The purpose of the Stone Centre Serum and Urine Bank is to provide researchers with large numbers of serum and urine samples from kidney stone patients and controls for study of stone disease detection and treatment, and will take into account different genetic backgrounds, ages, and other patient factors to provide a broad sample size for the study of stone disease The Serum and Urine Bank will undoubtedly be an invaluable tool in the quest to understanding urinary stone disease.
The objective of this research is to identify protein species or other compounds responsible for or contributing to kidney stone initiation and propagation.

|Estimated Enrollment :||500 participants|
|Observational Model:||Case Control|

The control subjects of this study will be asked to undergo renal ultrasound examination, if available, or will be asked to complete a disease history form to determine the presence or lack of a kidney stone. Urine and serum will then be taken for storage until further analysis.
Controls will be asked to undergo a screening renal ultrasound to ensure they are stone free, this will take approximately 45 minutes. If the controls are asked to complete the history form, this will not take more than 20 minutes. They will also give a blood and urine sample during this time to bring the total extra time up to at most 60 minutes for controls."
The stone group will undergo standard diagnostic procedures for their condition and recovery process. Serum and urine for storage and analysis will be taken prior to stone treatment and 6 weeks following stone treatment. This will allow for the determination of differences in a stone patient's protein profile while they have their stone and after they are stone free. All patients will be required to have a stone patient metabolic evaluation which includes serum and urine testing. The analysis will focus on the serum and urine sample that they provide.
The stone patient will be asked to undergo one extra tube of blood during their preoperative assessment which should only add a few seconds to their visit.
- genetic factors in stone disease [ Time Frame: one time sample ]
Biospecimen Retention: Samples With DNA
Urine and serum of stone-forming individuals and non-stone forming controls will be banked for analysis of protein biomarkers and predisposing factors. Ureteral stents removed from patients that would otherwise be discarded will be processed and stored to assess for bacterial and biofilm adherence.
Serum and Urine specimens will be collected, de-identified, and banked/retained.
