Urethral stricture is caused mainly by scarring from injury, infection, inflammation, or medical procedures that narrow the urethra and block urine flow. Trauma to the pelvis, sexually transmitted infections, and repeated catheter use are common triggers. This narrowing makes urination difficult and can lead to serious complications. In this article, we explain the top urethral stricture causes, key risk factors, warning symptoms, and how doctors diagnose and treat the condition. You will also learn when to consult a urology specialist for lasting relief.
What Is a Urethral Stricture?
A urethral stricture is a narrowing of the urethra, the tube that carries urine from the bladder out of the body. It usually results from scar tissue that restricts normal urine flow.
Strictures are far more common in men because their urethra is longer. When the passage narrows, urinating becomes slow and strained.
Key facts to understand:
- Scar tissue narrows the urethra
- More common in men
- Blocks or slows urine flow
- Can occur at any age
- Ranges from mild to severe

1. Injury and Pelvic Trauma
Physical injury is one of the most common urethral stricture causes. Damage to the pelvis or urethra creates scar tissue as it heals.
Accidents that fracture the pelvis often tear or crush the urethra.
Common injury sources include:
- Straddle injuries to the groin
- Pelvic fractures from accidents
- Falls onto hard objects
- Sports or bike injuries
- Direct blows to the perineum
2. Infections and STIs
Infections that inflame the urethra can leave scars behind. Repeated or untreated infections raise the risk of narrowing.
Sexually transmitted infections are a well-known trigger, especially when treatment is delayed.
Infections linked to strictures include:
- Gonorrhea and chlamydia
- Recurrent urinary tract infections
- Untreated urethritis
- Chronic bladder infections
- Inflammation from unresolved STIs
Treat urinary infections early—consult the specialists at Lux Hospitals to protect your urethra.
3. Medical Procedures and Catheters
Certain medical procedures can accidentally damage the urethra. This is a leading modern cause of narrowing of the urethra.
Instruments and tubes passed through the urethra may cause irritation and scarring.
Procedure-related causes include:
- Long-term catheter placement
- Repeated catheter insertions
- Endoscopy or cystoscopy
- Prostate or bladder surgery
- Radiation therapy to the pelvis
4. Inflammation and Skin Conditions
Chronic inflammation of the urethra can gradually create urethral scar tissue. Some skin conditions specifically affect the genital area.
One example is lichen sclerosus, which causes hardening and scarring of the tissue.
Inflammatory causes may include:
- Lichen sclerosus (BXO)
- Chronic urethral irritation
- Autoimmune inflammation
- Prolonged tissue swelling
- Recurrent skin lesions

5. Other and Less Common Causes
Some strictures develop from rare or unclear origins. In certain cases, no clear cause is ever found.
Congenital and tumor-related factors can also play a role.
Additional causes of urethral narrowing include:
- Congenital urethral defects
- Tumors near the urethra
- Previous urethral surgery
- Idiopathic (unknown) causes
- Cancer treatment side effects
Who Is at Risk?
Anyone can develop a stricture, but some people face higher risk. Understanding these factors helps with early detection.
Men with a history of trauma or infection are especially vulnerable.
Higher-risk groups include:
- Men more than women
- History of STIs
- Frequent catheter users
- Prior pelvic surgery
- Enlarged prostate patients
- People with pelvic injuries
Warning Symptoms to Watch
Urethral stricture symptoms often start mild and worsen over time. Difficulty urinating is usually the first sign.
Many men ignore early changes until flow becomes severely blocked.
You may notice:
- Weak or split urine stream
- Straining to urinate
- Incomplete bladder emptying
- Frequent or urgent urination
- Pain or burning while urinating
- Blood in the urine
Don't ignore urinary flow problems—schedule an evaluation at Lux Hospitals now.
Possible Complications
Untreated strictures can lead to serious problems. Blocked urine flow strains the whole urinary system.
Early treatment prevents long-term damage to the bladder and kidneys.
Complications may include:
- Recurrent urinary infections
- Bladder stones
- Urinary retention
- Kidney damage
- Painful swelling or abscess
How Urethral Stricture Is Diagnosed
Diagnosis begins with a review of symptoms and medical history. Doctors then use imaging and tests to confirm the narrowing.
These tests locate the stricture and measure its severity.
Common diagnostic methods include:
- Uroflowmetry (flow measurement)
- Cystoscopy of the urethra
- Retrograde urethrogram imaging
- Urine tests for infection
- Ultrasound of the urinary tract
