In contrast, virtual reality (VR) allows the user to visualize and interact with the anatomy in a 3D environment. Herein, we present our initial experience with VR in comparison to CT alone for patients undergoing PCNL. METHODS An observational prospective study design was used to recruit 15 urolithiasis patients scheduled for PCNL. Using 3D Slicer, CT scans were used to create 3D models, which were subsequently uploaded to a VR software for viewing with a head-mounted display (Figure 1). Four experienced surgeons judged their pre-operative understanding (0 = poor; 10 = excellent) of the pertinent anatomy using CT alone vs. CT with VR. Surgeons and patients recorded their experience with the VR technology using a Likert-type scale (1=strongly disagree to 5=strongly agree). RESULTS For the surgeons, the VR model provided a significantly improved understanding of the location and orientation of the stone, and the optimal calyx of entry compared to CT imaging alone (Table 1). After viewing the VR model, surgeons strongly agreed: it improved their confidence with the surgery (4.8/5), was a valuable surgical tool (4.7/5), and would be useful for teaching residents (4.9/5). On the post-operative assessment, the VR model assisted the surgeon in navigating the anatomy (4.2/5), and correlated well with the renal anatomy (4.6/5). The VR model altered the surgical approach in 7 (47%) cases. Patients strongly agreed that the VR experience: improved their understanding of their stone (4.9/5), and reduced their anxiety regarding their upcoming surgery (4/5). CONCLUSIONS In this early experience, VR technology helped the surgeon to better understand the renal anatomy and resulted in an altered approach in up to 50% of cases. In addition, the VR experience improved patient comprehension and comfort with the surgery. © 2018FiguresReferencesRelatedDetails Volume 199Issue 4SApril 2018Page: e345 Advertisement Copyright & Permissions© 2018MetricsAuthor Information Egor Parkhomenko More articles by this author Shoaib Safiullah More articles by this author Sartaaj Walia More articles by this author Michael Owyong More articles by this author Cyrus Lin More articles by this author Mitchell O’Leary More articles by this author Ryan James More articles by this author Roshan Patel More articles by this author Kamaljot Kaler More articles by this author Jaime Landman More articles by this author Ralph Clayman More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
