Brief Summary

The purpose of this study is to add to the investigators' quest to understanding stone disease, by evaluating the metabolites excretion in urine and its relation to microflora present in the stool.

Outcome Measures

Primary Outcomes (1)

  • Bacterial flora in the intestine of patients with kidney stones compared to non-stone forming individuals

    The objective of this study is to compare the bacterial flora in the intestine of patients with kidney stones compared to non-stone forming individuals. If there are differences between stone forming and non-stone forming individuals in the content of their bacterial flora, these will also be correlated with levels of metabolites found in the urine that are known risk factors of stone disease. Difference in bacterial intestinal flora already exists for patients who are obese compared to non-obese individuals.

Study Population

Subjects in the study group are seen at Vancouver General Hospital for their kidney stone disease. Subjects in the control group do not have history or family history of kidney stones and can join the study if they are eligible, wiling to participate, and can provide their specimens at Vancouver General Hospital.

You may qualify if:

  • Controls
  • Age \> 19.
  • No history of kidney stone disease
  • Study Patient (Stone Patient)
  • Age \> 19
  • Radiological evidence indicating presence of a current renal or ureteric stone

You may not qualify if:

  • Pregnancy
  • Positive Urine Culture
  • Active cancer
  • Recurrent urinary infections
  • Gross hematuria
  • Inability to provide informed consent
  • In the Investigator's opinion, the patient would not be good for the study.
  • Controls Only:
  • Family history of kidney stones
  • History of kidney stones
