Official title
Risk Factors and Development of a Predictive Model for Stone-Associated Inflammatory Ureteral Polyps: A Retrospective Cohort Study With Prospective Validation
Overview
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.
Detailed description
This is a bicentric bidirectional cohort study; retrospective cohort (n=629) has been fully enrolled, prospective cohort is ongoing consecutive enrollment.
Primary outcome measures
- Number of Participants with Intraoperatively Confirmed Inflammatory Ureteral Polyps [Time frame: At the time of ureteroscopic surgery]
Eligibility criteria
Inclusion criteria
