To report a novel method for treating anterior urethral valves in children using the holmium:YAG laser.
A 2-year-old boy presented with symptoms of urinary-outflow obstruction. A micturating cystourethrogram (MCUG) revealed an abrupt narrowing of the penile urethra. At cystourethroscopy, an anterior urethral valve without a diverticulum was visible. This was ablated endoscopically using the Ho:YAG laser. The child voided successfully and was discharged the next day. Repeat MCUG 6 months later revealed a normal-caliber urethra.
Holmium:YAG laser ablation of anterior valves is a minimally invasive treatment modality that provided a satisfactory result and appears to be very promising.
报告一种使用钬激光治疗儿童前尿道瓣膜的新方法。
一名2岁男孩出现排尿梗阻症状。排尿性膀胱尿道造影（MCUG）显示阴茎尿道突然变窄。在膀胱尿道镜检查中，可见一个无前庭的前尿道瓣膜。使用钬激光对其进行了内镜下切除。患儿排尿成功，次日出院。6个月后复查MCUG显示尿道管径正常。
钬激光消融前尿道瓣膜是一种微创治疗方式，效果满意，前景广阔。
