The cause of congenital ureter dilatation as well as its nomenclature are controversial. The question arises as to whether there is a common denominator for this multiform syndrome. There are abundant possibilities of disturbance during the development of the ureter. The muscle coat of the developing fetal ureter reacts with an alteration of the wall structure. In view of the multiplicity of etiological factors which can affect the development of the ureter, a disturbance of intrauterine urinary drainage which is transient or permanent probably has a functional or mechanical basis. At any events, a subvesical obstruction, which may also be the cause, must be excluded.
先天性输尿管扩张的病因及其命名存在争议。对于这种多形态综合征是否存在一个共同的要素，这一问题随之而来。在输尿管发育过程中存在大量干扰的可能性。发育中的胎儿输尿管肌层会对管壁结构的改变产生反应。鉴于影响输尿管发育的病因因素多种多样，宫内尿液引流的短暂或永久性干扰可能具有功能或机械性基础。无论如何，必须排除也可能是病因的膀胱下梗阻。
