A seven-year-old Jersey bull used for artificial insemination showed clinical signs of obstructive urolithiasis. This was confirmed by catheterisation and subsequent urethrotomy over the site of obstruction distal to the sigmoid flexure. Although urine flow was elicited after removal of the calculi, this was only temporary and the animal had to be killed 24 hours later. On post mortem examination about 2 kg of round, smooth, pearl-like calculi were found in the urinary bladder and the urethra of the sigmoid flexure was studded with similar calculi. It was concluded that urethrotomy at the sigmoid flexure or penectomy post scrotally would not have alleviated this condition.
一头用于人工授精的七岁泽西公牛出现了阻塞性尿路结石的临床症状。通过导尿以及随后在乙状结肠弯曲远端阻塞部位进行尿道切开术得以确诊。尽管结石取出后尿液能够排出，但这只是暂时的，24小时后这头动物不得不被安乐死。尸检发现膀胱中有约2千克圆形、光滑、珍珠样的结石，乙状结肠弯曲处的尿道也布满了类似的结石。得出的结论是，在乙状结肠弯曲处进行尿道切开术或阴囊后阴茎切除术并不能缓解这种情况。
