T-incision technique in distal hypospadias: a modification of meatal advancement and glanuloplasty.

Abstract

Hypospadias is among the most common of the congenital anomalies. Distal hypospadias refers to an orifice in the distal third of the penile shaft. Correction of distal hypospadias requires different techniques, depending on the location of the meatus. Simple advancement techniques can be used for most distal hypospadias, whereas hypospadias with chordee requires reconstruction of a urethra. The meatoplasty and glanuloplasty procedures developed by Duckett have become standard operations to correct these lesions. Complications such as meatal stenosis, meatal retraction, and fish mouth-like meatus can be seen after meatal advancement and glanuloplasty ("MAGPI"), though it usually yields good results. In an attempt to avoid the complications associated with the meatal advancement and glanuloplasty procedure, the authors added a modification to the procedure for those hypospadias cases located in the coronal sulcus or its distal part. As an addition to conventional meatal advancement and glanuloplasty, a transverse incision on top of the vertical incision was made so that the urethra was supported by lateral triangle flaps created on the glans. Lateral triangle flaps of the glans were sutured to the dorsal aspect of the urethra advanced from the previous position. Thus, stress on the urethra was lessened and meatal retraction was prevented. When closure was performed with a T incision, an M-shaped, zigzag incision line was placed instead of a circular incision line. Therefore, stenosis was prevented and a vertical meatus with good cosmetic appearance was obtained. Fifty-three boys aged 4 to 7 years were operated on with this technique and were followed for 2.4 years. Good functional and cosmetic results were achieved in most of the cases.
