Urinary calculi are often small (< 5 mg) and can be composed of many very different
constituents. The highly variable composition has lead to the development of many different …

Summary 10 urinary calculi have been qualitatively and quantitatively analysed using X-ray
diffraction, infra-red, scanning electron microscopy, X-ray fluorescence, atomic absorption …

PURPOSE: To compare and evaluate the mostly used methods of urinary stone analysis.

Numerous methods can be used for the analysis of urinary stones, but few of them provide
information on the structure, chemical composition and crystal phases of these stones. In a …

A better understanding of the physico-chemical principles underlying the formation of
calculus has led to a need for more precise information on the chemical composition of …

Analysis of urinary stones is an essential step in establishing the diagnosis and treatment of
the stone patient. In fact, the need for an exhaustive study of the stones increases as the …
