Brief summary
This is a prospective case series study. To compare urine sample of recurrent stone-formers and non-stone former by multiomics approach to identify potential markers for stone recurrence.
Detailed description
A total of 100 Chinese patients with history of recurrent urinary stone and no history of urinary stone disease (control) will be recruited for the study. 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of Level of urinary metabolomics by multiomics approach in non-stone former | every year up to 3 year | Patient will be reviewed with urine collection for the level of urinary metabolomics including metabolomics and proteomics by multiomics analysis every year up to 3 years |
| Change of Level of urinary proteomics by multiomics approach in recurrent stone-formers | every year up to 3 year | Patient will be reviewed with urine collection for the level of urinary metabolomics including metabolomics and proteomics by multiomics analysis and there will be radiological imaging annually to check if there is any suspect stone every year up to 3 years |
