  Purpose

Test the hypothesis that the new bariatric surgical procedures (BSP) increase stone risk, and will result in an increased incidence and prevalence of stone disease; the purpose is to determine if BSP patients require special management for stone prevention. This study does not include the bariatric surgery but enrolls subjects who are already scheduled for surgery with an affiliated surgeon. The study procedure is to collect 24 hour urines pre-and post surgically to evaluate the risk of kidney stone procedure after surgery.
