A Novel Simulated Training Platform and Study of Performance Among Different Levels of Learners in Flexible...

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.
