Long Term Follow-up for Hypospadias

Study Overview
=================
Brief Summary
-----------------
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.

| Testicular ultrasonography | The investigator will ask a testicular ultrasonography which will be performed by a radiologist, the following data will be collected: testicular volume, aspect of the testicular parenchyma. | day 0 | 
| puberty clinical signs | The investigator will use the tanner's criteria during the physical examination. Stages of genital [G] and pubic hair [Ph] development in the male. G-1, Ph-1: pre-pubertal; G-2: the testis and scrotum enlarge, and the skin of the scrotum shows some reddening and change in the texture. Sparse growth of pigmented hair usually slightly curly, mainly at the base of the penis (Ph-2); G-3: Testis and scrotum enlarge further, the penis grows mainly in length but also in breadth. The hair is darker, coarser and curlier and spreads over the junction of the pubes (Ph-3); G-4: Scrotum, testis, and penis grow further with development of the glans, and further darkening of the scrotal skin. The hair spreads covering the pubes; G-5: adult stage with spreading of the hair to the medial surface of the thighs (Ph-5). | Day 0 | 
| endocrine disorder |  | Day 0 | 
| patient satisfaction | The investigator will do an interrogation of the patient about his personal satisfaction, the response will be yes or no. | day 0 |
