Summary
Using a vacuum erection device without a pressure-release valve on an already erect penis caused severe injury. This resulted in vacuum-induced vasculogenic impotence and Peyronie's disease, requiring surgical intervention.
Area of Science:
- Urology
- Andrology
- Sexual Medicine
Background:
- Vacuum erection devices (VEDs) are commonly used for erectile dysfunction.
- Nonmedical VEDs may lack safety features like pressure-release valves.
- Improper use of VEDs can lead to penile injury.
Observation:
- A 66-year-old man used a nonmedical VED on a spontaneously rigid erection.
- Excessive overinflation occurred due to the absence of a pressure-release valve.
- This led to penile curvature, reduced rigidity, and Peyronie's disease.
Findings:
- Physical examination revealed a dorsal penile plaque and abnormal erectile function tests.
- Dynamic testing confirmed vasculogenic impotence with veno-occlusive dysfunction and penile curvature.
- High pulling forces (estimated 29 pounds) from the VED are hypothesized to be the cause.
Implications:
- VEDs can cause significant penile damage, including Peyronie's disease and veno-occlusive dysfunction.
- The absence of safety features and application on a rigid penis increases injury risk.
- Patient education on safe VED use is crucial to prevent such adverse events.
