What Is a Urethral Stricture?

A urethral stricture is a narrowing of the urethra caused by scar tissue. The urethra is the tube that carries urine from the bladder out of the body. When scar tissue develops within the urethral wall, the urinary passage becomes narrower and urine may have difficulty passing normally.

Urethral strictures can occur at different locations and can vary in length, severity and complexity. Some strictures are short and may be treated with endoscopic procedures, while longer or recurrent strictures may require reconstructive surgery such as urethroplasty.

What Is Buccal Mucosal Graft Urethroplasty?

Buccal mucosal graft urethroplasty, commonly called BMG urethroplasty, is a reconstructive procedure in which tissue from the inner lining of the cheek is used to repair or augment a narrowed section of the urethra.

Buccal mucosa is suitable for selected urethral reconstruction because it is a durable mucosal tissue that can be harvested from the inner cheek. The graft is carefully removed, prepared and positioned at the site of the urethral narrowing.

The exact reconstructive technique depends on the location, length and severity of the stricture, the quality of the existing urethral tissue and any previous procedures.

When Is Buccal Mucosal Graft Urethroplasty Recommended?

Buccal mucosal graft urethroplasty is not required for every patient with urethral stricture. It may be considered when the characteristics of the narrowing make reconstructive surgery appropriate.

• Longer urethral strictures requiring reconstruction or augmentation.
• Recurrent urethral strictures after previous treatment.
• Selected complex urethral strictures.
• Strictures where repeated dilation or endoscopic treatment may not provide a durable result.
• Selected cases where the narrowed urethral segment requires additional tissue for reconstruction.
• Patients who require urethral reconstruction using a suitable graft material.

Risk Factors for Urethral Stricture

Certain previous medical conditions, procedures or injuries can increase the likelihood of developing scar tissue within the urethra.

• Previous urinary catheterization or instrumentation.
• Previous urethral or urological surgery.
• Trauma or injury involving the urethra or pelvis.
• Previous treatment for urethral stricture.
• Inflammation or infection affecting the urethra.
• Conditions associated with chronic urethral scarring.
• Repeated procedures involving a previously narrowed urethral segment.

Symptoms of Urethral Stricture

Symptoms may develop gradually as the urethral narrowing becomes more significant. Some patients may notice changes in their urinary stream while others may experience recurrent urinary problems.

Causes of Urethral Stricture

Urethral strictures can develop because of injury, instrumentation, inflammation or previous procedures. In some patients, the exact cause may not be clearly identified.

• Previous urinary catheterization or urethral instrumentation.
• Previous urethral or urological procedures.
• Trauma or injury to the urethra.
• Inflammation or infection affecting the urethra.
• Previous treatment for urethral stricture.
• Chronic conditions that can cause urethral scarring.
• Other causes of damage or scarring involving the urethral tissue.

Types of Urethral Strictures

Urethral strictures can be classified according to their location, length, severity and whether they have occurred again after previous treatment. These characteristics help the urologist plan appropriate treatment.

How Is Urethral Stricture Diagnosed?

Accurate assessment of the urethral stricture is important before planning reconstructive surgery. The urologist may recommend investigations based on urinary symptoms, medical history, previous procedures and examination.

• Detailed medical and urological history.
• Physical examination.
• Urine examination to identify infection or other abnormalities.
• Uroflowmetry to assess urinary flow.
• Post-void residual urine assessment when required.
• Retrograde urethrogram to assess the location and length of the stricture.
• Other imaging studies when clinically required.
• Urethroscopy or cystoscopy when appropriate.

When Should You Consult a Urologist?

Persistent changes in urinary flow should be evaluated, particularly when there is a history of previous urethral procedures, catheterization or urethral injury.

• Persistent weak or reduced urinary stream.
• Difficulty starting or maintaining urine flow.
• Repeated urinary infections or urinary discomfort.
• A feeling of incomplete bladder emptying.
• Previous treatment for urethral stricture with recurrent symptoms.
• Difficulty passing urine or episodes of urinary retention.
• Known urethral narrowing requiring further evaluation or treatment.

Treatment Options for Urethral Stricture

Treatment is individualized according to the location, length, severity and recurrence of the stricture. Previous procedures and the condition of the urethral tissue are also considered.

How Is Buccal Mucosal Graft Urethroplasty Performed?

The exact surgical technique depends on the location, length and extent of the urethral stricture. In general, the procedure involves preparing the narrowed urethral segment, harvesting buccal mucosa and using the graft to reconstruct or widen the urethral passage.

Preparation Before Buccal Mucosal Graft Urethroplasty

Appropriate preparation allows the surgical team to assess the urethral stricture, identify potential risks and plan the reconstructive procedure.

• Complete urological evaluation and review of previous treatments.
• Assessment of the urethral stricture using appropriate imaging or endoscopy.
• Urine testing to identify and treat urinary infection when required.
• Blood tests and other preoperative investigations as advised.
• Informing the doctor about current medicines and known allergies.
• Following instructions regarding blood-thinning medicines when applicable.
• Following fasting instructions before anesthesia.
• Informing the surgical team about relevant previous oral or dental procedures.

Recovery After Buccal Mucosal Graft Urethroplasty

Recovery varies between patients and depends on the extent of urethral reconstruction, individual healing and overall health. Both the urethral reconstruction and the cheek donor site require appropriate postoperative care.

Post-Treatment Care After BMG Urethroplasty

• Take prescribed medicines exactly as directed.
• Keep the urinary catheter clean and follow catheter-care instructions.
• Follow all instructions regarding catheter removal and follow-up imaging.
• Maintain appropriate hydration according to your doctor's advice.
• Follow recommended oral hygiene instructions for the cheek donor site.
• Follow dietary instructions provided during the early recovery period.
• Avoid strenuous physical activity until medically cleared.
• Attend all scheduled postoperative appointments.
• Report fever, significant bleeding, severe pain or difficulty passing urine promptly.

Diet and Lifestyle After Buccal Mucosal Graft Urethroplasty

Temporary changes in diet and daily activities may be recommended after surgery, particularly while the cheek donor site heals.

• Follow the diet recommended by the treating team during early recovery.
• Choose foods that are comfortable to chew while the cheek is healing.
• Maintain adequate fluid intake as advised by your doctor.
• Follow oral hygiene instructions carefully.
• Avoid activities that may interfere with surgical healing.
• Resume exercise and strenuous activities only after medical clearance.
• Attend follow-up appointments even if urinary symptoms have improved.

Advantages of Buccal Mucosal Graft Urethroplasty

Risks and Complications of BMG Urethroplasty

As with any surgical procedure, buccal mucosal graft urethroplasty carries potential risks. The likelihood of complications depends on the stricture, surgical technique and individual patient factors.

• Bleeding or infection.
• Temporary pain, swelling or numbness at the cheek donor site.
• Difficulty or discomfort while eating during early healing.
• Changes in sensation or tightness in the cheek.
• Urinary infection or other urinary complications.
• Urine leakage or complications involving the reconstructed urethra.
