Prostatomegaly is a medical condition in which the prostate gland is abnormally large. This is determined by rectal or abdominal palpation, or by abdominal X-ray or ultrasound imaging of the prostate. The enlargement can be symmetrical or asymmetrical, painful or nonpainful. Normal prostate size varies with age, body size, castration status, and breed, so determination of the enlargement is subjective.
Enlargement of the prostate gland can result from the proliferation or enlargement of epithelial cell (cells that line the cavities and surfaces of structures throughout the body); pre-cancerous cells in the prostate; or from inflammatory cell infiltration (e.g., acute and chronic bacterial prostatitis and prostatic abscess). Prostatomegaly is typically noted in middle-aged to older male dogs.
Since there are several possible causes for this condition, there also several different avenues your veterinarian can take in making the diagnosis. The diagnostic tools your veterinarian chooses will be based on the initial physical examination. Ultrasound is usually the tool of choice in determining whether the prostate is enlarged and whether there are cysts or abscesses on the prostate. A complete blood profile will be conducted, including a chemical blood profile, a complete blood count, and a urinalysis to determine whether an infection, bacterial or other, is involved. White blood cells in the urine, or in the seminal fluid, meanwhile, would indicate an infection of the bladder or urinary tract.
An examination of prostatic fluid obtained by ejaculation or prostatic massage may provide additional information about the state of the blood and whether an infection is present. Ultrasound will be used as a visual aid for guiding a fine-needle to the prostrate in order to draw fluid and/or cell tissue for biopsy. This process is referred to as fine needle aspiration.
