Abstract
|
|
|
Intracavernous (IC) injection therapy of vasoactive agents is now being widely choser as the first armamentarium for the treatment of male erectile dysfunction, nevertheless, has a troublesome problems due to the drug delivery vehicle with
needle.
Therefore, the less invasive route of drug administration has been needed. We investigated the efficacy and safety of intraurethral (IU) instillation of lyposomal prostaglandin E1 on the induction of penile erection. Thirty patients with male
erectile
dysfunction were enrolled in a prospective study. Overall, 73.3% of cases were responded with 33.3% of full erection and 40% of partial erection after IU instillation. IU self-instillation at home was more effective than at clinic on the
induction
of
penile erection. It is somewhat effective in cases of diabetogenic, psychogenic, neurogenic and mild vasculogenic erectile dysfunction but much less effective in severe vasculogenic and cavernosal disease. Interval of onset and duration of
erection
were
delayed and shortened in IU instillation rather than IC injection. Side effect were mild and transient urethral pain with the most frequent incidence and followed by transient hypotension in less.
In conclusion, intraurethral instillation of lyposomal prostaglandin E1 can be selected as one of therapeutic modality to restore the penile erection for some limited patients with erectile dysfunction to want to select a less invasive treatment
alternative.
