Penile Curvature Correction through Plication Surgery

Peyronie's Disease

The penis is composed of two cavernous bodies, of a mass of spongy tissue surrounding the urethra (the tube through which urine flows), and of a glans, or head, at the tip. The two cavernous bodies are covered by a thick, elastic membrane called the tunica albuginea, which creates an erection by increasing the penis' girth and length. Peyronie's disease is caused by the development of localized fibrous segments in the tunica albuginea of the sponge-like region of the penis which in turn causes it to curve during an erection.


What causes the disease?

It has no known causes, but 37% of the many existing hypotheses involve trauma.


Are there any predispositions to the disease?

Approximately 10% of men with Peyronie's also develop Dupuytren's contracture. Diabetes, smoking, the use of beta blockers, Paget's disease and rheumatoid arthritis can contribute to the development of the disease.


What is its rate of occurrence?

The incidence of Peyonie's disease is 7%. It usually develops at the age of 53 on average, and is considered rare before the age of 40.


How does the disease evolve?

Changes in the penile curvature can vary over time. Curvature may spontaneously disappear just as much as it can evolve into severe deformity. Determining how curvature will evolve in the disease's early stages is therefore difficult.

Peyronie's disease usually evolves in two phases:


Acute phase

The initial inflammatory phase may be accompanied by painful erections, the formation of a lump along the shaft and a change in the curvature of the penis during erection. Pain may occur randomly or only during an erection. In the majority of cases, pain seems to disappear within 12 to 18 months.


Chronic phase

The chronic phase is characterized by stable curvature. Patients often do not feel pain at this stage.


How is the disease diagnosed?

The urologist can diagnose Peyronie's disease based on a patient's medical history or through a physical examination. Diagnostic tests are not necessary.


How is Peyronie's medically treated?

During the acute phase: nonsurgical shock wave therapyis used to reduce pain.

During the chronic phase: plication surgery is carried out in order to correct penile curvature.


Are there any plaque injection treatments available?

In many studies, Collagenase (medication injected directly into plaques) has been proven to reduce curvature and plaque size, and improve erectile dysfunction. However, it is not yet available in Canada.


Can Peyroni's be physically treated?

Extracorporeal shock wave lithotripsy seems to reduce the pain more quickly during the acute phase. This treatment is available through private practice at Dr Carlos Marois' urology clinics. A four-week series of weekly, half-hour appointments are required to treat plaque.

Plication Surgery

Penile Straightening through Plication Surgery

Corrective surgery is required in less than 10% of cases and is carried out to lessen curvature during erection and facilitate intercourse. Plication surgery is considered only if the curvature is severe and has been making intercourse difficult or impossible for at least 2 years. It is recommended for patients with good erectile capacity, whose penile deformation is simple and inferior to 60°. The patient's penis must also be of sufficient length.


You may be asked to provide photos of your erect penis in order to help the urologist confirm which surgical technique to use. These photos may also allow him/her to assess the postoperative results.


With plication surgery, the urologist shortens the albuginea by removing a portion of the tunica albuginea from the side opposite to the curvature with non-absorbable surgical suture (stitches). The results of this treatment are very satisfactory; with a reported success rate ranging from 79% to 100% for penile straightening, and a 67% to 100% patient satisfaction rate.


How is the surgery carried out?

The surgery can be performed under spinal anesthesia or general anesthesia at a hospital. In private practice, it is carried out with a penile block, as in the case of circumcision.


After anesthesia, an artificial erection is induced by administering medication through an intracavernous injection. This allows the urologist to determine the location and the number of plications to carry out.


Usually, the surgical incision is made a few millimetres behind the penis gland in a circular fashion in order to lift the skin of the penis from the corpus cavernosa. In an uncircumcised patient, circumcision is generally proposed to avoid complications related to postoperative edema. In a circumcised patient, the incision is located at the same level of the old scar.


The skin is then closed using absorbable sutures (stitches). A bandage is also wrapped around the penis and left in place, just as after circumcision.


A urinary catheter may be required within the first 24 hours after surgery.

What kind of postoperative care is involved?

Postoperative care for penile plication surgery is the same as that of circumcision. Painkillers are prescribed to the patient. The patient should also:

  • avoid sexual activity (with erection) for at least 6 weeks after surgery to allow for healing
  • avoid physical exertion for one week
  • take sick leave from work if necessary


A postoperative appointment must be scheduled 2 months after the procedure to check the quality of the recovery. Photographs of your erect penis may be requested to facilitate the assessment.


Are there any risks or complications?

Complications directly related to the surgery are rare but possible:

  • surgical failure
  • narrowing of the penis (at rest or erect)
  • a few nodules or bumps may be felt under the skin of the penis due to the palpation of the non-absorbable sutures
  • pain during sexual intercourse
  • recurrence of the Peyronie's disease


Internal complications (hematoma, urinary infection and retention) are occasional. Sensitivity disorders or vascularization of the penis (transient or permanent) are exceptionally rare.


When should I consult a urologist?

  • If the pain increases
  • Scar leakage
  • Swelling of the penis (edema, hematoma)
  • Fever
