Prostatic Diseases in Small Animals

Prostatic diseases in small animals include benign prostatic hyperplasia, bacterial prostatitis (acute and chronic), prostatic cysts and abscesses, and prostatic metaplasia and neoplasia. Disease of the prostate can be inapparent or cause urinary, GI, and musculoskeletal signs. Evaluation of prostatic fluid, as well as ultrasonographic size and echotexture of the prostate, will yield a ...

Prostatitis (inflammation of the prostate gland) is the second most common prostatic disease of sexually intact male dogs. In neutered dogs, prostatitis is uncommon. Prostatitis in dogs can be either acute or chronic (with the latter being the more common form).
Paraprostatic Cysts in Dogs

Paraprostatic cysts are found adjacent to the prostate gland and result from embryological remnants of the female reproductive tract, found in males, which become fluid-filled. Clinical signs of paraprostatic cysts become apparent only when the cyst reaches a size sufficient to cause pressure on adjacent organs (eg, bladder, colon).
Benign prostatic hyperplasia is the most common prostatic disorder in sexually intact male dogs and results from androgenic stimulation or an altered androgen:estrogen ratio. Clinical signs may be absent, but persistent or intermittent hematuria, hemospermia, and/or hemorrhagic preputial discharge are most commonly reported.

Paraprostatic Cysts in Dogs
Paraprostatic cysts are found adjacent to the prostate gland and result from embryological remnants of the female reproductive tract, found in males, which become fluid-filled. Clinical signs of paraprostatic cysts become apparent only when the cyst reaches a size sufficient to cause pressure on adjacent organs (eg, bladder, colon).
Reproductive system diseases occur in both sexually intact (unneutered) and neutered male dogs and cats. Affected organs can include the urethra, testes (whether normally descended into the scrotum or undescended [cryptorchidism]), penis, and prepuce; disease can also extend to other parts of the genitourinary system , such as the prostate gland ...

Abstract Benign prostatic hyperplasia (BPH) is a common condition in intact male dogs and a leading cause of subfertility. While surgical and chemical castration are effective treatments for BPH, managing this condition in breeding dogs is challenging due to the desire to preserve reproductive function.

The clinical signs in dogs with prostate disease include haematuria, dysuria, urinary incontinence, dyschezia, pain and weight loss. These signs are not pathognomonic and so must be differentiated from similar signs due to non- prostatic disorders.
