Effect of radical retropubic prostatectomy on erectile function, evaluated before and after surgery using colour Doppler ultrasonography and nocturnal penile tumescence monitoring

Abstract

From objective tests of erectile function on patients scheduled to undergo radical prostatectomy, 17% had normal erectile function. However, even after nerve-sparing radical retropubic prostatectomy, the proportion retaining potency was unsatisfactory. Although a neurological disorder was the main cause of erectile dysfunction after surgery, vascular disorders were also important.
