Non-hair-bearing skin should be utilized when grafting is necessary in carrying out urethroplasty for stricture or hypospadius repair. Occasionally this is not possible, or hair-bearing skin is used inadvertently. Traditionally electrocoagulation has been the method used for epilation when intraluminal hair has become a problem, such as interfering with flow, being foci for recurring urinary tract infection, or acting as a nidus for calculus formation. Electrocautery is also used at the time of grafting in an attempt to prevent the growth of hair when hair-bearing skin is utilized. Unfortunately, because of lack of penetration, the hair follicles are not destroyed and the epilating procedure fails or is only partially successful. The neodymium: YAG (Nd:YAG) surgical laser can photocoagulate tissue to a depth up to 5.0 mm and thus has the ability to destroy hair follicles. We report three cases presenting with clinical problems directly related to hair-bearing urethral grafts successfully treated by Nd:YAG epilation.
在进行尿道狭窄或尿道下裂修复的尿道成形术需要植皮时，应使用无毛皮肤。偶尔这是不可能的，或者无意中使用了有毛皮肤。传统上，当腔内毛发出现问题，如干扰尿液流动、成为复发性尿路感染的病灶或作为结石形成的病灶时，电凝术一直是用于脱毛的方法。在使用有毛皮肤进行植皮时，也会使用电灼术以试图防止毛发的生长。不幸的是，由于缺乏穿透力，毛囊未被破坏，脱毛程序失败或仅部分成功。钕：钇铝石榴石（Nd:YAG）手术激光可以将组织光凝至5.0毫米的深度，因此有能力破坏毛囊。我们报告了三例与有毛尿道移植物直接相关的临床问题通过Nd:YAG脱毛成功治疗的病例。
