Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Urine will be saved for multiomics analysis, including metabolomics, proteomics, etc. Thereafter, integrated multiomics calculation of recurrent stone can be studied for the differentiation of recurrent stone former and non-stone former.
After completing the preliminary and screening experiments, a large validation cohort (1000 Chinese patients with history of recurrent urinary stone) will be carried out. The patients will then be follow-up in clinic for at least 3 years, with minimum annual review and imaging to detect for any stone recurrence, as defined as increase in stone size and number, or symptomatic stone events. Targeted biomarkers measurement, based on part 1 result, will be done and the result will be used to correlated with the clinical outcomes of stone recurrence.
