Seven cases of bladder duplication are described, and compared with 27 cases of urethral duplication. Bladder duplication was collateral while urethral duplication was usually in the sagittal plane. The conditions may coexist when the duplication of the bladder extends caudally to produce a collateral urethral duplication, but in one boy bladder duplication was associated with 4 urethrae in the sagittal plane. In 5 cases the bladders were united; in 2 cases, one bladder was excised. The results were satisfactory in 6 and in one the bladder failed to empty. The basic defects that lead to duplication are unknown. Several features of the conditons suggest that there are different aetiologies in each type. There are similarities with the exstrophy epispadias complex. Even when there are major abnormalities in other systems the general and urological prognosis is good.
本文描述了7例膀胱重复畸形的病例，并与27例尿道重复畸形的病例进行了比较。膀胱重复畸形是旁侧性的，而尿道重复畸形通常位于矢状面。当膀胱重复畸形向尾侧延伸导致旁侧性尿道重复畸形时，两种情况可能同时存在，但在1例男孩中，膀胱重复畸形与矢状面的4条尿道相关联。5例患者的膀胱是相连的；2例患者中，切除了一个膀胱。6例患者的结果令人满意，1例患者膀胱无法排空。导致重复畸形的基本缺陷尚不清楚。这些情况的几个特征表明每种类型都有不同的病因。与膀胱外翻-尿道上裂综合征有相似之处。即使其他系统存在严重异常，总体和泌尿系统预后也良好。
