Changes in Penile Firmness With Low-Intensity Shockwave Therapy (LiST)

Patients presenting with erectile dysfunction are often found to have increased corporal firmness on elastography. We hypothesize that this corporal firmness reflects reversable changes that can be altered by Low-Intensity Shockwave Therapy (LiST). In this pilot study patients found to have increased corporal firmness will be treated with LiST.
