Summary
Ureteral fibroepithelial polyps in dogs present with urinary issues and can cause ureteral dilation and hydronephrosis. Surgical removal offers a good prognosis for this condition, which resembles the human counterpart.
Area of Science:
- Veterinary Medicine
- Canine Urology
- Surgical Pathology
Background:
- Fibroepithelial polyps are rare ureteral masses in dogs.
- This report details four cases of ureteral fibroepithelial polyps in middle-aged to older dogs.
Observation:
- Dogs presented with clinical signs including urinary incontinence, infections, polydipsia, and pollakiuria.
- Diagnostic imaging revealed ureteral dilation and hydronephrosis secondary to intraluminal masses.
Findings:
- Histopathology showed polypoid lesions with fibrovascular stroma and transitional epithelial cells, consistent with fibroepithelial polyps.
- Lesions were attached by a stalk, with varying degrees of lymphoplasmacytic inflammation.
Implications:
- Surgical intervention, such as ureteronephrectomy or ureteral resection and anastomosis, led to a good prognosis.
- The condition's similarities to human ureteral polyps suggest potential comparative research avenues.
