肾囊肿应该做哪些检查?

来源:华人健康网 | 发布时间:2011-09-15 00:03:25 | www.chinesejk.com
  一、基本检查
  (1)尿的检查 尿常规正常,若囊中压迫肾实质或合并有囊内感染,尿中可出现小量红细胞和白细胞。
  (2)B超 能了解囊肿的个数、大小、囊壁的情况。并可与肾实质性肿块相鉴别,为首选检查方法。典型的 B超表现为病变区无回声,囊壁光滑,边界清楚;当囊壁显示不规则回声或有局限性回声增强时,应警惕恶性变;继发感染时囊壁增厚,病变区有细回声,囊内有出血时回声增强。当显像提示有多个囊肿时,应与多房性囊肿,多囊肾相区别。
  (3)静脉肾盂造影(ivp)能显示囊肿压迫肾实质的程度,并可与肾积水相鉴别。
  二、进一步检查
  CT,对 B超检查不能确定者有价值,囊肿伴出血、感染、恶变时,呈现不均质性,CT值增加,当 CT显示为囊肿特征时,可不必再作囊肿穿刺。
