The Use of Ultrasound in Assessing Post-prostatectomy Erectile Dysfunction

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

Ulrasound Vibroelastography (UVE)

Diagnostic Test

Ultrasound technique to quantitatively assess tissue stiffness (elasticity and viscosity) by applying vibration through a specialized probe (indenter).

Primary outcomes

Change in Viscoelasticity

Time frame: Baseline, 3 months, 6 months and 9 months post-prostatectomy

As measured by Ultrasound Vibroelastography (UVE)
