Chemical Composition of Urinary Stones in Jeddah: A Study of 441 Samples and a Proposed New Classification
In the present study, the proposed classification of urinary stones is based on the% composition of ions in 441 stone samples subjected to wet chemical analysis for the determination of oxalate (1), phosphate (2), and urate (3). Calcium, Mg, and Na were measured by atomic absorption spectrophotometry (4). Ammonia and carbonate (3) were analyzed qualitatively. In addition, elemental microanalytical determination of total nitrogen (N), carbon (C), and hydrogen (H) was carried out using modifications of the standard methods (5).
