膀胱肿瘤是泌尿系统最常见的肿瘤。1972年上海市区每10万人中膀胱癌发病人数为5.49人,美国78年患膀胱癌人数为3万人。其中T_1期肿瘤包括浸润不超出粘膜下层和无浸润的全部乳头状肿瘤,占膀胱肿瘤80％。传统的治疗方法是膀胱灌注抗癌药物,经尿道切除或膀胱部分切除治疗,但存在以下几个问题:1.膀胱灌注抗癌药物治疗,只是部分有效,对肿瘤直径在1cm以上者治疗就比较困难,而且治疗时间长。2.经尿道电灼只限于小肿瘤,电切治疗目前还不普及,

Transurethral electrosurgery is limited to small tumors, electrosurgical treatment is not yet universal,
