Purpose: We aimed to evaluate the effect of self-training using a virtual reality head-mounted display simulator on the acquisition of surgical skills for holmium laser enucleation surgery. Methods: Thirteen medical students without surgical skills for holmium laser enucleation of the prostate were trained using multimedia to learn the technique via simulator manipulation. Thereafter, participants performed the technique on a virtual benign prostatic hyperplasia model A (test A). After a 1-week wash-out period, they underwent self-training using a simulator and performed the technique on model B (test B). Subsequently, participants were asked to respond to Training Satisfaction Questions. Video footage of hand movements and endoscope view were recorded during tests A and B for later review by 2 expert surgeons. A 20-step Assessment Checklist, 6-domain Global Rating Scale, and a Pass Rating were used to compare performance on tests A and B. Results: Thirteen participants completed both tests A and B. The 20-step Assessment Checklist and 6-domain Global Rating Scale evaluation results showed significantly improved scores in test B than in test A (P<0.05). No evaluator rated participants as passed after test A, but 11 participants (84.6%) passed after test B. Ten participants (76.9%) indicated that the simulator was helpful in acquiring surgical skills for holmium laser enucleation of the prostate. Conclusions: The virtual reality head-mounted display holmium laser enucleation of the prostate simulator was effective for surgical skill training. This simulator may help to shorten the learning curve of this technique in real clinical practice in the future.
