肾萎缩

来源:华人健康网 | 发布时间:2011-08-17 11:57:32 | www.chinesejk.com
  肾萎缩是一个病理解剖学名词,也就是说肾脏萎缩,体积明显减小,也称终末期肾脏。这时肾小球肾小管(即肾单位)已绝大部分或全部破坏,肾脏已失去生理功能。通常对慢性肾衰患者进行肾脏B型超声检查,就可以了解肾脏是否萎缩,而且这种检查方法对患者没有损害。肾脏B超的正常值为:左肾长径8.1~11厘米,横径5.5~7厘米,厚度4~5厘米;右肾长径7.9~10.5厘米,横径5.5~7厘米,厚度4~5厘米。倘若测值明显小,说明肾脏已萎缩,处于终末期,预后不佳,治疗效果也差。倘若测值略小或正常,说明是中期或早期,治疗效果好,预后良。因而作为从事肾脏病的临床医生,了解患者肾脏大小,对分析病情、判断预后、估计疗效均有十分重要的意义。
