Prostatic mass with bilateral ureteral obstruction in a 12 year old MN Dachshund

Case Study

Prostatic mass with bilateral ureteral obstruction in a 12 year old MN Dachshund

The patient is a 12-year-old MN Dachshund, who was presented for dribbling urine. The dog was unwilling or unable o urinate on leash. A urinary catheter passed easily. The rectal exam was unremarkable.

Sonographic Differential Diagnosis

Prostatic mass with urethral involvement and obstruction. This is strongly suggestive of prostatic carcinoma. Secondary bilateral ureteral dilation. Mild hydronephrosis due to chronic increased urinary pressures.

Image Interpretation

The urinary bladder and trigone appeared normal. The right ureter was dilated and tortuous measuring 0.32 cm. The left ureter was also mildly dilated at 0.26 cm. The ureteral dilation is likely owing to stasis and urinary outflow issues due to urethral obstruction. No neoplastic invasion into the ureters was noted. The prostate was enlarged and hypoechoic with multi-focal, hyperechoic areas of mineralization and capsular expansion. The prostate measured 2.6 cm entering into the urethra and extended cranially to the cystourethral junction creating an obstructive pattern. The kidneys revealed minor degenerative changes and slight, dystrophic mineralization. Pyelectasia was noted in the right kidney at 1.0 cm and 1.33 cm in the left kidney. The left kidney was swollen at 4.8 cm. The right kidney measured approximately 4.5 cm. A hypogastric lymph node was enlarged, hypoechoic and irregular measuring 1.97 cm with other regional lymph nodes. These lymph nodes were also focally mineralized.

DX

Prostatic mass with bilateral ureteral obstruction

Outcome

None

Comments

Cox-2 inhibitor therapy may be added to the protocol +/- chemotherapy depending upon oncology consultation. However, urethral stent placement is strongly recommended.

Clinical Differential Diagnosis

Urinary incontinence, UTI, prostatic neoplasia, urinary neoplasia, urolithiasis.

Sampling

Ultrasound-guided FNA of the hypogastric lymph node and prostatic mass would be recommended, however, none was completed.
