Urine‐filled prostatic cavitary lesion as a cause of urinary incontinence in a juvenile male dog

Abstract

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.

Urinary incontinence in a male dog with an ectopic ureterocoele remnant associated with ipsilateral renal agenesis and cryptorchidism

“…5 Another case report describes a male dog with urinary incontinence and a prostatic utricle, with an improvement of their clinical signs achieved with both removal of the prostatic lesion and a prostatopexy performed. 20 It may have been beneficial in our case to have performed a procedure such as a prostatopexy alongside the surgical resection of the EUR to address the underlying USMI. 21 In summary, this is the first known case report describing ipsilateral EUR, RA and cryptorchidism in a male dog with urinary incontinence.…”

“…In a similar case report describing a male neutered dog with urinary incontinence with a left ectopic ureter and a right ectopic ureteral remnant, the dog's urinary incontinence resolved with surgical correction, performing a left neo‐ureterostomy and resecting the right ectopic ureter 5 . Another case report describes a male dog with urinary incontinence and a prostatic utricle, with an improvement of their clinical signs achieved with both removal of the prostatic lesion and a prostatopexy performed 20 . It may have been beneficial in our case to have performed a procedure such as a prostatopexy alongside the surgical resection of the EUR to address the underlying USMI 21 …”
