Abstract Aims To evaluate whether initiating sodium‐glucose cotransporter 2 inhibitors (SGLT2i) within 3 months after a urinary tract infection (UTI) is associated with improved long‐term outcomes in patients with type 2 diabetes mellitus (T2DM), compared with dipeptidyl peptidase‐4 inhibitors (DPP‐4i). Materials and Methods A retrospective cohort study was conducted using the TriNetX US Collaborative Network (2016–2023). Adults with T2DM who initiated SGLT2i or DPP‐4i within 90 days after a UTI or pyelonephritis diagnosis were identified. Propensity score matching (1:1) was applied to balance baseline covariates. The primary outcome was mortality. Secondary outcomes included major adverse kidney events (MAKE), major adverse cardiovascular events (MACE), hospitalisation, dialysis dependence, emergency department (ED) visits, and sepsis. Outcomes were assessed over a 4‐year period using Cox proportional hazards models and Kaplan–Meier analysis. Results After matching, 2129 patients were included in each group. Compared with DPP‐4i, SGLT2i use was associated with lower risks of mortality (HR 0.59, 95% CI 0.45–0.77), MAKE (HR 0.78), hospitalisation (HR 0.89), dialysis dependence (HR 0.43), sepsis (HR 0.75), and ED visits (HR 0.88). No significant difference was found for MACE (HR 0.91, 95% CI 0.79–1.04). Conclusions In patients with T2DM recovering from UTI, the use of SGLT2 inhibitors was associated with lower risks of mortality, kidney complications, and infection‐related outcomes compared with DPP‐4 inhibitors. These findings support the safety and clinical benefit of continuing or initiating SGLT2i during the post‐infectious phase, even after a recent urinary tract infection.
