Endourology & Stone Disease(구연) (E-157) 다빈치 SP 시스템을 이용한 단일공 비뇨기 로봇수술: 단일기관 100례 경험 이화여자대학교 의과대학 비뇨의학과교실 김광현, 김명, 이동현, 윤하나 Purpose: To report our experience with 100 cases of single-port urologic surgery using da Vinci SP system at a single institution. Methods: Between December 2018 and July 2020, 100 patients underwent single port urologic surgeries with the da Vinci SP system by three surgeons at a single institution. Clinicopatholgoical data, perioperative outcomes and early postoperative outcomes were analyzed. Results: Mean age was 61 (range 17-93, IQR 56-70) and 77 patients were male. Seventy two patients underwent surgeries for malignant disease (radical prostatectomy (n=45), partial nephrectomy (n=18), radical nephrectomy (n=4), nephroureterectomy (n=4) and radical cystectomy (n=1)). Various urological surgeries for benign disease were performed in 28 patients (Table 1). Three urinary diversion (ileal conduit (n=1), Studer neobladder (n=1), W-configuration neobladder (n=1)) and 9 ileocystoplasties were performed with hybrid method (extracorporeal and intracorporeal) via single port site without additional incision. All cases were performed successfully without conversion to open surgery. There was no intraoperative complication and 1 patient required transfusion on postoperative day 2. Complication of Clavien-dindo grade ≥3 developed in 3 patients and 4 patients were readmitted within 30 days of discharge (Table 2) Conclusion: Various urologic surgeries for malignant and benign disease can be safely performed using da Vinci SP system. keywords : Robotic surgery, Single port, Urologic surgery
