Abstract

Introduction

The magnitude of penile deformity is a critically important factor in Peyronie's disease, as it is associated with increased difficulty in penetrative sexual intercourse and in turn with negative psychosocial consequences. Deformity magnitude also influences treatment choice when surgical correction is indicated.

Aim

To determine the concordance between patient and physician assessment of magnitude of penile curvature in men with Peyronie's disease.

Methods

Patient assessment of curvature was obtained at initial interview. Physician assessment was performed using intracavernosal injection-assisted erection using a goniometer applied during excellent penile rigidity.

Main Outcome Measures

Patient and physician assessments of penile curvature.

Results

The sample consisted of 192 men with a mean age of 54 ± 12 years old. Mean curvature on patient and physician assessment was 33 ± 17 and 36 ± 18 degrees, respectively. Only 49% of patients (94) correctly assessed their curvature, whereas 35% underestimated and 16% overestimated it.

Conclusions

Only half of PD patients accurately assess their penile curvature, with more than twice as many patients underestimating it than overestimating it. These data suggest that patient self-reporting of penile curvature should not be used as a clinical marker or end point in Peyronie's disease trials.
