Low-cost simulation models in Urology: a systematic review of the literature

INTRODUCTION: Simulation models have been found to be effective and valid for training in Urology. Due to increasing costs of surgical training, there is a need for low-cost simulation models to enable Urology trainees to improve their skills MATERIAL AND METHODS: A literature review was performed using the PubMed and Embase databases until March 2020. A total of 157 abstracts were identified using the search criteria, of which 20 articles were identified describing simulation models for Urology training. Articles reviewed described simulation models created from materials costing less than $150. Data was extracted from the relevant articles in order to critically assess each paper for validity, ease of construct and educational impact. RESULTS: Models were found pertaining to suprapubic catheterization (6), cystoscopy (3), percutaneous nephrolithotomy (5), scrotal examination (1), circumcision (1), ureteroscopy (1), transurethral resection of the prostate and bladder (2), and open prostatectomy (1). 18/20 (90%) assessed for either face, content, or construct validity. None of the papers evaluated assessed for transferability of skills to performance in real patients. CONCLUSIONS: A plethora of low-cost simulation models for urological procedures are described in the literature, many of which can be easily constructed from cheap and accessible materials. However there is a need for further efforts to validate or assess for transferability of skills to clinical practice.
