The aims of this study were to test a novel simulation platform suitable for flexible cystoscopy using a standard scope, to assess the platform's proposed use as a training tool for flexible cystoscopy, and to assess the user experience through surveyed response.
Thirty-one urologists (11 novices, 20 experts) were evaluated using a novel light-based bladder model and standard flexible cystoscope. Time to complete full inspection of the simulated bladder was measured, and the scope trajectory was recorded. Participants also completed a survey of the training platform.
Thirty participants completed a simulated inspection of a portable bladder model with a mean ± SD time for 153.1 ± 76.1 seconds. One participant failed to complete. Novice urologists (defined as those having completed less than 50 flexible cystoscopies in clinic) had a mean ± SD time of 176.9 ± 95.8 seconds, whereas with experts, this decreased to 139.3 ± 60.7 seconds. Dynamic trajectory maps identified "blind spots" within each user's cystoscopy performance. In a poststudy follow-up, 27 participants considered the tool valuable or extremely valuable for training, whereas 19 participants considered that the tool either very well or excellently replicated the clinical setting. All participants ranked the tool as very good or excellent for overall quality of training.
Advances in electronic technology make portable low-cost models a potential low-cost alternative to endourology training platforms. In providing a quantifiable measure of user performance, the tool may shorten the learning curve in flexible cystoscopy and, potentially, reduce clinical errors and provide quantifiable measures for further clinical training.
本研究旨在测试一种适用于标准镜的新型软性膀胱镜模拟平台,评估该平台作为软性膀胱镜培训工具的应用,并通过调查反馈评估用户体验。
31 名泌尿科医师(11 名新手,20 名专家)使用新型基于光的膀胱模型和标准软性膀胱镜进行评估。测量完成模拟膀胱全面检查的时间,并记录镜体轨迹。参与者还完成了培训平台的调查。
30 名参与者完成了便携式膀胱模型的模拟检查,平均(±SD)时间为 153.1 ± 76.1 秒。1 名参与者未能完成。新手泌尿科医师(定义为在临床中完成的软性膀胱镜检查少于 50 次)的平均(±SD)时间为 176.9 ± 95.8 秒,而专家的时间缩短至 139.3 ± 60.7 秒。动态轨迹图确定了每位用户膀胱镜检查性能中的“盲点”。在后续研究随访中,27 名参与者认为该工具对培训很有价值或极具价值,而 19 名参与者认为该工具非常或极好地复制了临床环境。所有参与者都将该工具的整体培训质量评为非常好或极好。
电子技术的进步使得便携式低成本模型成为泌尿科培训平台的潜在低成本替代方案。该工具通过提供用户性能的量化衡量,可能缩短软性膀胱镜的学习曲线,并降低临床错误率,提供进一步临床培训的量化指标。
