PERINEAL HERNIORRHAPHY - PERIOPERATIVE DATA FROM 100 DOGS

One hundred dogs (83 intact males, 15 castrated males, and two intact females) underwent 110 perineal herniorrhaphy procedures. Mixed-breed dogs (n=32), miniature poodles (n=14), Boston terriers (n=11), and Pek ingese (n=9) were represented most frequently. Perineal swelling (n=48 ) and a perineal defect on rectal palpation (n=31) were common clinica l signs. Twenty dogs had urinary bladder retroflexion and were signifi cantly more likely to have elevated serum urea nitrogen and creatinine concentrations, hyperkalemia, hyperphosphatemia, and neutrophilic leu kocytosis. Only five of 43 dogs evaluated radiographically had prostat omegaly. Of 30 dogs receiving oral barium, all had rectal deviation. T he most frequent complications during the hospitalization period were incisional (n=35), followed by rectal prolapse (n=9), tenesmus (n=8), and depression (n=8). Fifty-six of 70 dogs with follow-up had no compl ications.
