A urolitíase é um problema frequente e nos últimos anos houve um aumento dos cálculos de oxalato de cálcio em cães. Este trabalho tem por objetivo descrever o atendimento de uma cadela com obstrução do trato urinário por cálculos de oxalato de cálcio.
O exame ultrassonográfico constatou que a bexiga estava preenchida por cristais e foi realizada a cistotomia para remoção dos mesmos. Exames laboratoriais, de imagem, bem como avaliação clínica, apontaram informações importantes sobre as causas bases da formação dos urólitos. A partir disso foi instituído um tratamento preventivo para evitar recidivas, que se mostrou efetivo.
