Abstract

In the past 4 years, we used infrared spectroscopy to analyze 728 urinary calculi. The most common component of pure urinary calculi was calcium oxalate (whewellite and weddellite) 8.65%, followed by calcium phosphate (carbonate apatite, brushite and amorphous calcium phosphate) 6.87%, uric acid 5.91% and struvite 2.75%. The majority of urinary calculi had mixed components: whewellite/apatite 28.98%, weddellite/apatite 24.31% and whewellite/weddellite/apatite 14.42%. Only 3 cystine stones were found (0.41%). Good correspondence (82.7%) was noted when the results of 110 urinary calculi analyzed by infrared spectroscopy were compared with the results of polarization microscopy. The advantages and disadvantages of infrared spectroscopy are also discussed.

摘要

在过去4年里，我们使用红外光谱法分析了728块尿结石。纯尿结石最常见的成分是草酸钙（文石和水草酸钙）8.65%，其次是磷酸钙（碳酸磷灰石、透钙磷石和无定形磷酸钙）6.87%，尿酸5.91%，鸟粪石2.75%。大多数尿结石有混合成分：文石/磷灰石28.98%，水草酸钙/磷灰石24.31%，文石/水草酸钙/磷灰石14.42%。仅发现3块胱氨酸结石（0.41%）。将110块经红外光谱法分析的尿结石结果与偏振显微镜检查结果相比较时，发现二者具有良好的一致性（82.7%）。同时还讨论了红外光谱法的优缺点。
