Abstract
The authors retrospectively evaluated 6319 patients with renal tumors from 1980 to 2018 of whom 56% were treated with radical nephrectomy (RN) and 44% with partial nephrectomy (PN). They utilized multivariable linear and competing risk Cox proportional hazards models for increase in chronic kidney disease (CKD) staging to determine if there was a significant interaction between type of operation and preoperative CKD stage. They reported 12 months eGFR calculations in 3046 (48%) of the patients. Of note, 2055 patients (33%) had significant preexisting CKD (eGFR<60), 3466 patients (54%) had hypertension, 843 patients (13%) were diabetic, and 3440 patients (54%) were former or current smokers.
