钬激光是一种新型的固体激光,呈脉冲式发射,方向性好,具有良好的汽化、切割组织和凝固止血作用。其组织穿透深度浅,损伤小,切割精确,术后瘢痕形成少,无电场效应,不会引起闭孔神经反射,手术安全性高,且可通过软光纤传送,特别适合泌尿外科的腔内手术。现就其在泌尿系统肿瘤、前列腺增生、泌尿系结石、泌尿系统狭窄等疾病治疗中的应用进行综述。 Holmium laser is a new type of solid laser, pulsed emission, good direction, with good vaporization, cutting tissue and coagulation hemostasis. Its tissue penetration depth shallow, small injury, accurate cutting, scar formation after surgery, no electric field effect, will not cause obturator nerve reflex, high safety surgery, and can be transmitted through the soft optical fiber, especially for urological cavity surgery. Now on its urinary tract cancer, benign prostatic hyperplasia, urinary stones, urinary tract stenosis and other diseases in the treatment of applications are reviewed.
