Purpose: This study compared the perioperative parameters and early functional outcomes between robot-assisted radical prostatectomy (RARP) and laparoscopic radical prostatectomy (LRP) at a urological laparoscopic center. Materials and Methods: Between January 2006 and May 2017, 242 patients underwent endoscopic radical prostatectomy (LRP for 208 cases; RARP for 34 cases). Patients who were followed up > 12 months were included in the study. Propensity score-matched groups of patients who underwent LRP or RARP were created based on age, body mass index, history of diabetes mellitus, history of smoking, preoperative prostate-specific antigen level, clinical T status, risk group classification, American Society of Anesthesiologists score, and whether the nerve-sparing technique was performed. Results: There were no significant differences in the blood transfusion rate, surgical margin status, length of stay, catheterization time, or days to oral intake for both procedures. Although RARP is more time-consuming, it provided significant benefits regarding the yield of dissected lymph nodes (19 vs. 9; P < 0.001) and early urinary continence recovery (i.e., continence rates after 1 month [56.2% vs. 21.9%; P = 0.006] and after 3 months [84.4% vs. 53.1%; P = 0.001]). No difference was observed for early complications, although the RARP group had more late complications. Conclusion: Our experience indicated that RARP could provide less blood loss and faster recovery of urinary continence and yield more dissected lymph nodes compared to LRP. Further studies are needed to determine whether the long-term clinical, functional, and oncological outcomes are superior.
