Chronic kidney disease following nephrectomy for renal tumours: retrospective analysis risk factors

Abstract

Objective: We aimed to determine factors responsible for chronic kidney disease (CKD) following nephrectomy for renal tumours. Methods: A retrospective study was undertaken in patients underwent partial or radical nephrectomy due to kidney tumour between January 2015 and June 2020. Patients with eGFR above 60 ml/min/1.73m2 were included in the study. Demographic information, surgical features, eGFR values and some comorbidities of patients were recorded. The patients were evaluated for the development of CKD according to the CKD-EPI equation postoperatively. Results: One hundred and sixty-six patients who underwent radical (n = 125) or partial (n = 41) nephrectomy were included to study. According to the logistic regression analysis, radical nephrectomy (adjusted OR 0.139 (95% CI 0.038–0.507), p = 0.003), age (adjusted OR 1.037 (95% CI 1.001–1.074), p = 0.045), preoperative proteinuria (adjusted OR 0.251 (95% CI 0.084–0.750) p = 0.013) and preoperative lower eGFR (adjusted OR 0.943 (95% CI 0.917–0.969) p < 0.001) were determined as independent predictor for development of CKD. Conclusions: CKD is an important disease that causes morbidity and mortality. Age, type of surgery and preoperative eGFR and preoperative proteinuria are an independent risk factor for CKD development. Patients should be informed about this problem before surgery.
