About this trial
This is an interventional health services research trial for Prostate Adenocarcinoma focused on measuring Radical Prostatectomy
Eligibility Criteria
Inclusion criteria include:
- Age > 40 years
- Clinically localized prostate cancer (American Urological Association Grade Groups 1-2; cT1c or cT2a-b; PSA < 10) without clinic or imaging evidence of localized extra-prostatic or metastatic disease (i.e. AUA low and favorable intermediate risk prostate cancer)
- International Index of Erectile Function (IIEF) of ≥ 21 points at baseline (no or mild erectile dysfunction)
- Patient-expressed interest in consultation for sexual function (erectile function) preservation/ optimization
- Planned bilateral nerves-paring prostatectomy
Exclusion criteria include:
- Moderate or severe ED based in IIEF criteria (score < 21)
- History of prior pelvic or penile surgery
- Current or prior androgen deprivation therapy
- Planned non-nerve sparing prostatectomy
Sites / Locations
- Mayo Clinic in Rochester

5. Study Description
Brief Summary
Researchers are trying to determine whether there is additional utility to using vibroelastography, a noninvasive ultrasound technique to evaluate for the presence of tissue fibrosis, in conjunction with standard penile duplex Doppler ultrasound to assess erectile function (recovery) after prostate cancer surgery.
