The dorsal lamina of the rectus sheath: a suitable grafting material for the penile tunica albuginea in Peyronie's disease?
OBJECTIVE
To estimate the morphological suitability of human connective tissue structures from different regions as graft material in Peyronie's disease, and to present preliminary results from 12 patients with grafting of corporal bodies using autologous rectus sheath.


METHODS
In five male cadavers the penile tunica albuginea was compared with the dorsal lamina of the rectus sheath, the palmar aponeurosis, the iliotibial tract and the Achilles tendon by using histological sections stained with haematoxylin and eosin, Crossmon's trichrome stain and resorcin-fuchsin. Surgical results and complication rates were investigated in 12 patients with Peyronie's disease after grafting the corporal bodies with autologous rectus sheath to correct their penile curvature.


RESULTS
On histology, the penile tunica albuginea showed a three-dimensional meshwork of collagenous and elastic fibres. The dorsal lamina of the rectus sheath had a remarkably similar fibre structure. The other tissues had a different histology, with long collagenous fibres in parallel orientation and elastic fibres restricted to the loose connective tissue around blood vessels and nerves. Clinically, the penile deviation was successfully corrected in 10 patients; there were two residual deviations (15 degrees and 35 degrees ). There were minor complications after surgery in six patients, not requiring surgery.


CONCLUSIONS
The dorsal lamina of the rectus sheath has similar morphological characteristics to the tunica albuginea, and therefore represents an ideal autologous graft; the first clinical results are promising.
