Urethral obstruction is another of those scenarios where ultrasound is under-used. Like azotaemic cats, I feel that they pretty much all benefit from being scanned. This is a recent patient, a male cat obviously, 24 hours after a difficult unblocking and who still has an indwelling urethral catheter. Several things to take from this: … Continue reading
It’s been a while since my erstwhile mentor Dr Bob O’Brien published this nice article: Vet Radiol Ultrasound Jul-Aug 1998;39(4):354-6Urinary bladder mural hemorrhage associated with systemic bleeding disorders in three dogsR T O’Brien, E F Wood https://pubmed.ncbi.nlm.nih.gov/9710141/ …and ultrasound technology has moved on a bit in the meantime. This is a recent case of the … Continue reading
There’s no point fighting against progress. Although this might reduce our sonography workload, I think it’s worth publicising this new urine test for canine bladder/urethra/prostate cancer (TCC or PC) because it looks like a real step forward. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0144170 There is a recent review of practical application of the test here: http://veterinarymedicine.dvm360.com/urine-luck-new-test-canine-bladder-and-prostate-cancer?pageID=2 … Continue reading
Transitional cell carcinomas are the commonest bladder neoplasm of dogs. However they only account for 70% of the total. Moreover, it’s important not to assume that all bladder tumours are TCCs since that may discourage partial cystectomy in situations where it may prove beneficial. This lesion in an 8 year old dog was found on … Continue reading
This is an ominous-looking bladder mass in a bitch: trigonal site, heterogeneous echogenicity and bladder wall invasion are all portents of potential malignancy. Athough a transitional carcinoma looks extremely likely, it would be good to have histological confirmation before making a definitive plan of action. The obvious issue is that percutaneous needle biopsy carries some … Continue reading
Now, this is a common problem. Dogs with dysuria and/or haematuria. You perform a full abdominal ultrasonogram and, behold! – an apparent soft tissue mass in the bladder. So, what is it? An FNA is generally regarded as being inadvisable since transitional cell carcinomas may seed along the needle line. Cystoscopy is certainly an option … Continue reading
