Conclusion
RIRS is an effective and safe surgical method in the treatment of renal
stones. In our study, the presence of abnormal kidney anatomy, multiple
stones, operative time, and residual stones were determined as
independent predictive factors for complication development after RIRS
whereas the presence of residual stones was the only independent
predictive factor for major complications. MCCS and SCS are fast and
easily applicable classification systems for grading RIRS-related
complications.
