Peyronie’s Disease: Evaluation and Clinical Approach to Penile Curvature
Specialized clinical evaluation of Peyronie’s Disease, focused on identifying fibrosis, associated pain, and the functional impact of penile curvature.
What Is Peyronie’s Disease?
Peyronie’s Disease (PD) is an acquired condition characterized by the formation of fibrotic plaques — areas of rigid scar tissue — within the corpora cavernosa of the penis.
These changes may limit the normal expansion of penile tissue during erection and may be associated with different clinical manifestations, such as:
- Penile curvature (deviation of the penile axis);
- Pain, especially during the initial stage of the disease;
- Progressive changes in penile length or girth;
- Impairment of erectile function, in some cases.
The intensity of symptoms and the functional impact vary according to the stage of the disease and the individual characteristics of each patient.
The Two Phases of Peyronie’s Disease
Most Frequent Clinical Characteristics
Focus of the Medical Approach
Acute (Inflammatory) Phase
Pain associated with erection, inflammatory signs, and possible progression of curvature and fibrosis.
Pain control and clinical measures aimed at stabilizing plaque progression, according to medical evaluation.
Chronic (Stable) Phase
Reduction or disappearance of pain, with stabilization of curvature and dimensional changes.
Evaluation of the need for corrective intervention, including surgical options, when clinically indicated.
Diagnosis: Evaluation of Fibrosis and Penile Curvature
The diagnostic evaluation of Peyronie’s Disease is based on a structured clinical protocol designed to identify the location and extent of fibrotic plaques, as well as the functional impact of penile curvature.
Essential Examinations in Clinical Evaluation
1. Clinical History and Physical Examination:
Detailed evaluation of the patient’s clinical history, including symptom onset, presence of pain, and progression of curvature. The physical examination allows palpation of fibrotic plaques and, whenever possible, documentation of curvature and associated deformities.
2. Inspection and Palpation in the Flaccid State:
With the penis in a flaccid state, careful palpation of the corpora cavernosa is performed to identify areas of fibrosis, allowing assessment of their location and consistency.
3. Pharmacologically Induced Erection Assessment:
Pharmacological induction of erection allows observation of the penis in a rigid state, enabling evaluation of the degree and type of curvature, associated deformities, and erectile rigidity under controlled conditions.
4. Dynamic Penile Doppler Ultrasound
A fundamental complementary examination for assessing penile blood flow, including arterial inflow and venous drainage mechanisms. It also allows identification of vascular alterations or internal fibrosis that may be associated with concomitant erectile dysfunction.
Treatment of Peyronie’s Disease: Focus on Functional Preservation
The therapeutic approach to Peyronie’s Disease aims primarily to relieve pain, improve penile curvature, and preserve, whenever possible, penile function and anatomy.
The treatment strategy depends on the stage of the disease, the degree of curvature, and the functional impact identified during clinical evaluation.
Surgical Approaches: Principles of Penile Reconstruction
Surgical techniques for correcting penile curvature may follow different principles. Some traditional approaches are based on plication of the side opposite the curvature, which in certain cases may be associated with penile shortening.
Modern reconstructive approaches seek to act directly on the side affected by fibrosis, allowing correction of the penile axis while focusing on preservation of anatomy and function, within the limits defined by the individual evaluation of each case.
Surgical indication and the choice of technique are always made carefully, based on medical criteria and the specific characteristics of the patient.
Treatment Option
Clinical Indication
Adopted Approach
Minimally Invasive Treatments
Mainly indicated for patients in the acute phase of the disease, with pain and active inflammatory signs.
The approach may include targeted injectable therapies, physiotherapy programs with penile traction, and oral medication, always aiming to stabilize disease progression according to clinical criteria and a defined medical protocol.
Surgical Correction of Curvature
Stable curvature with functional impact, particularly difficulty or impossibility of sexual intercourse.
Application of a reconstructive surgical approach selected based on penile anatomy and the individual characteristics of the case.
Peyronie’s Disease Associated with Erectile Dysfunction
Situations in which fibrosis is associated with clinically significant erectile dysfunction refractory to clinical therapy.
Penile prosthesis implantation, which may be combined with curvature correction during the same surgical procedure when clinically indicated.
