We aimed to analyze the efficacy of flexible ureterorenoscopy (f-URS) and miniaturized percutaneous nephrolithotomy (mPNL) in the management of 10–30 mm renal stones in patients aged >60 years. In prospective non-randomized series, the data of patients who underwent f-URS or mPNL for kidney stones between July 2013 and July 2016 were analyzed. Patients aged >60 years who had renal stones between 10–30 mm were enrolled in the study. The procedure was accepted as successful if the patient was achieved complete stone clearance according to CT imaging between 1–3 months postoperatively. Complications were classified according to the Clavien classification system. In total, 60 patients and 58 patients were underwent f-URS and mPNL, respectively. The mean operation time, fluoroscopy screening time and hospitalization time were significantly shorter for the f-URS (p < 0.001, p < 0.001, p < 0.001, respectively). According to Clavien classification system, complication rates were not significantly different between the groups (p = 0.673). The stone-free rate was 81.7% for the f-URS group and 77.6% for the mPNL gro...
