2014 年 1 月 31 日3820

  对于人们来说,肾积水是比较常见的一种病,所以我们应积极的预防肾积水的产生,但是却都不知道肾积水的相关知识,下面小编将为大家详细的讲解导致肾积水的原因。

  导致肾积水的原因?

  1、外来病变造成的梗阻包括动脉、静脉的病灶;女性生殖系统病变;盆腔的肿瘤、炎症;胃肠道病变;腹膜后病变(包括腹膜后纤维化、脓肿、出血、肿瘤等)。

  2、下尿路的各种疾病造成的梗阻,如前列腺增生、膀胱颈部挛缩、尿道狭窄、肿瘤、结石甚至于包茎等,也都会造成上尿路排空困难而形成肾积水。

  3、节段性的无功能:由于肾盂输尿管交界处或上段输尿管有节段性的肌肉缺如、发育不全或解剖结构紊乱,影响了此段输尿管的正常蠕动,造成动力性的梗阻。此种病变如发生在输尿管膀胱入口处,则形成先天性巨输尿管,后果为肾、输尿管扩张与积水。

  4、炎症后或缺血性的疤痕导致局部固定。膀胱输尿管回流造成输尿管扭曲,加之输尿管周围纤维化后最终形成肾盂输尿管交界处或输尿管的梗阻。

  5、肾盂与输尿管的肿瘤、息肉等新生物,可为原发也可能为转移性。结石和外伤及外伤后的疤痕狭窄。

  肾积水的原因有很多,大多数人的肾积水是由不良的习惯导致的,所以生活中需要我们养成良好的习惯。
