ARTERIOVENOUS-FISTULA COMBINED WITH BASAL EXTERNAL PENILE COMPRESSION- A NEW CURE FOR MALE IMPORTANCE

We describe here a new procedure designed to enable reproducible susta ined erection in a canine model, In 10 dogs, an end-to-side arterioven ous fistula was created between the inferior epigastric artery and dee p dorsal vein, A chronic skin tunnel was created at the penile base. B lood flow, intracavernosal pressure and intraspongiosal pressure and b lood gases were measured initially and 3 months later. Cuff applicatio n for 30 minutes was used daily, At 3 months, animals were sacrificed and biopsies obtained. Physiologic and histological parameters of erec tile structures remained unchanged. Intracavernosal and intraspongiosa l pressures increased to 33.7 +/- 6.7 mm Hg and 25.3 ,3 +/- 12.2 mm Hg (from 8.0 +/- 2.9 and 6.0 +/- 3.6 mm Hg) after cuff application. We c onclude that sustained erections are feasible, This procedure appears safe for human trials.
