The urethra is the passage through which urine is transported from the bladder to the outside of the body. Urethral stricture occurs when this passage narrows, usually due to scarring or other damage. This narrowing can impede normal urine flow, leading to problems such as painful urination, a severely reduced urine stream, and, in severe cases, a blockage of the urethra.
Injuries: Accidents, surgical procedures, or the insertion of a catheter can injure the urethra and leave scar tissue that narrows it.
Infections: Chronic urinary tract infections, sexually transmitted diseases such as gonorrhea, or other inflammatory diseases can lead to scarring and narrowing of the urethra.
Congenital (born) causes: Some people are born with a narrow or abnormal urethra, which can cause problems later on.
Radiation therapy: In patients who have received radiation therapy to the pelvic area for cancer or other conditions, the urethra may be damaged by the tissue.
Other causes: Rare causes include tumors, certain medications, or chronic inflammation.
In severe cases, a complete blockage of the urethra may occur, which is a medical emergency.
History: The doctor will ask about your symptoms, medical history, and possible risk factors.
Clinical examination: A physical examination can help detect abnormalities.
Urethrogram: A contrast agent is injected into the urethra to visualize the stricture under X-ray.
Cystoscopy: A thin, flexible endoscope is inserted into the urethra to directly view the stricture.
Ultrasound: An ultrasound can help detect associated complications such as urinary retention or bladder remnants.
Treatment for urethral stricture depends on the severity of the condition and may include the following options:
Urethral dilation: In milder cases, the urethra can be dilated using a catheter to relieve the stricture.
Urethrotomy: A surgical procedure in which the narrowed area is cut open to widen the urethra.
Urethroplasty: In more severe cases, the damaged tissue can be removed and replaced with healthy tissue.
Stents or catheters: In some cases, a stent or catheter can be inserted to keep the urethra open.
Laser treatment: A laser can be used to remove the scar tissue in the urethra and relieve the stricture.
Treatment of infections: If an infection is causing the stricture, antibiotic treatment will be prescribed.
How can I tell if I have urethral stricture?
If you have difficulty urinating, notice a weak urine stream, or experience pain when urinating, you should see a doctor. These symptoms may indicate urethral stricture.
Can urethral stricture heal on its own?
In most cases, urethral stricture does not heal on its own and requires medical treatment. If left untreated, it can worsen and lead to further complications.
Is surgery necessary?
Not always. In many cases, urethral stricture can be treated with minimally invasive methods. However, severe or recurring strictures may require surgery.
What happens if the stricture is left untreated?
If left untreated, urethral stricture can lead to chronic urinary tract infections, urinary retention, or even complete bladder blockage, which in some cases can lead to kidney damage.
