Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hypospadias is a frequent malformation. The definition of hypospadias is a ventral tissues hypoplasia, with an abnormal position of the urethral meatus, a chordee of the penis and an open foreskin. It can be associate with other genital malformation; in that case it can be classified in the wider field of the disorder of sex development (DSD). There is a lot of surgical technics for those malformations.

In the pediatric surgical department, in Lyon, three technics are the most used because of their reliability and their good outcomes in short and mid term.

This is essential for investigator to have a long term evaluation, with a physical exam and paraclinical exams, after the puberty, to assess the outcomes after the changes especially at the puberty.
