Hypercalciuria in School-Aged Children of Rasht: a Single-center Study

Abstract

Hypercalciuria is the most common identifiable metabolic cause of calcium kidney calculus disease. Idiopathic hypercalciuria is defined as hypercalciuria with normal serum electrolytes levels in the absence of any known underlying disease responsible for increased urinary calcium excretion. The aim of the present survey was to study the prevalence of urinary tract signs and symptoms of idiopathic hypercalciuria in a healthy group of primary school children living in Rasht, a city in north of Iran. The prevalence of idiopathic hypercalciuria in our study was estimated to be 5.6%. This is a first report of idiopathic hypercalciuria in Guilan province.
