His previous medical history included a diagnosis of masticatory muscle myositis in March 2005, which was being treated with immunosuppressive doses of prednisone. One day prior to presentation, his owner noticed a change in Peter's urine stream and brought him to a veterinarian. Urinary catheterization was done and the dog's bladder was emptied. A sustained erection (priprism) and paraphimosis occurred after catheter removal. Upon presentation to Cornell, the paraphimosis was manually reduced. However, the penis remained engorged and inflammed. Imaging studies were taken to investigate penile vascular integrity and evaluate the stranguria. All imaging studies were normal with no evidence of calculi or structural abnormalities. Management of penile edema consisting of urethral catherization and topical DMSO was unsuccessful. Penile amputation, castration, and scrotal urethrostomy were performed two weeks after admission. Post-operatively, Peter became anemic and was given a DEA 1.1 negative packed red blood cell transfusion. Urinary catheter tip culture revealed growth of Pseudomonas aeruginosa sensitive only to Enrofloxacin. After three weeks of antibiotic therapy, two urinary cultures were negative for bacterial growth. Stoma suture removal was uneventful and Peter has been urinating well through the stoma with no evidence of blood or stranguria. His attitude and activity level have been wonderful according to his owner.en-USDogs -- Diseases -- Case studiesDogs -- Surgery -- Case studiesterm paper
