Background/Aim: Surgeon experience, which is an important factor in reducing surgical complications, has been underestimated when analysing percutaneous nephrolithotomy (PNL) outcomes. Aim of this study was to investigate the impact of annual case volume (ACV) of endourologists and urologists on PNL outcomes including stone-free status (SFS) and complications. Methods: A total of 530 patients who underwent PNL in the Clinic between January 2018 and January 2023 were retrospectively analysed. The patients were divided into two groups: those operated by endourologists (Group 1, n = 324) and by urologists (Group 2, n = 206). The two groups were statistically compared in terms of postoperative SFS and complications. Results: There were two endourologists in Group 1 and four urologists in Group 2. The mean ACV was 73.56 ± 7.43 in Group 1 and 23.81 ± 9.09 in Group 2, indicating a statistically significantly higher rate in Group 1 (p 24 for ACV and CROES scores were the significant predictors of SFS (p = 0.004 and p 24 (p 24 increases SFS rate by 2.13 with lower complication rates in patients undergoing PNL. Further multi-centre, large-scale studies are required to investigate the effect of surgical experience and ACV on postoperative outcomes and to predict PNL outcomes with high accuracy.
