Factors affecting long‐term renal functions after partial vs radical nephrectomy for clinical T1 renal masses: A Multicentre Study of the Urooncology Association, Turkey

Purpose To compare the functional outcomes of patients who underwent partial (PN) or radical nephrectomy (RN) for clinical T1 (cT1) renal tumours using the Kidney Cancer Database of the Urooncology Association, Turkey. Methods We retrospectively reviewed 1004 patients who underwent PN and RN for cT1 renal tumours at multiple academic tertiary centres between 2000 and 2018. Patients with preoperative end‐stage chronic kidney disease and/or metastatic disease were excluded. Results There were 452 patients in the PN group and 552 patients in the RN group. The median follow‐ups were 74.9 and 83.7 months in RN and PN cohort. The eGFR was significantly reduced in both groups on postoperative day 1 (PN = 13.7 vs RN = 19.1 mL/min/1.73 m2: P
