THE KangDuo Surgical Robot-1500 (KD-SR-1500) has demonstrated high feasibility and efficiency in robot-assisted radical prostatectomy (RARP) for patients with prostate cancer, according to a recent clinical study. This newly developed surgical robot shows promise in improving surgical outcomes and reducing complications, marking a significant advancement in robotic-assisted surgery.
The study was a prospective, multicentre, single-arm trial involving patients aged 18-75 with suspected T1-2N0M0 prostate cancer scheduled for RARP. Perioperative and follow-up data were recorded, with outcomes assessed through surgical margin status, prostate-specific antigen (PSA) levels at six weeks post-surgery, and urinary continence rates. Ergonomics were evaluated using the NASA Task Load Index (NASA-TLX), and complications were classified using the Clavien-Dindo system. Of the 31 patients enrolled, one withdrew due to severe abdominal adhesions. The remaining 30 procedures were completed successfully without conversions or secondary surgeries. Median docking and console times were 3.8 minutes and 104.6 minutes, respectively, with a median blood loss of 50 mL. Positive surgical margins were observed in 20% of cases, while PSA persistence was noted in 3.4% of patients. The urinary continence rate at four weeks post-catheter removal was 75.9%. No major complications or equipment-related adverse events were reported, and the mean NASA-TLX score was 23.9, indicating favourable ergonomics.
These findings suggest that the KD-SR-1500 is a feasible and effective tool for managing T1-T2 prostate cancer. Its precision, low complication rates, and ergonomic design make it a valuable addition to clinical practice. Future studies should explore its long-term oncologic outcomes and cost-effectiveness, as well as its potential application in other surgical procedures. The integration of such advanced robotic systems could revolutionise surgical care, offering patients with prostate cancer safer and more efficient treatment options.
