RESUMO
BACKGROUND: This study aims to describe a rare case of primary ureteral hemangiosarcoma, in which surgical intervention preserved the kidney and ureter after tumor removal. CASE PRESENTATION: A 13-year-old, neutered male dog, weighing 14 kg, mixed-breed, presented with apathy, anorexia, acute-onset vomiting, and abdominal discomfort during the physical examination. Ultrasonography and pyelography revealed a right-sided dilation of the renal pelvis and ureter due to complete obstruction in the middle third of the ureter. A mass obstructing the lumen of the right ureter was completely resected, and ureteral suturing was performed, preserving the integrity of the involved structures. Histopathology confirmed primary ureteral hemangiosarcoma. Due to the local and non-invasive nature of the mass, chemotherapy was not initiated. The patient's survival was approximately two years, and normal renal function was preserved throughout this period. CONCLUSIONS: Considering this type of tumor in the differential diagnosis of upper urinary tract obstructive disorders. Furthermore, the preservation of the ureter and kidney is a suitable therapeutic option after surgical resection of non-invasive tumors.

The efficiency of the mesh graft used in lacerating wound was evaluated when comparedto another wound treated by second intention. The debridement of the wound wasperformed, the necrotic tissue was removed for subsequent granulation tissue formationand graft application. The transplanted skin was collected from the thoracic region with thesame measures of the defect to be corrected. The preparation of the graft consisted of theremoval of adipose tissue, and later, with the use of the scalpel blade, several rectilinearcuts were made, leaving it with mesh pattern. The graft was fixed to the wound with theuse of a separate single suture. After the surgical procedure, a bandage with hydrogel wasapplied to the limb of the animal, where the dressing change occurred at intervals of fourdays. We concluded that the wound treatment in the MTE using the graft was efficient withtotal wound healing when compared to the non-grafted MTD treatment.Palavras-chaves: cirurgia reconstrutiva; plástica; cão.(AU)
