بررسی فراوانی نسبی برخی ترکیبات شیمیایی تشکیل دهنده سنگ های مجاری ادراری در بیماران مراجعه کننده به آزمایشگاه های تشخیص طبی استان خوزستان

Background and objectives: kidney stone is a very common disease with the prevalence of 4-7% in the world. the rate of this disease in iran is higher than the global maximum. so it is important to analysis the composition of renal stone in different nations to prevent the formation of stone or to stop its enlargement. also, the first choice for diagnosing renal stone is the most sensitive method; so knowing about the kind of prevalent stones will help to save time and costs. hence, this study was conducted to determine the chemical constituents of urinary tract stones and aimed to find relative abundance of urinary calculi by considering their composition. subjects and methods: in this descriptive-analytic study which was conducted in ahvaz jundishapur university of medical sciences, 275 renal calcuili from patients, 201 male and 74 female, referred to medical laboratories in khuzestan province were collected and after microscopically characterization, their chemical components were analyzed by using the standard methods of clinical laboratory. results: finding show that the stone of 55 patients (20%) of total patients had pure chemical component of calcium oxalate and 220 urinary stones from patient (80%) had a mixed type. also, calcium oxalate was the commonest component of the mixed stones (83.6%).conclusion: our study indicated that the calcium oxalate stones are the most abundant chemical composition of either pure or mixed urinary calculi in khuzestan areas, which are more common in men and struvite stones contain magnesium, ammonium, and phosphate is more common in women.
