Abstract :Objective: Percutaneous nephrolithotomy insert ignore into journalissuearticles values(PNL); is first-line treatment modality for large and complex stones, however it is associated with potential morbidity and severe complications. Therefore, we aimed to evaluate the success and complication rates according to stone localization in large sample group following PNL. Material and Methods: Total number of 782 patients who underwent PNL, were included in this retrospective multicenter study. Patients were divided into two major groups; simple stones group insert ignore into journalissuearticles values(upper pole, pelvis, lower pole); and complex stones group insert ignore into journalissuearticles values(partial staghorn, multi-caliceal, pelvis+lower pole, complete staghorn);. Surgery time, fluoroscopy time, complications, hospitalization and nephrostomy catheter removal day were recorded. Results: In our study, 525 cases insert ignore into journalissuearticles values(67.1%); had simple stones, 257 insert ignore into journalissuearticles values(32.9%); complex stones. The most frequent insert ignore into journalissuearticles values(34.3%); stone localization was lower pole. Overall blood transfusion rate was 15.1%. Significantly increased in mean number of accesses, surgery time, fluoroscopy time, nephrostomy removal time and hospitalization documented in cases with complex stones insert ignore into journalissuearticles values(p-values = 0.000, 0.000, 0.009, 0.000 and 0.000, respectively);. Overall complication rate was 9.7% insert ignore into journalissuearticles values(n=76); and the most frequent complication insert ignore into journalissuearticles values(4.4%); was severe hemorrhage. Overall stone-free rates insert ignore into journalissuearticles values(SFR); are 74.6% insert ignore into journalissuearticles values(n=583);. Furthermore, complication rate insert ignore into journalissuearticles values(14.4% vs. 7.4%); was statistically higher and SFR insert ignore into journalissuearticles values(57.6% vs. 82.9%); was lower in cases with complex stones than simple stones insert ignore into journalissuearticles values(p-values = 0.002 and 0.000, respectively);. Conclusions: Our findings clearly demonstrated that PNL achieved higher success rate and lower complication risk in patients with simple stones than complex stones. PNL is significantly associated with shorter operation duration and hospitalization in simple stones group. Furthermore, PNL provided relatively higher overall SFR and lower complication rates in our large sample group compared to the published data.
