Urethral stricture usually arises because there has been damage to the mucosa lining the urethra.
This scarring is usually due to congenital, inflammatory, infectious or traumatic reasons, although it can also occur due to bladder manipulations or medical procedures involving catheterization or the introduction of any other instrument through the urethra.
Thesymptoms presented by urethral stricture are mainly obstructive of the urinary tract:
Some patients may present other symptoms such as erectile dysfunction or difficulty ejaculating.
Many of these symptoms are common to other diseases of the urinary tract or prostate. Therefore, to confirm urethral stricture it is necessary to perform different diagnostic tests.
In general, urethral stricture affects men more than women due to the fact that the length of this duct is greater in men. Although the cause of this scarring within the urethra is sometimes unknown, it is usually due to congenital, inflammatory, infectious or traumatic reasons, although it can also be caused by urethral tumors, dermatological diseases and bladder manipulations or medical procedures involving catheterization or the introduction of any other instrument through the urethra, such as an endoscope.
Stenosis usually arises because there has been damage to the mucosa lining the inside of the urethra. This tissue damage, when repaired by the body in a natural way, can generate a scar that prevents urine from flowing normally when urinating.
It may be due to congenital, inflammatory, infectious or traumatic reasons. It can also occur due to urethral tumors, dermatological diseases or medical procedures involving the introduction of an instrument through the urethra.
If left untreated, the situation may worsen over time. As the obstruction increases, the bladder will begin to hold urine and problems such as acute urinary retention, bladder diverticula, hydronephrosis, renal failure or stones in the bladder, kidney or ureter may occur.
The symptoms of urethral stricture are very common to other diseases of the urinary tract or prostate. Therefore, to confirm the problem it is necessary to perform diagnostic tests.
This will depend on the location of the stricture, the length and the previous surgeries we have performed on the stricture. The first step is to perform an internal urethrotomy, but in many cases more aggressive surgeries will have to be performed.
