Dhayat NA, et al. – Experts conducted this study to assess the effects of furosemide/fludrocortisone test and clinical parameters to diagnose incomplete distal renal tubular acidosis in kidney stone formers. This study suggested the effectiveness of the furosemide/fludrocortisone test for incomplete distal renal tubular acidosis screening in stone formers. However, confirmation was needed for an abnormal furosemide/fludrocortisone test result by ammonium chloride testing. By use of nonprovocative clinical parameters, incomplete distal renal tubular acidosis could reliably be excluded in stone formers
