It can be deduced from statistics, that injuries are causative for a urethral stricture in the majority of cases. Already very small injuries can lead to scarring, which in turn leads to a stricture. Those microscopically small injuries can happen in consequence of a bladder examination, for instance, or they can emerge during positioning a urinary catheter.
Accidents can also be a cause for urethral stricture. There are several accidents, which are considered to be distinctive for suchlike injuries. There are pelvic fractures, for example, or blunt traumas of the genital areas as well. These so called straddle traumas can be induced by falling off a bike, for instance. In consequence of the damage the urethra can be injured, too, or at worst it could tear. In the event of a minor injury, the subsequent scarring of the tissue can eventually lead to a urethral stricture.
