Analysis of Technique Comparison With a Vacuum Erection Device as Part of an Erectile Rehabilitation Program Following Robotic Radical Prostatectomy: A Randomized Comparison of Methodology
The purpose of this study is to determine which technique in using a vacuum erection device
(VED) is best. Erectile dysfunction (ED) after robotic prostate cancer surgery is a concern
for both the surgeon and the patient. Recent studies have shown that beginning to use the
vacuum pump on a daily basis starting with in 2-8 weeks may help prevent the start of penile
shrinkage. This is a potential issue that can occur because of decreased blood flow after
prostate cancer surgery. This study will allow researchers to determine and compare vacuum
therapy techniques and erectile function outcomes of patients who have prostate cancer
surgery

PRIMARY OBJECTIVES:
I. Determine sexual function and penile morphometric outcomes for the post-robotic-assisted
laparoscopic prostatectomy (RALP) patients undergoing daily vacuum therapy using one of two
randomized methods and whether these outcomes differ.
SECONDARY OBJECTIVES:
I. Compare compliance rates between the two randomized groups using the compliance
questionnaire and a diary collected from patients at each follow up visit.
II. Compare overall patient satisfaction with the recovery procedure between the two
randomized groups utilizing the SHIM (Sexual Health Inventory for Men) questionnaire.
OUTLINE: Patients are randomized to 1 of 2 treatment groups.
GROUP A: Patients receive vacuum therapy daily over 10 minutes while holding erection for 2
minutes after undergoing RALP. Patients complete erection process 5 times.
GROUP B: Patients receive vacuum therapy daily over 10 minutes while holding erection for 5
minutes after undergoing RALP. Patients complete erection process 2 times.
After completion of study treatment, patients are followed up at 3, 6, and 12 months.
