PD08-02 IMMERSIVE VIRTUAL-REALITY FOR PERCUTANOUS NEPHROLITHOTOMY: IMPACT ON PATIENT EDUCATION, SURGICAL PLANNING AND TREATMENT OUTCOME

Abstract

INTRODUCTION AND OBJECTIVES:Percutaneous nephrolithotomy (PCNL) requires urologists to have detailed knowledge of the stone and its relationship to the renal anatomy. Immersive virtual reality (iVR) provides patient-specific 3D models that might be beneficial in this regard. Our objective is to evaluate the impact of iVR on surgeon's preoperative planning, clinical outcomes, and patient education.METHODS:Four endourologists used iVR models (Figure 1) to acquaint themselves with the renal anatomy prior to PCNL in 25 patients. iVR renderings were also viewed by patients using the same head-mounted Oculus Rift display (Facebook Inc.). Using a Likert-type scale (1=strongly disagree to 5=strongly agree), surgeons rated their understanding of the anatomy after viewing CT images only and then after the iVR experience; using a similar Likert-type scale, patients recorded their experience with iVR. Next, iVR patients were matched with 25 retrospective non-iVR patients with similar age, ASA, BMI, stone burden, gend...
