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
neurogenic bladder—problems with nerve signals leading to the brain and muscles, leading to urine leakage or retention
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like: Excess bleedingReaction to anesthesiaInfectionBlood clotsBladder ruptureAbdominal painUrinary incontinence—may be for a short time or require more surgery to fix

will be used. It will block pain and keep you asleep through the surgery.
The doctor will make an incision in the abdomen. An incision will also be made on the top part of the bladder. A part of the intestine or stomach will be removed and placed over the opening in the bladder. This new part will work like a patch. The doctor will sew it into place.
The doctor may also create a stoma. This is a small opening through the abdominal wall to an opening at the top of the bladder. This will make it easier for you to insert the catheter into the bladder.
A catheter will be left in place to drain urine from the bladder.
You may be given fluids, pain medications, and antibiotics through an IV. A tube will be placed through your nose to your stomach. This tube will keep your stomach drained of any contents. It will stay in place until your stomach and intestines begin working normally.
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
The usual stay is 6-10 days. If you have any problems, you will need to stay longer.
After your procedure, the hospital staff will: Give you fluids and nutrients through an IV—You will not be able to eat until your intestines are working normally. This may take several days.
