Alternative names: Bladder hypertrophy
An enlarged bladder is a condition in which the bladder becomes larger than normal, stretches too much, or develops thicker walls.
Some people are simply born with a larger-than-normal bladder. For other people, bladder enlargement is often caused by a blockage of the urinary tract, for example by bladder stones or a tumor. Other causes include abnormally high urine output volume, urine retention, or repeated failure to empty the bladder completely.
Surgery is generally used to remove the obstruction if that is the cause.
