Hi Tim & Kathy,
Thanks for your response. I live on the coast of Georgia. I inferred from your reply that you would have no qualms at all about having the biopsy performed? My vet recommended an oncologist in Jacksonville, Florida for the biopsy. (Jacksonville is about an hour away.) He has conferred with the oncologist by telephone about Brodie's case and has referred other patients to her in the past. The oncologist said debulking and chemotherapy could be performed but she also said patients with tumors in the trigone area generally don't survive a year even with that kind of extensive treatment. At the moment, Brodie is a very active and playful dog, but is unable to urinate freely and makes frequent trips outdoors.
In addition to the ultrasound, which has been performed twice, Brodie has had an x-ray, extensive urinalysis and blood work. He has taken two regimens of antibiotics, one for two weeks and one for six weeks. There are several abnormalities in both the urinalysis and blood work that would seem to point to cancer. My vet did not recommend doing the VBTA urine test due to the number of false-positives in cases where blood is present in the urine.
Thanks,
Jan
