[Surgical treatments of erectile impotence].
Impotence affects 10 to 15% of the male population. Organic factors are recognized in 80% of cases. Intracavernosal injections of vasoactive agents (Virag) have provided advances in the physiopathologic understanding of impotence and provide new ways of treating this incapacity. However this option is inaffective in most organic cases: arteriogenic, venogenic or disorders of smooth cavernous muscle. Vasoactive injections for many reasons are abandoned in about 40% of the cases. Two kinds of surgical management can be performed: microrevascularization in order to restore the arterial penile flow or to reduce penile venous flow during erection; implantation of penile prosthesis when other therapeutic possibilities are exhausted. Arterialization of the deep dorsal vein (DDV) appears to be the best procedure in arteriogenic and principally venous impotence. Erectile function in theses case is restored in 60% of our patients. Two types of prostheses can be implanted: semi-rigid with an axial permanent rigidity and inflatable or hydraulic devices with a flaccid aspect after intercourse. These prostheses are technically successful in 75 to 90% of cases, but partner satisfaction does not match surgical success rates.
