Key Points

Document an unusual presentation of recurrent urethral obstruction and dysuria secondary to benign osseous proliferation of the os penis in a canine patient.
Evaluated a three-year-old male Pug presenting with chronic urolithiasis using biochemical profiling, ultrasonography, and retrograde urethrocystography.
Performed contrast-enhanced computed tomography to assess os penis morphology and urinary tract obstruction, followed by surgical excision and histopathological examination.
Computed tomography revealed a portosystemic shunt and abnormal osseous tissue proliferation of the os penis alongside ammonium urate uroliths.
Histopathological analysis confirmed non-neoplastic hyperplasia consisting of bland lamellar bone lacking cellular atypia or inflammation.
Surgical removal of the hyperplastic bone tissue successfully resolved the dysuria postoperatively.

Implication

Case report describes dysuria from non-neoplastic os penis bone hyperplasia in a dog, highlighting the value of computed tomography for evaluating recurrent urethral obstructions.

Abstract

A three-year-old male Pug presented with a three-year history of urolithiasis and repeated urethral obstruction. Biochemical analysis, ultrasonography, and retrograde urethrocystography revealed probable portosystemic shunt and incomplete urethral obstruction due to uric acid ammonium calculi. Enhanced computed tomography (CT) revealed portosystemic shunt and proliferation of the osseous tissue of the os penis, which was surgically removed. Histopathologically, the excised osseous tissue comprised bland lamellar bone without atypia or inflammation. Hyperplasia of the os penis was diagnosed based on the image findings and histopathology. The dysuria improved postoperatively. This is the first report of dysuria associated with non-neoplastic bone hyperplasia of the os penis in a dog. Careful evaluation of the os penis by CT is needed for accurate diagnosis in case of repeated penile urethral obstruction.
