The aim of this study is to assess validity of the ETXY Multifunctional trainer (ProDelphus, Olinda, Pernambuco, Brazil), a bench-top dry-lab model for simulation of cystoscopy and intravesical injections of Botulinum Toxin A (BTX-A) injections, in terms of educational value, feasibility and acceptability as well as evaluating the use of fresh frozen cadavers for intravesical BTX-A injections. Prospective study with novice trainees and urologists (n=58) trained by experts (n=14) in a 30-min hands-on training session in intravesical administration of BTX-A over 6 training sessions throughout one year. Outcome measures were demonstrated through distribution and analysis of evaluation surveys on a 5-point Likert scale. There were 56 participants (96.6%) believed that the model has a role in training for the procedure. Participants also reported the training being an important confidence-booster for performing BTX-A injections (mean: 4.05/5) and useful for teaching procedural steps (mean: 3.89). Experts highly rated the realism of the simulator especially in simulation of needle penetration (mean: 3.98) and delivery (mean 4.03). Fresh frozen cadavers had a mean realism rating of 4.54 and participants affirmed that they should be routinely used for training and assessment (mean: 3.92). This study demonstrated face and content validity in addition to establishing the feasibility and acceptability of the ETXY Multifunctional model in the training of intravesical BTX-A administration. Additionally, the simulator demonstrated educational value and fresh frozen cadavers were shown to be the preferred simulation modality for this procedure. Further evaluation in randomised controlled studies is needed to demonstrate higher evidence quality.
