Urethral strictures are a condition where the urethra, the tube that carries urine from the bladder, narrows due to scarring, injury, or infection. This narrowing can lead to difficulty in urination, discomfort, and even severe urinary tract complications if left untreated. One of the most effective treatments for urethral stricture is the optical urethrotomy. This minimally invasive procedure provides relief by opening up the stricture and restoring normal urinary flow. In this comprehensive guide, we will explore everything you need to know about optical urethrotomy, including the causes of urethral strictures, how the procedure is performed, its advantages, risks, and post-operative care.

What Causes Urethral Strictures?
Urethral strictures can occur due to several factors. Here are some common causes:
- Trauma or Injury: Any injury to the pelvic area, particularly from accidents or surgical interventions, can lead to scarring in the urethra, causing a stricture.
- Infection: Sexually transmitted infections (STIs), especially gonorrhea or chlamydia, can damage the urethral lining, leading to narrowing over time.
- Prolonged Use of Catheters: Prolonged catheterization can cause friction and inflammation in the urethra, increasing the risk of scarring.
- Surgery: Urological surgeries, such as those for prostate issues or cancer treatments, can cause scar tissue formation.
- Congenital Conditions: In some cases, individuals are born with a narrow urethra, which can develop into a stricture over time.
Understanding the Optical Urethrotomy Procedure
Optical urethrotomy, also known as direct vision internal urethrotomy (DVIU), is a minimally invasive surgical technique used to treat urethral strictures. During this procedure, a surgeon uses a cystoscope (a thin, flexible tube with a camera) to visually guide the cutting of the scar tissue that is causing the narrowing in the urethra.
Step-by-Step Breakdown of the Procedure:
- Preparation: The patient is administered general or spinal anesthesia to ensure comfort and minimize pain during the procedure.
- Insertion of Cystoscope: The surgeon inserts a cystoscope through the urethra. This instrument allows the surgeon to have a clear view of the stricture and the surrounding tissue.
- Cutting the Stricture: A special knife or laser is used to make a precise incision in the scar tissue, opening up the stricture. This incision helps to restore the normal diameter of the urethra.
- Removal of Instruments: Once the incision is made, the cystoscope and other instruments are removed.
- Stenting (if necessary): In some cases, a temporary stent (a small tube) may be inserted to ensure the urethra stays open during the healing process.
Advantages of Optical Urethrotomy
Optical urethrotomy is preferred over more invasive surgical options because of several key advantages:
- Minimally Invasive: The procedure requires no external incisions, reducing recovery time and the risk of complications.
- Short Recovery Period: Most patients can resume normal activities within a few days of the procedure.
- High Success Rate for Short Strictures: The procedure is particularly effective for short-length strictures, providing long-term relief for many patients.
- Low Risk of Infection: Since the procedure is done through the urethra with no external cuts, the risk of post-operative infection is low compared to open surgery.
Who is an Ideal Candidate for Optical Urethrotomy?
Optical urethrotomy is typically recommended for patients with short urethral strictures (less than 2 cm in length) that are not accompanied by significant scarring or extensive tissue damage. Patients who have recurrent strictures or longer, more complex strictures may need additional treatments or alternative surgical options, such as urethroplasty.
Patients need to have a full evaluation by a urologist to determine if they are suitable candidates for this procedure. Imaging studies like a retrograde urethrogram or cystoscopy may be performed to assess the extent of the stricture before surgery.
Risks and Potential Complications
While optical urethrotomy is generally safe and effective, like any medical procedure, it comes with some risks. Some potential complications include:
- Recurrence of the Stricture: Urethral strictures can recur, particularly in patients with longer strictures or those who have undergone multiple urethrotomies.
- Bleeding: Mild bleeding during or after the procedure is common but usually resolves on its own.
- Infection: Although rare, there is a small risk of urinary tract infection after the procedure.
- Painful Urination: Some patients may experience discomfort or burning during urination for a few days following the procedure.
- Urinary Incontinence: In rare cases, patients may develop temporary or permanent urinary incontinence due to damage to the surrounding muscles.
Post-Operative Care and Recovery
Proper post-operative care is crucial for ensuring a smooth recovery and reducing the risk of complications. Here’s what to expect after an optical urethrotomy:
Immediate Aftercare:
- Hydration: It’s essential to drink plenty of water to flush out the urinary system and prevent infections.
- Medications: Patients are often prescribed antibiotics to prevent infections and pain relievers to manage discomfort.
- Catheter Care: If a catheter is placed post-operatively, it is essential to follow instructions for its care to avoid complications.
Long-Term Care:
- Follow-Up Appointments: Regular follow-up visits with the urologist are necessary to monitor the healing process and check for recurrence of the stricture.
- Avoid Heavy Activities: Patients should avoid heavy lifting and strenuous activities for a few weeks after the procedure to allow the urethra to heal properly.
- Monitoring Urinary Function: Any changes in urinary flow, pain, or recurrence of symptoms should be reported immediately to the healthcare provider.
