RESUMEN
There are many underlying factors that increase the chance for occurrence of UTI and some reports indicate a role for hypercalciuria in UTI. The objective of this study was to assess the Ca/Cr status in urinary tract infection of children. This was a cross-sectional antegrade study conducted in Qods teaching hospital of Qazvin from 2006-2007, in which 50 children with urinary tract infection were studied for hypercalciuria. To determine hypercalciuria, the Ca/Cr ratio of a random urine sample was measured. Different variables such as age, gender, history of UTI and etc, were compared between hypercalciuric and normocalciuric groups. Results were analyzed with SPSS using t-test and chi square test. Of 50 patients, 27 cases [54%] were found to have hypercalciuria. There was a significant difference between hypercalciuric and normocalciuric groups regarding the abnormal sonographic findings [p<0.05]. Based on results of this study evaluation of hypercalciuria in UTI is recommended
