Condition: Prostate Cancer · Sponsor: Seong Soo Jeon
This single-center, investigator-initiated prospective clinical study aims to evaluate the impact of the Force Feedback function of the da Vinci 5 (dV5) robotic surgical system on surgical skill acquisition and intraoperative safety during robot-assisted radical prostatectomy (RARP). Although robotic surgery is well established in urology, the absence of tactile sensation remains a major limitation of previous systems. The new dV5 platform incorporates real-time haptic (force) feedback, potentially reducing excessive tissue traction and improving surgical precision. A total of 60 patients with clinically localized prostate cancer will be enrolled at Samsung Medical Center. Two surgeons (one faculty and one trainee) will each perform 30 RARP cases, with Force Feedback ON/OFF randomly assigned for each case. The primary endpoints are (1) mean traction force and (2) total instrument path length during seminal vesicle dissection. Secondary endpoints include surgical performance metrics (time, clutch counts), intraoperative safety, postoperative complications, and patient-reported outcomes (IPSS, IIEF-5, EPIC-CP, ICIQ-UI SF). Data will be analyzed using mixed-effects models accounting for surgeon-level random effects. This study seeks to provide quantitative evidence on how Force Feedback enhances surgical learning efficiency, precision, and patient safety in next-generation robotic prostate surgery.
