Abstract
Purpose: The aim of this study was to assess the effect of pre-operative blood glucose (POBG) levels on the length of stay (LOS) in patients with renal cell carcinoma (RCC) undergoing laparoscopic nephrectomy.Methods: We collected clinical data on 338 patients with RCC who underwent laparoscopic nephrectomy between 2014 and 2019. Univariate and multivariate logistic regression and dose-response analysis curves of restricted cubic spline function were used to investigate the relationship between POBG and LOS.Results: According to the level of POBG, we divided the patients into three groups: <4.94 mmol/L group, 4.94 to <7.11 mmol/L group, and ≥7.11 mmol/L group. According to the dose-response analysis curves, we found that the adjusted risk of LOS > 2 weeks and LOS > 3 weeks gradually increased with increasing POBG. In addition, we found that among all patients, patients with POBG levels ≥ 7.11 mmol/L had a 115% higher risk of LOS > 2 weeks than patients with POBG levels <4.94 mmol/L [adjusted odds risk (aOR) 2.15; 95% CI 1.11-4.20; p = 0.024] and patients with POBG levels ≥ 7.11 mmol/L had a 129% higher risk of LOS > 3 weeks than patients with POBG levels <4.94 mmol/L (aOR 2.29; 95% CI 1.16-4.52; p = 0.017). Moreover, similar results were observed in the most subgroups analysis.Conclusion: We found that in patients with RCC undergoing laparoscopic nephrectomy, higher POBG levels were significantly associated with prolonged LOS.

Summary
Renal cell carcinoma (RCC) is a common malignancy of the urinary system originating from the kidney, accounting for 8085% of renal malignancies, and its incidence has been increasing in recent years [1]. The reasons for the increase in the incidence of RCC on the one hand is the progress of imaging examination, on the other hand, it the increased exposure to risk factors in the population. Both epidemiological and basic studies suggest that metabolic factors such as obesity, hypertension, diabetes, and dyslipidemia may affect the occurrence and development of RCC [5,6,7]. Studies have found that elevated fasting blood glucose and diabetes are risk factors for cancer development and death in multiple organs, including the kidney [8, 9]
