Introduction. The aim of this study was to evaluate demographic data and clinical features of nephrolithiasis in children. Materials and Methods. We retrospectively collected the clinical finding and metabolic risk factors of 132 children (52 girls and 80 boys) with nephrolithiasis, between 2009 and 2012. Clinical presentation, urinary tract infection, calculus localization, family history and metabolic risk factors were noted. Results. The mean age of children were 6.8 ± 3.9 years.In 69 % of the cases, the calculus was located only in the kidneys (unilaterally) and 20.4 % was bilaterally. The most common presentations were macroscopic hematuria,abdominal pain and restlessness.A positive family history of urinary calculi was detected in 40.9 %; urinary tract infection, in 43 cases and recurrent calculus in 14.3% of patients. Metabolic evaluation was as follows: hypercalciuria in 76 cases, cystinuria in 11, hyperoxaluria in 18 .Three of the 11 patients with cystinuria were then diagnosed as cystinosis. Conclusions. We think that nephrolithiasis remains a serious and increasing problem in children in our country. Family history, metabolic disorders and urinary tract infections tend to be associated with childhood nephrolithiasis.
