ABSTRACT

The ureters extend caudoventrally to the dorsolateral aspect of the neck of the urinary bladder (Figure 7.7 and Figure 7.8). The urinary bladder is large and thin walled but typical in morphology. It receives its innervation from S2 to S4. The urethra courses along the pelvic floor into the penis. The tip of the penis is located on the ventral abdominal wall in a preputial diverticulum. The external opening of the preputial diverticulum is located immediately caudal to the umbilicus. The contents of this structure must always be expressed prior to performing abdominal surgery in male swine. The desquamated cells and urine in the preputial diverticulum are foul smelling and contaminated with bacteria. Gloves should be worn during the expression of this material (Hodson, 1986; Russell et al., 1981; Swindle, 1983; Swindle et al., 2000; Swindle and Olson, 1988; Terris, 1986).
