Brief Summary
This is a single-center, observational study including a retrospective cohort and a prospective validation cohort. The study aims to identify independent risk factors for inflammatory ureteral polyps in patients with ureteral calculi and develop a preoperative predictive model. The retrospective part will analyze clinical and imaging data of patients treated at the First Hospital of Jilin University between 2018 and 2025. The prospective part is currently recruiting participants to validate the model. The primary outcome is the intraoperative diagnosis of inflammatory ureteral polyps.
