Outline of Final Research Achievements

The aim of this study is to establish surgical procedures to perform robotic partial nephrectomy using image-guidance and 3-dimentional (3D) models. Partial nephrectomies need oncological outcome and renal function preservation.
We established the 3D model in which a tumor and renal vessels were classified with different colors. In addition, I depicted the renal artery in details about the relations with tumor using 3D construction software. Using them, we established the simulation system in which we can evaluate tumors from every angle before operation. Furthermore, with this 3D construction image, we established the navigation system by the image guide when we perform robotic partial nephrectomies. And we performed robotic partial nephrectomies with this navigation system practically.
