Introduction: This study aimed to evaluate the chronologic changes in renal function after laparoscopic partial (LPN) or radical nephrectomy (LRN) in patients with clinical T1 renal cell carcinoma. Methods: In this retrospective study, patients with clinical stage T1 renal cell carcinoma who underwent LPN or LRN were divided into three groups, namely, LPN‐A group including LPN patients with WIT ≤25 minutes, LPN‐B group including LPN patients with WIT >25 minutes, and LRN group. Perioperative complications that occurred within 30 days after surgery were retrieved. All patients were followed‐up every 3 months to evaluate the estimated glomerular filtration rate. The primary endpoint of this study was to assess the chronological changes in renal function after surgery. Results: A total of 153 patients were enrolled in this study. The change in estimated glomerular filtration rate between day 1 and 2 weeks after surgery was significantly lower in the LPN‐B group than in the LPN‐A group (p<0.005). Both LPN‐A and ‐B groups achieved eGFR ≥90% 2 weeks after surgery. In addition, the estimated glomerular filtration rate decline from post‐operative day 1 through 24 months in the LPN‐A group or the LPN‐B group was significantly smaller than that in the LRN group (P < 0.001, P < 0.001, respectively). Conclusion: Our results demonstrate the efficacy and safety of LPN in patients with T1 renal cell carcinoma. Although complication rates were similar in both groups, post‐operative renal function was not different between the LPN‐A and ‐B groups [ABSTRACT FROM AUTHOR]
