Objective: To evaluate the proportion of US Medicare patients undergoing ureteroscopy (URS) for kidney stone management at risk for adverse outcomes and analyze the association between risk factors and adverse events.
Methods: Data from Medicare patients aged ≥65 who underwent URS between 2019 and 2023 were analyzed. Nine risk factors were examined for their prevalence and association with sepsis and intensive care unit (ICU) admission within 30 days, extended length of stay (LOS) during the index procedure, and death within 90 days.
