Interstitial cystitis versus lymphoma-neoplasia

I would appreciate your help with this bladder.

-14 year old, FS, mongrel dog, with very chronic history of UTI for years.

-Recently, the UTI seems to return very often. I scanned her few months back and suspected interstitial cystitis + secondary infection. Antibiotic therapy has been given based on cultures from mid-stream voided urine as owner is very concerned about anything invasive, even cystosample. However, We persuaded her to do a cysto saple today because we feel stuck at interpreting culture results accurately.

However, We persuaded her to do a cysto saple today because we feel stuck at interpreting culture results accurately.

-When I saw the bladder, I decided against cystosample based on the possibility of potential underlying neoplasia (lymphoma more than TCC, right?). I still see some layering but not all the tie and the vascular pattern concernes me; it is so thick and the dog had just emptied the bladder so there is little urine for a more extended wall. I suspect there is a chronic interstitial cystitis and my fear is that after so many years there is now neoplasia…(is this a logical thinking?).

Rest of abdominal scan: liver some poorly defined hypoechoic lesions, DDx nodular hyperplasia, any other neoplasia, Spleen is similar and only there appears to be a hypoechoic nodule/cystic formation in pancreatic area. Bloodwork is all WNL.

Questions, do you agree taking a cysto is risky if neoplasia??

I strongly suggested full thickness biopsy or at least, cystoscopy for mucosal sample (for culture for treating the bacteria accordingly if any and histopath, in case we are lucky and get a diagnosis from it).

Owner is very reluctant to do anything invasive but loves this dog. What do you think of the wall and what would you do? in the end, we still do not have a sterile collected urine sample for culture and dog is been placed on high dose baytril at night for 3-5 days and cerenia, and after baytril we were considering pyroxicam, but…what is your input?

Thank you very much.

Sorry, forgot to mention that

Sorry, forgot to mention that in December, we did a cytology from voided urine and no signs of neoplastic cells were seen, as well as the wall was definitely not as thick! it was only 0.6cm (although, back then there was more urine in the bladder).Also, the most recent cultures have shown different bacteria including E.coli and MRSA…after abs treatment …other bacteria grew…so we really dont trust the result because they were not cystosampled.

Thanks

OK- Ill give my

OK- Ill give my opinion.

Chronic polypoid cystitis. Can’t RI/RO neoplasia.

I would have no problem doing a cysto and get a good UA/Culture.

This is a chronic bladder and will have to be treated aggressively.

Thank you Randy, much
Thank you Randy, much appreciated.

Agree with Randy – chronic

Agree with Randy – chronic bladder pathology that needs aggressive therapy. Intersititial cystitis mainly a feline disease and never seen the bladder becoming that thick. Would try FNA and even a catheter assisted biopsy for HP and culture.

Thank you, but I’m still
Thank you, but I’m still confused about FNA…you mention you’ve never seen such a thick wall…that interstitial cystitis is uncommon in dogs… and that neoplasia can still exist…so…why would we still do FNA…if it is lymphoma, not too bad because it is not reported to seed…but if there is TCC wouldn’t it be contraindicated?
I’m any case, good to know that it doesn’t look malignant. Next time I’ll do cystosampke then..
Thank you for the input.

Meant that never seen

Meant that never seen interstitial cystitis resulting in that degree of thickness. In this case, for adequate management you need a diagnosis. There is much debate as to seeding from a TCC via an FNA

Thank you, I admit I became a
Thank you, I admit I became a bit chicken with bladder because I had a bad experience of having sampled a bladder that could potentially be TBC and even though the issue of seeding was raised the sample was inconclusive and the owner was very upset because “it shouldn’t have been done”. So after that…im very cautious, may be too much.
In this case…i think you are right we need a diagnosis…just wondering whether full thickness biopsy would be better .
Thanks for the input. Very hrlpful

Full thickness always better

Full thickness always better as can a larger sample with all layers of the wall. Also allows to biopsy from macroscopic pathological areas.

Bladder LSA is extremely rare

Bladder LSA is extremely rare in dogs and TCC tends to have a different more polypoid distribution just search transitional cell carcinoma in the archive and you will see what I mean. if this dog has chronic recurrent uti, or recessed vulva and such a hx then likely really bad cystitis but traum cath here if you can catheterize a female… culture and cyto. This si safe no matter what the pathology
