Abstract
|
|
|
|
A 14-year-old, castrated male mixed-breed dog weighing 9 kg was presented for hematuria and dysuria. Abdominal ultrasound showed unilateral hydronephrosis and hydroureter with focal thickening of the ureteral wall. Surgical exploration revealed an intraluminal mass arising from the proximal left ureter. Mass resection was performed. Histopathology of the ureteral mass was consistent with a papillary transitional cell carcinoma. The patient recovered well post-operatively, but was diagnosed with another tumor three months later, this time in the right kidney. Fineneedle aspiration cytology of the renal mass revealed an epithelial cell tumor with mesenchymal features.
