Resumo
A urolitíase é um termo usado para descrever as causas e os efeitos dos urólitos no
trato urinário. Apesar de ser considerada uma doença comum do trato urinário de cães e gatos,
a urolitíase não deve ser vista como uma doença isolada, mas sim como uma consequência
resultante da interação de várias anormalidades. A previsão da composição dos urólitos é
essencial para determinar o tipo de tratamento (cirúrgico ou médico) e as medidas preventivas
adequadas a cada paciente. Através da realização de radiografias, é possível prever a
composição mineral dos urólitos, avaliando a radiopacidade, a uniformidade da radiopacidade,
o tamanho, a forma, o contorno da superfície e a sua localização.
O Minnesota Urolith Center desenvolveu em parceria com a Hill’s uma aplicação,
denominada de MN Urolith Center, que possui uma calculadora que fornece uma avaliação
preliminar da probabilidade de um urólito ser de estruvite a partir de uma imagem radiográfica.
Este estudo tem como objetivo avaliar a concordância entre os resultados dados pela
calculadora da aplicação MN Urolith Center e a análise quantitativa dos urólitos radiografados
em cães e em gatos, no sentido de verificar se o uso desta ferramenta da aplicação poderá ser
uma mais-valia na prática clínica, uma vez que pode ajudar na tomada de decisões entre o
tratamento médico e o tratamento cirúrgico.
Para tal, foram recolhidos dados de 10 cães e de 5 gatos com diagnóstico de urolitíase
por radiografia abdominal e respetiva análise quantitativa dos urólitos radiografados.
Em cães, os resultados obtidos no presente estudo, mostraram existir um grau de
concordância de 90% entre a calculadora da aplicação MN Urolith Center e a análise
quantitativa dos urólitos radiografados. Em gatos, o grau de concordância foi de 80%.
Com este estudo podemos concluir que, em cães, existe uma associação
estatisticamente significativa entre os resultados dados pela aplicação e a análise quantitativa
dos urólitos que não está presente em gatos.
O presente projeto constituiu o primeiro estudo sobre a calculadora da aplicação MN
Urolith Center.
Urolithiasis is a term used to describe the causes and effects of uroliths in the urinary tract. Although it is considered a common disease of the urinary tract in dogs and cats, urolithiasis should not be viewed as an isolated disease, but rather as a consequence resulting from the interaction of several abnormalities. Predicting the composition of the uroliths is essential to determine the type of treatment (surgical or medical) and the appropriate preventive measures for each patient. By performing radiographs, it is possible to predict the mineral composition of the uroliths by evaluating the radiopacity, radiopacity uniformity, size, shape, surface contour, and location. The Minnesota Urolith Center has developed in partnership with Hill's an application called the MN Urolith Center where there is a calculator that provides a preliminary assessment of the probability of a urolith being struvite from a radiographic image. This study aimed to evaluate the agreement between the results given by the MN Urolith Center application calculator and the quantitative analysis of radiographed uroliths in dogs and cats, in order to verify whether the use of this application tool can be an asset in clinical practice, since it can help in decision making between medical and surgical treatment. To this end, data was collected from 10 dogs and 5 cats diagnosed with urolithiasis by abdominal radiography and respective quantitative analysis of radiographed uroliths. In dogs, the results obtained in this study showed a 90% degree of agreement between the MN Urolith Center application calculator and the quantitative analysis of radiographed uroliths. In cats the degree of agreement was 80%. With this study we can conclude that in dogs, there is a statistically significant association between the results given by the application and the quantitative analysis of the urolytes and that in cats there is no statistically significant association between the results. This project was the first study on the MN Urolith Center application calculator.
