The exponential adoption of minimally invasive robot-assisted radical prostatectomy (RARP) has been remarkable and unprecedented. According to unverified estimates from the Da Vinci surgical system manufacturer (Intuitive Surgical, Sunnyvale, CA) over 80% of radical prostatectomy within the US were performed robotically in 2010. This dramatic shift in radical prostatectomy practice patterns occurred despite the lack of evidence of high quality of the method, not yet demonstrating its oncology benefits, safety or cost effectiveness compared to open surgery.
