本文旨在研究不同类型肾结石的比例随年龄和性别的变化。根据结石的成分和结构对结石进行分类。根据年龄和性别对结石形成者进行分组，并确定男性和女性在不同年龄段的各种结石的百分比。结果发现，二水草酸钙结石随年龄增长而减少，但仅限于男性。这些结石在男性中也明显占主导地位。羟基磷灰石结石在男性和女性都随着年龄的增长而减少，但女性占主导地位。尿酸结石在男性和女性中均随年龄增长而增加，但男性占主导地位。最后，研究发现，一水草酸钙结石在男性和女性中均随年龄增长而增加。作为一个主要的新奇，这里提出的研究表明，一水草酸钙乳头状结石和一水草酸钙未附着结石之间的区别的重要性，因为其起源的病因因素必须是明确不同的。
The aim of this paper is to study the variations in the percentage of the different types of renal stones with age and sex. Renal calculi were classified according to their composition and structure. Stone formers were divided according to age and sex, and the percentage of each kind of calculi in the different considered age periods for men and women were determined. It was found that calcium oxalate dihydrate calculi decreased with age, but only in men. These calculi were also clearly predominant in men. Hydroxyapatite calculi decreased with age in both men and women, but they were predominant in women. Uric acid calculi increased with age in both men and women, but were predominant in men. Finally, it was found that calcium oxalate monohydrate unattached calculi increased with age in both men and women. As a main novelty, the study here presented demonstrates the importance of distinguishing between calcium oxalate monohydrate papillary stones and calcium oxalate monohydrate unattached stones, since the etiologic factors responsible for their origin must be clearly different.
