It can be deduced from statistics, that injuries are causative for a urethral stricture in the majority of cases.
However, these injuries do not have to be severe by any means, to entail a urethral stricture. 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. Nevertheless, it has to be made perfectly clear, that the majority of those procedures stay without any negative effects for the patients. Albeit with all invasive diacritic and therapeutic procedures, there has to be special diligence regarding the urethra. The transurethral resection of the prostate is one of the most common prostate surgeries. After this procedure, approximately five per cent of the patients suffer from a urethral stricture. Concerning women, there are particularly surgeries due to incontinence that can result in a urethral stricture. Another example of posing a risk are injuries of the urethra, which can arise during delivery and result in a urethral stricture.
