disorders related to tubular acidification function (in the case of carbonate apatite).
FTIR is also effective in the identification of both the crystalline and amorphous nature of a stone, even when analyzing a small amount of sample.
It has been mentioned that using computerized IR spectrophotometer and large reference library enable us to determine exact quantitative stone composition, and this method should be extended to all urolithiasis centers (Singh, 2008).
Chemical methods have repeatedly proved to be unreliable in numerous quality control programs, with error rates in identifying certain components up to 90%.
Our study showed that there was a disagreement between chemical and FTIR stone analysis results that reached up to 70%.
On the contrast the FT-IR does not show a significant variability because it provides an easier and more standardized sample preparation, and the spectrum interpretation is based on strong scientific principles.
The results of our study and the review of the literature recommend the introduction of the FT-IR technique to be the standard method of stone analysis.
