About this trial
Accurate preservation of neuro-vascular bundles is crucial in guaranteeing erectile function recovery after robot assisted radical prostatectomy (RARP). However, the nerve sparing approach is associated with higher rates of positive surgical margins (PSM) at final pathology. Augmented reality (AR) RARP was previously associated with a 10-15% reduction in the rates of PSMs in two retrospective series. However, prospective studies are needed to demonstrate clinical utility and to validate these technologies. The hypotheses of this study are that: 1) AR RARP reduces the rates of PSMs, if compared to standard approach; 2) AR RARP can guarantee a more accurate preservation of neurovascular bundles and, in consequence, a greater recovery of erectile function; 3) the lower rates of PSMs will translate in greater oncological control of the disease.
