BACKGROUND Virtual reality simulators allow trainees to perform repeated practice and provide objective dexterity metrics regarding their performance, which means that virtual reality-based surgical training is becoming a vital part of initial learning of basic laparoscopic surgical skills. However, its educational role in learning advanced procedures remains undetermined. We evaluated the validity of the laparoscopic radical nephrectomy module of the LapVision virtual reality simulator. METHODS Urologists, medical students, and a junior resident voluntarily participated in the present study, and they performed training with a laparoscopic left radical nephrectomy module. For construct validation, dexterity metrics calculated in the simulator and the mean score of Global Operative Assessment of Laparoscopic Skills evaluated by 2 experts' video review were compared according to the certification of Japanese Endoscopic Surgical Skill Qualification or previous surgical experience. RESULTS Ten experts (≥ 50 laparoscopic surgeries), 9 intermediates (11-49), and 14 novices (0-10) voluntarily participated in the present study. Regarding the construct validity, there was a significant difference in the total number of errors, blood loss, and Global Operative Assessment of Laparoscopic Skills score among the groups for both the Endoscopic Surgical Skill Qualification status and previous surgical experience. CONCLUSIONS The present study demonstrated good construct validity for the LapVision nephrectomy module. Furthermore, global skill assessment was possible by experts' reviews, which indicates the usefulness of the virtual reality procedural module as a skill assessment tool. Virtual reality-based procedural simulation has marked potential to become a vital part of integrated laparoscopic training programs.
