Is this trial a fit for you?

Likely a good fit

Ideal candidates are sexually active men over 18 who are potent and scheduled for nerve-sparing prostate surgery.

Probably not a fit

Patients who are candidates for salvage surgery, on androgen deprivation therapy, or for whom PDE5 inhibitors are contraindicated may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of robotic-assisted radical prostatectomy (RALP) combined with saline-assisted fascial engorgement (SAFE) to improve outcomes for men with localized prostate cancer. The study utilizes advanced micro-ultrasound technology to enhance nerve-sparing techniques during surgery, potentially reducing the risk of erectile dysfunction and urinary incontinence post-operation. Participants will be men over 18 who are sexually active and planned for nerve-sparing surgery. The trial aims to balance effective cancer removal with the preservation of sexual function.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of erectile dysfunction and urinary incontinence in men undergoing prostate surgery.

How similar studies have gone: Previous studies have shown promising results with nerve-sparing techniques and hydrodissection, suggesting potential success for this novel approach.
