ABSTRACT
A urethral stricture is a scar and narrowing at one or more points in the urethra and of variable severity. This scar may compromise voiding and cause incontinence, bleeding, stones and even renal failure. This problem is almost invariably restricted to men and boys and is often secondary to injury (including catheter trauma) or inflammation. In many patients, no clear source of an event such as this can be recalled. Urethral strictures may be found in the urethra of women after severe pelvic trauma or after misguided urethral dilatations and over-stretching of the urethra.
