Urethral strictures are a common and treatable cause of slow, difficult, or painful urination. They occur when part of the urethra (the tube that carries urine out of the body) becomes narrowed due to scarring. The aim of treatment is to restore a reliable urine flow, reduce the risk of infections and bladder problems, and protect long-term urinary and kidney health.

Understanding a urethral stricture

A urethral stricture is a narrowing of the urethra caused by fibrosis (scar tissue) after the lining of the urethra has been injured or inflamed. In men, the urethra is longer and passes through spongy tissue (corpus spongiosum). Injury to this area can lead to scarring and tightening that may worsen over time.

A stricture can be short and limited to a small segment, or longer and more complex. The length and location of the narrowing strongly influence which treatment is most appropriate and how durable the result is likely to be.

Why strictures happen

A stricture usually develops after damage to the urethra. Common causes include:

• Previous urology procedures or surgery involving the urethra or prostate (for example, operations performed through the urethra)
• Urinary catheter use, particularly if insertion was difficult or prolonged
• Urethritis, including inflammation related to sexually transmitted infections
• Trauma to the perineum (the area between the genitals and anus), such as a straddle injury
• Passing a stone that injures the urethra

In some people, no clear trigger is identified, but scarring still develops.

Symptoms that may suggest a stricture

Symptoms can range from mild to severe, and they often progress gradually. Typical features include:

• Reduced urine flow or a weak stream
• Needing to strain to pass urine
• A split or “forked” stream
• Dribbling after urination
• Taking longer to empty the bladder
• A feeling of incomplete emptying

With more advanced narrowing, urination may become extremely difficult, with only drops passing, or urine may stop altogether (urinary retention), which needs urgent medical attention.

Because urine flow is obstructed, strictures can also contribute to:

• Recurrent urinary tract infections
• Burning or discomfort when passing urine
• Bladder stones
• Lower abdominal pain or pressure

Why assessment matters

A careful assessment is important because not all urinary symptoms are caused by a stricture. Conditions such as an enlarged prostate, bladder overactivity, urinary infection, or neurological bladder problems can cause similar symptoms.

At our urology clinic, evaluation is focused on confirming whether a stricture is present, mapping its exact position and length, and identifying factors that may affect treatment choice, including previous procedures and any prior stricture treatments.

Tests commonly used

Investigations are selected based on symptoms and clinical findings. They may include:

• Medical history and examination: often the most informative first step
• Uroflowmetry (uroflow test): measures the speed and pattern of urine flow and can indicate obstruction
• Imaging of the urethra with contrast X-ray: specialised studies may be used to define the narrowing and its length
• Cystoscopy: a thin camera is passed into the urethra to directly visualise the narrowing; this can help with both planning and, in selected cases, treatment

Will a stricture improve without treatment?

A urethral stricture is a physical narrowing due to scar tissue. It does not reliably resolve on its own, and medication cannot remove the scar. While antibiotics may treat an infection that occurs alongside a stricture, they do not treat the underlying blockage.

Because the narrowing can worsen and lead to complications, timely specialist assessment is recommended.

Treatment options and how they work

The most suitable approach depends on:

• Stricture length and location
• Degree of narrowing and whether it is partial or complete
• Cause of the stricture
• Whether this is a first-time stricture or a recurrence
• Previous procedures (for example, prior endoscopic treatments)

Broadly, treatment falls into two categories: endoscopic (minimally invasive) procedures and open reconstructive surgery (urethroplasty).

Endoscopic procedures (minimally invasive)

Endoscopic treatment is performed through the urethra without external incisions. Options may include:

• Dilation: the narrowed segment is gently stretched
• Internal urethrotomy: the stricture is cut internally using a small blade or laser to widen the channel

These approaches are typically considered when the stricture is short and uncomplicated. They can improve urine flow quickly, but recurrence is common, especially as stricture length increases.

A key limitation is durability. Some people experience repeated narrowing and may require repeat procedures. If endoscopic treatment fails or the stricture returns quickly, repeating the same approach multiple times may reduce quality of life and can make later reconstruction more complex. In such situations, open reconstructive surgery is often discussed.

Temporary urinary diversion when urine cannot pass

If the urethra is completely blocked and urine cannot be passed, urgent drainage is needed. In some cases, a suprapubic catheter (a catheter placed through the lower abdomen into the bladder) is used to relieve retention and protect the kidneys while definitive treatment is planned.

Urethroplasty (open reconstructive surgery)

Urethroplasty is an operation that repairs the narrowed section of the urethra. It is generally considered the most durable option for longer strictures, recurrent strictures, or strictures that have not responded to endoscopic procedures.

There are different urethroplasty techniques. Depending on the location and length, the narrowed segment may be removed and the healthy ends rejoined, or the repair may be augmented using tissue grafts. The specific method is determined after imaging and cystoscopic assessment.

Because urethroplasty is more involved than endoscopic treatment, planning and follow-up are especially important. The goal is a stable, long-term improvement in urine flow and a lower risk of repeated procedures.

Regenerative or adjunct treatments

In selected settings, injection-based adjuncts have been explored to support tissue healing after endoscopic treatment. The suitability and expected benefit can vary, and the evidence base and availability differ between centres. If such options are relevant, they can be discussed in the context of stricture type, prior recurrence, and overall treatment goals.

Recovery and what to expect afterwards

Recovery depends on the procedure performed.

After endoscopic treatment

Many patients return to normal daily activities relatively quickly. A temporary catheter may be required for a short period. Follow-up typically includes symptom review and, where appropriate, repeat uroflow testing to monitor for recurrence.

After urethroplasty

Recovery is longer and often involves:

• A catheter for a defined period to allow the repair to heal
• A planned follow-up schedule, which may include imaging or cystoscopy in selected cases
• Gradual return to full activity based on the surgeon’s advice

It is normal for the care team to monitor urine flow and urinary symptoms over time, as early identification of recurrence improves management options.

Risks, limitations, and important considerations

All procedures carry risks, which vary depending on the technique and individual health factors. Your specialist will explain the risks most relevant to you, but key considerations include:

• Recurrence: more common after dilation or internal urethrotomy, particularly for longer strictures
• Infection: urinary infection can occur around the time of procedures and is typically treatable
• Bleeding or temporary discomfort with urination
• Urinary retention: occasionally urine flow may not improve immediately or may worsen due to swelling
• Need for further procedures: especially if the stricture returns

Leaving a significant stricture untreated can lead to repeated infections, bladder stones, and back-pressure on the urinary tract. In severe cases, prolonged obstruction can affect kidney function. Infection can also spread to nearby structures, contributing to inflammation of the prostate or testicles.

Your consultation and ongoing support

Care for urethral strictures benefits from continuity and experienced decision-making. At our urology clinic, the consultation focuses on:

• Understanding your symptoms and how they affect daily life
• Reviewing prior catheter use, infections, sexually transmitted infections, trauma, and any previous urology procedures
• Confirming the diagnosis with appropriate tests
• Explaining the likely cause, the stricture’s characteristics, and which options are most suitable
• Setting realistic expectations about success rates, recurrence risk, and follow-up

After treatment, our medical team provides structured follow-up to monitor recovery, manage catheter care when needed, and respond promptly if symptoms return. If you develop inability to pass urine, fever, severe pain, or worsening urinary symptoms at any stage, urgent assessment is advised.
