Summary
Brief summary (as posted)
A single-blinded, prospective randomized parallel controlled clinical trial is designed and will be conducted from July 2022 to November 2023 (anticipated). One hundred and thirty-six patients (anticipated) with renal cancer or bladder cancer or prostate cancer will be enrolled in this study. Those patients will be enrolled by two hospital centers and the patients will be randomly divided into the Micro Hand S surgical robot group and the da Vinci surgical robot group. Robot-assisted partial nephrectomy, radical cystectomy, and radical prostatectomy will be conducted using the Micro Hand S robot or the da Vinci robot. The success rate of operation, assembly time, operation time, intraoperative hemorrhage, continence rate (if applicable), postoperative pain, comprehensive complication index, resident time and surgeon satisfaction were recorded. The aim of the study is to determine whether the newly developed Chinese Micro Hand S surgical robot results in non-inferiority outcomes in urological surgeries compared with the prevalent da Vinci robot.
