Penile Length Maintenance Post-Prostatectomy

The treatment of prostate cancer results in several known sexual dysfunctions, including
erectile dysfunction, orgasmic dysfunction, ejaculatory dysfunction, penile curvature
(Peyronie's disease), and reduced penile length. Among the dysfunctions, loss of penile
length is often one that results in significant distress and bother to patients. Beyond the
esthetic concerns, reduced penile length may lead to inability to participate in sexual
intercourse, difficulty with future interventions to restore erectile function, and lead to
worsened urinary hygiene.

Penile traction therapy (PTT) is currently the best available treatment to maintain or
restore lost penile length due to conditions that reduce length. To date, no studies have
evaluated the benefits of using PTT in this clinical setting. The objective of the current
study is to evaluate the efficacy of a novel penile traction device (RestoreX®), created and
funded through Mayo Ventures, in maintaining or restoring reduced penile length.

To accomplish the study, a population of men from Mayo Clinic who have undergone a
prostatectomy will be enrolled and randomized to utilize the device for varying amounts of
time. Outcomes will be assessed at 6 and 9 months post-prostatectomy and results are to be
used with the intent to publish in a scientific journal.
