While percutaneous nephrolithotomy (PCNL) and ureteroscopy (URS) are both effective treatment options, the safety of PCNL has been well-established in CKD patients, whereas the safety profile of URS remains less clear.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective cohort study using the TriNetX database was conducted to compare outcomes in CKD patients undergoing URS or PCNL. Patients aged \u226518\u202fyears with a diagnosis of renal stones and CKD were included, excluding those on dialysis. Propensity score matching (PSM) was performed to balance baseline characteristics. The primary outcome was the 5-year rate of major adverse kidney events (MAKE), a composite of mortality, dialysis initiation, and worsened renal function. Secondary outcomes included all-cause mortality and dialysis dependence. Subgroup and sensitivity analyses were performed to ensure robustness.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 5,470 eligible patients, 837 underwent URS and 4,633 underwent PCNL, with 723 patients matched in each group post-PSM. There was no significant difference in MAKE between URS and PCNL (HR 0.93; 95% CI 0.68\u20131.28; <jats:italic>p<\/jats:italic>\u202f=\u202f0.6952).

However, the lack of information regarding stone size, anatomical location, and procedure-specific details (e.g., device use or surgical technique) is a major limitation of our
