Urethral duplication (UD) is a rare congenital anomaly. In UD, there is in addition to a normally positioned urethra an accessory urethra arising from the bladder, bladder neck or the proximal urethra and terminating anywhere between the base of the penis along the ventral surface and the glans penis. The embryologic development of UD remains to be clearly elucidated and the etiology of the condition is unknown. We present our experience with a 4 year old boy who presented with urethral duplication.
尿道重复畸形（UD）是一种罕见的先天性异常。在尿道重复畸形中，除了正常位置的尿道外，还有一条副尿道，它起源于膀胱、膀胱颈或近端尿道，终止于阴茎底部沿腹侧表面至阴茎头之间的任何位置。尿道重复畸形的胚胎发育仍有待明确阐明，该病的病因尚不清楚。我们介绍了我们对一名患有尿道重复畸形的4岁男孩的治疗经验。
