Abstract
PURPOSE: Surgical simulation has benefited from a surge in interest over the last decade because of the increasing need for a change in the traditional apprenticeship model of teaching surgery. Open surgery for ureteropelvic junction (UPJ) poses unique training challenges owing to smaller workspaces, and finer sutures used that require increased surgical dexterity when compared with adult analogues. We describe the development and face validation of a low-cost training simulator for open dismembered pyeloplasty. MATERIALS AND METHODS: The simulator is built with A4 Kraft envelopes, catheter tip syringe filled with 30mL of air, tape, 260 modeling balloon, and 11-in party balloon. Evaluation of the device is based on an evaluation form including 11 items on a 5-point Likert-type scale. Thirty-one departments of pediatric surgery in France were contacted and received a pack containing 4 to 10 devices, already set up and ready for use, a tutorial and an evaluation form. Candidates were stratified according to their level of expertise. RESULTS: A total of 180 devices were sent. Procedures on the device were performed 118 times (65%) by expert surgeons (n = 44), fellows (n = 25), and residents (n = 49). Statistically significant difference was noted for 4 items (anatomy, model exposition, UPJ resection, and difficulty) for the 3 levels of expertise. The global score evaluation for realistic items, face validity, and usability was 4.2 (range: 1-5). CONCLUSION: This low-cost model is evaluated as an efficient tool for UPJ teaching and training. It shows promise as an educational tool.
