They only make up 15% of all kidney stones, but account for a much higher percentage of mortality (up to 67%) compared to other stonesdue to the infectious component. Treatment is to ensure ...


Night Time Use of Thiazide Diuretics for Improved Reduction in Stone Risk in Stone Formers With Elevated Urine Calcium

The study will be divided into three phases for every single patient, investigators will study 15-20 stone formers who have previously documented elevated urine calcium excretion, with a plan to measure their urine chemistries at baseline (if they currently use thiazide diuretics, they will come off of their respective thiazide ...
