根据接触式激光对组织具有汽化切割和凝固的功能，采用接触式激光经尿道治疗膀胱肿瘤21例，其中20例为低分级移行上皮细胞癌，1例为内翻状乳头状肿瘤，结果除2例术后非治疗区域发生肿瘤外（9．5％），其余均未见复发，获得满意的临床效果。认为接触式激光治疗浅表非浸润性肿瘤操作简单，容易掌握，但需严格掌握手术指征。该术式与经尿道膀胱肿瘤电切术比较有出血少、无闭孔神经反射、无伤口肿瘤种植、对患者打击小、恢复快、老年高危患者也可适用等优点，是治疗浅表膀胱肿瘤理想的手术方法。存在的不足是手术耗时较多。若将两者结合起来，可发挥各自优势。
According to contact laser on the organization with the function of vaporization and coagulation, the use of contact laser transurethral resection of bladder cancer in 21 cases, of which 20 cases of low-grade transitional cell carcinoma, a case of inverted papillary tumors, the results in addition to 2 Cases of non-treated area after surgery occurred outside the tumor (9.5%), the rest were no recurrence, to obtain satisfactory clinical results. That the contact laser treatment of superficial non-invasive tumor simple, easy to grasp, but the need to strictly grasp the indications for surgery. The surgical resection of transurethral resection of bladder tumor compared with less bleeding, no obturator nerve reflex, no wound tumor implantation, the patient hit small, fast recovery, high risk patients can also be applied, etc., is the treatment of superficial bladder tumors The ideal surgical method. The shortcomings are more time-consuming surgery. If the two combine to play their respective advantages.
