[Correspondence] Assessing robot-assisted laparoscopic prostatectomy

In the phase 3 clinical trial by John Yaxley and colleagues,1 the only significant differences between radical retropubic prostatectomy and robot-assisted prostatectomy were observed in hospital stay, blood loss, duration of surgery (minutes), time in operating room (minutes), and stress levels, which were all lower in the robot-assisted surgery group. However, the authors did not perform a cost-benefit and cost-effectiveness study, which could be very interesting because there are no significant differences in oncological or functional outcomes.
