To determine if penile length in men after exstrophy reconstruction is short because of a congenital defect in the size of the corpora cavernosa.

Materials and Methods

Pelvic MRI scans of ten men who underwent exstrophy reconstruction as children and ten age and race matched controls were performed and measurements of penile and pelvic anatomy were compared.


The length of the corpora cavernosa in men after exstrophy reconstruction is shorter than normal. Dividing total corporal length into an anterior and posterior segment reveals that the anterior segment is short but that the posterior segment, attached to the pubic ramus, is normal. However, the diameter of the posterior corporal segment is greater than in controls. Although diastasis of the symphysis pubis increases the intersymphyseal and intercorporal distances, the angle between the corpora cavernosa is unchanged, presumably because the corporal bodies are separated in a parallel fashion.


The penis in men after exstrophy reconstruction is short, at least in part due to a congenital deficiency of corporal tissue. Since diastasis of the pubic symphysis and chordee reduce penile visibility, approximation of the pubic symphysis and procedures to straighten the penis may improve its cosmetic appearance. However, because the corpora cavernosa are short, penile length in men after exstrophy reconstruction will always be shorter than normal.
