Resumo

Background: Urethral neoplasias are rare in small animals and normally have slow growth, but tissue invasion and urethral obstruction are frequent. Prognosis usually is poor due to the high degree of malignity of the main neoplasias involved. Surgical excision is the main form of treatment, but it should be complete with wide safety margins, making partial or complete removal of the bladder with transplantation of the ureters necessary. This report aims at describing a surgical technique, used in a bitch with urethral tumor, which involved complete resection of vulva, vagina and bladder, followed by ureterocolic anastomosis without pelvic osteotomy.Case: A 10-year-old female White Swiss Shepherd dog, weighing 35 kg, was presented with partial ischuria and haematuria for approximately 30 days, with fi nal development of complete ischuria, vomit and anorexia. Urethral swab was performed, and the material obtained was fi xed for cytological examination, which revealed the presence of malignant epithelial neoplasias, giving the case a direction. Staging was achieved through thoracic radiographs in two recumbent views, and metastatic lesions were not found. A radical surgery was proposed to the owner for the treatment of the patiente. The surgical procedure involved complete removal of the lower urinary tract, vagina and vulva, followed by reimplantation of the ureters in the colon
