Safety and Efficacy of Flexible Ureterorenoscopy Surgery in Different Age Groups

Abstract

Objective: To comparatively investigate the efficacy, safety and complications of flexible ureterorenoscopy (f-URS) in the treat-ment of patients of different age groups ( 60, 60-74 and 60 years (Group 1), 60-74 years (Group 2) and _75 year (Group 3). The patients' American Society of Anesthesiologists (ASA) score, Charlson Comorbidity Index (CCI), anticoagulant use, stone-free rates and surgical and medical complication rates were examined for each group. Results: There were 688 patients in Group 1, 230 in Group 2, and 38 in Group 3. A significant difference was observed between the age groups in terms of CCI and anticoagulant use (p<0.001 for both). The highest rate of medical complications was observed in Group 3 at 42.1%, followed by Group 2 at 17.8%, while the lowest rate was observed in Group 1 at 2.3% (p<0.001). As a result of the multivariate analysis, receiving anticoagulant treatment (p=0.002) and having a high CCI (p=0.005) were independent predictors of medical complication development. Conclusion: It was clearly demonstrated that f-URS could be used as a safe and effective alternative for the treatment moderate-size kidney stones in all age groups.
