背景：肾结石的分类与主要泌尿病因有明确的相关性，之前已经建立。然而，此类信息复杂且难以适应临床常规实践。方法：提出了一种基于肾结石结构和成分的简单分类，并将其应用于 2500 个肾结石，以获得每个类别的百分比。对随机选择的 700 名个体的尿液进行了分析，并将结果与 51 名健康受试者的结果进行了比较。结果：12.9% 结石对应一水草酸钙乳头状结石，16.4% 对应一水草酸钙独立结石，33.8% 对应二水草酸钙结石，11.2% 脱水草酸钙/羟基磷灰石混合结石，7.1% 羟基磷灰石结石，4.1% 鸟粪石结石，0.6%透钙磷石结石、尿酸结石8.2%、草酸钙/尿酸混合结石2.6%、胱氨酸结石1.1%、各种罕见结石1.9%。根据相应的尿液分析研究，每种结石都与更频繁的尿液改变相关。结论：这种分类的一个重要方面是可以通过对微积分的正确研究来确定与其形成密切相关的一些主要可能病因。 2002 Elsevier Science B.V. 保留所有权利。
Background: Classification of renal calculi with clear correlation with the main urinary etiological conditions has been previously established. However, such information is complex and difficult to adapt to clinical routine practice. Methods: A simple classification of renal calculi based on their structure and composition is proposed and applied to 2500 renal calculi to achieve the percentage of each category. The urines of 700 individuals chosen randomly have been analyzed and the results compared with those obtained with 51 healthy subjects. Results: 12.9% calculi corresponded to calcium oxalate monohydrate papillary calculi, 16.4% to calcium oxalate monohydrate unattached calculi, 33.8% to calcium oxalate dihydrate calculi, 11.2% calcium oxalate dehydrate/hydroxyapatite mixed calculi, 7.1% hydroxyapatite calculi, 4.1% struvite calculi, 0.6% brushite calculi, 8.2% uric acid calculi, 2.6% calcium oxalate/uric acid mixed calculi, 1.1% cystine calculi and 1.9% various infrequent calculi. Based on the corresponding urinary analytical studies, each kind of calculus is related with the more frequently associated urinary alterations. Conclusions: An important aspect of this classification is the possibility to establish, by means of the correct study of the calculus, some of the main possible etiologic factors closely related to its formation. 2002 Elsevier Science B.V.
