接触式激光治疗膀胱肿瘤的临床观察

Contact laser treatment of bladder tumors

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。

21 cases with urinary bladder tumors were treated with satisfied clinical results us- ing contact laser system,which is based on the function that laser can vaporizo and coagulate tis-sues simutaneously. It is most suitable for the treatment of non-invasive superficial bladder tumors.Tumors can be easily shaved by pushing the probe forward- Compared with conventional transurethral resection method, this technique has the advantages of less bleeding, no obturator nerve renex and no implantation of viable tumor cells in the course of resection. DUe to its less in-jury and quick recovery,it is suitable for poor risk elderly patients. It offers and ideal method to treat superficial bladder tumors. Its disadvantage is time-consuming. The combining use of prompt TURBTand contact laser which can minimize bleeding provides a perfect method in the treatment of urinary bladder tumors.
