Duplication of the urethra is a rare congenital anomaly. While it is true that in some instances reconstructive surgery is not necessary, those cases that require repair pose a significant challenge to the urologist. Our experience with 3 cases illustrates the potential complexity of this deformity. Two patients presented with significant renal compromise secondary to bladder outlet obstruction and required reconstruction of the entire anterior urethra. The third patient presented with a urethral fistula after circumcision and repair was done by ventral-to-dorsal urethrourethrostomy. A workable classification of duplicated and accessory urethra is outlined. This classification is based on the source of the secondary channel, its point of emptying (that is internal, external or blind) and the relationship of the secondary channel to the normal urethra (that is dorsal or ventral).
尿道重复是一种罕见的先天性异常。虽然在某些情况下确实不需要进行重建手术，但那些需要修复的病例对泌尿外科医生来说是一项重大挑战。我们处理3例病例的经验说明了这种畸形的潜在复杂性。两名患者因膀胱出口梗阻继发严重肾损害，需要重建整个前尿道。第三名患者包皮环切术后出现尿道瘘，通过腹侧至背侧尿道吻合术进行修复。本文概述了一种可行的重复尿道和副尿道分类方法。这种分类基于副尿道的来源、其排空点（即内部、外部或盲端）以及副尿道与正常尿道的关系（即背侧或腹侧）。
