Urethral stricture causes include injury to the urethra, infections, inflammation, and scar tissue from previous surgery or catheter use. These factors narrow the urethra and block urine flow. Most strictures develop when scar tissue forms after trauma or repeated infection. This article explains the common and less obvious causes of urethral stricture, its warning signs, how doctors diagnose it, and the treatment options available at Lux Hospitals. Understanding what triggers this narrowing helps you seek timely care and protect your urinary health.
What Is Urethral Stricture?
A urethral stricture is a narrowing of the urethra, the tube that carries urine out of the body. Scar tissue forms and restricts normal urine flow.
It is far more common in men than women, due to their longer urethra. Left untreated, it can cause serious urinary problems.
Key facts to understand:
- Scar tissue narrows the urethra
- Blocks or slows urine flow
- Mostly affects men
- Can occur at any age
- May recur after treatment

1. Injury or Trauma to the Urethra
Physical injury is one of the most common urethral stricture causes. Trauma damages the delicate urethral lining, leading to scar formation.
Accidents affecting the pelvis or genitals often trigger this. The resulting urethral scar tissue narrows the passage over time.
Common injury sources include:
- Straddle injuries or falls
- Pelvic fractures from accidents
- Blows to the perineum
- Sports-related genital trauma
- Bicycle or motorcycle accidents
2. Infections and Sexually Transmitted Diseases
Infections are a leading cause of narrowing of the urethra. Repeated or untreated infections inflame and scar the urethral tissue.
Sexually transmitted infections are especially damaging when left untreated. A lingering urinary tract infection can also contribute.
Infections linked to strictures include:
- Gonorrhea and chlamydia
- Recurrent urinary tract infection
- Chronic urethritis
- Untreated STDs
- Bacterial inflammation of the urethra
Treat infections early—consult the specialists at Lux Hospitals to prevent complications.
3. Inflammation and Skin Conditions
Long-term inflammation can gradually scar the urethra even without injury. Certain skin conditions specifically affect the genital area.
Lichen sclerosus is a well-known inflammatory cause. Chronic irritation weakens and narrows the urethral wall.
Inflammatory causes may involve:
- Lichen sclerosus (BXO)
- Chronic genital skin irritation
- Long-standing urethritis
- Autoimmune inflammation
- Prolonged tissue swelling
4. Medical Procedures and Catheters
Medical instruments passed through the urethra can cause injury and scarring. This is a frequent, often overlooked cause.
Long-term catheter use is a major risk factor. Repeated insertions increase the chance of urethral damage.
Procedure-related causes include:
- Prolonged urinary catheter use
- Endoscopic surgery through the urethra
- Frequent bladder examinations
- Cystoscopy procedures
- Improper instrument insertion
5. Previous Surgery or Radiation
Surgeries involving the urethra or prostate can leave scar tissue behind. Radiation therapy for pelvic cancers may also damage the area.
These treatments can narrow the urethra months or years later. Careful monitoring after such procedures is important.
Surgical and radiation causes include:
- Prostate surgery complications
- Radiation for prostate cancer
- Hypospadias repair in childhood
- Previous stricture surgery
- Pelvic cancer treatment

Other and Unknown Causes
Not every urethral stricture has an obvious cause. Sometimes the reason remains unclear despite testing.
A few strictures are present from birth, while others link to underlying conditions.
- Congenital urethral abnormalities
- Idiopathic (unknown) strictures
- Tumors near the urethra
- Age-related tissue changes
Symptoms to Watch For
Symptoms often develop slowly as the urethra narrows. Many men ignore early warning signs.
Recognizing them early leads to faster treatment and fewer complications.
Common symptoms may include:
- Weak or split urine stream
- Difficulty urinating in men
- Straining to pass urine
- Frequent urinary infections
- Incomplete bladder emptying
- Pain during urination

How Urethral Stricture Is Diagnosed
Doctors use several tests to confirm a stricture and measure its severity. Diagnosis guides the right treatment choice.
A thorough evaluation identifies the location and length of the narrowing.
Common diagnostic tests include:
- Physical examination and history
- Uroflowmetry to measure flow
- Cystoscopy to view the urethra
- Retrograde urethrogram imaging
- Post-void residual urine test
Treatment Options at Lux Hospitals
Treatment depends on the stricture's length, location, and cause. Options range from minor procedures to reconstructive surgery.
Our urologists tailor each plan for lasting results and lower recurrence.
Available urethral stricture treatment options include:
- Dilation — gentle stretching of the urethra
- Internal urethrotomy — cutting the scar tissue
- Urethroplasty — reconstructive surgery
- Stent placement in select cases
- Ongoing follow-up to prevent recurrence
