To compare the outcomes in patients who have been treated with flexible ureterorenoscopy (f-URS) and percutaneous nephrolithotomy (PNL) in managing stone-bearing caliceal diverticula. Between April 2007 and October 2013, we performed a retrospective analysis of 54 evaluable patients (28 women and 26 men) with symptomatic stone-bearing caliceal diverticula, who underwent PNL (n?=?29) or F-URS (n?=?25) in four referral hospitals in Turkey. The groups were compared with respect to demographics, stone location/size, success rate, stone-free status, symptom-free status, complication rates, and hospital stay. The average stone burden preoperatively was significantly larger in patients who were treated with PNL, with the average size for f-URS being 154?±?77?mm2 and that for PNL being 211?±?97?mm2 (p?=?0.023). Symptom-free rates, success rates, stone-free rates and clinically insignificant residual fragments were similar between the groups (p?=?0.880 vs. p?=?0.537 vs. p?=?0.539, and p?=?0.877, respectively). There was no statistical difference between the groups for minor complications (p?=?0.521) but no major complication (Clavien III–V) occured in the f-URS group; although there were three major complications (10.3?%) (Clavien III) in the PNL group (p?Hospitalization time per patient was 1.04?±?0.20?days in the f-URS group, while it was 3.86?±?1.94?days in the PNL group (p?
