953 Outcomes of Partial Nephrectomy for pT3a Renal Cell Cancer Over 20 Years at a Single Centre

Abstract Aim There is limited information on outcomes of pT3a RCC treated with PN. Retrospective studies cT1/2 upstaged to RN vs PN show contradictory results. Method analysis all renal tumours removed by either or between 2000-2020 at a single centre performed 6 surgeons median follow up period 4 years. Results 186 cases were and 78 was CT suspicion T3a disease in 1 cases. The mean tumour size 4.5cm vs. 8cm. Preoperative postoperative eGFR similar groups smaller drop from preop post op the group (16 20ml/min) number patients who went have replacement therapy for end stage failure 2 group. At years up, 86% patient alive 93% had RN. Of died 5.6% due cancer 8.6% rate any recurrence spread detected 21% 38% Conclusions This case series suggests reasonable option strong indications nephron sparing surgery.
