Abstract

Abstract Objective Penile fracture is an uncommon urological emergency, limiting opportunities for trainees to gain operative experience. We developed and evaluated a novel low-cost, non-living bovine penile model for simulation training in penile fracture repair, assessing perceived realism, usefulness for training and impact on confidence. Methods The model was evaluated during the 2023 and 2024 Advanced Urology Simulation Boot Camps. A bovine penis was modified to reproduce a corporal fracture and associated urethral injury, enabling trainees to practise surgical exploration and repair. Consultant faculty and delegates completed an anonymised post-course evaluation using five-point Likert scales. Responses were analysed descriptively and compared between faculty and delegates using two-tailed Mann–Whitney U tests with Holm adjustment for multiple comparisons. Results Forty-eight participants completed the evaluation, comprising 4 consultant faculty and 44 delegates. Most delegates (36/44, 81.8%) had performed fewer than five penile fracture repairs, whereas 3/4 faculty had performed more than 20. Ratings were favourable across all measures of simulation realism, with corporal fracture realism receiving the strongest evaluation; 45/48 (93.8%) rated it realistic or very realistic. All participants agreed or strongly agreed that the model was useful for training, while 44/48 (91.7%) agreed or strongly agreed that their confidence in managing penile fracture had increased. No statistically significant differences between faculty and delegates remained following Holm adjustment across the questionnaire items. Conclusions The bovine penile model demonstrated high perceived realism and usefulness for training, with comparable evaluations between faculty and delegates despite differences in previous operative experience. This low-cost biological model provides a practical simulation option for penile fracture repair where opportunities for operative training are limited.
