Abstract
Background And Objective: Recurrent urinary tract infection is one of the most common causes of chronic renal failure of children. Therefore diagnosis of predisposing factors in recurrent UTI have an important role to prevent renal damage. There are some studies that focus on the relationship between hypercalciuria and damage to the urinary tract epithelium and voiding disfunction. but there are a few and limited study about association between idiopathic hypercalciuria and recurrent UTI.
Our aim in this study was to evaluate idiopathic hypercalciuria in children with recurrent UTI who has not anatomical problems.
Materials and Methods: During the period of 12 months from September 2003 to September 2004, 46 children who had recurrent UTI without anatomical problems (VUR, renal stone…) we measured 24 hours urine calcium and compared with 46 healthy children as control group.
Results: Hypercalciuria was found in 34.8% children with recurrent UTI and in 8.6% of control group. (P <0/05)
Conclusion: We concluded that idiopathic hypercalciuria is a common finding among recurrent urinary tract infection in children without urinary tract anatomical problems.
