肾囊肿的检查方法

来源:华人健康网 | 发布时间:2011-08-18 12:25:02 | www.chinesejk.com
  比较可靠的方法有X线造影、肾脏B型超声检查、放射性核素扫描及CT检查。在肾囊肿时,泌尿系X线造影可能见到肾盂、肾盏受压变形,但边缘光滑,无破坏。肾囊肿不是肿瘤,但极易与肿瘤相混淆,因此肾囊肿与肾恶性肿瘤的鉴别十分重要。二者的鉴别方法可用肾实质性断层造影或肾动脉造影。肾实质断层摄影时,囊肿部位影像浅,肿瘤部位影像深;肾动脉造影时,囊肿部位血管稀疏,无造影剂浓聚,肾恶性肿瘤则因血管丰富,有造影剂浓聚。怀疑囊肿恶性变时,可进行囊肿穿刺,抽出囊液进行常规检查及脱落细胞检查;也可向囊肿内注入造影剂,检查囊壁有无肿瘤。B型超声和CT很容易将肾囊肿和肾实质性肿瘤区别开来,因此,十分理想的检查方法。
