This phenomenon may expose these individuals to osteoporosis. This study evaluated bone mineral density (BMD) in patients with urinary stones in Iran.MethodsThis is an analytical case-control study performed in Sina hospital from March 2016 to January 2018. Twenty-four male patients between 30 and 50 with recurrent urinary tract stones were enrolled in the study. The control group was selected from the same period and sex group with no history of urinary stone formation. The diet was similar in the two groups. The sampling method was non-random. Age and BMI were considered confounding variables. After completing, the questionnaire measured the BMD of the lumbar spine (L4 L2) and the femoral neck. The data were analyzed using linear regression and t-test.ResultsIn both regions, BMD was significantly lower in patients compared to the control group (p-value<0.01). Besides, there was a significant correlation between the duration of urinary stones and BMD in each of the mentioned areas (p-value<0.001, r=-0.73 in the lumbar spine, p-valueConclusionsReduction of bone density in patients with recurrent urinary stones may indicate a primary impairment in the bone metabolism of these individuals. Considering that 30% of patients have osteopenia and, generally, patients with urinary stones are not allowed to use calcium, it is necessary to eliminate calcium from their diets only after complete analysis.}, keywords = {Osteoporosis,Urine,Stone,Bone mineral density}, url = {http://www.transresurology.com/article_106324.html}, eprint = {http://www.transresurology.com/article_106324_2a4056c94112c2c774b63a865cd785f5.pdf} }
