Treatment of erectile dysfunction after radical retropubic prostatectomy with PDE5 inhibitor
Abstract
The rate of erectile dysfunction after radical retropubic prostatectomy is from 10% to 100%. The prevalence of erectile dysfunction after nerve-sparing radical prostatectomy is more than one third. In the patients who had undergone bilateral NS, 72% responded to sildenafil, 71.7% and 59.7% responded to 20 mg and 10 mg of vardenafil respectively. For all randomized patients who received tadalafil, the mean percentage of successful penetration attempts was 54% and the mean percentage of successful intercourse attempts was 41%. For the subgroup with evidence of postoperative tumescence these values were 69% and 52%, respectively. No head-to-head trials have been performed with sildenafil, vardenafil and tadalafil in treatment of erectile dysfunction after radical prostatectomy.
