The cost of radical prostatectomy: retrospective comparison of open, laparoscopic, and robot-assisted approaches

New technologies are regularly being used for surgical treatment of prostate cancer, however the cost associated is often a secondary issue. We assessed the operative costs incurred by using the daVinci robot assisted prostatectomy (RAP) method compared to pure laparoscopic radical prostatectomy (LRP) and open radical prostatectomy (ORP). We retrospectively analyzed three techniques of radical prostatectomies: ORP, LRP, and RAP (n = 70, 57, 106, respectively). The mean patient age was 53.6, 57.6, and 60 with a mean preoperative prostate specific antigen (PSA) of 7.2, 8.4, and 6.6, respectively. The mean Gleason score was 6. Operative cost was measured for each patient. Charts were reviewed to assess individual patients postoperative requirements, and hospital length of stay (LOS). Intraoperative data show costs to be higher with the RAP and LRP compared to open surgery. Average total operating room (OR) costs per case were $5410, $3876, and $1870 for RAP, LRP, and open prostatectomy, respectively. However when comparisons are made in the postoperative period with regard to LOS, there is a significant advantage of the RAP and LRP groups over open surgery (P < 0.05). Intraoperative costs are highest for RAP. Both LRP and RAP are associated with a shorter hospital stay.
