Study purposes were to evaluate ultrasonographic characteristics of transitional cell carcinoma (TCC) and quantitate bladder tumor size in dogs. Heterogeneous mass, wall involvement, and broad-based attachment were significantly associated with TCC, but not prominently the trigone region. Mass size evaluation revealed a significant correlation between progressive disease (PD) in TCC patients with piroxicam therapy. Largest diameter of target lesion/ body weight (cm/kg) ratio showed a high mean value in PD. A value greater than 0.3 was associated with PD with 83% sensitivity and 66% specificity. The results suggest that ultrasonography can provide evidence for diagnosing and predicting a prognosis for TCC.
