Ho-YAG laser (Medoptotech) operates in impulse regimen with transmission of radiation along the fiber 400-600 microns in diameter (mean power 12 W, impulse rate 1-15 Hz, energy of 1 impulse 0.7-1.5 J, its duration 300 microseconds. These parameters provide the effect of intensive biotissue evaporation, dissection of contact tissue, disintegration of concrements, hemostasis. Ho-YAG laser was employed for treatment of 8 patients with urethral polyp, 4 with stricture of the bladder neck and urethra, 5 with prostatic adenoma, 12 with bladder tumor, 10 with ureterolith, 5 with uroliths, 4 with penile lesions, 2 with ureteral stricture, 4 with ureterocele. Ho-YAG laser was used primarily for endoscopic interventions. Its use for open surgery is also promising. Further practical experience with Ho-YAG laser will provide additional information on its indications in urological diseases.
钬-钇铝石榴石激光（Medoptotech公司生产）以脉冲模式运行，辐射通过直径为400 - 600微米的光纤传输（平均功率12瓦，脉冲频率1 - 15赫兹，单个脉冲能量0.7 - 1.5焦耳，脉冲持续时间300微秒。这些参数可实现生物组织的强烈蒸发、接触组织的切割、结石的破碎以及止血效果。钬-钇铝石榴石激光用于治疗8例尿道息肉患者、4例膀胱颈和尿道狭窄患者、5例前列腺腺瘤患者、12例膀胱肿瘤患者、10例输尿管结石患者、5例尿路结石患者、4例阴茎病变患者、2例输尿管狭窄患者、4例输尿管囊肿患者。钬-钇铝石榴石激光主要用于内镜干预。其在开放手术中的应用也很有前景。钬-钇铝石榴石激光的进一步实践经验将为其在泌尿系统疾病中的适应证提供更多信息。
