What Is Your Diagnosis?

摘要

A 4-year-old male domestic shorthair cat was referred to the veterinary teaching hospital for evaluation of anorexia, signs of depression, and dehydration secondary to urinary obstruction of 4 days'- duration. After relieving the obstruction, positive-contrast urethrocystography was performed. Irregularity of the pelvic urethra and a focal decrease in urethral diameter at the level of the acetabula were evident on both views; however, there was no evidence of extravasated contrast material. The radiographic diagnosis was urethritis, with possible urethral stricture Perineal urethrostomy was performed. During the urothrostomy, longitudinal urethral tears were noticed extending cranially beyond the surgical site. Therefore, a 6-F foley catheter was placed from the surgical site into the urinary bladder During the next 14 hours, the cat had no interest in food and could not maintain a stable body temperature. In addition, the bladder was palpably distended, but could not be adequately drained via manual compression or cystocentesis Positive-contrast cystograp.hy was repeated, using the urinary catheter that was placed during the urethrostomy (Fig 1).
