abstract: Hypospadias is a hypoplasia of the tissues forming the ventral side of the penis responsible of an ectopic meatus of the urethra. This congenital anomaly results in a fusion defect of the two epithelial surfaces of the urethral groove between the 11th and the 18th weeks of development. The earlier this process arrests, the more the form is proximal and severe. This is the second genital malformation in boys with 1 case per 250 male births. Its origin is often multifactorial (genetic, endocrine, placental and environmental). Three anatomical forms exist: proximal, middle and distal (the most common). Additional exams (endocrine, genetic and morphological) are realized early, before surgery, in case of severe hypospadias, familial, associated with cryptorchidism, bifid scrotum, micropenis and/or skeletal, kidney, and/or heart abnormalities. It clarifies pubertal prognosis. The surgical management is made between 6months and 12months: it limits the functional and aesthetic impact of this malformation. Many surgical techniques are described. They all have in common the three operating time: penile straightening, urethroplasty, reconstruction of the ventral side of penis. They are based on direct sutures, local flaps pedicled, and grafts (skin or mucosa). The rate of postoperative complications is between 6 and 30 %. The two main complications are fistulae and stenoses. The psychological follow-up of these children is necessary to adulthood. Surgery of hypospadias remains a delicate surgery and must be performed by experienced surgeons.
