摘要

The EDGE single-port endoscopic surgical robot (SP1000), specifically designed for urological, gynecological, thoracic and general surgical procedures, has recently been applied in various operations. However, there is currently a lack of evidence comparing its performance with the Da Vinci Xi robot system. This study aims to compare the technique and perioperative outcomes of radical prostatectomy (RP) performed with EDGE SP1000 versus the Da Vinci Xi robot system. Data were collected from radical prostatectomy cases performed at Anhui Medical University from March 2025 to December 2025. 101 patients underwent radical prostatectomy using EDGE SP1000 and 102 patients using Da Vinci Xi were operated on using the Da Vinci Xi system. A 1:1 propensity score matching method was applied to compare the two groups both before and after matching based on age, body mass index, prostate size, prostate specific antigen (PSA) level, and Gleason score. We primarily evaluated the surgical efficacy of the two robotic systems by comparing perioperative clinical data. In the matched surgery groups (EDGE SP1000 vs. Da Vinci Xi), there were no significant differences in age (68.6 years vs. 69.3 years; p = 0.59), PSA (10.3 ng/ml vs. 10.1 ng/ml; p = 0.93), Gleason score (7 vs. 7; p = 0.41) and prostate volume (38.0 cm3 vs. 37.4 cm3; p = 0.81). All procedures were completed successfully without any conversion to open surgery. There was no significant difference in the total operative time between the two groups (136.6 vs. 129.0 min; p = 0.14). No major intra or postoperative complications were observed in either group. Positive surgical margin rates were no significant (36% vs. 41%; p = 0.41). Despite the design variations between the two robotic systems, there were no significant differences in the final surgical outcomes. The EDGE SP1000 system serves as a viable option for radical prostatectomy.
