Neutrophil to lymphocyte ratio incidence in patients withpartial nephrectomy in the last 5 years and therelationship with padua renal nephrometry score

Aim: In this study, patients who underwent partial nephrectomy through the nephron sparing surgery for renal mass in our clinic were retrospectively screened. We aimed to evaluate patients by preoperative neutrophil to lymphocyte ratio insidence and the relation with PADUA scoring system, which is the widely used nephrometry score. Predictors of tumor stage, size, histological grade, PADUA score, preoperative and postoperative hemoglobin, platelet and neutrophil to lymphocyte ratio, bleeding quantities were taken as criteria. Material and Method: 51 patients and 52 renal masses were included into the study. Of these, 5 and 47 were operated with laparoscopic and open surgery respectively. Significance test was performed in terms of preoperative and postoperative neutrophil to lymphocyte ratios, PADUA scores, bleeding quantities, pathological types and histological grades. Results: No statistically significant difference was found in the histological grade, pathologic type, PADUA score, preoperative and postoperative neutrophil to lymphocyte ratios in the statistical comparison of patients with partial nephrectomy. Only age together with tumor size and preoperative neutrophil to lymphocyte ratio together with bleeding amount significantly correlated. Conclusion: Partial nephrectomy is a technique that can be safely performed especially in T1 early stage tumors. However, we think that preoperative neutrophil / lymphocyte ratio can not be used as a prognostic factor in early stage tumors.
