Design and assessment of a penile fracture simulation model.

OBJECTIVE

To design and assess a novel penile fracture simulation model for teaching penile fracture repair.

METHODS

We used a validated circumcision simulator to create a model. Foreskin for a circumcision was divided into two halves. A transverse slit ("simulated fracture") was created on one part of the first half of the foreskin (mimicking "tunica") and was applied over the penile model. A red jelly tablet ("clot") was placed underneath the cut. A second full-length of foreskin was applied over it to cover the defect. The model was assessed by participants and expert faculty at the Urology Simulation Boot Camp. Evaluation was performed using a 5-point Likert Scale questionnaire. Data was analysed using Microsoft Excel and IBM SPSS Statistics V25. The intra-class correlation was calculated using a "One-way random model".

RESULTS

Twenty-two urology trainees and four experts participated in the evaluation. The majority of trainees strongly agreed (59%, n = 13) the model is useful for training with experts similarly agreeing in 75% of cases. The appearance of penile fracture was considered good by both trainees (68%, n = 14) and faculty (75%). Overall, the ability of the model to represent a realistic simulation of the task was considered excellent by 23% of participants and good by 64%. Personal confidence after simulation in managing a similar situation was considered high among trainees. The main difficulties reported were related to fascial planes and urethra.

CONCLUSION

This is the first simulation model for penile fracture repair and has demonstrated face validity at a national urology bootcamp.
