[Anatomical and embryological study of a case of bladder exstrophy with duplication of the urethra]

An exceptional case of a double urethra associated with an extrophied bladder in a neonate boy is reported. This particular malformation allows an ideal procedure with the recovery of a good continence. After the anatomic study of the anomalies, the authors try to find an embryologic explanation. The usual theories of the development in the cloacal region are discussed. Only the embryologenesis as described by SOLERE can explain this malformation.
