Abstract:
Objective To investigate the effects of gemstone energy spectrum CT atomic number method and infrared spec-troscopy for analyzing the composition of urinary calculi and to compare their values in qualitative diagnosis of urinary calculi .Meth-ods Two hundreds and sixty cases of urinary tract stones were performed the gemstone spectrum CT urinary scanning and the stone composition was identified by atomic number method .After removing stone ,the stone composition analyzed by infrared spec-troscopy served as the gold standard .Then the consistency identified by the two methods was analyzed .Results The Kappa consis-tency test results showed that the two kinds of method for identifying stone type had good consistency (Kappa=0 .787 ,P<0 .01) . The paired chi square test results showed that the difference of the two methods for identifying the stone type had no statistical sig-nificance(χ2 =6 .581 ,P=0 .254) .The stone crystal composition types measured by gemstone energy spectrum CT atomic number method were less than those measured by infrared spectroscopy .The precise quantification of the stones with different crystal struc-tures was not as accurate as that of infrared spectroscopy (calcium oxalate monohydrate and calcium oxalate dihydrate ) .Conclusion The two methods for analyzing theurinary stone composition all have clinical significance ,the stone analysis method should be se-lected according to the actual situation .
