  "abstract": "Purpose\n\nThis study evaluated the associations of post-ESWL hydration habits with single-session ESWL success and 7-day stone-free status and examined whether these associations varied according to stone size.Methods\n\nThis single-center retrospective cohort study included 570 patients who underwent ESWL for ureteral stones at the Second Affiliated Hospital of Fujian Medical University between June 2024 and December 2025. Hydration habits were classified as early concentrated hydration (≥2 L within the first 8 hours after waking) or distributed daily hydration (total daily fluid intake ≥2 L but <2 L within the first 8 hours after waking). Primary outcomes were single-session ESWL success and 7-day stone-free status. Multivariable logistic regression was used to evaluate associations between hydration habits, stone size, their interaction, and study outcomes.Results\n\nBaseline characteristics were comparable between groups. Stone size was inversely associated with single-session ESWL success and 7-day stone-free status. Significant interactions were observed between hydration habits and stone size for single-session ESWL success (interaction OR=1.42, 95% CI: 1.09-1.84) and 7-day stone-free status (interaction OR=1.99, 95% CI: 1.41-2.81). Model-based probability curves crossed at approximately 6.82 and 7.30 mm, respectively; these values represent model-derived crossing points rather than validated clinical thresholds. In a post hoc exploratory analysis of patients with stones ≥7 mm, early concentrated hydration was associated with higher odds of single-session ESWL success (OR=1.90, 95% CI: 1.12 ~ 3.20) and 7-day stone-free status (OR=2.26, 95% CI: 1.36 ~ 3.75).Conclusion\n\nEarly concentrated hydration was associated with more favorable ESWL outcomes, particularly among patients with larger stones.",
