In the urine the crystal presence has little clinical meaning; although its correct identification is of utility in pediatric, due to it provide information for the diagnosis of systemic sufferings, diseases of the urinary routes and possible congenital errors of the metabolism. In order to evaluate the influence of the gender, etario group, socioeconomic condition and the anthropometric nutritional state on the prevalence of cristaluria, 381 apparently healthy children were evaluated; age 1 to 18 years, taken care in three of the ambulatory of the Guacara Municipality, Carabobo State. Was determined anthropometric nutritional state by means of weight/age, carves/age, weight/ carves, greasy area and muscular area in suckling babies, preschool and school students; corporal mass index for adolescents; socioeconomic level measured by modified Graffar. Analysis of urine by optical microscope (400x). Statistical SPSS version 10.1 significance p<0.05. Of the total of studied population 49.1% presented cristaluria, with prevalence in preschool and adolescents (33.2% and 26.2% respectively), with statistically significant predominance in boys (57.8%). The crystal prevalent was the oxalate of calcium in 66.8%, with a statistically significant relation between type of crystal, etario group and socioeconomic layer. In the anthropometric nutritional state was 16,6% of undernourishment. Predominance of socioeconomic layer IV in all the etarios groups. We concludes that cristaluria found in this pediatric population of low socioeconomic level, is independent of the anthropometric nutritional state, although other factors like etario group, gender and socioeconomic level are associated.
