Brief Summary
Kidney stones continue to affect more and more people in the United States with the most recent estimate being 1 in 9 people will develop a stone in their life. While family history is a known risk factor for stone disease, it remains unclear whether this is related to learned dietary habits or a truly inheritable genetic condition. Known inheritable genetic conditions linked to stone formation are uncommon, and thus, routine genetic testing is not currently recommended by any major urologic organizations. Patients who form calcium phosphate predominant stones, a less common type of stone composition, tend to have alkaline urine pH which suggests that the kidneys are unable to rid the body of acid. Management of such patients for stone prevention can be difficult. The Iowa Institute for Human Genomics is one of only a handful of commercial labs which offers genetic testing for stone disease. The aim of this study is to assess the rate of genetic abnormalities amongst calcium phosphate predominant stone formers with alkaline urine. To this end, the investigators plan to enroll calcium phosphate predominant stone forming patients with alkaline urine on 24 hour urine collection who obtain their health care at UIHC to undergo free genetic testing via blood draw to assess for genetic abnormalities. The investigators will also collect information already available in the subject's chart to assess for other patterns between blood and urine tests and any genetic variants.
