背景和目的肾结石是异质性的，但往往聚集在一起。设计、设置、参与者和测量研究了2010年期间患者提交给马约诊所金属实验室进行分析的第一块结石（n= 43，545）。结果草酸钙结石（67%）最常见，其次为羟基磷灰石（16%）、尿酸（8%）、鸟粪石（3%）、透钙磷石（0.9%）和胱氨酸（0.35%）。男性比女性占更多的石头提交（58%）。然而，在10-19岁（63%）和20-29岁（62%）之间，女性提交的钻石数量多于男性。女性以羟基磷灰石（65%）和鸟粪石（65%）结石为主，而男性以草酸钙（64%）和尿酸（72%）结石为主（P
Background and objectives Kidney stones are heterogeneous but often grouped together. The potential effects Of patient demographics and calendar month (season) on stone composition are not widely appreciated.Design, setting, participants, & measurements The first stone submitted by patients for analysis to the Mayo Clinic Metals Laboratory during 2010 was studied (n=43,545). Stones were classified in the following order: any struvite, any cystine, any uric acid, any brushite, majority (>= 50%) calcium oxalate, or majority (>= 50%) hydroxyapatite.Results Calcium oxalate (67%) was the most common followed by hydroxyapatite (16%), uric acid (8%), struvite (3%), brushite (0.9%), and cystine (0.35%). Men accounted for more stone submissions (58%) than women. However, women submitted more stones than men between the ages of 10-19 (63%) and 20-29 (62%) years. Women submitted the majority of hydroxyapatite (65%) and struvite (65%) stones, whereas men submitted the majority of calcium oxalate (64%) and uric acid (72%) stones (P
