An 11-year-old MN Australian shepherd was presented for evaluation of progressive polyuria and stranguria. Urinalysis showed abnormal epithelial cells. On survey radiographs, mineralization near the pelvis in area of bladder was evident.

Bladder mass, appears to be local. There was no overt evidence of organ metastasis.
The urinary bladder revealed a mass that occupied the cystourethral junction with initial occupation of the pelvic urethra. Early ureteral obstruction was noted at the trigone. The right and left ureters appeared to be slightly obstructed. This is strongly consistent with transitional cell carcinoma. Microscopic or minor, local metastasis to the prostate is possible even though it appeared uniform at 1.0 cm. The bladder mass does not appear resectable in its position.
Ureteral and urethral stents could be placed in this patient with laser ablation debulking procedure as a salvage approach. Long term prognosis is poor, yet some quality of life may be obtained by interventional radiology procedure. Traumatic catheterization to confirm transitional cell carcinoma would be recommended with ultrasound guidance.
Bladder – neoplasia, urolith, chronic bacterial cystitis
Prostate – neoplasia
