ABSTRACT
<p><b>OBJECTIVE</b>To seek the methods in the prevention and cure of urinary stones in the Zhujiang valley in Guangdong province.</p><p><b>METHODS</b>Twenty random urinary stones were quantitatively and morphologically analyzed by X-ray photoelectron spectroscopy (XPS) and X-ray powder diffraction (XRD).</p><p><b>RESULTS</b>Calcium oxalate (about 70%) was the main composition of urinary stones in the Zhujiang valley in Guangdong province; while 30% of which was uric acid stones. Most calcium oxalate stones contain phosphate; however, its content usually was less than 10%.</p><p><b>CONCLUSIONS</b>Calcium oxalate, uric acid and phosphate are the main compositions of urinary stones in the Zhujiang valley in Guangdong province. The compositions and phases of urinary stones can be obtained accurately by the combination of XPS and XRD.</p>
