Introduction
Visual Internal Urethrotomy (VIU) is a minimally invasive urological procedure used to treat urethral strictures, a condition in which the urethra becomes narrowed due to scar tissue. This narrowing can block or restrict the normal flow of urine, causing discomfort and urinary problems.
VIU surgery helps restore normal urine flow by making a small incision in the narrowed portion of the urethra. Understanding the procedure, possible risks, and recovery process can help patients make informed decisions and prepare for surgery with confidence.
What is Visual Internal Urethrotomy (VIU)?
Visual Internal Urethrotomy is a minimally invasive endoscopic surgery used to treat urethral strictures.
During the procedure, a surgeon inserts a thin instrument called a cystoscope or urethrotome through the urethra. This device contains a camera that allows the surgeon to clearly view the narrowed area. A small incision is then made in the scar tissue to widen the urethral passage and restore normal urine flow.
VIU is often recommended for patients with short urethral strictures and can help relieve symptoms without the need for major surgery.
Symptoms of Urethral Stricture
Urethral strictures can cause several urinary symptoms, including:
Weak urine stream
Pain or burning during urination
Difficulty starting urination
Frequent urinary tract infections (UTIs)
Blood in urine
Spraying urine stream
Feeling of incomplete bladder emptying
If these symptoms persist, medical evaluation is recommended.
When is VIU Surgery Recommended?
Your doctor may recommend VIU surgery if you experience:
Persistent difficulty passing urine
Repeated urinary tract infections
Reduced or obstructed urine flow
Diagnosed urethral narrowing that requires treatment
VIU offers an effective treatment option when conservative treatments do not provide relief.
Diagnostic Tests Before VIU Surgery
Before recommending VIU, your doctor may perform several tests to confirm the diagnosis and evaluate the severity of the stricture.
Common diagnostic tests include:
Physical Examination
Initial assessment to evaluate symptoms and medical history.
Imaging Tests (X-ray or Ultrasound)
These help determine the location and severity of the urethral narrowing.
Retrograde Urethrogram (RUG)
A specialized X-ray that uses contrast dye to visualize the urethra.
Urethroscopy or Cystoscopy
A small camera is inserted through the urethra to directly examine the urethra and bladder.
Post-Void Residual Test
Measures the amount of urine remaining in the bladder after urination.
Once a urethral stricture is confirmed, VIU may be recommended as a treatment option.
How VIU Surgery is Performed
1. Anesthesia
The procedure is performed under local, spinal, or general anesthesia to ensure the patient is comfortable and pain-free.
2. Insertion of Endoscope
A thin, flexible instrument with a camera (endoscope) is gently inserted through the urethra to access the narrowed area.
3. Identifying the Stricture
The surgeon carefully locates the exact position and extent of the urethral narrowing.
4. Incision of the Stricture
A small incision is made in the scar tissue to widen the urethra and improve urine flow.
5. Completion of the Procedure
After the narrowing is treated, a temporary catheter may be placed to help urine drain while the urethra heals.
Recovery After VIU Surgery
Immediate Recovery
After the procedure, patients may experience:
These symptoms usually improve within a few days.
Post-Procedure Care
To support healing, patients are advised to:
Follow-Up Visits
Follow-up appointments are important to ensure proper healing and monitor for recurrence of the stricture.
Possible Complications of VIU Surgery
Although VIU is generally safe, some complications may occur.
Common Complications
Rare but Serious Complications
Excessive bleeding
Urinary retention
Swelling of the penis
Severe infection
If symptoms such as high fever, severe pain, or heavy bleeding occur, medical attention should be sought immediately.
Success Rate of VIU Surgery
VIU surgery is most effective for short urethral strictures (less than 1.5 cm).
In cases of recurrence, additional treatments such as repeat VIU or urethroplasty surgery may be recommended.
Catheter Duration After VIU
After uncomplicated VIU surgery, a urinary catheter is usually placed temporarily and removed within 48 to 72 hours once healing begins.
Conclusion
Visual Internal Urethrotomy is a safe and minimally invasive treatment for urethral strictures that can significantly improve urinary symptoms and quality of life. However, understanding the procedure, potential risks, and recovery process is essential before undergoing surgery.
Discussing all available treatment options with your urologist will help you make the best decision for your individual condition and ensure the best possible outcome.
