Bladder augmentation is surgery to increase bladder size.

Bladder augmentation surgery makes the bladder large enough to collect urine. When the bladder is too small, urine can leak out of the body (incontinence) or back up into the kidneys (reflux). This can cause a kidney infection and could damage the kidneys. The procedure is used to treat serious forms of incontinence after other treatments have failed.

Birth defects and other conditions, like chronic obstructive bladder damage, can cause the bladder to be too small.

Surgery may also be done if you have:

  • An overactive bladder—bladder muscle contracts when it does not need to, leading to urine leakage
  • A neurogenic bladder—problems with nerve signals leading to the brain and muscles, leading to urine leakage or retention
