Fixation of the deferent ducts for retrodisplacement of the urinary bladder and prostate in canine perineal hernia.

The deferent ducts were secured to the lateral abdominal wall in nine dogs to correct retrodisplacement of the urinary bladder and prostate. Perineal herniorrhaphy and fixation of the deferent ducts were performed in seven dogs; in two dogs, only fixation of the deferent ducts was performed. All dogs were clinically normal after 4 to 28 months (mean, 14.7 months).
