Introduction & Objective : Nowadays, in prostate cancer surgical procedures, oncological and functional outcomes are equally important. The improvement of new technologies and minimally invasive surgery translated into a more tailored approach. Nevertheless, the standard preoperative imaging still remains the routine tool for surgical planning and intraoperative decision-making, requiring an intraoperative mental imagination. In this setting, the 3D rendering and the intraoperative surgical navigation allow to overcome the limitation of this «building in mind» process. Aim of this study is to present our preliminary experience with augmented reality robot-assisted radical prostatectomy (AR-RARP).


Methods : According to dedicated protocol, from June 2017 to March 2018 patients candidate to RARP were enrolled and underwent high resolution (1-mm slices) multiparametric Magnetic Resonance (mpMRI ). 3D reconstruction obtained was integrated in the robotic console to perform AR-RARP. According to the MRI-reconstruction staging, patients with cT2 PCa, underwent intrafascial nerve sparing (NS): a mark was placed at prostate capsule to indicate the underlying intraprostatic lesion; in case of cT3, standard NS AR-RARP was scheduled and AR-guided biopsies at the level of suspected extracapsular extension (ECE) were performed. Prostate specimens were scanned to assess the 3D model concordance.


Results : 25 patients underwent intrafascial NS technique (cT2) and 25 underwent standard NS + selective biopsy of suspected ECE (cT3). Final pathology confirmed clinical staging. Positive surgical margins rate was 27% overall and 4.2% in pT2. The location of marked intra-prostatic lesions were confirmed at final pathology. In suspected ECE, AR-guided selective biopsies confirmed the ECE location, with 20/25 (80%) positive biopsies for PCa. Prostate specimens were scanned finding a good overlap. The mismatch between 3D reconstruction and scanning ranged from 1 to 5 mm. In the 85% of the entire surface it was < 3 mm.


Conclusions : In our preliminary experience, AR-RARP is safe and effective. The exactitude of 3D reconstruction seemed to be promising. This technology has still limits: the virtual models are rigid and they need manually orientation. Future collaborations with bioengineers are mandatory to overcoming
