膀胱癌的复发和转移频率占泌尿生殖道肿瘤的第二位,是治疗上的重要问题。目前采用的治疗方法有许多危险和副作用,以致必须寻找某些新的方法。现在一致的看法是对表浅性膀胱癌宜行经尿道切除术(TUR),对浸润性癌有指征行全膀胱切除。但令人惊异的是,对浸润性膀胱癌行根治术后的5年生存率与TUR相比并没有被证实是否具有优势。而TUR的缺点在于不能准确地掌握肿瘤浸润的深度。此缺点却能通过Nd-YAG激光装置来克服。用这一装置人们不接触肿瘤而能破坏至6～7mm深度,同 Bladder cancer recurrence and metastasis frequency of genitourinary tumors account for the second, is the treatment of important issues. There are many dangers and side effects of the current treatment methods that necessitate some new methods. The consensus now is that transurethral resection (TUR) of superficial bladder cancer should be performed and total cystectomy is indicated for invasive cancer. Surprisingly, the 5-year survival after radical surgery for invasive bladder cancer has not been shown to be an advantage over TUR. The disadvantage of TUR is that it can not accurately grasp the depth of tumor infiltration. This disadvantage can be overcome by the Nd-YAG laser device. People do not touch the tumor with this device can be destroyed to 6 ~ 7mm depth, with
