Prescrotal urethrotomy for urethroscopic ablation of a hemorrhagic urethral mucosal mass.

A 7-year-old neutered male Staffordshire bull terrier dog was presented for investigation of chronic profuse urethral hemorrhage. A vascular mucosal mass lesion was identified in the proximal penile urethra on ultrasound examination; prescrotal urethrotomy was performed to allow rigid urethroscopy and mass removal. Histopathological changes were consistent with proliferative urethritis. Key clinical message: Prescrotal urethrotomy to facilitate rigid urethroscopy has not been previously described and is a useful technique to allow visualization of the male canine proximal penile urethra distal to the pelvic flexure. Proliferative urethritis is an important differential diagnosis for dogs presenting with profuse urethral hemorrhage.
