Internal obturator muscle transposition for treatment of perineal hernia

Perineal hernia results from a weakness of the pelvic diaphragm, allowing herniation of bladder, prostate, intestine, omentum, and colon in the perineal area. Perineal hernias occur most commonly in middle-aged male dogs, which are often sexually intact or castrated late in life. Although no single cause has been identified, the condition is thought to occur as a result of muscular atrophy, neurogenic atrophy, hormonal influence, and tenesmus secondary to prostatic disease or chronic constipation.
