Summary

The goal of this observational study is to investigate the systemic pathogenesis and identify potential diagnostic biomarkers in patients with ureteral stricture and healthy volunteers. The main questions it aims to answer are:

What are the systemic differences in the gut microbiome, urine microbiome, and metabolomic profiles (fecal, urinary, and serum) between patients with ureteral stricture and healthy controls? What are the correlations between these microbial/metabolic alterations and clinical phenotypes, such as stricture severity, inflammatory levels, and renal function? Researchers will compare the biological panoramic profiles of patients with ureteral stricture to those of healthy controls to see if specific "microbiome-metabolite-disease" regulatory networks drive the development of the condition.

Participants will:

Provide stool samples for gut microbiome (16S/Metagenomics) and metabolomic analysis.

Provide urine samples for urine microbiome and metabolomic analysis. Provide blood (serum) samples for systemic metabolomic profiling. Undergo clinical assessments, including medical history collection, imaging (e.g., CT/IVP), and laboratory tests (e.g., renal function, inflammatory markers) to evaluate disease severity.
