Abstract
Sixteen cows with urolithiasis showed higher serum urea nitrogen (SUN) values (mean, 43.1 mg/dl) than 42 unhealthy cattle (mean, 18.5 mg/dl). Generally, high SUN values and liver disturbances were seen in both groups of cows. Calculi were found in the urethrae of all the 16 cows and in the bladder in 15 cows. Urocystitis was seen in 8 cows. Six cows contained calculi in the kidney, showing high SUM values.
SUN value was more than 60 mg/dlin 5 of the 16 cows. Rupture of the bladder was found in 4 of the 5 cows, which had suffered from urinary stasis and uremia.
