Effect of Nightly Versus Prn Sildenafil on Early Return of Erectile Function Following Laparoscopic Radical Prostatectomy

• Status: Completed
• Trial end date: 2008-10-01
• Target enrollment: 0
• Participant gender: Male

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.
