Impotence | Can Hyperbaric Oxygen Improve Erectile Function Following Surgery for Prostate Cancer

Impotence research study

What is the primary objective of this study?

The purpose of this study is to determine if adding hyperbaric oxygen therapy, a therapy that delivers oxygen under slight pressure, to a drug treatment of PDE5I (such as Viagra, Levitra, Cialis)for men following surgery for prostate cancer will result in more men being able to continue to have erections.

Who is eligible to participate?

Inclusion Criteria: - male - age 40-69 - diagnosis of Stage I prostate cancer - bilateral NSRRP as primary treatment - sexual potency prior to surgery Exclusion Criteria: - COPD, CHF, diabetes mellitus - known inability to tolerate PDE5I - confinement anxiety/claustrophobia - planned adjuvant or neo-adjuvant therapy - patients taking alpha blockers or nitrates - patients with retinitis pigmentosa

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Impotence

Prostatic Neoplasms

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Sildenafil therapy plus post-NSRRP HBO2TSildenafil (Viagra) 50 mg - PO QHS for 12 months beginning the first evening they return home from surgical hospital stay PLUS Post-NSRRP hyperbaric oxygen therapy (90 minutes of 100% oxygen at 2.2ATA (equivalent to the pressure exerted at a depth of approximately 40 feet below sea level). There will be 5 or 10 treatments. The full treatment cycle will be completed within 2 weeks.

Drug:Sildenafil therapy plus sham post-NSRRP HBO2TSildenafil (Viagra)50 mg - PO QHS for 12 months beginning the first evening they return home from surgical hospital stay PLUS Post-NSRRP sham hyperbaric oxygen therapy - 90 minutes at 2.2ATA but instead of 100% oxygen, they will receive air administered via the oxygen hoods, as if they were being administered oxygen. Participants in this group will receive 5 or 10 sham treatment sessions. Full treatment cycle will be completed within 2 weeks.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
