Abstract

OBJECTIVE

To report on the design of a novel 3D-printed retrograde intrarenal surgery (RIRS) benchtop trainer and detail its validation against real-life experiences.

METHODS

Digital Imaging and Communications in Medicine (DICOM) files of 2 patients with normal computed tomography of the kidney and bladder were converted into stereolithography files to create 3D triangular mesh models. These images were further refined using Autodesk Meshmixer. These 3D models were fabricated through additive manufacturing, a process commonly known as 3D printing, and assembled in a polypropylene case. After development, the model was validated by 40 experienced urologists and urology residents in their final year of training. They were asked to rate the components of the simulation using a 9-point questionnaire.

RESULTS

The model’s value in understanding the principles of RIRS and simulating contextual anatomy had mean scores of 9.43 (standard deviation [SD] = 0.74) and 9.21 (SD = 1.03), respectively. Mean scores for specific steps in RIRS were 8.07 (SD 1.47) for cannulating the ureteric orifice, 8.61 (SD 1.24) for inserting the ureteric access sheath, 9.29 (SD 0.97) for performing a renoscopy and evaluating all the calyces, 9.46 (SD 0.87) for laser lithotripsy, and 9.17 (SD 0.94) for manual stone retrieval. Participants scored the model with a mean score of 9.04 (SD 0.87) regarding realism and a mean score of 9.18 (SD 0.89) when evaluating its ability to enhance a trainee’s confidence in RIRS.

CONCLUSION

The model performed well for all components of RIRS. This model allows high fidelity of the simulation and is cost-effective, portable, durable, reusable, and compatible with standard ureteroscopes.

设计和验证新型 3d 打印逆行肾内手术训练器。

目的报告新型三维打印逆行肾内手术（RIRS）台式训练器的设计情况，并详细介绍其与实际经验的验证情况：方法：将两名肾脏和膀胱正常计算机断层扫描患者的数字成像和医学通信（DICOM）文件转换为立体光刻文件，以创建三维三角形网格模型。使用 Autodesk Meshmixer 进一步完善了这些图像。这些三维模型是通过增材制造（即通常所说的三维打印工艺）制作的，并组装在一个聚丙烯外壳中。模型开发完成后，40 位经验丰富的专家对模型进行了验证，并要求他们使用九分问卷对模拟的各个组成部分进行评分：结果：该模型在理解 RIRS 原理和模拟背景解剖学方面的价值平均值分别为 9.43（标准差 [SD] = 0.74）和 9.21（标准差 = 1.03）。RIRS 具体步骤的平均得分分别为：输尿管口插管 8.07 分（标准差 1.47）、插入输尿管通道鞘 8.61 分（标准差 1.24）、进行肾镜检查和评估所有肾盏 9.29 分（标准差 0.97）、激光碎石 9.46 分（标准差 0.87）和人工取石 9.17 分（标准差 0.94）。学员们对模型真实性的平均评分为 9.04 分（标准差为 0.87 分），对模型增强学员 RIRS 信心的能力的平均评分为 9.18 分（标准差为 0.89 分）：该模型在 RIRS 的所有组成部分方面都表现良好。结论：该模型在 RIRS 的所有组成部分上都表现良好。该模型可实现高保真模拟，而且经济实惠、便于携带、经久耐用、可重复使用，并与标准输尿管镜兼容。
