Objective: Idiopathic hypercalciuria ( IHC ) is very frequently seen metabolic disorder in children and causes to some symptoms as hematuria, disuria, enuresis, cholic pain and growth retardation. IHC is generally ended with urolithiasis ( 1-2 ). In this researh , we aim to notice frequency and clinically importance of hypercalciuria.                 Method: In pediatric polyclinic, 4 to 15 year old children detected for hypercalciuria by calcium, creatinine, sodium and potasium measuring in spot urine samples. we calculated the urine calcium creatinine ratio( Uca/Ucr ) and 0,20 and above accepted hypercalciuria ( 3 ). Urinary tract symptoms were recorded.                 Results: We studied 223 children in our pediatric polyclinic with an age range of 4 to 15 years (mean= 8.7 ±3,18.7 ±3,1).  124 ( %55.6) chidren were female and 99 ( %44.4 ) were male. In study group,  we found urine calcium creatinine  ratio  0,20 and above in 32 (%14.3 ). The prevalance was %18.2 in males and in females was  %11.3. 92(%41.3) children were have urinary system symptoms and hypercaluria was found in 25( %27.2 ) from these 92 symptomatic children. Of all hypercalciuric 32 children, 25( %78.1 ) children were symptomatic and the most frequently symptoms was abdominal pain with %68.8 frequency ( 22 children ). However in nonhypercaiuric 191 children abdominal pain was found 47( %24.6 ) children, from hypercalciuric children 22( %68,8 ) patients had abdominal pain ( p<0,001). The mean sodium creatinine ratio, in hypercalciuric children was 3,71±3,62 and in nonhypercaiuric was 1,70±1,28 (p<0,001).                 Conclusions: Because of the IHC frequently ended in urolithiasis, especially in urinary tract sympomatic children Uca/Ucr should be studied that is not invasive test and patients with IHC can be treated firstly with sodium restricted and potasium richly diets.
