Surgery for overactive bladder
In this operation, a small piece of tissue from the intestine is added to the wall of the bladder to increase the size of the bladder. However, not all people can pass urine normally after this operation. You may need to learn to insert a catheter (a small tube) into your bladder in order to empty it.
This is a fairly large operation, but can provide very good improvements in symptoms in the right sorts of patients. It might be particularly useful in patients whose bladder is too small. Your specialist will advise you if this operation is appropriate for you.
Occasionally, this operation is combined with a Mitrofanoff procedure. The Mitrofanoff procedure creates a channel running between the bladder and the skin on the abdomen. The channel is made from a section of bowel or the appendix and allows the bladder to be drained by catheterisation. This procedure is done for those who need to empty their bladder by intermittent catheterisation but who cannot pass a catheter through their urethra.

In this operation, the ureters (the tubes from the kidneys to the bladder) are routed directly to the outside of your body. A section of the intestine is used to drain the urine into a bag worn on the tummy. This procedure is only done if all other options have failed to improve your overactive bladder and the symptoms are causing considerable distress.
