Our experience with urethral strictures in boys during a 15-year period confirms the findings of others that the most common etiology is iatrogenic. Traumatic and inflammatory strictures are rare. The congenital stricture differs fundamentally from acquired types of urethral strictures and would be termed more appropriately congenital urethral membrane. Urethral dilation and/or urethrotomy was unsuccessful in 47% of our patients, leading to secondary formation of a new stricture in 2 instances. However, urethroplasty was successful in 83% of our cases and seems to be indicated when 2 or more dilations are required.
我们在15年期间对男孩尿道狭窄的经验证实了其他人的发现，即最常见的病因是医源性的。创伤性和炎性狭窄很少见。先天性狭窄与后天性尿道狭窄在本质上不同，更恰当地应称为先天性尿道膜。在我们47%的患者中，尿道扩张和/或尿道切开术未成功，导致2例患者继发形成新的狭窄。然而，在我们83%的病例中，尿道成形术是成功的，当需要进行2次或更多次扩张时似乎有必要进行尿道成形术。
