Abstract
ABSTRACT: The purpose of this paper was to describe obstructive urolithiasis with uroperitoneum and hydronephrosis in range cattle in southern Rio Grande do Sul. The disease was observed in castrated male cattle, aged between 18 months and 3 years in a herd of 200 steers that were in a ryegrass pasture during the winter and a native pasture during the summer. Different mineral salts were used as a supplement for the animals during the two seasons of the year. Cattle presented a progressive abdominal distention, depression and dehydration ranging from 10 days to one month in duration. One animal was necropsied, and approximately 50 liters of urine (uroperitoneum) in the abdominal cavity were observed. The bladder had a small rupture and was adhered to the pelvic cavity. The right kidney was enlarged with hydronephrosis. Uroliths of more than 1cm in diameter were housed in the penile urethra. In this study, the disease occurred probably because of mineral salt supplementation, resulting in an imbalance of calcium and phosphorus intake.
