Cancer - Bladder, Pelvis, Ureter & Others(구연) (E-052) 단일 신장 환자들에 있어 근치적 방광 적출술 시행 시 회장 도관 요루 형성술과 요관 피부 문합술 간 수술 후 결과 비교. 성균관대학교 의과대학 비뇨기과학교실 유현수, 강민용, 성현환, 전황균, 서성일, 전성수, 이현무, 정병창 Objectives We evaluated peri-operative and functional outcomes for ileal conduit (IC) versus ureterocutaneostomy (UC) for single kidney patients who underwent radical cystectomy (RC). Materials and Methods We identified single kidney patients with bladder cancer treated with RC and urinary diversion between 2004 and 2020. Patients were performed radical nephroureterectomy (RNU) with RC or before RC. A total of 43 patients were included. After patients were stratified by 2 category according to point of RNU, perioperative outcomes including operative time, EBL, transfusion rate, hospital days, complication rate and renal functional outcomes were compared between IC and UC group. Results Among 43 patients, 23 patients were performed RNU before RC (previous RNU) and 20 patients were performed RNU with RC (concurrent RNU). Among 23 patients with previous RNU, greater deterioration of renal function was shown in IC group, but not significantly (p=0.332). And regarding op time, EBL, transfusion rate, hospital days and complication rate, there were no significant difference between groups (p=0.599, p=0.631, p=0.637, p=0.205 and p=0.552, respectively). Among 20 patients with concurrent RNU, greater deterioration of renal function was shown in UC group, but not significantly (p=0.605). Also, regarding op time, EBL, transfusion rate, hospital days and complication rate, there were no significant difference between IC and UC groups. Conclusion UC is not significantly inferior to IC according to renal functional outcome and perioperative outcome including complication rate and transfusion rate. UC could be recommended as a good choice in single kidney patients who underwent RC and urinary diversion. keywords : single kidney, ileal conduit, ureterocutaneostomy
