Erectile dysfunction and Peyronie's disease diagnosis rates after penile fracture-a retrospective claims database cohort analysis.

Our objective was to analyze the rates of erectile dysfunction and Peyronie's disease following a penile fracture using a large, multi-institutional claims database. Inclusion criteria included men ages 15 or older with a diagnosis of penile fracture and any office visit within 5 years of the penile fracture. Exclusion criteria included prior erectile dysfunction, prescription of erectile aids, or penile prosthesis placement. Our primary outcome was the diagnosis of erectile dysfunction or prescription of phosphodiesterase-5 inhibitors within 5 years. A secondary analysis assessed rates of Peyronie's disease following penile fracture. 1242 men were identified with penile fracture and subsequently matched to men without penile fracture, resulting in equal cohorts of 1227 men. Men with a history of penile fracture were more likely to receive a diagnosis of erectile dysfunction or require phosphodiesterase-5 inhibitors (RR 3.18, 95% CI: 2.30-4.40). Men who did not undergo immediate repair had higher rates of erectile dysfunction or treatment (RR: 1.84, 95% CI: 1.22-2.78). Men over the age of 45 years who had a penile fracture were more likely to develop erectile dysfunction or treatment compared to men under 45 years (RR: 1.65, 95% CI: 1.14-2.39). Rates of Peyronie's disease were higher in men with a history of penile fracture (5.8% vs 0%, p < 0.0001). Rates of Peyronie's disease were lower if immediate repair of the fracture was performed (RR: 0.20, 95% CI: 0.10-0.41). Men over the age of 45 years with penile fracture were more likely to develop Peyronie's Disease within 5 years compared to men under the age of 45 years penile fracture (RR: 3.72, 95% CI: 1.94-7.16). Penile fracture increases the risk of both erectile dysfunction and Peyronie's disease, especially those treated with conservative measures or over the age of 45 years compared to patients under 45 years with a penile fracture.
