Comparison of Robot-Assisted Laparoscopic Prostatectomy Using the Made-in-Japan Robotic System Hinotori Versus Da Vinci: A Propensity Score-Matched Analysis.

BACKGROUND

We compared the surgical outcomes of patients who underwent robot-assisted radical prostatectomy (RARP) using hinotori with those of patients who underwent RARP using da Vinci Xi through propensity score matching to evaluate the potential benefits and efficacy of hinotori.

METHODS

Perioperative data of patients who underwent RARP between 2017 and 2023 were retrospectively evaluated.

RESULTS

After adjusting for preoperative risk factors, each group comprised 118 propensity score-matched patients. Both median total operative time and median console time were significantly longer in the hinotori group (median differences, 26 and 23 min, respectively). Although the hinotori group had lower estimated blood loss, no significant differences were noted between the groups in postoperative complications, positive surgical margin rates, 12-month biochemical recurrence rates, and urinary continence recovery rates.

CONCLUSIONS

Although RARP requires more time with hinotori, our study demonstrated that RARP can be performed safely and effectively immediately after the installation of hinotori.
