Comparison of Surgical Outcomes Between the hinotori™ and da Vinci® Robotic Systems in Robot-Assisted Sacrocolpopexy - A Retrospective Study

Aug 27, 2026

Retrospective comparison of robot-assisted sacrocolpopexy for pelvic organ prolapse evaluated whether the newly adopted hinotori™ system can match the established da Vinci® platform in perioperative performance. A single-center cohort of 23 patients (September 2023–December 2024) assessed operative time, console time, and stepwise procedural durations. Although overall patient profiles were similar and console time showed no statistical difference, operative time and specific steps—robot roll-in to console start and posterior mesh fixation—were longer with hinotori™, with otherwise comparable perioperative outcomes.

Materials and methods This single-center retrospective study included 23 patients who underwent RASC between September 2023 and December 2024. Eleven patients underwent surgery with the hinotori™ system (h-RASC), and twelve with the da Vinci® system (d-RASC) . Operative time, console time, and stepwise procedural durations were evaluated. Results Patient characteristics were comparable between groups. Although console time showed no significant difference, operative time tended to be longer in the h-RASC group (275 vs. 242 minutes; p = 0 .056), without reaching statistical significance. The time from robot roll-in to console start (16 vs. 7 minutes; p = 0 .004) and posterior mesh fixation (16 vs. 12 minutes; p = 0 .001) was significantly longer with the hinotori™ system. Other perioperative outcomes were similar. Conclusion RASC using the hinotori™ system produced comparable perioperative outcomes to those of the da Vinci® system, although some procedural delays were observed during the initial implementation period. Categories: Urology Keywords: davinci surgical system, hinotori surgical system, operative time comparison, pelvic organ prolapse (pop), robot-assisted sacrocolpopexy Introduction Pelvic organ prolapse (POP) is a condition in which pelvic organs such as the uterus, bladder, or rectum descend into the vagina due to weakness of the supportive pelvic tissues. Patients commonly experience symptoms such as a sensation of pelvic pressure, a vaginal bulge, urinary dysfunction, and in severe cases, pain and bleeding. These symptoms can significantly impair quality of life. The surgical management of POP aims to restore anatomical structure and improve function. Of the various techniques, abdominal sacral colpopexy is considered the gold standard, offering superior anatomical and functional outcomes compared to transvaginal approaches [1-3]. Laparoscopic sacrocolpopexy (LSC) is a less invasive alternative associated with reduced blood loss and shorter hospitalization. However, it remains technically demanding with a steep learning curve [4,5] . Robotic-assisted sacrocolpopexy (RASC), particularly when utilizing the da Vinci® surgical system (Intuitive Surgical, Inc., Sunnyvale, California, US), was introduced to address these challenges by enhancing precise surgical procedures and reducing surgeon fatigue. Meta-analyses have shown that RASC results in lower intraoperative complication rates and comparable anatomical success to LSC, albeit with increased operative time [6,7] .

FAQs

What was the main objective of this study?

To determine whether the hinotori™ surgical system, during early clinical adoption, achieves perioperative outcomes comparable to the da Vinci® system for robot-assisted sacrocolpopexy.

How were patients grouped and what period was analyzed?

The single-center retrospective study included 23 patients: 11 underwent surgery with hinotori™ (h-RASC) and 12 with da Vinci® (d-RASC), performed between September 2023 and December 2024.

Which time metrics differed between the two robotic systems?

Console time showed no significant difference, but operative time tended to be longer with hinotori™. Robot roll-in to console start and posterior mesh fixation times were significantly longer with hinotori™.

What was the overall conclusion regarding perioperative outcomes?

RASC using hinotori™ produced perioperative outcomes comparable to da Vinci®, though some procedural delays occurred during the initial implementation phase.
