What is BPH?
Benign Prostatic Hyperplasia (BPH) is the most common prostatic disease that occurs in intact male dogs. It is an enlargement of the prostate which in most cases has no clinical issues.
In most cases unlike the human equivalent, where 50% of men over 60 experience urinary problems associated with BPH (Ling, 1995), male dogs rarely have any clinical signs. In acute cases, signs include tenesmus, haemuria and spermhaematic , constipation and straining to urinate
BPH is palpable in during rectal examination and the enlargement varies dependent severity.
On ultrasound BPH can be seen as slightly more echogenicity than a normal prostate with 1-2mm anechoic cysts and in cases of more clinical BPH cysts can be as large as 2-3cm in diameter.
Benign Prostatic Hyperplasia is common intact male dogs; 16% of dogs aged 2years, 50%by 4-5years and 95% by 9years of age. There is no breed predisposition associated with BPH although Scottish Terriers have a prostate 4 times the size of dogs a similar weight.
