Advances in the Management of Post-Radical Prostatectomy Erectile Dysfunction: Treatment Strategies When PDE-5 Inhibitors Don't Work.

Phosphodiesterase type-5 (PDE-5) inhibitors have revolutionized the treatment of post-radical prostatectomy erectile dysfunction. For those patients who undergo a non-nerve-sparing radical prostatectomy or whose condition fails to respond to PDE-5 inhibitors, alternative treatment with intracavernous injection therapy, transurethral alprostadil, vacuum erection devices, and recently described combination therapy is available. The goals of therapy are to provide the patient with a means of obtaining an erection so that the patient and his partner may resume sexual relations as soon as possible following radical prostatectomy. There is evidence that early institution of treatment may promote improvement in the return of spontaneous erections in patients who have undergone nerve preservation. In patients who undergo non-nerve-sparing procedures, therapy may improve penile rigidity. Intracavernous injection therapy, transurethral alprostadil, and vacuum devices are highly effective in the management of post-prostatectomy erectile dysfunction. High dropout rates, which are not related to adverse effects, have been described with all 3 modalities. Pre- and postoperative counseling may improve patient and partner satisfaction.
