The study is a prospective randomized blinded cohort study. Patients who meet eligibility criteria will be randomly assigned to undergo RARP at a pneumoperitoneum pressure of 12mm Hg or 8mm Hg. This will be done by computer generated randomization protocol. Surgeon and patients will be blinded to the pneumoperitoneum pressure used. A cover will be placed over the AirSeal™ system so that the surgeon(s) are not able to visualize the pneumoperitoneum used during the procedure. The remainder of the procedure will be carried out based on current standard of care.
