A Randomized Comparison of 2 Robotic Virtual Reality Simulators and Evaluation of Trainees' Skills Transfer to a Simulated Robotic Urethrovesical Anastomosis Task

Abstract

Objective To determine, via a randomized comparison study, whether robotic simulator-acquired skills transfer to performance of a urethrovesical anastomosis (UVA) on a 3-dimensional-printed bladder model using the da Vinci Robot. Materials and Methods Medical students, surgical residents, and fellows were recruited and divided into 2 groups: Group 1 (G1) (junior trainees) and Group 2 (G2) (senior trainees). Participants were randomized to identical simulator training curricula on the dV-Trainer (dV-T) or da Vinci Surgical Skills Simulator (dVSSS). Participants then completed a UVA task on a 3-dimensional-printed bladder model using the da Vinci robot. Three blinded expert robotic surgeons rated videotaped performances of the UVA task using validated assessment tools, namely, the Global Evaluative Assessment of Robotic Skills (GEARS; overall procedure) and Robotic Anastomosis Competence Evaluation (RACE; specific to UVA). Results Thirty-nine participants (G1 = 23 and G2 = 16) completed the study. Participants in G2 had significantly more simulation and surgical experience compared with G1 (P
