尿道扩张术的原理是怎样的 李强 中国医学科学院整形外科医院 尿道扩张术，就是指一道器械，由细到粗，逐渐的把尿道增粗，利用的是尿道本身的组织弹性，和局部的水肿的减轻，和局部的比较薄弱瘢痕的一种撕扯，使尿道保持比较通畅的状态。但是这种状态通常来说，不是效果很充分，所以说有些时候，咱们在进行扩张以后，还可以进行支撑管的支撑，让它维持更持久的状态，这样可能效果会更佳一些。但是对于非常严重的狭窄，比如说，很细的地方都不能探入的，实际上是不太适合进行尿道扩张的，对于一些整个路径不清晰的，也不易进行尿道扩张，以防形成假道。 What is the principle of urethral dilatation Urethral dilatation, It means a piece of equipment, From thin to thick, The urethra is gradually enlarged, It uses the elasticity of the urethra itself, And local edema reduction, It's a kind of tear with weak scar, Keep the urethra in a relatively unobstructed state. But it's a state of general, Not very effective, So sometimes, After we expanded, It can also support the support pipe, Keep it in a more permanent state, This may work better. But for very severe stenosis, for instance, It can't be found in very small places, In fact, it is not suitable for urethral dilatation, For those whose entire path is not clear, It's not easy to dilate the urethra, To prevent the formation of a false path.
