A two-year-old, entire male Welsh springer spaniel presented for investigation of urinary incontinence, present from a young age. Contrast-enhanced abdominal computed tomography (CT)revealed a large, fluid-filled lesion within the prostate gland. A retrograde urethrocystogram documented leakage of contrast medium from the urethra into the lesion. Surgery revealed a prostatic cavitary lesion communicating directly with the prostatic urethra via multiple urethral defects, allowing accumulation of urine within the lesion. Partial prostatic wall resection and intracapsular prostatic omentalisation were performed after debridement and closure of the urethral defects. Prostatopexy was performed to maintain an intra-abdominal bladder neck and address the possibility of concurrent urethral sphincter mechanism incompetence. Histological examination of prostatic wall biopsies revealed bacterial prostatitis and culture yielded Staphylococcus aureus. The urinary incontinence resolved completely postoperatively. A urine-filled prostatic cavitary lesion, with concurrent prostatic urethral defects, should be included in the differentials of urinary incontinence in young male dogs.
