Abstract:

【Abstract】 Objective To provide theoretical basis of clinical personalized treatment and prev-ention recurrence for patients with urinary stones,.using infrared spectrum method to analyze the urinary stones composition in Nanhai District,.Guangdong Province.Method The urinary stones in 986 cases were excluded naturally or performed extracorporeal shock-wave lithotripsy,.which were analyzed by the infrared spectrum method.Results Urinary stones were more often found in male patients than that in female,.and the ratio was 1.34∶1 The incidence of urinary tract stones between 51-60 years old were higher than any other age stage. The upper urinary tract stones were more frequently found than the lower urinary tract stones,and the ratio was 9.49∶1. Six types of chemical components were detected in calculi.There were calcium oxalate monohydrate, calcium oxalate dihydrate, carbonated apatite, anhydrous uric acid, hexahydrate phosphate magnesium ammonium and cystine. Mixed components stones were found in 647 cases,.accounting for 65.6%. And calcium stones were found in 853 cases,.accounting for 86.51%. The detection rate of calcium oxalate was highest in all the chemical components,accounting for 77.38%,.followed carbonated apatite (5.27%) and uric acid composition (15.8%). Conclusion It is significant to analyze the urinary stone composition for investigating the cause of stones,.and preventing stone formation and recurrence.
