Simulation-based flexible ureteroscopy training using a novel ureteroscopy part-task trainer.

Area of Science:

• Medical Education
• Surgical Simulation
• Urology

Background:

• Simulation-based training (SBT) is crucial for novice surgical trainees to master new skills.
• A novel inanimate training model (Cook URS model) was developed for flexible ureteroscopy (fURS).

Purpose of the Study:

• To design and evaluate a SBT curriculum for fURS.
• To validate the utility and realism of the Cook URS training model.

Main Methods:

• A 2-week SBT fURS course was delivered to junior urology residents.
• Training included didactic lectures, hands-on practice, and expert feedback using the Cook URS model.
• Trainee skills were assessed at baseline and post-course using standardized tasks and validated expert review.

Main Results:

• Fifteen residents participated; 80% found the Cook URS model realistic (4.2/5).
• Endourology experts rated the model highly useful (4.9/5), confirming face and content validity.
• Post-course performance showed significant improvements in task completion time (15.76 vs. 9.37 min) and overall scores (19.20 vs. 25.25).
• Performance gains correlated with clinical fURS experience, indicating construct validity.

Conclusions:

• SBT using the Cook URS model effectively enhances short-term technical skills in junior urology residents.
• The Cook URS model possesses strong face, content, and construct validity for fURS training.
