Case Study

Urethral mass in a 11 year old S Dachshund dog

An 11-year-old SF Dachshund with a history of recurrent UTI was presented for evaluation of chronic, inappropriate urination and more recently pollakiuria. Urinalysis showed isosthenuria and hematuria. Abnormalities on serum biochemistry were mildly elevated ALP and AST activity, 95, CPK 1944, albumin 4.1, total protein 7.9.

Sonographic Differential Diagnosis

Mineralizing urethral mass. This is strongly consistent with transitional cell carcinoma.

Image Interpretation

The urinary bladder in this patient presented mineralizing urethral mass that measured at least 2.5 cm into the pelvic urethra caudal from the cystourethral junction. Significant power Doppler signal noted. Small calculus was noted in the bladder and measured 0.2 cm. The apex and body of the bladder appeared unremarkable.

DX

Urethral mass

Outcome

None

Comments

Ultrasound-guided laser ablation is recommended in this patient +/- eventual stent placement. Traumatic catheterization can also be considered for a definitive diagnosis.

Clinical Differential Diagnosis

Bladder pathology– urolith, neoplasia, chronic bacterial cystitis, polyploid cystitis
