Definition

The urethra is a tube that passes urine out of the body. Urethral dilation opens a narrow urethra.

Reasons for Procedure TOP

This procedure is done to allow urine to pass in people with:

Urethral stricture—scarring from swelling, harm, or infection
Meatal stenosis—a narrow opening of the urethra at the end of the penis

These problems are more common in men.

Possible Complications TOP

Problems are rare, but all procedures have some risk. Your doctor will go over some problems that could happen, such as:

Problems from anesthesia
Bleeding
Infection
Problems return and dilation needs to be repeated (common)
Harm to the urethra
Erection problems
Blood clots
Stroke
Heart attack

Smoking can make problems worse and slow healing. Quitting before surgery can improve recovery.

What to Expect TOP

Prior to Procedure

You will need to:

Arrange for a ride home.
Arrange for help at home while you heal.
Talk to your doctor about all medicines you are taking, including over the counter medicines and supplements. Some may need to be stopped up to 1 week before the dilation.
Avoid food or drink after midnight the night before surgery.

Anesthesia

You may be given anesthesia:

General—You will be asleep.
Local—The urethra will be numbed.

Description of the Procedure TOP

The urethra will be numbed. One of 2 methods will be used to widen the urethra:

A wire will be passed through the urethra. Plastic or metal rods will be passed over or next to the wire. They will stretch tissue in the narrow area.
A tube with a balloon will be placed in the urethra. It will be slowly inflated to stretch the area.

The tools will be removed. A tube may be placed to help urine pass while you heal.

How Long Will It Take? TOP

30 minutes

Will It Hurt? TOP

Anesthesia will prevent pain. There may be discomfort when tools are first put in. You may also have some discomfort when you pass urine in the next few days.

Post-procedure Care TOP

At the Care Center

You may be given pain medicine.

At Home

Most will return to normal activity by the next day.

Call Your Doctor TOP

Call your doctor if you are not getting better or you have:

More bleeding than expected
Signs of infection, such as fever and chills
Problems that return
Pain that you cannot control with medicine
Problems urinating
Nausea and vomiting
Problems having an erection
Chest pain

If you think you have an emergency, call for emergency medical services right away.
