Abstract

Objective: To investigate the value of the physical Simbla Transurethral Resection of a Bladder Tumor (TURBT) simulator as an educational tool within urological residency training, by means of a training needs analysis (TNA) and assessment of its feasibility, acceptability, and face, content, and construct validity. Methods: To analyze the training needs for TURBT, procedural steps and pitfalls were identified and the TNA was completed during an expert consensus meeting. Participants (n=76) were divided into three groups based on their experience in TURBT: novices, intermediates, and experts. Participants performed two standardized TURBT procedures on the simulator. Face validity and content validity, as well as feasibility and acceptability, were assessed with a quantitative survey. Construct validity was assessed by comparing the performance of novices, intermediates, and experts on resection time, quality of tumor resection, and overall performance. Results: Of the 21 procedural steps and 17 pitfalls defined in TNA, 13 steps and 8 pitfalls were covered by the Simbla. Participants rated the Simbla's overall realism (face validity) with a score of 8 of 10 (range 6-9). The simulator was judged to be most useful (content validity) for learning eye-hand coordination: score 8 (6-10). All aspects regarding realism and usefulness were rated above the acceptability threshold of 6/10. Intermediates (100%) and experts (96%) considered the Simbla to be a useful educational tool within the urological curriculum. Resection time was longer for novices than for experts (p
