Validation of the Advanced Scope Trainer for Flexible Ureterorenoscopy Training

Abstract

ObjectiveTo validate the Advanced Scope Trainer (AST; Mediskills, Northampton, UK). The AST is a currently unvalidated simulator, developed for flexible ureterorenoscopy (fURS) training.This study aims to assess the face, content, construct and concurrent validity to assess the level of transferability of skills to the OR. Materials and MethodsThis prospective, observational and comparative study recruited novices (n=19) and trainees (n=34) with participants performing a diagnostic fURS, followed by removal of a lower pole stone, on the AST. 15 participants performed a fURS on fresh frozen cadavers to assess concurrent validity. Trainees were supervised by expert urologists (n=7) during each procedure. Performance was evaluated using the validated OSATS assessment. Face and content validity were demonstrated by anonymous surveys from participants and faculty.

One‐surgeon basketing technique for stone extraction during flexible ureteroscopy for urolithiasis: A comparison between novice and expert surgeons

“…developed the artificial pyelocaliceal models made of styrene foam in a polypropylene box (T‐Box; 150 × 103 × 47 mm) for f‐URS training 21 . Furthermore, visual feedback training using an advanced scope trainer (Mediskills, Northampton, UK) might provide an opportunity to improve device operation, handling and coordination 22 . Three‐dimensional reconstruction of a physical renal model might be useful for URS training 23 .…”

A High-Fidelity Artificial Urological System for the Quantitative Assessment of Endoscopic Skills

“…For instance, Villa et al developed a low-cost and portable box model (K-box) for the training of fURS and endourology [17]. AI-Jabir et al presented an Advanced Scope Trainer (AST, Mediskills Limited, Northampton, UK), which allows the training of both basic and advanced procedures [18]. However, there still remain challenges in developing a realistic artificial organ phantom system with detailed anatomy, providing realistic imaging results as well as enabling quantitative feedback on the surgical performance to the trainees [19,20].…”
