A normal prostate gland is about 3-4cm long and about 3-5cm in width, so this one sounds about the right size. The parenchyma is the tissue that makes up the gland, and it is also pretty normal, since the echoes are all uniform. That means there are not spots where the ultrasound shows it to be thicker or thinner than it should be. The bladder was was physiologically distended, meaning it was enlarged due to it's normal function- it was holding urine. A post void scan is done after the man empties his bladder, and in this case, there was approximately 30 mil of urine that did not empty. That's no so unusual, and anything under 50 ml doesn't raise any eyebrows. In men over the age of around 60 or so you can see anywhere between 50 and 100ml of urine retained. It's a common side effect of a gentleman with benign prostatic hypertrophy. In this case though, it doesn't look like they found anything that is disturbing or abnormal.The normal prostate size for an adult male is 15cc to 30cc (one half ounce to one ounce). Men whose prostate gland is larger than 30 cc are more likely to be diagnosed with either benign hyperplasia (enlargement) or prostate cancer than those whose prostate is in the normal range.
