Furosemide/Fludrocortisone Test and Clinical Parameters to Diagnose Incomplete Distal Renal Tubular Acidosis in Kidney Stone Formers.

The data indicate that incomplete distal renal tubular acidosis can reliably be excluded in stone formers by use of nonprovocative clinical parameters, and the furosemide/fludrocortisone test can be used for incompletedistal renal Tubular Acidosis screening inStone formers, but an abnormal furosemia chloride test result needs confirmation by ammonium chloride testing.
