Design, Development, and Validation of a First, Low-cost, Three-dimensional (3D) Printed Optical Urethrotomy Simulation Model.

OBJECTIVE: To develop and validate a low-cost, portable, and reusable simulation model for optical internal urethrotomy (OIU) training. METHODS: A 3D-printed low-cost simulation model for OIU was designed locally and the final model was evaluated by trainees and trainers at the urology boot camps (UK, Belgium, Portugal, Poland). Participants were asked to complete a questionnaire, using a 6-item 5-point Likert Scale, to assess the model's anatomic realism. RESULTS: A total of 27 trainees and 9 trainers evaluated the model. The model's anatomy and color were rated as the most realistic features, with 88.9% and 11.1% of respondents rating them as good and excellent, respectively. There were no significant differences between consultants and trainees in their assessment of any of the simulation properties of the OIU model. CONCLUSION: Our study introduces an innovative, lifelike, and cost-effective simulation model for OIU training. Our model provides a realistic simulation of OIU. We feel that our low-cost and reusable model fills the gap in simulation-based training for young trainees in urology.

Creation of a novel ex vivo 3D printed ileal conduit task trainer for teaching conduitoscopy skills.

OBJECTIVES: To perform endoscopy in patients with urinary diversions requires specific endoscopic skills, which can currently only be gained in clinical practice. We created a 3D printed ex vivo ileal conduit model (stoma and conduit with ureters and 2 kidneys) to simulate "conduitoscopy" and evaluated the realism and limitations of the model. METHODS: Accurate anatomical features were represented using an appropriate reusable design, realistic mechanical qualities with several material types, and 3D-printed components. Different models of bowel and ureters were assessed by the subject-matter experts (SME). The final ileal conduit model (Wallace 1 type anastomosis) was evaluated by 18 SMEs. RESULTS: Most experts gave their approval to the view of the stoma, as well as the appearance of the bowel, ureteric, and pelvicalyceal systems. A total of 72.1% of SMEs approved the ureteric endoscopic view compared to about 66% who accepted the endoscopic examination of the bowel. The model's overall appearance was good for 61.1% and excellent for 38.8% of experts. CONCLUSION: Conduitoscopy simulation training can now be facilitated using our novel and unique cutting-edge 3D printed model. We created a model that is highly anatomically accurate and workable. In our study, anatomical and visual realism was demonstrated. The next step would be increasing the length of the conduit and conduct a validation study.

A Pilot Study Evaluating a Virtual Reality-Based Nontechnical Skills Training Application for Urology Trainees: Usability, Acceptability, and Impact.

OBJECTIVE: This study aimed to develop and evaluate a virtual reality (VR)-based nontechnical skills (NTS) training application for urology trainees and assess its effectiveness in improving their skills and confidence. DESIGN: A mixed-methods study was conducted to develop and evaluate a VR-based NTS training application for 32 urology trainees. The development process involved collaboration with 5 urology experts, 2 medical education specialists, and a human factors researcher. The study evaluated the application's usability, acceptability, and efficacy through 3 phases: scenario development with expert feedback integration, storyboarding and creation processes with facilitators and urology trainees, and a final evaluation by trainees. SETTING: The data were collected during a 4-day urology boot camp in October 2022. PARTICIPANTS: Thirty-two urology trainees participated in the study and completed 2 VR scenarios designed to enhance their NTS skills RESULTS: The System Usability Scale (SUS) showed a moderate usability score of 66. The Training Evaluation Inventory (TEI) and additional feedback demonstrated positive effects on trainees' learning and confidence in their NTS abilities. Most participants found the application easy to use, and effective and they expressed interest in using similar VR applications for other aspects of surgical training. CONCLUSIONS: VR-based NTS training applications show potential for enhancing urology trainees' nontechnical skills. The integration of expert feedback and immersive technology offers a promising, accessible, and cost-effective solution to the challenges of delivering NTS training. Future research should explore the long-term impact of VR-based NTS training on trainees' performance and patient outcomes and consider incorporating advanced AI technologies for personalized and dynamic learning experiences.
