Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are men over 40 with localized prostate cancer who are scheduled for nerve-sparing prostatectomy and have mild erectile dysfunction.
✕Probably not a fit
Patients with moderate to severe erectile dysfunction or those who have had prior pelvic or penile surgery may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study investigates the effectiveness of vibroelastography, a noninvasive ultrasound technique, in evaluating tissue fibrosis alongside standard penile duplex Doppler ultrasound to assess erectile function recovery in patients who have undergone radical prostatectomy for prostate cancer. The goal is to determine if this combined approach provides additional insights into erectile dysfunction recovery. Participants will be monitored for their erectile function post-surgery to evaluate the utility of this method.
Why it matters
Potential benefit: If successful, this study could improve the assessment and management of erectile dysfunction in men recovering from prostate cancer surgery.
How similar studies have gone: While the use of ultrasound techniques in assessing erectile function is established, the specific combination of vibroelastography with standard methods is relatively novel and has not been extensively tested.
