Urethral Stricture
A urethral stricture is a narrowing of the urethra, the tube that carries urine out of the body, usually from scarring. It makes urinating difficult and mainly affects men.
Causes & risk factors
- Injury to the urethra or pelvis
- Previous catheter or urinary procedures
- Infection or inflammation of the urethra
- Radiotherapy to the area
- Sometimes no clear cause
Common symptoms
Tests & diagnosis
- Uroflowmetry (flow test)
- Retrograde urethrogram (X-ray)
- Cystoscopy
- Urine test
- Post-void residual ultrasound
Treatment & management
- Dilatation (stretching) of the narrowed segment
- Endoscopic incision of the stricture
- Urethroplasty (reconstructive surgery) for lasting cure
- Treating any infection
- Follow-up, as strictures can recur
When to see a doctor urgently
- Being suddenly unable to pass urine — emergency
- A progressively weaker urine stream
- Repeated urine infections
- Blood in the urine with difficulty urinating

Frequently asked questions
Can a urethral stricture come back after treatment?
Simple stretching or incision can recur. Reconstructive surgery (urethroplasty) offers the most durable results for suitable strictures.
Why does it mostly affect men?
The male urethra is much longer and more exposed to injury, infection and procedures, so strictures are far more common in men.
