteroscopy, analyzing costs and suitability for the practice of this surgical technique.
A 3D printed model was developed based on a CT scan from a real-life patient's upper urinary tract. Horos™ software was used for segmentation and an FDM-Ultimaker for 3D printing. Renal calyces were numbered to be identified, as in the European Association of Urology Endoscopic Stone Treatment training curriculum, Task 4. The following were used: Innovex single-use flexible ureteroscope (Palex) and nitinol baskets (Coloplast).
Printing time was 19 h, with a total cost of €8.77. The three-dimensional model allowed the insertion of the flexible ureteroscope and the exploration of the renal calyces by urologists in training as well as in current practice of the specialty without difficulty. The model also allowed the use of baskets and the mobilization and removal of previously placed stones.
We unveil a valid three-dimensional model for flexible ureteroscopy training exercises with reasonable costs, which will allow acquiring the necessary skills and confidence to initiate the procedure in a real-life scenario.
在实验模型中进行培训是一种有效的选择，可以提高手术效果并缩短手术学习曲线。我们的目标是开发一种用于柔性输尿管镜检查的教学、培训和教育的 3D 打印塑料模型，分析其成本和对该手术技术实践的适用性。
根据真实患者上尿路的 CT 扫描，开发了一种 3D 打印模型。使用 Horos™软件进行分割，使用 FDM-Ultimaker 进行 3D 打印。肾脏盏被编号以便识别，这与欧洲泌尿外科内镜结石治疗培训课程中的任务 4 一致。使用 Innovex 一次性使用柔性输尿管镜（Palex）和镍钛诺篮（Coloplast）。
打印时间为 19 小时，总成本为 8.77 欧元。三维模型允许受训泌尿科医生和该专业的当前从业者毫不费力地插入柔性输尿管镜并探查肾脏盏。该模型还允许使用篮子以及移动和取出先前放置的结石。
我们揭示了一种用于柔性输尿管镜检查培训练习的有效三维模型，具有合理的成本，这将使医生能够在真实场景中获得必要的技能和信心来启动该程序。
