Analysis of survival for patients with chronic kidney disease primarily related to renal cancer surgery

Objectives To evaluate predictors of long‐term survival for patients with chronic kidney disease primarily due to surgery (CKD‐S). Patients with CKD‐S have generally good survival that approximates patients who do not have CKD even after renal cancer surgery (RCS), yet there may be heterogeneity within this cohort. Patients and Methods From 1997 to 2008, 4 246 patients underwent RCS at our centre. The median (interquartile range [IQR]) follow‐up was 9.4 (7.3–11.0) years. New baseline glomerular filtration rate (GFR) was defined as highest GFR between nadir and 6 weeks after RCS. We retrospectively evaluated three cohorts: no‐CKD (new baseline GFR of ≥60 mL/min/1.73 m2); CKD‐S (new baseline GFR of
