A synthetic contact sapphire endoprobe attached to the quartz fiber of a neodymium:yttrium aluminum garnet (Nd:YAG) laser had been used in the transurethral treatment of bladder tumors. A total of 68 operations have been carried out in 48 patients. The contact probe was placed directly into the tumor under direct vision. Using 15-20 watts of laser energy, the tumor blanched and underwent necrosis. The technique was easy to apply, and bleeding was minimal. Damage to the ureteral orifice and ureter in the bladder wall at repeat cystoscopy appeared less than with conventional electrocautery or noncontact laser treatment. The technique of contact Nd:YAG laser surgery will have an important role in the transurethral treatment of bladder tumors.
一种连接在钕钇铝石榴石（Nd:YAG）激光石英纤维上的合成接触式蓝宝石内探头已用于膀胱肿瘤的经尿道治疗。共对48例患者进行了68次手术。接触探头在直视下直接置于肿瘤内。使用15 - 20瓦的激光能量，肿瘤变白并发生坏死。该技术易于应用，且出血极少。在重复膀胱镜检查时，膀胱壁上输尿管口和输尿管的损伤似乎比传统电灼或非接触激光治疗要小。接触式Nd:YAG激光手术技术在膀胱肿瘤的经尿道治疗中将发挥重要作用。
