To assess the variability of membranous folds in the posterior urethra and their relationship to urethral obstruction.
Endoscopic video recordings of 19 boys with a membranous lesion in the posterior urethra were obtained over a 2.5-year period. Six had an endoscopy after a prenatal diagnosis of obstructive uropathy and 13 boys presented with either a urinary tract infection or hematuria.
Young's type I and type III appearances were seen in all with an obstructive membrane, and those with a less obstructing membrane probably had incidental pathologic conditions.
These observations support the thesis that the congenital attachment of the verumontanum to the anterior wall of the posterior urethra is the embryologic fore-runner to the congenital obstruction of the posterior urethra, and that there may be a variable degree of persistence of that attachment, which in some boys is not obstructive.
评估后尿道膜状皱襞的变异性及其与尿道梗阻的关系。
在2.5年的时间里，获取了19名后尿道有膜状病变男孩的内镜视频记录。其中6名在产前诊断为梗阻性尿路病后接受了内镜检查，13名男孩因尿路感染或血尿就诊。
所有有梗阻性膜的患者均出现杨氏I型和III型表现，而膜梗阻较轻的患者可能伴有偶然的病理情况。
这些观察结果支持以下论点，即精阜与后尿道前壁的先天性附着是后尿道先天性梗阻的胚胎学先兆，并且该附着可能存在不同程度的持续存在，在一些男孩中并不造成梗阻。
