Robot-assisted radical prostatectomy with the Hugo™ robot-assisted surgery system: A single-center initial experience in Japan

Background: Recently, various novel robotic systems have been put into clinical use. The aim of the present study was to assess the perioperative outcomes of robot-assisted radical prostatectomy (RARP) using the Hugo™ RAS system, one of brand-new robot-assisted surgical platforms. Methods: We performed RARP with the Hugo™ RAS system in 13 cases of localized prostate cancer (PCa) between August 2023 and February 2024 at our hospital. The perioperative outcomes of these 13 patients were assessed. Results: The median operative and console times were 197 (interquartile range [IQR], 187–228) and 134 min (IQR, 125–157), respectively. The median docking time was 7 min (IQR, 6–10), and the median estimated blood loss was 150 mL (IQR, 80–250). The vesical catheter was removed on postoperative day 6 in all cases. A positive surgical margin was observed in one patient (7.7%), and none experienced major perioperative complications, defined as Clavien–Dindo classification ≥3. The median postoperative length of stay was 8 days (IQR, 8–8.5). Conclusions: This was the first study to focus on RARP using the Hugo™ RAS system in Japan. Although further investigations should be conducted to assess the long-term oncological and functional outcomes, the Hugo™ RAS system could provide safe and favorable perioperative outcomes for patients with localized PCa undergoing RARP.
