[Duplication of the bladder by a frontal septum. Apropos of a case]

The authors report a case of total bladder duplication by frontal septum. The anterior bladder was functional. The posterior bladder was non-functional, and drained a destroyed kidney. Analysis of the rare cases reported in the literature suggests that this malformation should be differentiated from other bladder duplications, because it may be a giant ureterocele. In conclusion, the authors stress the simplicity of the management, consisting of resection of the septum and nephrectomy of the non-functional kidney.
