A Dog with Dysuria Caused by Foreign Body Obstruction in the Prostatic Urethra

Abstract

A 13-year-old male miniature Dachshund was presented for evaluation of voiding difficulty. Prostatic inflammation or a tumor was suspected after a series of diagnostic imaging examinations, but biopsy by transabdominal cystoscopy revealed a fibrous foreign body obstructing the prostatic urethra. A laparotomy was performed to remove the obstruction, and the symptom subsided postoperatively. Because the dog had previously undergone surgical repair of a perineal hernia, we concluded that a piece of cotton used during the surgery had entered the prostatic urethra and caused urethral obstruction.
