ABSTRACT

Introdução: Litíase urinária é a formação de cálculos no trato urinário a partir de componentes presentes na urina. É uma doença crônica associada a um alto número de recorrência e hospitalizações. O objetivo do estudo foi verificar a frequência de cristalúria e a relação entre litíase urinária e os achados de cristalúria e hematúria em pacientes da região noroeste do estado do Rio Grande do Sul. Métodos: Estudo transversal no qual foram incluídos pacientes no período de março a dezembro de 2015. Exames qualitativos de urina e prontuários médicos foram revisados buscando-se dados de cristalúria e hematúria e diagnóstico da litíase. Resultados: Foram analisadas 688 amostras de urina, e 54 (7,85%) apresentaram cristalúria. Dos casos de cristalúria, cinco (9,3%) pacientes apresentaram litíase. Foi verificada significância estatística (p = 0,010) entre as variáveis de litíase e hemácias, mas não foi evidenciada significância estatística entre as variáveis de litíase e cristalúria (AU)


Introduction: Urolithiasis is the formation of stones in the urinary tract from urine components. It is a chronic disease associated high recurrence and hospitalization rates. The aim of this study was to determine the frequency of crystalluria and the relation between urolithiasis and crystalluria and hematuria findings in patients of northwestern Rio Grande do Sul. Methods: A cross-sectional study that enrolled patients from March to December of 2015. Urinalyses and medical records were reviewed searching for crystalluria and hematuria data, and diagnosis of lithiasis. Results: 688 urine samples were analyzed, and crystalluria was found in 54 (7.85%) of them. Considering the crystalluria cases, 5 (9.3%) of the patients also had lithiasis. Statistical significance was found (p = 0.010) between the variables of lithiasis and red blood cells, but no statistical significance was found between the variables of lithiasis and crystalluria. Conclusion: Crystalluria was not associated with lithiasis, while hematuria was associated with such disease (AU)
