at the Brady Urological Institute offer a comprehensive range of
diagnostic techniques and treatment therapies for erectile dysfunction
(ED), as well as for Peyronie's disease, premature ejaculation,
priapism, and orgasmic dysfunctions. Treatments are tailored to
meet each patient's psychological and physical needs and preferences.
Penile prosthesis implantation has the highest satisfaction rate
of all treatment options for ED and Johns Hopkins urological surgeons
perform well over 60 of these procedures annually. Some individuals
require arterial or venous microsurgery due to serious pelvic trauma
or venous leakage, and our experts regularly perform these specialized
Arthur L. Burnett II, M.D., Director
of the Male Reconstructive Clinic at the Brady Urological Institute,
played a pivotal role in initial ED research efforts, describing
nitric oxide and its important role in triggering erections. Release
of NO between nerve cells causes blood vessels in the penis to dilate,
increasing the volume of blood flowing into the penis and causing
it to enlarge. This scientific foundation led to the eventual development
of the oral PDE5 inhibitors that have revolutionized ED therapy
in the last several years.
A key area of research by our
experts is the underlying causes and mechanisms of priapism, a "forgotten"
yet devastating penile erection disorder that affects many men.
Dr. Burnett performed the original science on new ways to treat
this condition, and his research was recently published in Urology.
Dr. Burnett reported that PDE5 inhibitors might offer a solution
to the management of recurrent priapism episodes.
Johns Hopkins urological researchers
continue with their efforts to discover the causes of ED. Current
interventions are being aimed directly at protecting the erectogenic
nerves that are often damaged by radical prostatectomy surgery.
New agents under development are being tested at Johns Hopkins to
see if they can help men recover nerve function quickly after their
