Tóm tắt

OBJECTIVE: The national lifetime prevalence of urolithiasis is estimated at 6.6% in Iran. However, reports on the composition of kidney stones have been based on imprecise methods like the chemical analysis. No prior large-scale study has reported the composition of kidney stones based on the gold-standard methods (X-ray diffraction or infrared spectroscopy) in Iran. This study aimed to provide the composition of kidney stones based on Fourier transform infrared spectroscopy. METHODS: This is a cross-sectional study assessing urinary stone composition from various cities in Iran at a referral center using infrared spectroscopy from February 2019 to March 2023. RESULTS: This study determined the stone composition of 1092 patients from 10 cities in Iran. Overall, the majority of stones were composed of calcium oxalate ( CONCLUSION: The most frequent stone composition among kidney stones in Iran was calcium oxalate and UA stones. This relative frequency of UA stones is considerably higher than many international reports from neighboring as well as distant countries. More cystine stones were observed in children and women. Geriatric patients' stones were mostly composed of UA.
