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. This narrowing is usually caused by scar tissue, which restricts urine flow and can lead to uncomfortable or serious urinary problems.
Urethral strictures are more common in men because the male urethra is longer, but they can also occur in women.
Symptoms
Symptoms may develop gradually and can range from mild to severe. Common signs include:
-
Weak urine stream
-
Difficulty starting urination
-
Spraying or split urine stream
-
Frequent urge to urinate
-
Pain or burning during urination
-
Incomplete bladder emptying
-
Urinary tract infections (UTIs)
-
Blood in urine
-
Swelling of the penis (in severe cases)
If left untreated, a urethral stricture can lead to bladder damage or kidney problems.
Causes
Urethral strictures are usually caused by injury, inflammation, or infection that leads to scar tissue formation. Common causes include:
1. Trauma or Injury
-
Pelvic injury (such as from accidents)
-
Injury from medical procedures (catheter insertion, surgery)
2. Infections
-
Sexually transmitted infections (STIs)
-
Repeated urinary tract infections
3. Previous Surgery
-
Prostate surgery
-
Bladder surgery
4. Radiation Therapy
Radiation treatment for prostate or pelvic cancers can damage the urethra.
5. Inflammatory Conditions
Certain inflammatory diseases can contribute to scarring.
Risk Factors
-
Male gender
-
History of catheter use
-
Prior urethral surgery
-
Pelvic trauma
-
Recurrent infections
Diagnosis
Doctors diagnose urethral strictures using several methods:
Physical Examination
Checking for swelling, tenderness, or signs of blockage.
Urine Tests
To detect infection or blood.
Imaging Tests
-
Ultrasound
-
Retrograde urethrogram (X-ray with contrast dye)
Cystoscopy
A thin camera is inserted into the urethra to examine the narrowing directly.
Treatment Options
Treatment depends on the severity and length of the stricture.
1. Dilation
The urethra is gradually stretched using special instruments. This may need to be repeated.
2. Internal Urethrotomy
A small incision is made to open the narrowed area using a scope.
3. Urethroplasty (Surgical Repair)
This is a more permanent solution where the scarred section is removed or reconstructed. It has the highest long-term success rate.
4. Catheter or Stent (In Some Cases)
Used temporarily to keep the urethra open.
Possible Complications
If untreated, urethral stricture can cause:
-
Recurrent urinary infections
-
Bladder stones
-
Urinary retention (inability to urinate)
-
Kidney damage
Early treatment helps prevent serious complications.
When to See a Doctor
Seek medical attention if you experience:
-
Difficulty urinating
-
Weak urine stream
-
Pain while urinating
-
Inability to pass urine (medical emergency)
Prevention
While not all strictures can be prevented, you can reduce risk by:
-
Practicing safe sex
-
Avoiding unnecessary catheter use
-
Treating urinary infections promptly
-
Protecting against pelvic injury
Final Thoughts
A urethral stricture is a treatable condition, but early diagnosis is important. If you notice changes in your urine flow or experience discomfort, consult a healthcare professional for evaluation and appropriate care.
