Four surgeons participated: two with extensive prior robotic experience (&gt;500 Da Vinci Surgical System [Intuitive Surgical Inc., Sunnyvale, CA, USA] RPs) and two with laparoscopic but no robotic background, operating under structured proctoring. Outcomes included objective measures such as console time or novel hand motion volumetry. Proficiency was defined by Learning Curve Cumulative Sum (LC\u2010CUSUM) analysis with thresholds of console time &lt;165\/180\u2009min (without\/with lymphadenectomy) and absence of significant positive surgical margins.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 151 consecutive patients were included. Pre\u2010 and postoperative characteristics were comparable across surgeons. There were clinically and statistically significant improvements in operative time and hand motion metrics with increasing experience. Proficiency was achieved after 23 cases by experienced surgeons and after 37 by novel surgeons. The overall positive margin rate was 27.8%, with only two cases exceeding the \u22653\u2009mm threshold in nerve\u2010sparing procedures. Major complications (Clavien\u2013Dindo Grade \u2265III) only occurred in four (2.6%) patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Surgical proficiency in Versius\u2010assisted RP was achieved in &lt;40 cases, particularly among surgeons with prior robotic experience.
