How is congenital penile curvature diagnosed?

The diagnosis of congenital penile curvature is reasonably simple and it is mainly based on the characteristics of the onset of the deformity and on the examination of the genitalia of the patient. The majority of patients with congenital penile curvature notice the deformity during adolescence. A thorough examination of the shaft of the penis will confirm the absence of the indurated scars that are the typical hallmark of acquired penile curvature (Peyronie’s Disease).

The degree of curvature and the direction of the bend can be assessed only during full erections, when the tunica albuginea of the corpora cavernosa is fully stretched. 

Self-photography of the penis in the erect state is not an ideal tool as it can grossly underestimate the degree of the curvature. This is because of two main reasons; the first one is that a picture allows assessing the deformity in two planes rather than tridimensionally, while the second one is that, if the erection is incomplete, the deformity will appear less marked.

The best way to assess the curvature is during an artificial erection test performed in clinic after the administration of a vasoactive drug. During the artificial erection, the surgeon is able to assess adequately the curvature in all tridimensional planes.

When suspecting acquired penile curvature (Peyronie’s Disease), if a plaque cannot be palpated, ultrasonography can be extremely useful to identify small plaques and to help the surgeon to differentiate between the two conditions.

As congenital penile curvature can be associated with anomalies of the penile urethra, it is very important to examine the external urethral meatus and the distal urethra at the time of the assessment.
