Sponsor's own description
The metabolic evaluation is crucial for determining possible underlying diseases causing stone growth and to consider the lifestyle changes or medical prophylaxis needed to prevent or at least reduce stone recurrence. 24-hour urine collection is the main part of the metabolic evaluation. The time point is suggested between 3 weeks and 3 month after stone removal, but so far there are no studies comparing 24-hour urine prior and after stone removal. In this study, investigators would like to analyze parameters in the 24-hour urine prior and after complete stone removal to see whether metabolic status can be evaluated no matter stone free or not.
