BPH can be asymptomatic or symptomatic. Symptoms can be
related to the obstructive effect of prostate enlargement itself, to secondary
effects of the obstruction on the bladder, or to the complications of BPH.
Obstruction of the bladder outlet can have variable effects on the bladder.
It can lead to thickening of the bladder muscle and bladder muscle instability.
Bladder instability is thought to account for irritative symptoms.
Obstruction can also lead to, or worsen, poor bladder contraction. This can
lead to obstructive symptoms and poor bladder emptying. Both bladder
instability and poor bladder contraction are associated with aging per se.
Obstruction will accentuate both these effects of aging.
