[Vardenafil for the treatment of men with erectile dysfunction after radical retropubic prostatectomy]
1Department of Urology, Renji Hospital of Shanghai Second Medical University, Shanghai 200127, China.
Abstract:
More than one-third of men may experience erectile dysfunction (ED) after nerve-sparing radical retropubic prostatectomy. A recent study has shown that vardenafil, a phosphodiesterase 5 inhibitor, could significantly improve the key indices of erectile function in men after unilateral or bilateral nerve-sparing radical retropubic prostatectomy. Few adverse events were observed in the study.
