Peyronie's disease(redirected from curvature of penis)
Peyronie's disease is a condition characterized by a bent penis.
The cause of Peyronie's disease is unknown and the disease is often difficult to treat. For some reason, a thick scar develops in the penis and bends it. Almost a third of patients with Peyronie's disease also have similar contracting scars on their hands, a disease called Dupuytren's contractures. Some cases are associated with diabetes, and others appear after prostate surgery. Because prostate surgery always requires a catheter in the bladder, there is some suspicion that catheters can cause the scarring. However, many cases of Peyronie's disease arise without any use of a catheter. There is also a congenital form of penile deviation, again with no known cause. Most of the scars are located in the mid-line, therefore most of the angulations are either up or down.
Causes and symptoms
Peyronie's disease occurs in about 1% of men, most of them between 45-60 years old. Although there is no good research data to back it up, the suspicion exists that Peyronie's disease is the result of injury. If not a catheter, then sudden, forceful bending during sexual intercourse could easily tear the supporting tissues and lead to scarring.
The symptom is bending of an erect penis, sometimes with pain. It often interferes with sexual intercourse. Erectile failure associated with the angulation often precedes it.
Attempts have been made to reduce the angulation with injections of cortisone-like drugs directly into the scar, but they are rarely successful. Surgery seems to be the better answer. After the scar is removed, plastic repair of the penis is attempted, often with a graft of tissue from somewhere else on the body. The Nesbit procedure is one of the more successful methods of doing this. The other surgical approach is to implant a penile prosthesis that overcomes the angulation mechanically. Results with these procedures are reported to be 60-80% satisfactory, including the return of orgasm.
Sometimes the condition disappears spontaneously. A careful look for other causes of impotence should be done before surgery.

Peyronie’s diseaseA type of superficial fibromatosis characterised by hypocellular dense fibrous tissue within the fascial sheath of one or both corpora cavernosa, leading to penile shaft curvature, painful erection, penile deformity, penile shortening with and without erection, focal penile induration, and, in many, erectile dysfunction. It is most common in men age 40 to 60 and may be associated with Dupuytren’s contracture, trauma, diabetes, gout, Paget’s disease, and urethral instrumentation.

Peyronie's diseaseA disorder of the penis in which the organ is bent at an angle when erect. This is the effect of local thickening and indistensibility of the fibrous tissue sheath. The thickening may extend into the erectile tissue and the condition is liable to interfere with sexual intercourse. The cause is unknown and the treatment difficult. Corticosteroid injections may help and surgical removal of the thickened areas may be tried. (Francois de la Peyronie, 1678–1747, French surgeon).
