Holographic reconstruction technology used for intraoperative real-time navigation in robot-assisted partial nephrectomy in patients with renal tumors: a single center study

Abstract

Background: To explore the efficacy and advantages of real-time navigation using holographic reconstruction (HR) technology combined with da VinciTM robotic system for partial nephrectomy (PN) in patients with renal tumor. Methods:The clinical data of 41 patients with totally intrarenal tumors receiving robot-assisted partial nephrectomy (RAPN) from April 2018 to October 2020 in our department were collected and retrospectively analyzed. All operations were performed by the same surgeon. HR technology and three-dimensional (3D) reconstruction techniques were applied for real-time navigation to resect tumors using the da VinciTM robotic system. The relevant clinical parameters and surgical outcomes of the patients were recorded and analyzed.Results: HR technology allowed accurate evaluation of tumors, renal hilus vessels, and surrounding organs during the operation. With real-time navigation HR, all cases were performed by RAPN. The mean operative time was 115.3±20.3 (range, 70-153) minutes, and the warm ischemia time (WIT) was 18.7±3.9 (range, 13-28) minutes. The estimated blood loss (EBL) was 98.8±18.7 (range, 60-141) mL.Negative surgical margins were reported in all cases. Patients with absence of grade ≤1 Clavien-Dindo complications. Compared with the clinical outcomes of standard RAPN, as reported in the literature, HRassisted technology reduced the mean operative time, the WIT, and the EBL in patients undergoing RAPN. Therefore, combining HR with robotic abdominal surgery can enhance the efficiency of locating blood vessels and allow for more accurate resection of tumors.Conclusions: As a novel and promising computer digital technology, HR can significantly improve the success of RAPN operations. This retrospective study demonstrated that HR-assisted operations resulted in shorter operation times and less perioperative complications and were thus safer and more effective in patients with renal tumors compared with RAPN not used HR.

Quality of Life and Psychological Distress among Patients with Small Renal Masses

“…Future prospects regarding treatment options for renal cancer are mainly evolving in the direction of digital imaging. Three-dimensional reconstruction seems to be useful for optimization of partial nephrectomies [ 29 ] and digital technology navigation during surgery can decrease operative time and complications [ 30 ] thus further reducing the burden of a surgical treatment. Advances in the field of percutaneous ablation could lead to an expansion of this technique especially in patients not suitable for surgical treatment who are not willing to undergo AS.…”

Patient‐specific simulations and navigation systems for partial nephrectomy

“…Surgeons that perform RAPN greatly desire an augmented reality‐based navigation system 37 . 3DVR images are mostly used for navigation during RAPN surgery, although holograms were used in some studies 38,39 . In da Vinci surgery, it is common to use TilePro to display 3DVR images.…”
