What are the treatments for an enlarged bladder?

The bladder holds between 10 and 14 ounces of urine comfortably in most adults. Urine is produced constantly by the kidneys and then flows into the bladder for storage. The urine is held in the bladder by a valve-like muscle called the sphincter, which is located at the base of the bladder.

When the bladder becomes full, a reflex reaction occurs to empty the bladder. The sphincter muscle relaxes to open the bladder outlet and the bladder wall contracts to squeeze out the urine. In infants, this reflex occurs automatically. After toilet training, we are able to control the reflex so the bladder empties only when we "give it permission."

If the bladder does not empty fully, urine may build up and cause the bladder to become enlarged. The distended bladder may leak, a condition called overflow incontinence.

The treatment depends on the cause, which generally fall into two categories:
  • blockage of the bladder outlet
  • failure of the bladder to contract enough to push out the urine
The treatment options depend upon the underlying cause of your large bladder. For example, a blockage may require a surgical procedure to open it. Other causes of a large bladder might be treated with medication.
