Laser DVIU (Laser Direct Vision Internal Urethrotomy)
Laser DVIU is a minimally invasive endoscopic procedure used to treat urethral stricture disease, a condition where narrowing of the urethra restricts urine flow. Using advanced laser technology under direct vision, the stricture is precisely incised to restore normal urine passage. Laser DVIU offers improved accuracy, less bleeding, and faster recovery compared to conventional cold-knife DVIU. Direct vision internal urethrotomy (DVIU) is 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 Treatment Using Laser DVIU
Laser DVIU allows direct visualization of the urethral stricture using an endoscope. A laser fiber is used to carefully cut the narrowed segment, widening the urethral passage. This technique minimizes trauma to surrounding tissue, improves precision, and enhances postoperative comfort, making it a preferred option for selected urethral stricture cases.
How Laser DVIU Is Performed
Laser DVIU is carried out under anesthesia using endoscopic and laser technology.
Benefits of Laser DVIU
Laser DVIU provides effective relief from urethral stricture with minimal discomfort.
Description of the procedure
After you are asleep, a special tube called a cystoscope will be placed in your urethra to locate the stricture. Next, a special tool will be placed through the cystoscope and used to cut away the scar tissue inside your urethra to make it wider. The scar tissue may be removed by cutting or using a laser or heat source. After the tissue is removed, the urethra and bladder area will be examined. A catheter may be placed once the surgery is complete. A catheter is a plastic tube place through the urethra into the bladder.
DVIU
Direct vision internal urethrotomy (DVIU) is 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 or kidneys
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
Infection
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
Obesity
Smoking
Discuss these risks with your doctor before the procedure.
Success Rate of Laser DVIU
Laser DVIU has a good success rate in selected patients, particularly for short and simple urethral strictures. Regular follow-up is important to monitor for recurrence and maintain long-term results.
Preparation Before Laser DVIU
Before the procedure, patients undergo urine tests, imaging studies such as urethrogram, blood tests, and anesthesia assessment. Certain medications may need to be stopped to ensure procedural safety.
Life After Laser DVIU
After Laser DVIU, patients experience improved urine flow and symptom relief. Regular follow-up and, in some cases, urethral calibration help maintain long-term success.
