尿性隐血+2怎么回事
基本上潜血在不同年龄及性别上也有不同的考虑,例如年轻女性在验尿时发现潜血,除了临床症状外,应该问一问是否正当生理期,膀胱炎是常见的原因;但是如果是30-40岁的男性,如果没有明显的发炎症状,有时候应该照张腹部X光片,看看是否有结石的可能,老年男性的血尿或潜血,前列腺肥大列为主要考虑因素之外,也应该接受进一步的静脉内肾盂造影或超音波检查,看看泌尿系统是否有肿瘤。除此之外,尿液细胞学检查,看看尿液中脱落的泌尿系统上皮是否有恶性细胞的存在,也是检测是否有恶性肿瘤的方法之一,如果X光检查、超音波检查及尿液细胞学检查均为正常,仍有潜血的存在,最好再接受膀胱尿道镜检查,因为X光、超音波有限制性,并非所有的肿瘤都可显现,这时候只有借助肉眼直接观察较小的病灶(膀胱尿道镜)了,如果这些检查均无不正常的发现,我们将这种潜血或血尿称之“良性原因不明性血尿”,可能与身体的免疫机制有关,日后只需定期追踪即可。
