Official Title: Comparison of Furosemide/Fludrocortisone With Ammonium Chloride Loading Test in the Diagnosis of Incomplete dRTA in Kidney Stone Formers

Brief Summary:

Purpose

1. To compare the performance of the two currently employed urinary acidifications tests in stone formers, the furosemide/fludrocortisone and ammonium chloride loading test.
2. To study the impact of polymorphisms in the genes ATP6V1B1, ATP6V0A4 and SLC4A1 on urinary acidification in stone formers.
