Frequency of Kidney Stone Different Compositions in Patients Referred to a Lithotripsy Center in Ilam, West of Iran
Introduction: Ilam is one of the provinces with the highest prevalence of kidney stone. The aim of this study was to calculate the frequency percentage of kidney stones by composition in Ilam.Materials and Methods: This cross-sectional study was conducted on 160 patients referred to the lithotripsy center of Ilam for the treatment of kidney stones from 2014 to 2015 (9 months). A two-part questionnaire including demographic information and stone type was used for collecting data. Finally, the obtained data were analyzed with SPSS version 17.Results: The frequency of kidney stones was 68% in men and 31.8% in women. The prevalence of kidney stones was higher in men than women, but there was no significant relationship between gender and the stone type. The highest prevalence of the stone was in the age group 31-41 years (33.7%) and there was a significant relationship between age and the stone type (P=0.001). The frequency of calcium oxalate (CaOx), mixed, uric acid, and cysteine kidney stones was 61.25%, 36.25%, 1.9%, and 0.6%, respectively. The most prevalent mixed stone was uric acid together with calcium oxalate stones (21.8%) followed by CaOx together with calcium phosphate stones (10.6%).Conclusions: The prevalence of CaOx and uric acid and CaOx stones was high. It is likely the increase in mixed stones in Ilam, especially uric acid and CaOx stones, is due to the nutritional pattern of subjects. More studies are required to determine the relationship between the stone type and diet in this area.Keywords: Kidney stones; Nephrolithiasis; Urolithiasis; Calcium phosphate; Calcium oxalate; Struvite; Uric aci
