Kidney stone formers
Consuming a special drink (potassium citrate) during an all-day visit to the University of Chicago research clinic Subjects in both groups will be asked to partake in the same activities, as follows: The day before presenting to the research clinic, subjects will collect urine at home. Subjects will then come to the research clinic at the University of Chicago in Hyde Park, where they will spend most of the day. We will give them a special liquid that contains potassium citrate. After this, we will collect urine and blood samples throughout the day. While at the clinic, subjects will also receive a boxed lunch at the end of the visit.
