Urethral Stricture
Overview
A urethral stricture is an abnormal narrowing of the urethra — the tube that carries urine out of the body — caused by scar tissue. It can significantly restrict urine flow and, over time, affect the bladder and kidneys if left untreated.
Symptoms
Causes
Causes include prior injury, previous catheter use or surgery, urethral infections, and certain inflammatory skin conditions that scar the urethral lining.
Risk Factors
Diagnosis
A urine flow test, a retrograde urethrogram (a specialized X-ray), and sometimes cystoscopy confirm the stricture's exact location and length, which guides treatment choice.
Complications If Untreated
Untreated strictures can worsen over time and lead to bladder stones, recurrent infections, urinary retention, and eventually kidney damage from chronic back-pressure.
Treatment Options
Prevention Tips
Careful catheter technique, prompt treatment of urethral infections, and gentle handling during any urological procedure all help reduce the risk of scarring.
Lifestyle Advice
Anyone with a history of catheterization or pelvic injury who notices a weakening stream should get evaluated promptly rather than waiting for it to worsen.
