ResumoespanolSe describe un foco de urolitiasis obstructiva en un corral de engorde ocurrido en Setiembre de 2010 en el departamento de Paysandu, Uruguay (Latitud 31o53’0,03”S; Longitud 57o3’24,46”O). Se afectaron 132 novillos de 2 a 3 anos de raza Hereford y Cruza, que recibian una dieta con concentrados en base a cereales y premezcla de minerales. Las lesiones mas destacadas en todos los animales se observaron en el sistema urinario: rinones palidos con perdida de diferenciacion cortico-medular y multiples calculos a nivel de pelvis renal. Seis novillos que murieron en el corral presentaban ademas, obstruccion uretral a nivel de la flexura sigmoidea del pene con ruptura de la vejiga urinaria. El analisis de los calculos determino que estaban compuestos por estruvita. El principal factor predisponente para la presentacion de urolitiasis obstructiva en este foco, fue el desbalance mineral de la dieta dado por un consumo alto de concentrados. No se observaron mas casos luego que se implementaron medidas para la prevencion de la urolitiasis obstructiva. EnglishIt is described an obstructive urolithiasis outbreak in feedlot cattle occurred in September 2010, in Paysandu, Uruguay (Latitude 31o53’0.03”S; Longitude 57o3’24.46”O). There were affected 132 Hereford and Crossbreed 2-to-3 year old steers that were fed with a concentrate based on cereals and a mineral premix. The most important lesions in all animals were in the urinary system: pale kidneys without cortex-medullar differentiation and many calculi in the renal pelvis. Six steers that died in the feedlot had also urethral obstruction in the sigmoideal flexure and rupture of the urinary bladder. Calculi analysis determined that it was composed of struvite. Main predisposing factor for obstructive urolithiasis in this outbreak was the imbalance diet trough a high intake of concentrate. There were no more cases since preventive managing measures were implemented.
