What Happens during Bladder Augmentation?

Before bladder augmentation surgery, tests are done to measure bladder and kidney function and structure. These tests may include blood tests , x-rays , and bladder pressure studies (urodynamics). The same tests may be done after surgery to make sure the bladder is healing.

During surgery, a section of the bowel or stomach is used to make the bladder larger. The surgeon makes a cut in the belly and opens the top of the bladder. A section of the bowel or stomach is cut out and sewn onto the top of the bladder as a patch.
