Peyronie's disease is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis. Specifically, scar tissue forms in the tunica albuginea, the thick sheath of tissue surrounding the corpora cavernosa, causing pain, abnormal curvature, erectile dysfunction, indentation, loss of girth and shortening. A variety of treatments have been used, but few have been especially effective.
|Synonyms||Peyronie disease, induratio penis plastica (IPP), chronic inflammation of the tunica albuginea (CITA)|
|Frequency||~10% of men|
Signs and symptomsEdit
A certain degree of curvature of the penis is considered normal, as many men are born with this benign condition, commonly referred to as congenital curvature.
The disease may cause pain; hardened, big, cord-like lesions (scar tissue known as "plaques"); or abnormal curvature of the penis when erect due to chronic inflammation of the tunica albuginea (CITA). Although the popular conception of Peyronie's disease is that it always involves curvature of the penis, the scar tissue sometimes causes divots or indentations rather than curvature. The condition may also make sexual intercourse painful and/or difficult, though it is unclear whether some men report satisfactory or unsatisfactory intercourse in spite of the disorder. It can affect men of any race and age. The disorder is confined to the penis, although a substantial number of men with Peyronie's exhibit concurrent connective tissue disorders in the hand, and to a lesser degree, in the feet. About 30 percent of men with Peyronie's disease develop fibrosis in other elastic tissues of the body, such as on the hand or foot, including Dupuytren's contracture of the hand. An increased incidence in genetically related males suggests a genetic component.
The underlying cause of Peyronie's disease is not well understood. The most common cause is a buildup of plaque inside the penis. It could be by trauma or injury to the penis usually through sexual intercourse or physical activity, although many patients are often unaware of any traumatic event or injury.[medical citation needed]
A urologist may be able to diagnose the disease and suggest treatment. An ultrasound can provide conclusive evidence of Peyronie's disease, ruling out congenital curvature or other disorders.
Medication and supplementsEdit
Collagenase clostridium histolyticum (Auxilium), a drug originally approved by the FDA to treat Dupuytren's contracture, is now an FDA-approved injectable drug for treatment of Peyronie's disease. The drug is reported to work by breaking down the excess collagen in the penis that causes Peyronie's disease.
Surgery, such as the "Nesbit operation" (which is named after Reed M. Nesbit (1898–1979), an American urologist at University of Michigan), is considered a last resort and should only be performed by highly skilled urological surgeons knowledgeable in specialized corrective surgical techniques. A penile prosthesis may be appropriate in advanced cases.
Physical therapy and devicesEdit
There is moderate evidence that penile traction therapy is a well-tolerated, minimally invasive treatment, but there is uncertainty about the optimal duration of stretching per day and per course of treatment, and the treatment course is difficult.
Peyronie's disease can be a physically and psychologically devastating disease. While most men will continue to be able to have sexual relations, they are likely to experience some degree of deformity and erectile dysfunction in the wake of the disease process. It is not uncommon for men afflicted with Peyronie's disease to exhibit depression or withdrawal from their sexual partners.
