虽然大部分膀胱癌为乳头状癌,癌细胞脱落迅速,但大多数患者井不能从检查尿中新生物细胞来发现膀胱肿瘤。失败的原因可能是由于某些标本的瘤细胞未能辨认出来,或是因为尿中瘤细胞数量非常稀少,以致查到的机会大为减少。新鲜的膀胱冲洗液可以避免这一缺点。材料和方法:膀胱冲洗液和尿液取自160例未经选择的患者,其中113例有膀胱癌或膀胱癌的病史,47例无肿瘤。 Although most bladder cancers are papillary carcinomas, cancer cells shed quickly, but most patients are unable to detect bladder tumors from examining newborn cells in the urine. Failure may be due to some specimens of tumor cells can not be identified, or because the number of neoplastic cells in urine is very small, resulting in a greatly reduced chance of finding. Fresh bladder irrigation solution can avoid this disadvantage. MATERIALS AND METHODS: Bladder flushing fluid and urine were taken from 160 patients who had not been selected, of whom 113 had a history of bladder or bladder cancer and 47 had no tumor.
