Radical prostatectomy (RP) is a definitive surgical therapy for localized prostate cancer. Evidence suggests that the poor ergonomics of surgeons during RP may lead to work-related musculoskeletal disorders and loss of productivity. Since each surgery modality has its physical demands, we compared the ergonomic risk between laparoscopic (LRP) and robotic-assisted (RARP) radical prostatectomy. The study assessed the posture of 10 urological surgeons during LRP and RARP surgeries with the Rapid Entire Body Assessment (REBA) scale. We found that the RARP approach resulted in lower REBA scores over the LRP procedure. Robotic surgery improves body posture for the urological surgeon like in other medical specialties. However, the surgeons display harmful postures in both surgeries.
