    To compare the outcomes of flexible ureterorenoscopy (F-URS) with extracorporeal shock wave lithotripsy (ESWL) for the treatment of upper or mid calyx kidney stones of 10 to 20 mm. A total of 174 patients with radioopaque solitary upper or mid calyx stones who underwent ESWL or F-URS with holmium: YAG laser were enrolled in this study. Each group treated with ESWL and F-URS for upper or mid calyx kidney stones were retrospectively compared in terms of retreatment and stone free rates, and complications. 87\% (n = 94) of patients who underwent ESWL therapy was stone free at the end of 3rd month. This rate was 92\% (n = 61) for patients of F-URS group (p = 0.270 p > 0.05). Retreatment was required in 12.9\% of patients (n = 14) who underwent ESWL and these patients were referred to F-URS procedure after 3rd month radiologic investigations. The retreatment rate of cases who were operated with F-URS was 7.5\% (n = 5) (p = 0.270 p > 0.05). Ureteral perforation (Clavien grade 3B) was occured in 3 patients (4.5\%) who underwent F-URS. Fever (Clavien grade 1) was noted in 7 and 5 patients from ESWL and F-URS group, respectively (6.4\% vs 7.5\%) (p = 0.78 p > 0.05). F-URS and ESWL have similar outcomes for the treatment of upper or mid calyx renal stones of 10-20 mm. ESWL has the superiority of minimal invasiveness and avoiding of general anethesia. F-URS should be kept as the second teratment alternative for patients with upper or mid caliceal stones of 10-20 mm and reserved for cases with failure in ESWL.
