Sonographic Investigation of Transitional Cell Carcinoma of the Urinary Bladder in Small Animals

This report compares results from imaging of transitional cell carcinoma of the urinary bladder in 15 dogs using intravenous urography, double‐contrast cystography, and ultrasonography. Intravenous urography demonstrated filling defects in the urinary bladder in 3 of the 5 cases examined with this modality. Double‐contrast cystography identified bladder masses in 8 of 10 animals. Ultrasonography was the only imaging modality which detected bladder masses in all patients.
