Single-Port Robot-Assisted Radical Prostatectomy with the Novel Shurui Single-Port Robotic Surgical System

Purpose: The aim of this study was to explore the safety and efficacy of radical prostatectomy with a novel Shurui single-port (SR-SP) robotic surgical system. Methods: A total of 11 patients with prostate cancer were enrolled in this study. Extraperitoneal radical prostatectomy was performed using the SR-SP robotic surgical system for all patients. Clinicopathologic data, perioperative data, and short-term surgical outcomes were prospectively collected and analyzed. Results: Of the 11 patients, the median age was 65 years (range 52-73), and the median body mass index was 22.6 kg/m² (range 20.2-26.7). The median operative time was 229 minutes (range 194-317), and the median console time was 167 minutes (range 141-265). The median blood loss was 40 mL (range 10-120), and none of the patients required intraoperative transfusion. There was no conversion to open surgery during the operation, and no assistant ports were added. The surgeons reported a good task load rating with a National Aeronautics and Space Administration Task Load Index (NASA-TLX) score of 25.1 ± 3.3 points. The median postoperative hospital stay time was 7 days (range 4-15). There were no severe intraoperative or postoperative complications (Clavien grade ≥3). Postoperative positive surgical margin occurred in 4 (36.4%) patients. No biochemical recurrence occurred within 1 month of surgery. The continence rate was 72.7% (8/11) 1 month after surgery. Conclusions: The new SR-SP robotic surgical system is safe, effective, flexible, and stable for application in radical prostatectomy.
