Fluoroscopic guided procedures are a mainstay for interventional radiology (IR) procedures. Practice is needed for the novice to interpret fluoroscopic images and simultaneously perform the procedure hands-on as well as control the foot pedal to screen. We describe the development of a training simulation model which simulates the human kidney, ureter, and bladder.
Stereolithography (SLA) 3D print technology using SLA resin and Anycubic SLA printer were employed. A plastic tubing was used to connect the 3D printed kidney and bladder as the ureter. This simulation model permits fluoroscopic guided filling of "pelvicalyceal system" with contrast as well as ureteric stenting, guidewire, and drainage catheter manipulation. Effectiveness of the model to attain skills for nephrostomy exchange and ureteric stenting was obtained via questionnaire from trainees prior to and after utilizing the model.
The 3D printing simulation model of the kidney, ureter, and bladder system enables trainees to perform nephrostomy exchange, nephrostogram, and antegrade stenting. Participants felt more confident to perform the procedures as they were more familiar with the procedure. Besides that, participants felt their wire and catheter manipulation skills have improved after using the simulation model.
Neph-ex simulation model is safe and effective for hands-on training in improving proficiency of fluoroscopy-guided nephrostomy exchange and antegrade ureteric stenting.
As of our knowledge, there are no commercially available simulation models for fluoroscopic guided nephrostomy exchange and ureteric stent deployment. No article on nephrostomy exchange simulation model has been published before.
透视引导下的介入放射学（IR）程序是该领域的主要方法。新手需要进行实践，以解读透视图像，同时进行实际操作并控制脚踏板以进行筛选。我们描述了一种培训模拟模型的开发，该模型模拟了人体的肾脏、输尿管和膀胱。
使用立体光刻（SLA）3D 打印技术和 SLA 树脂以及 Anycubic SLA 打印机。使用塑料管将 3D 打印的肾脏和膀胱连接起来，作为输尿管。该模拟模型允许透视引导下向“肾盂系统”中注入对比剂以及进行输尿管支架置入、导丝和引流导管操作。通过学员在使用模型前后填写问卷，了解该模型在获得经皮肾造口术交换和输尿管支架置入技能方面的有效性。
肾脏、输尿管和膀胱系统的 3D 打印模拟模型使学员能够进行经皮肾造口术交换、肾盂造影和逆行支架置入。学员们表示，由于对手术更加熟悉，他们更有信心进行这些手术。此外，学员们还表示，在使用模拟模型后，他们的导丝和导管操作技能得到了提高。
Neph-ex 模拟模型在提高透视引导下经皮肾造口术交换和逆行输尿管支架置入的熟练度方面是安全且有效的。
据我们所知，目前没有市售的用于透视引导下经皮肾造口术交换和输尿管支架置入的模拟模型。之前也没有关于经皮肾造口术交换模拟模型的文章发表。
