Summary
A rare canine ureteral hemangiosarcoma was surgically removed, preserving the kidney and ureter. This case highlights successful kidney-sparing surgery for obstructive urinary tract tumors in dogs.
Area of Science:
- Veterinary Oncology
- Urologic Pathology
Background:
- Primary ureteral hemangiosarcoma is an exceptionally rare tumor in dogs.
- This case presents a diagnostic and therapeutic challenge in veterinary urology.
Observation:
- A 13-year-old mixed-breed dog presented with obstructive symptoms including vomiting and abdominal discomfort.
- Imaging revealed a ureteral mass causing significant dilation of the renal pelvis and ureter.
- Histopathology confirmed a primary ureteral hemangiosarcoma.
Findings:
- Complete surgical resection of the ureteral mass was achieved.
- Ureteral suturing successfully preserved the integrity of the urinary tract.
- The dog experienced a two-year survival with preserved renal function.
- Chemotherapy was not administered due to the localized nature of the tumor.
Implications:
- Surgical ureteral mass resection is a viable option for preserving kidney and ureter function.
- Ureteral hemangiosarcoma should be considered in the differential diagnosis of upper urinary tract obstruction in dogs.
- Kidney-sparing surgical techniques can lead to favorable outcomes in select cases of canine urologic tumors.
