Urethral stricture is the narrowing of the urethra, usually due to scar tissue or inflammation from an infection. The urethra is the tube that transports urine from the bladder to the urethral orifice, so if it becomes narrowed it can cause difficulty and pain when urinating. In severe cases, it can cause urinary retention (inability to urinate).
Common causes of urethral stricture include injury to the groin and thighs area (straddle injury) and penile fracture. Both can cause scarring, especially if medical treatment was not sought at the time. Medical conditions, such as problems with the kidneys or bladder, often mean that patients are required to wear a catheter to assist urination. Although this is a very useful device (and sometimes absolutely necessary), it can lead to scarring in the urethra, especially if it has not been fitted well.
In rare cases, urethral stricture can develop as a result of a congenital condition that affects males, known as hypospadias. This is a condition whereby the urethra does not descend to the normal position of the tip of the penis. Rather, the opening through which urine is passed (the urethral meatus) appears somewhere along the underside of the penis shaft or even in the scrotal area. Usually, boys born with this condition have reconstructive surgery early in life, so that they do not have any problems with urination later in life. Nonetheless, this kind of surgery can lead to scarring, which is why regular check-ups are necessary to avoid complications.
