膀胱癌发病率占泌尿生殖系统肿瘤的第一位,膀胱癌的诊断,临床分期对于治疗方法的选择和预后具有重要意义。但目前对膀胱癌的诊断尚无确切的实验室诊断指标,多靠膀胱镜、病理和B超等手段,不易推广普及和早期发现。本文作者采用放射免疫分析方法对尿液中的CEA含量进行了检测,为膀胱癌的诊断提供了一种简便可靠的实验室指标。 Bladder cancer incidence of genitourinary tumors account for the first one, the diagnosis of bladder cancer, clinical stage for the treatment of choice and prognosis of great significance. However, the diagnosis of bladder cancer there is no exact laboratory diagnostic indicators, mostly by cystoscopy, pathology and B-ultrasound and other means, not easy to promote the popularization and early detection. The author used radioimmunoassay to detect the content of CEA in urine and provided a simple and reliable laboratory index for the diagnosis of bladder cancer.
