PD16-06 PATIENT-BASED 3D PRINTED ORGAN MODEL PROVIDES TANGIBLE SURGICAL NAVIGATION: A NOVEL AID TO CLAMPLESS PARTIAL NEPHRECTOMY

INTRODUCTION AND OBJECTIVES: To incorporate a computer-assisted volumetric assessement of potential spared paranchyma from preoperative CT scans to predict chronic kidney disease (CKD) at 6 months from extirpative renal surgery. METHODS: We performed a retrospecitve analysis of radical (RN) or partial nephrectomy (PN) patients with compatable CT scans from our institution. We used Vitrea v.6.3 computer software program (Vital Images, Minnetonka, MN) to create a 3D volume of the tumor, 1 cm margin, ipsilateral kidney (Figure), and contralateral kidney (cm3). Primary outcome analyzed was development of postoperative CKD (estimated glomerular filtration rate
