Comparação do tamanho dos urólitos através da radiografia e ultrassonografia

Abstract

Urolithiasis is a common problem in veterinary clinics. Its treatment depends on the location, composition and size of the uroliths. Imaging tests are used for this purpose. Due to the availability of ultrasound, this has been the first choice in cases of suspected urolithiasis. However, it is known that the size of uroliths is overestimated using this method. Therefore, this study aims to compare the size of stones using radiography and ultrasound. For this purpose, the database of the Imaging Diagnosis Sector of the Veterinary Hospital of the Federal University of Uberlândia was used to select cases diagnosed with urolithiasis, for evaluation and comparison of the size of the stone using radiographs and ultrasound (considering the hyperechoic surface and the measurement of the acoustic shadow). It was found that the urolith can be measured with greater accuracy using the measurement of the hyperechoic surface compared to the acoustic shadow, with radiography being better for cases of multiple stones.
