Cancer - Kidney(포스터) International Session I (I-04) Rm. 202 10월 31일(목) 15:00-16:00 RAPN Outcomes in patient with PADUA ≥ 10 : Single Surgeon & Single Center Experience Urology Department, Severance Hospital (Sinchon), Yonsei University Ahmad Almujalhem, Ali Alqahtani, Koon Ho Rha Purpose: To study the RAPN outcomes in patient with PADUA ≥ 10 in our center. Methods: retrospectively reviewed group of patients operated from Jan 2011 till December 2016. A 212 patients underwent RAPN. Inclusion criteria was patients with PADUA ≥ 10 and minimum follow up of 48 months, where we studied 76 patients. We reported a single surgeon in single center experience. All cases done robotically with trans peritoneal approach. We studied functional outcomes (eGFR pre OP, 1 month and 1 year post OP), surgical (WIT, EBL, Operative time, Conversion to Radical Nephrectomy, Intra OP complication) & oncological outcomes (PSM, Recurrence, Overall Survival). Results: Total of 212 patients underwent RAPN, and 76 patients met the our inclusion criteria. Estimated GFR means were 82.06 (pre-operatively), 73.42 (1 month post-op), and 73.45 (1 year post-op). WIT mean was 23.5 minutes, while EBL mean was 534ml. Only 7.9% converted to robotic radical nephrectomy, while none converted to open surgery. PSM was only in 10 patients, while only 1 had recurrence of primary tumor. Overall survival was 97.3% over the study period. Conclusion: RAPN is feasible option for complex renal tumor with PADUA score > 10, but it carries risk of longer ischemia time and higher blood loss, while oncological goals are safely achievable. keywords : kidney, RAPN, PADUA
