Vasculogenic erectile dysfunction.
The ability to get an erection relies on increased blood flow to the penis, a process mediated by hormones, nerves, higher brain centres and blood vessels/vasculature. Normally this increased filling obstructs venous outflow causing build-up of blood in the erectile tissue of the penis resulting in an erection.
Throughout the body, healthy blood vessels are able to dilate in response to chemical signals increasing blood flow to the tissues they supply. Vascular dysfunction arises when blood vessels lose the ability to dilate and is associated with a variety of pathologies linked through this common mechanism. Vascular dysfunction causes heart disease, peripheral artery disease and erectile dysfunction. It is associated with conditions like diabetes, hypertension and high cholesterol.
Renova linear shockwave therapy.
Linear shockwave therapy (LWST) is a new, non-invasive therapy for this kind of erectile dysfunction. Using low intensity shockwaves, the treatment attempts to stimulate the lining of blood vessels to repair itself, reversing vascular dysfunction and increasing blood flow to the erectile tissue.
Shockwaves are applied along the length of the penis.
Treatment is delivered once a week for 4 -5 weeks in the outpatient clinic in Hornsby. No sedation is required.
The machine is positioned at four points on the right and left of the penis and the treatment applied four times in one session, taking a total of around 40 minutes.
No sedation is required and the treatment is pain free.
LSWT is ideal for men with vasculogenic erectile dysfunction for whom PDE-5 inhibitors are ineffective or contraindicated.
Preliminary clinical data show that LSWT is effective in roughly 70% of men, whether they respond to PDE-5 inhibitors or not.
Sexual dysfunction after prostate cancer treatment.
Renova is a treatment for vasculogenic erectile dysfunction. After radical prostatectomy, the primary cause of ED is neurogenic, and Renova is not an appropriate management option. Men with erectile dysfunction following radical prostatectomy do have many treatment options.
Currently shockwave therapy is not a verifiable treatment and success is by no means certain.
