Introduction: Chronic kidney disease (CKD) is a major health issue worldwide, which leads to end-stage renal failure and cardiovascular events. Neutrophil to lymphocyte ratio (NLR) is a surrogate marker of inflammation and has been widely studied in malignancies, hypertension, heart diseases, and vascular diseases. In this study, we aimed to investigate if NLR represents renal reserve and function after partial or radical nephrectomy.Methods: We conducted a retrospective study consists of patients who had undergone radical/partial nephrectomy in our hospital and/or who admitted to urology and nephrology clinics as an outpatient. Patients were divided into four groups: Group 1 (n=46): Healthy controls; Group 2 (n=50): Patients who had undergone unilateral partial nephrectomy; Group 3 (n=46): Patients who had gone unilateral nephrectomy; Group 4 (n=82): Patients who had CKD.Results: The mean NLR of each group was as follows: Group 1: 2.140.73; Group 2: 3.52 +/- 3.74; Group 3: 3.64 +/- 3.52, and Group 4: 3.53 +/- 2.30. NLR was lower in Group 1 compared to other groups but statistically significant difference was observed only between Group 1 (control) and Group 4 (CKD), 2.14 +/- 0.73 versus 3.53 +/- 2.30 (p=.005). In non-parametric correlation analysis NLR was found negatively correlated with GFR and positively correlated CKD stage (p=.028 for both correlations).Conclusions: The NLR may constitute a practical predictor of CKD besides Cr in patients who had undergone partial or radical nephrectomy.
