Hypospadias is a relatively common congenital malformation that manifests as a more inferior position of the external urethral opening than normal and can be located anywhere between the coronal sulcus of the penis and the perineum. It is often accompanied by other malformations of the external genitalia such as ventral curvature of the penis, dorsal scalpel-like accumulation of the foreskin, and cryptorchidism. The treatment of hypospadias relies mainly on surgery, including phase I treatment and phase II treatment. Generally speaking, for patients with good local skin conditions of the penis, penile curvature that can be corrected at the same time, and urethral defects that are not particularly long, stage I hypospadias correction surgery can be performed. One-stage surgery is less painful for patients and faster recovery, which is the mainstream direction for the treatment of hypospadias at present. However, staged surgery also has its relative indications for patients with perineal type, penile scrotal type, poor local skin condition of the penis or long defect after penile extension. Depending on the different tissue repair materials used, it is divided into local penile scrotal tipped flaps and free grafts (such as oral mucosa and bladder mucosa) repair. The main goal of hypospadias surgery is to achieve standing orthostatic urination, correction of penile curvature deformity and certain aesthetic appearance of the external genitalia. Since hypospadias has different subtypes, the degree of penile curvature and the local penile skin and urethral orifice vary from patient to patient, the best surgical plan for each patient needs to be tailored to his or her condition.
