There are many urinary disorders. Some are more common in men than in women, and vice versa. A urologist is expected to be able to identify these disorders and provide education regarding them.
"The most common cause of urinary hesitancy in older men is an enlarged prostate. Almost all older men have some trouble with dribbling, weak urine stream, and starting urination. Another common cause is infection of the prostate or urinary tract, which causes burning or pain with urination."
"BPH is a benign (noncancerous) enlargement of the prostate that blocks the flow of urine through the urethra. The prostate cells gradually multiply, creating an enlargement that puts pressure on the urethra. In men, urine flows from the bladder through the urethra. The pressure that is placed on the urethra due to BPH often causes urinary difficulty."
