Effect of Diet Orange Soda on Urinary Lithogenicity
September 6, 2012 updated by: David S. Goldfarb, M.D., VA New York Harbor Healthcare System
Beverages containing citrate may be useful in increasing urine citrate content and urine pH.
Such changes in urine chemistry could help prevent kidney stones.
Diet orange soda has more citrate than other similar beverages.
The investigators are interested in whether diet soda will improve urine chemistry in the appropriate manner.
