Abstract：
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.
METHODS: 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.

摘要：
背景：本研究旨在描述一例罕见的原发性输尿管血管肉瘤，其中手术干预保留了肿瘤切除后的肾脏和输尿管。
方法：13岁，绝育的雄性狗,重14公斤，混血儿,带着冷漠，厌食症,急性呕吐,体格检查时腹部不适。超声检查和肾盂造影显示，由于输尿管中段完全阻塞，肾盂和输尿管右侧扩张。阻塞右输尿管管腔的肿块被完全切除，进行了输尿管缝合，保持所涉及结构的完整性。组织病理学证实原发性输尿管血管肉瘤。由于肿块的局部和非侵入性，化疗尚未开始.病人的生存期大约是两年,在此期间保持了正常的肾功能。
结论：考虑该类型肿瘤在上尿路梗阻性疾病中的鉴别诊断。此外，手术切除非侵入性肿瘤后，保留输尿管和肾脏是一种合适的治疗选择。
