COMMON BLADDER DISORDERSKRISTIN LORIA
HISTORY Signalment – 4 year old female spayed Hound Presenting Complaint – Inappropriate
Urination Lab findings – None she just walked in your
door Possible Tests to rule out Ddx – Blood work
(CBC, Chem), urinalysis, urine culture, radiographs, Ultrasound
U/S Ddx – Calculi, tumors, cystitis(possible UTI)
CALCULI Radiopaque or radiolucent calculi are
seen as hyperechoic focal echogenicities that shadow in the dependent portion of the bladder
Are usually located in the dependent portion of the bladder but may adhere to the wall with severe inflammation
MILD CALCULI
MODERATE
SEVERE CALCULI
SEDIMENT Suspended with bladder agitation
CYSTITIS Typically Cranioventral Can be generalized if severe If the bladder is not fully distended the
wall may appear thicker
FOCAL CYSTITIS
CYSTITIS
EMPHYSEMATOUS CYSTITIS
EMPHYSEMATOUS CYSTITIS Infection with E. Coli Infection with Clostidium species Diabetes Mellitus The gas bubbles will follow the wall
contour Can be confirmed by radiographs –
lucencies associated with the bladder
POLYPOID, CYSTIC PROTRUSION
POLYPS Polyps are rare Must be confirmed by biopsy Neoplasia more common
TRANSITIONAL CELL CARCINOMA
Trigone and Urethra
TRANSITIONAL CELL CARCINOMA
TRANSITIONAL CELL CARCINOMA Most common bladder tumor in dogs Focal wall thickening, could have
generalized thickness (diffuse tumor) Fixed mass extending into the lumen of
the bladder U/S guided catheter biopsy – lesion
pushed to catheter by transducer pressure or cystoscopy
Check iliac LN and thoracic rads
KEEP IN MIND To differential Ddx – remember moving
objects will settle to the dependent part of the bladder.
Dorsal in down, ventral is up. Sampling for TCC - No aspirates Inappropriate urination could be
behavioral, pollakiuria, PU/PD, stranguria (ask more questions to clarify)
