Photodynamic therapy and intra-arterial chemotherapy injection for case No. 11. An 11 year old, mixed-breed dog presented with hematuria and polyuria. The dog was diagnosed with transitional cell carcinoma of the lower urinary tract and treated with photodynamic therapy as in case No. 10 along with intra-arterial chemotherapy. An optical fiber placed in an 8Fr versatile catheter was inserted into the urethra (white arrow). The fiber tip was placed at the tumor site under ultrasound and the tumor was irradiated (150 mW, 270 J) under sedation.
