Association between idiopathic hypercalciuria and hematuria, nephrolithiasis or recurrent urinary tract infections in children

Abstract

In order to evaluate the role of idiopathic hypercalciuria (IH) in causing hematuria, nephrolithiasis and recurrent urinary tract infections we studied two groups of children for idiopathic hypercalciuria. 1) Patients group: children with hematuria, nephrolithiasis and recurrent urinary tract infections (n=452). 2) Control group: children with no urinary tract problem (n=100). In control group 3% of children had IH. In patients group 27.5% of patients with hematuria, 37% of patients with nephrolithiasis and 7.9% of patients with recurrent urinary tract infections had IH, P values=0.001, 0.005 and 0.2, respectively. This study confirms that there is a positive association between IH and hematuria or nephrolithiasis, but there is no significant association between recurrent urinary tract infections and IH
