Understanding the Urine Electrolyte Profile of the Individual Renal Unit

Stopped early

Conditions studied: Kidney Calculi, Nephrolithiasis, Urolithiasis

In brief

The investigators objective is to determine if urinary electrolyte abnormalities exist in only one or both kidneys in participants with and without a history of kidney stones. To meet this objective, the investigators are going to take urine samples from each kidney at the time of kidney stone surgery. The samples will then be analyzed for absolute and relative differences in the concentrations of urine electrolytes, such as calcium.
