[Hypospadias in the female]

Female hypospadias is a rare, but well defined anomaly of the lower urogenital system. From an embryologic point of view it represents an arrest during a late stage of sinus urogenitalis development. It is not to be confused with minor variants of the external urethral meatus of a doubtful clinical relevance. The main symptom is a severe subvesical obstruction, and usually it presents early in infancy. A case is presented, in which on the basis of the incorrect diagnosis of "occult neurogenic bladder outlet obstruction" a supravesical diversion (ileal conduit) was done. Undiversion was successfully carried out at an age of 7 years.
