What are the causes of urethral stricture?

The following are common causes of scarring or narrowing of the urethra:

  • Trauma from injury or accidents with damage to the urethra or bladder (for example, falling on a frame of a bicycle between the legs, or a car accident)
  • Pelvic injury or trauma
  • Previous procedures involving the urethra (urinary catheters, surgeries, cystoscopy)
  • Previous prostate surgery (TURP or transurethral resection of the prostate for prostate enlargement)
  • Prostate enlargement
  • Cancer of the urethra (rare)
  • Infections of the urethra (sexually transmitted diseases or STDs, urethritis, gonorrhea, chlamydia)
  • Prostate infection or inflammation (prostatitis)
  • Previous hypospadias surgery (a congenital birth defect in which the opening of the urethra is on the underside of the penis instead of the tip)
  • Congenital malformations of the urethra, which rarely can cause urethral stricture in children

According one study, about one-half of causes of urethral stricture are from medical procedures and manipulation of the urethra or nearby structures (surgeries, catheter insertion, etc.). In about one-third of cases, no identifiable cause was found.

What are the symptoms and signs of urethral stricture?

Symptoms of urethral stricture can range from no symptoms at all (asymptomatic), to mild discomfort, to complete urinary retention (inability to urinate).

Some of the possible symptoms and complications of urethral stricture include the following:

  • Difficulty starting urine flow
  • Painful urination (dysuria)
  • Urinary tract infection (UTI)
  • Urinary retention
  • Incomplete emptying of bladder
  • Decreased urine stream
  • Dribbling of urine
  • Spraying or double streaming urine
  • Blood in the urine (bloody or dark-appearing urine) known as hematuria
  • Blood in the semen
  • Urinary incontinence (loss of bladder control)
  • Pelvic pain
  • Discharge from the urethra
  • Reduced ejaculation force
