显微外科技术在尿道下裂修复中的应用

Operation for Hypospadias Applying Microsurgical Technique

采用显微外科技术行阴囊纵膈皮瓣尿道下裂修复术18例,均获成功。其手术要点为:将阴茎腹侧纤维索条切除,充分伸展阴茎;皮瓣保留足够长度与宽度,确保血运;在显微镜下采用7—0尼龙丝线缝合,形成皮管,不缝皮肤,只缝皮下。硅胶管支架引流,加压包扎阴茎。本文对手术成功的原因进行了初步讨论。

One stage repair of hypospadias with scroto-septal pedicle flap under operative microscope has been performed in eighteen patients(3～30 years)since 1988 and satisfactory results were achieved in all patients.The main procedure included:excision of the ventral fibrous cord of the penis to make it extend fully:sufficent length and width of the skin flap was preserved to maintain blood supply:the flap was formed a tube by suture with nylon while only the hypodermis was sutured but not the skin: drainage by a silicon tube and compression bandage the penis.The cause of success in operation has been discussed as well.
