A urethral fistula may develop following laceration of the urethra, constrictive injury from a penile hair ring, or urethral necrosis associated with the presence of a urethral calculus (Figure 15.17). The bull's ability to deposit semen properly in the cranial vagina may be compromised depending on the location of the fistula [33].
