Patient-specific three-dimensional (3D) printed model could be useful during operation. METHODS Nine patients successfully underwent partial nephrectomy with complete excision of the suspicious renal cell carcinoma by open (N=7) or robotic assisted laparoscopic (N=2) approach. Volumetric CT examinations were performed to evaluate renal mass. A-view software (In-house software, Asan Medical Center, Seoul, South Korea) has been used to reformat the renal anatomy, renal mass and measure tumor volume. The virtual resection simulation followed an adequate safety margin with 5 mm distance away from the renal mass. 3D printed kidney model was fabricated with Objet 500 CONNEX3 3D printer (Stratasys CO, USA) with high quality color resolution and Any desired color can be obtained with mixture of the three base colors □ translucent, cyan, magenta. With a clear and translucent resin the kidney model was constructed with different colors. RESULTS The renal mass could be visualized and differentiated from blood vessels and renal collecting system in this model. (Figure) The mean tumor size was 2.2 cm, tumor volume, 7.65 cm3, expected remained renal tissue volume 169 cm3 (94%) and the RENAL nephrometry score ranges 5–9. Mean ischemic time and mean operation time were 16 min and 190 min. 3D printed kidney has an advantage that it enables them to obtain an incision line and depth of dissection. Additionally, it could measure tumor volume, expected resected renal tissue volume and predict remain renal parenchymal volume after operation. So these model could useful for predict renal function after nephrectomy. When we explain the operation procedure with 3D printed kidney model to patients, satisfaction of patients was increased and their concern was decreased. CONCLUSIONS The use of the simulated patient-specific 3D printed kidney model facilitates the surgical procedure, due to enhancement of preoperative planning and intraoperative orientation of risk structure and target tissue, and may improve surgical outcome. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e241 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Yoon Soo Kyung More articles by this author Namkug Kim More articles by this author Dalsan You More articles by this author Jeong In Gab More articles by this author Jun Hyuk Hong More articles by this author Choung-Soo Kim More articles by this author Myungchan Park More articles by this author Chanwoo Lee More articles by this author Sangjun Yoo More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
