A one year old Angus steer presented to the Cornell University Equine and Farm Animal Hospital for evaluation of a two month history of hematuria, stranguria, and intermittent penile pain and swelling. Evaluation by the surgery and theriogenology services at Cornell revealed an edematous prepuce, a dilated urethra that contained hyperechoic material, and phimosis. A chemistry panel revealed mild azotemia and urinalysis showed hyposthenuria. On ultrasound, the right kidney was enlarged with dilated renal calyces and a mild to moderate amount of perirenal fluid. The problem list included phimosis, urinary incontinence, preputial edema, azotemia, hyposthenuria, an enlarged and distended bladder, unilateral hydronephrosis and perirenal fluid (right kidney), and urethral dilation with regions of hyperechogenicity. Endoscopy of the prepuce revealed preputial and penile fibrosis. This report will discuss the differentials for phimosis in a steer and current techniques in bovine reproductive surgery.
