Urolitíase por urato de amônio em dálmata: relato de caso

Abstract

Ammonium urate uroliths is often diagnosed in Dalmatian dogs, due to a genetic predisposition that generates a deficiency in purine metabolism, related to the modification of urine pH, which makes it more acidic and contributes to the formation of these stones. Affected dogs may show clinical signs such as dysuria, frequency and hematuria. It is extremely important to identify the composition and structure of this urolith through quantitative analysis, as it is one of the means of obtaining an accurate diagnosis to start the therapeutic method based on nutritional management, thus avoiding relapses. If not treated correctly, this calculus can generate complications such as patient obstruction, being more common in males. The present work presents a case report on ammonium urate urolithiasis in a Dalmatian, reporting on its formation, genetic issues, diagnosis and appropriate treatment.
