Evaluation of the New Robotic Platform "HINOTORI™" in Urologic Robot-Assisted Surgery: From a Comparison with da Vinci Surgical System in Sacrocolpopexy.

HINOTORI™ is a robotic-assisted surgical platform developed in Japan. It has been applied in urologic procedures such as robot-assisted radical prostatectomy (RARP) and partial nephrectomy (RAPN). This study aimed to evaluate the clinical performance of HINOTORI™ compared with the da Vinci surgical system by analyzing outcomes of robot-assisted sacrocolpopexy (RSC) performed by a single skilled surgeon using a uniform surgical procedure. A total of 125 patients who underwent RSC for pelvic organ prolapse (POP) were analyzed. Surgical outcomes were compared between the HINOTORI™ (h-RSC group) and da Vinci (d-RSC group) platforms. Evaluated parameters included operative time, robotic console time, anterior compartment dissection time, suture time per stitch, perioperative complications, hospital stay, and POP recurrence. Operative and robotic console times were significantly longer in the h-RSC group (148 vs. 139 min, < 0.005; 109 vs. 95 min, < 0.001). Anterior compartment dissection time showed no significant difference ( = 0.58), but suture time per stitch was longer in the h-RSC group (76 vs. 60 s, < 0.005), possibly due to limited suture-cutting functionality, requiring manual assistance. No significant differences were observed in perioperative complications, hospital stay, and POP recurrence. HINOTORI™ demonstrated surgical precision and safety comparable to the da Vinci surgical system. It may serve as a viable alternative robotic platform, supporting broader adoption of robot-assisted surgical technologies.
