The Future of Penile Prosthetic Surgical Training Is Here: Design of a Hydrogel Model for Inflatable Penile Prosthetic Placement Using Modern Education Theory.

BACKGROUND:There is a significant need for a non-biohazardous, educational platform to equip and maintain the surgical skills required by urology trainees and low-volume implanters for inflatable penile prosthetic (IPP) placement. AIM:To design and develop an anatomic, hydrogel-based simulation platform for training and evaluate IPP placement using modern education theory. METHODS:The backward design concept was used as a framework in the design and development of an IPP simulation platform. Steps included delineating requirements from a physicians' perspective, translating requirements into engineering tasks (deliverables), developing a prototype, and pilot validation. Using a combination of 3-dimensional printing and hydrogel casting, a genitourinary tract model was constructed to replicate the appropriate steps of IPP placement guided by expert feedback. Full-immersion IPP simulations were performed through both infrapubic and penoscrotal approaches by 4 expert surgeons under operative conditions. Questionnaires evaluating the simulation's realism, value as a training tool, and further recommendations were completed. OUTCOMES:Using backward design educational pedagogy, a high-fidelity, full-procedural IPP simulation was fabricated and verified as an adequate educational tool for training and assessment. RESULTS:An expert consensus on the anatomic landmarks, steps and substeps, instruments, and errors to be included in the model was reached using a hierarchical task analysis and was successfully translated into a prototype hydrogel model. Experts performed all appropriate steps of IPP surgery and rated the simulation highly in terms of its realism and value as a training tool. On average, experts agreed that the model could function as a training tool, assessment tool, prerequisite for IPP accreditation, and requirement before live surgery. Experts stated they would have their trainees ideally complete an average of 1.75 models before live surgical training. All experts believed an operative checklist would be an ideal assessment tool.
