High Oxalate Levels in Urine (Enteric Hyperoxaluria)

People withenteric hyperoxaluria, or hyperoxaluria caused by an underlying gastrointestinal condition that leads to absorption of too much oxalate from foods and causes kidney stones are asked to participate in a research study being conducted by Montefiore Medical Center. Examples of such conditions include: Crohn’s disease and other inflammatory bowel diseases; disorders of the pancreas due to cystic fibrosis or pancreatitis; or after gastric bypass surgery or surgery to remove a section of the intestine.

You may be eligible to participate in this study if you:

• Are a male or female at least 18 years of age or older
• Have confirmed high levels of oxalate in your urine, which can form crystals and cause inflammation and/or kidney stones

You may not participate in this study if you:
• Are in acute renal failure
• Are unable or unwilling to discontinue Vitamin C supplementation for the duration of the study
• Have a malignancy or have had treatment for malignancy within the past 12 months
