Distal Penile Hypospadias
Hypospadias is a congenital defect due to incomplete tubularization or fusion of the urethral plate, leading to abnormal location of the meatus anywhere along the ventral aspect of penile shaft and down on to the perineum.[1] Hypospadias are classified into anterior (distal), middle, and posterior (proximal) according to site of native meatus. The incidence of anterior hypospadias is 71%, middle 16%, and posterior 13%.[2] Procedures established to correct distal penile hypospadias are the tubularized incised plate urethroplasty (TIP repair), Thiersch–Duplay, Mathieu’s repair, Mustarde, Onlay flap, and meatal advancement and glanduloplasty (MAGPI). Of these procedures, Mathieu’s and TIP urethroplasty (Snodgrass repair) have been widely practiced. |
