Evaluation of Multiple Alkalinizing Agents on Urinary Stone Risk Parameters in Stone and Non-stone Formers on a Metabolically Controlled Diet
University of Texas Southwestern Medical Center
Summary
The purpose of this study is to compare over the counter and alternative prescription urinary alkalinizing agents to slow release potassium citrate in their ability to modify urinary parameters associated with stone formation.
Description
Kidney stones are a common medical problem, occurring in almost 10% of people in the United States1. Furthermore, 50% of patients will recur within 10 years2. Metabolic testing is advised in recurrent stone formers, as well as those considered high risk, to assess for a specific abnormality which may prompt intervention to prevent future stone formation. Non-surgical interventions include both dietary counselling, as well as pharmacotherapy. One of the most commonly prescribed class of pharmacotherapies is alkali therapy which can be used to both increase the urinary pH and raise the urine ci…
