Gender Distribution of Pediatric Stone Formers

Abstract

Recent epidemiologic evidence suggests that the gender prevalence among adult stone‐formers is changing, with an increasing incidence of stone disease among women. No similar data have ever been reported for the pediatric stone‐forming population. We performed a study to define the gender distribution among pediatric stone‐formers using a large‐scale national pediatric database. Our findings suggest that gender distribution among stone formers varies by age with male predominance in the first decade of life shifting to female predominance in the second decade. In contrast to adults, females in the pediatric population are more commonly affected by stones than are males. The incidence of pediatric stone disease appears to be increasing at a great rate in both sexes. Further studies should build on this hypothesis‐generating work and define the effects of metabolic and environmental risk factors that may influence stone risk in the pediatric patient population
