(Urinary Diversion Surgery)
Deanna M. Neff, MPH
An ostomy makes an opening in the belly wall. A urostomy allows urine to pass to a bag outside of the body. An internal pouch can also be created using the intestine.
Once healed, a urostomy shouldn’t limit your activities.

Reasons for Procedure TOP
A urostomy is needed if urine can’t pass through the urinary system as normal. You may need one because of:
- Structural defects—some may have existed since birth
- Long term inflammation
- Nerve or muscle problems
Possible Complications TOP
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review possible problems such as:
- Irritated skin
- Fluid buildup in the belly
- Blocked urine flow
- Organ damage
- Blood clots
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of problems such as:
What to Expect TOP
Prior to Procedure
Your doctor may do:
- A physical exam
- Urine tests
- Blood tests
You may also need to:

- Arrange for a ride home.
- Arrange for help at home.
- Not eat or drink the night before your surgery.
Description of the Procedure TOP
An incision is made in the belly to access the area. There are several ways to create a new path for the urine to flow. Your doctor will discuss the options with you.
Most methods require a stoma. A stoma is an opening made through the belly wall. A small section of small or large intestine will be removed. It will be used to make a path between the ureters and the stoma. Ureters are tubes that carry urine from the kidneys to the bladder. There are 2 main types:
- Conventional—The intestine is shaped like a tube. It allows urine to flow freely from the stoma into an external bag.
- Continent—The intestine is shaped like a pouch. This will let you store the urine in your body until you drain it with a special tube called a catheter.
A third type, called a neobladder, doesn’t need a stoma. A pouch is made from the small intestine. The ureters and urethra (the tube that carries urine out of the body) are connected to it much like the original bladder. Urine can then pass from the body like it did with the bladder.
The incisions are closed with stitches and bandaged.
