Primary Outcome Measures
NameTimeMethod
Occurrence of hypercalciuria beyond the lithogenic threshold for age. This will be assessed by measuring the calcium/creatinine ratio in mmol/mmol in the first morning urine sample collected during at least one of the three measurements taken on day 7, day 14, and day 28.

Secondary Outcome Measures
