[Flexible penile implants. An experience over 60 cases].

The author proposes flexible silicone elastomer penile prostheses or implants to restore erectile function. They have the advantage of being flexible, adjustable during the operation and they can be elongated by traction and are resistant to axial pressure. The surgical incisions are explained, in particular the penopubic approach, together with insertion of the implants accompanied by cavernopublic disinsertion and recentering of the glans in patients with La Peyronie's disease. Sixty patients were operated and reviewed with a follow-up of 8 months to 4 years. There were no cases of infection of rejection. 85% of patients were satisfied with the quality of their erectile function. The haemodynamic mechanisms of impotence, situated either in the corpora cavernosa or in the peripheral venous plexus, are reviewed. Flexible penile implants allow restoration of erectile function via various combinations of three possible mechanisms: reduction of the free cavernosal volume, increased resistance to venous drainage, and increased intracavernosal pressure.

[Flexible penile implants in the restoration of erectile function].

Flexible penile implants not only allow sexual penetration due to their physical properties, but also frequently induce restoration of real erection due to the reduction of the venous bed with preservation of the cavernous arteries. The author reports a series of 53 penile implant insertions. Restoration of erection above the horizontal was observed in 60% of cases with good tumescence of the glans.

[A biomechanical study of flexible penile implants].

The prostheses used are silicone elastomer flexible penile implants. They are not hard, but flexible and capable of being elongated without traction. These implants have the advantage of resisting axial pressure which facilitates intromission, even in the absence of erection. Their flexibility also allows the penis to hang when the patient is standing. For the penis to hang normally, it must be sufficiently long (hence the value of cavernopubic release) and the intracavernous cavity must be longer than the prosthesis. The prosthesis does not alter the cavernous artery, but markedly flattens the venous plexus (lakes and efferent veins).

[Cavernoscopy: indications and initial results].

Up to date general tendency in diagnostic procedure is to check the pathology directly under vision. In all sciences technology has provided means of investigation with high resolution, which can detect alterations of few millimeters in size. However the direct vision of the disease is always preferred by the physician. In this program Cavernoscopy is perfectly inserted as the andrologist expected an examination able to provide direct informations on erectile tissue under physiological and pathological points of view. Cavernoscopy is simple, repeatable, atraumatic and effective in its purposes and even if it requires a minimum of training its practice is to be recommended because the direct vision of erectile tissue is surely the first step towards operative performances inside corpus cavernosum.

Surgical treatment of Peyronie's disease using penile implants: survey of 69 patients.

Implantation of bilateral prostheses was used to treat Peyronie's disease in 69 patients. A circumferential approach was used in 46 patients and, more recently, a prepubic approach was used in 23. In addition, plaque removal was performed by a transcavernous route in 29 patients. Penile lengthening was performed in 49 patients and the glans was repositioned in 14. In 4 patients it became necessary to remove the implants. The best results without complications were observed when the prepubic approach was used for implants and lengthening of the penis, without removal of the plaque. This technique provides a penile length gain of about 3 cm. and generally does not obviate additional normal erection.
