Novel Three-Dimensional Workstation System for Intraoperative Navigation in Robot-Assisted Partial Nephrectomy: A Single-Arm Study

Detailed knowledge of the anatomical relationships between renal tumors, vascular structures, and the urinary tract is required to perform robot-assisted partial nephrectomies (RAPNs) successfully. Recent improvements in imaging modalities include computed tomography and magnetic resonance imaging. In addition, 3-dimensional (3D) workstation systems for intraoperative navigation have also been developed. This report introduces a novel 3D workstation system for intraoperative navigation while performing RAPN called “Atrena.” Atrena is equipped with multiple methods for the stereoscopic viewing of 3D images. Furthermore, Atrena operates on a tablet. Therefore, using Atrena in RAPN enables the rotation and enlargement of stereoscopic 3D images through manipulations on the tablet's screen. Atrena was successfully used for intraoperative navigation in initial 15 cases of RAPN with high trifecta achievement ratios. We believe that this novel 3D workstation system, “Atrena,” is beneficial in performing RAPN and enhances its success. We also believe that Atrena may be useful as an educational tool for medical staff.
