Kidney stones may be increasing among both men and women in the US, a new study says. The study, published Monday in the journal Mayo Clinic Proceedings, looks at the prevalence of kidney stones over a period of almost three decades -- from 1984 to 2012 -- among more than 10,000 residents of Minnesota. Young women ages 18 to 39 had the highest increase in cases, jumping from 62 to 252 cases (per 100,000 person-years) from 1984 to 2012. One person-year is a year lived by each participant for the duration of the study… "What we're seeing is an interesting combination of things; certainly, they've gone up quite a bit both in men and women," said Dr. John Lieske, a professor of medicine at the Mayo Clinic in Rochester, Minnesota, and one of the authors of the study.

Context: Kidney stones are a painful health condition, often requiring multiple procedures at great discomfort to the patient. Growing evidence suggests that the incidence of kidney stones is increasing steadily, especially in women. Using data from the Rochester Epidemiology Project, Mayo Clinic researchers investigated the rise in stone formers to determine if this is a new trend, or simply an improvement in the way kidney stones are detected. Their findings appear in the March issue of Mayo Clinic Proceedings. “Symptomatic kidney stones are becoming more common in both men and women," says Andrew Rule, M.D., lead investigator of this study. “This is due in part to the increased use of CT scans to diagnose kidney stones.” More information about the study can be found on Mayo Clinic News Network.
