Summary
The ability of sildenafil to aid in the return of erections after nerve-sparing radical
prostatectomy has been established. Patients who had either one or both neurovascular bundles
spared demonstrated dramatically better responses to "as needed" sildenafil than those that
did not, and a positive erectile response to sildenafil was only seen in patients in whom at
least one NVB was spared. This study has been designed to determine if sildenafil taken
nightly works better than sildenafil on as "as needed" basis for the return of erectile
function. The investigators hypothesis is that sildenafil taken nightly promotes a more rapid
return of erectile function after nerve-sparing laparoscopic radical prostatectomy.
