Hypospadias is one of the most common .abnormalities of the external male genitalia but is very difficult to repair. Hypospadias reoperation is also a common practice for pediatric urologists, though repair of hypospadias at reoperation is much more difficult. The surgical technique involves using the well-vascularized ventral penile skin strip as a neourethral plate, and choosing surgical procedures according to the penile conditions. Tubularized incised plate urethroplasty （TIP）, first presented by Snodgrass in 1994, is widely accepted due to the ease of operation and satisfactory postoperative penis appearance. It can be used in most primary hypospadias cases, as well as in reoperations following failed surgery. Many satisfactory results of TIP have been reported in failed hypospadias repair. In this study, we used TIP and the Duplay technique for failed hypospadias repair in patients with the same penile conditions, and obtained similar, satisfactory results with both methods. Under suitable conditions, it is preferable to use a well-vascularized flap to repair failed hypospadias cases, and we therefore performed some Onlay island flap urethroplasties with good results.
