Robotic prostatectomy has progressively emerged as an oncologic and functional equivalent to the gold standard of open surgery, with minimally invasive advantages such as a short hospital stay, less blood loss and early return to complete activity. However, mastering the technique remains delicate and requires regular and sufficient practice to reach the aforementionned advantages. Because of the marketing pressure, there is now a plethora of robots available in some areas. This will lead to the multiplication of occasional operators, whose negative impact on the efficiency of the procedure is demonstrated. The solution may be that of aviation: improve skills on a simulator in order to correctly perform clinically. It is now necessary to stimulate the elaboration of such a simulator.
