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

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 …

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 …

Materials and Methods Thirty-five excised calculi were obtained from kidneys, ureters, and
bladder; there were nine uric acid, eight struvite(mixed MgNH4PO4 and calcium phosphate) …

Thirty‐six urinary stones were studied by computed tomography and bone densitometry in
order to find a correlation between the chemical composition of the stones and the …

Background and Purpose: The choice of the most efficient treatment modality for renal
calculi could be facilitated by determining the precise chemical stone composition before …

Urinary calculi are often small and can be composed of many different constituents. The
highly variable composition has led to the development of different chemical and physical …

Current physical and chemical methods available for urinary stones analysis are critically
reviewed. No one method is sufficient to provide all the clinically useful information on the …

The clinical management of renal calculi would be aided if a direct in vivo determination of
stone chemical composition could be made. We investigated the possibility of obtaining this …

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 …
