Abstract

Neoplasms of the tubular reproductive tract in female dogs represent a total of 2-3% of canine neoplasms, of which 85-90% occur in the vagina and vulva. Fibroleiomyoma is a benign tumor, generally non-invasive, non-metastatic and slow-growing. The choice of surgical approach for treatment will depend on the degree of involvement of adjacent structures and the size of the neoformation. Therefore, the objective is to report the clinical and pathological aspects of fibroleiomyoma and to describe the partial vestibulovaginectomy (PVV) associated with neourethrostomy in a female dog. For diagnosis, tumor delimitation, and surgical planning, computed tomography was performed. The surgery was performed in two stages, the first of which consisted of performing a median retroumbilical celiotomy to free the uterine stump of adhesions. The second consisted of performing an episiotomy to expose the anatomical structures, tissue divulsion, retroflexion of the vagina, ligation, and removal of the entire portion affected by the neoplasm. It was necessary to perform a neourethrostomy, since the neoformation involved the urethral ostium. The main postoperative complications observed were urinary incontinence and uremic dermatitis near the new urethral ostium. Partial vestibulovaginectomy associated with neourethrostomy is an effective and feasible approach in the treatment of extensive neoplasms of the genitourinary tract in female dogs.
