In a randomized, multi-center phase III trial comparing the clinical outcomes of robot-assisted v open laparoscopic radical prostatectomy in 326 men with newly diagnosed early-stage prostate cancer there was no difference in the eventual clinical outcomes.
The researchers found that the urinary and sexual functions of men in both groups were similar at 12 weeks post surgery. They also found that the positive surgical margin rates were not significantly different between the two groups.
The researchers concluded that the robot-assisted laparoscopic radical prostatectomy has similar clinical outcomes to those achieved with an open radical prostatectomy.
