Prevalence, Risk Factors, and Erectile Dysfunction Associated With Peyronie's Disease Among Men Seeking Urological Care

Introduction: Peyronie's disease (PD) is a connective tissue disorder of the penis characterized by an abnormality in collagen structure of penile tunica albuginea.

Aim: We sought to investigate the prevalence, risk factors, and the relationship between erectile dysfunction (ED) and PD in male patients aged 30-80 years seeking urological care.

Methods: This is a cross-sectional study using data collected from October 2016 to October 2017 in an outpatient clinic associated with the Brazilian Public Health System. All men aged 30 to 80 years were invited to participate. Data collected were related to the clinical history and sexual habits of patients using the International Index of Erectile Function, in addition to the physical examination of the penis and laboratory parameters.

Main Outcome Measure: Descriptive statistics and multivariate logistic regression models tested the prevalence, risk factors, and the relationship between ED and PD in male patients.

Results: The study included 656 individuals, who were distributed as per age, marital status, race, educational level, and income. Of these participants, 86 (13.11%) presented with fibrous plaques compatible with PD at the physical examination. Among the risk factors evaluated, PD was associated with diabetes, smoking, and obesity in 43.02, 64.17, and 26.74% of patients, respectively. The presence of penile plaques compatible with PD was more prevalent in men with ED, history of penile trauma, and complaint of penile deformity. There was a higher prevalence of plaques in the distal penis.

Conclusion: The PD among the studied population was associated with risk factors such as diabetes, smoking, and obesity. Other clinical characteristics, such as history of penile trauma, penile deformity, and ED, were reported in patients with PD. There was a higher prevalence of plaques in the distal penis, specifically in the corona of the glans penis. The prevalence of PD was different from that in the published literature, our results show that numbers thus more studies are needed. Segundo A, Glina S.
