肾癌的症状

来源:华人健康网 | 发布时间:2011-08-20 09:17:03 | www.chinesejk.com
肾癌的初步诊断首先依据临床表现。具有典型的血尿、腰痛、肿块等症状的患者,诊断并不困难,但这类肿瘤往往已属晚期。有些患者的临床表现很不典型,症状不在泌尿系统,并有少数病员,转移性癌的症状可早于肾癌本身的症状,这样诊断就比较困难。天津医学院报道50例肾癌中,有些病员单纯出现肾外表现,而无血尿、肿块、腰痛三大症状。有发热2例、贫血3例、胃肠功能紊乱1例、左锁骨上淋巴结转移1例。并指出不少患者肾外表现出现在三大症状之前,是肾癌的早期信号。应提高警惕,追寻发热、贫血、肝功能障碍、红细胞增多症,高血压、高血钙等肾外表现的原因。
血尿是肾癌最常见的症状。肾癌引起的血尿大多是无痛性全血尿,一般都间歇出现。出血不多时尿液呈浓茶样或暗红色,出血量多时尿液呈鲜红色。尿常规样查,主要是红细胞增多,蛋白与白细胞均不多。
