Direct vision internal urethrotomy (DVIU) is a surgery to repair a narrowed section of the urethra. This is referred to as a stricture. The urethra is the tube through which urine passes from the bladder to the outside of the body.
Urethral stricture is due to scarring of the urethra. This scarring may be caused by infection or injury. DVIU cuts through the scar tissue and opens the urethra.

Urethral stricture can result in:
- Prostate problems in men
Infections of the
bladder, ureters, which are tubes that carry urine from the kidneys to bladder, or
- Inability to urinate or empty the bladder completely
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Reaction to anesthesia
- Excessive bleeding
- Blood clots
- Pain when urinating
- Damage to urethra
- Recurrent stricture
- Need for more procedures
- Penis pain
- Erectile dysfunction
Factors that may increase the risk of complications include:
- Bleeding disorders or taking medications that reduce blood clotting
Discuss these risks with your doctor before the procedure.
Your doctor may do the following:
- Conduct a physical exam and ask about your medical history
- Order imaging, blood, and urine tests
- Talk about the anesthesia being used and its potential risks
Talk to your doctor about your medications. You may be asked to stop taking some medications up to ten days before the procedure, including:
- Aspirin or other nonsteroidal anti-inflammatory drugs, such as ibuprofen or naproxen
- Blood thinners, such as warfarin
- Anti-platelets, such as clopidogrel
In the days leading up to the procedure:
- Take a shower before the procedure as directed.
- Arrange for a ride home from the hospital.
- Do not take anything by mouth starting eight hours before your procedure. Ask the doctor how you should take your regular medications on the morning of your procedure.
anesthesia will be used. It will block any pain and keep you asleep or sedated through the surgery.
After you are asleep, a special tube called a cystoscope will be placed in your urethra to locate the stricture. Next, the doctor will place the DVIU scope into your urethra. A special tool will be used to cut away the scar tissue inside your urethra to make it wider. The doctor may remove the scar tissue by cutting or using a laser or heat source. After the tissue is removed, the doctor will examine the urethra and bladder area.
Anesthesia prevents pain during surgery. Ask your doctor about medication to help with the pain.
You will be able to go home the same day in most cases.
- You will be monitored while you recover from the anesthesia.
- The nurses will help you eat and move around again.
- You will be given pain medication.
- A catheter will be placed temporarily after the procedure. A catheter is a tube placed through the urethra to the bladder to empty it.
When you return home, do the following to help ensure a smooth recovery:
- Take medications as directed for pain. You may feel pain for up to two weeks.
- Care for your catheter as directed. The catheter may need to remain in place from a few days to two weeks. Your doctor may ask you to insert a catheter a few times a week to keep the scar tissue from closing again.
- Avoid lifting heavy objects for two weeks.
- Drink plenty of fluids.
- Do not drive or have sex until your doctor says it is okay.
- Ask your doctor when you can return to work. You may be able to go back to work in a few days.
- Take a shower instead of a bath until the catheter is removed.
- Follow all your doctor's instructions.
Call your doctor if any of the following occurs:
- Increasing pressure or pain
- Catheter does not drain properly
- Difficulty passing urine after catheter is taken out
- Changes in frequency or volume of urine
- Signs of infection, including fever or chills
- Excess blood in urine
If you think you have an emergency, call for medical help right away.
