title: Dysuria associated with urethral caruncle in the dog.
abstract: Three cases of urethral caruncle were recognized in bitches with a history of chronic dysuria. Clinical and radiological examinations revealed the presence of inoperable lesions involving much of the urethra in all three cases. At post-mortem examination of Case 1, an oval swelling, 1.5 x 1.0 cm, was detected within the wall of the urethra close to the vagino-urethral orifice. In Case 2, firm, mottled yellow, white and red tissue formed a thickening between the urethra and vagina. In Case 3, a cylindrical cream mass, 8 cm long and 3 cm in diameter, surrounded the urethra and impinged on the wall of the vagina. Histologically, glandular structures lined by a single layer of epithelial cells and a mixed granulomatous inflammatory reaction were present in the wall of the urethra of all three cases.
