Objectives: The insertion of a penile prosthesis (PP) provides an acceptable, definitive solution for erectile dysfunction (ED) and has the highest patient satisfaction rate among other treatment choices. PP surgery is an elective procedure performed to re-establish sexual function and improve quality of life, patient perceived satisfaction is the primary goal. Studies suggest that vacuum erection device (VED) can assist in penile rehabilitation and can prevent penile shrinkage in both length and girth in patients. We aimed to examine the outcomes of using VED for one month prior to PP implantation surgery in our patient population to evaluate changes in pre-operative penile length and the benefits associated with surgical ease and outcomes. 

Material and Methods; Fifty-one patients requesting PP implantation for ED were randomized to either pre-operative VED use for 10-15 minutes a day for at least thirty days (VED group; n=25), or as the control group (non-VED group; n=26). Baseline and on day of surgery stretched penile lengths (SPL) were recorded by an individual blinded to treatment assignments. Subjective analysis of the ease of corporal dilatation was provided with the surgeons performing the implant. 
Results: Baseline dorsal SPL measurements were 10.71±1.28cm and 10.87±1.26cm in the VED and non-VED groups, respectively. On the day of surgery dorsal SPL measurements were 11.50±1.33cm and 11.06±1.34cm in the VED and non-VED groups, respectively. Compared to the non-VED group, the mean value of VED group’s dorsal SPL significantly increased an average of 0.79cm (p <0.05). Additionally, smoother corporal dilatation after use of VED. 
Conclusions: The daily use of a VED during the month prior to PP implantation surgery significantly increases pre-operative penile length and as a result, allows for easier corporal dilatation intraoperatively.
