摘      要：Background:The KangDuo-Surgical Robot-01(KD-SR-01)system is a new surgical robot recently developed in China.The aim of this study was to present our single-center experience and mid-term outcomes of urological procedures using the KD-SR-01 system.Methods:From August 2020 to April 2023,consecutive urologic procedures were performed at Peking University First Hospital using the KD-SR-01 system.The clinical features,perioperative data,and follow-up outcomes were prospectively collected and analyzed.Results:A total of 110 consecutive patients were recruited.Among these patients,28 underwent partial nephrectomy(PN),41 underwent urinary tract reconstruction(26 underwent pyeloplasty,3 underwent ureteral reconstruction and 12 underwent ureterovesical reimplantation[UR]),and 41 underwent radical prostatectomy(RP).The median operative time for PN was 112.5 min,157.0 min for pyeloplasty,151.0 min for ureteral reconstruction,142.5 min for UR,and 138.0 min for RP.The median intraoperative blood loss was 10 mL for PN,10 mL for pyeloplasty,30 mL for ureteral reconstruction,20 mL for UR,and 50 mL for RP.All procedures were successfully completed without conversion,and there were no major complications in any patient.The median warm ischemia time of PN was 17.3 min,and positive surgical margin was not noted in any patient.The overall positive surgical margin rate of RP was 39%(16/41),and no biochemical recurrence was observed in any RP patient during the median follow-up of 11.0 months.The surgical success rates of pyeloplasty and UR were 96%(25/26)and 92%(11/12)during the median follow-up of 29.5 months and 11.5 months,respectively.Conclusion:The KD-SR-01 system appears feasible,safe,and effective for most urological procedures,based on our single-center experience.
