A Case of Urethral Leiomyoma Causing Dysuria in a Dog

Abstract

An 8-year-old neutered male golden retriever was presented for evaluation of dysuria. The dog showed perineal swelling on physical examination. Retrograde positive-contrast urethrography revealed a tennis ball-sized filling defect in the perineal urethra, suggesting a urethral tumor. Surgical removal of the mass was scheduled to relieve the dysuria. The urethral mass was revealed via a perineal midline approach and removed with a surrounding portion of the urethra. The external urethral orifice was reconstructed. The mass was histopathologically diagnosed as a leiomyoma. The dog’s postoperative recovery was favorable and uneventful.
