Stones from the upper urinary tract of 172 male and 73 female patients have been analyzed by X-ray diffraction. Pure calcium oxalate stones contribute 39.5% of all stones from men, but only 6.9% of stones from women. This difference is consistent both above and below 50 years of age and largely independent of whether patients with known causes of stone formation are excluded. Other sex differences, such as a greater tendency to pure calcium phosphate and triple phosphate stones in female patients, are to a large extent dependent on demonstrable causes. The possibility of analysis error is discussed, considering the possibility of minor amounts of calcium phosphate being overlooked in "pure" calcium oxalate stones. Although this possibility cannot be rejected, there will still be a definite male preponderance of calcium oxalate stones with no or minimal admixture of calcium phosphate.
对172例男性和73例女性患者上尿路结石进行了X射线衍射分析。纯草酸钙结石在男性所有结石中占39.5%，而在女性结石中仅占6.9%。这种差异在50岁上下均存在，且在很大程度上与是否排除已知结石形成原因的患者无关。其他性别差异，如女性患者中纯磷酸钙和磷酸三钙结石的倾向更大，在很大程度上取决于可证实的原因。讨论了分析误差的可能性，考虑到在“纯”草酸钙结石中可能忽略少量磷酸钙的可能性。尽管不能排除这种可能性，但草酸钙结石仍将明显以男性为主，无或仅有少量磷酸钙混合。
