Case Study

06_00303 Oz B Urethral calculus

A 10-year-old NM Chihuahua was presented for evaluation of urine dribbling and stranguria. A cystotomy had been done 2 months prior with no postoperative radiographs taken.

 

Sonographic Differential Diagnosis

Distal urethral calculus. Polypoid cystourethral junction calculi. Other small calculi were also noted in the urethra. Surgical consultation is recommended for perineal urethrostomy and retropulsion or retraction of the calculus is recommended. However, concurrent cystotomy is likely necessary with biopsies of the polyps at the cystourethral junction. The polypoid changes at the trigone are likely hyperplastic owing to passage of calculi. However, underlying TCC could not be ruled out. Sampling through ultrasound-guided traumatic catheterization could be performed during surgery. It would be difficult to retropulse this urethral calculus.

Image Interpretation

The urinary bladder presented significant polypoid changes throughout the dorsal wall and trigonal area. The deep pelvic urethra in this patient revealed a 1.19 cm embedded calculus at the distal aspect of the urethra. Imaging was performed from the perineal region.
