Pudendal Assessment in Erectile Dysfunction

Terminated

• Conditions: Erectile Dysfunction

• Registration Number: NCT01262833
• Lead Sponsor: University of Pennsylvania

Brief Summary

The study will address the role of internal pudendal artery disease in erectile dysfunction (ED), and whether it might eventually be amenable to intervention with stenting. There is currently a small trial investigating the potential benefit of stenting for erectile dysfunction, but the relationship between pelvic arterial stenoses and erectile dysfunction is not yet proven. The investigators intend to perform angiography on patients both with and without erectile dysfunction, to see whether internal pudendal artery disease is more common in the population with erectile dysfunction. In addition to angiography, stenoses will be examined using fractional flow reserve. The degree of internal pudendal artery disease will then be correlated with the degree of erectile dysfunction using a validated questionnaire, the International Index of Erectile Function (IIEF). Patients will then complete IIEF questionnaires for 5 years to assess the relationship between internal pudendal artery disease and progression of erectile dysfunction.

Exclusion Criteria

• Patients with ED from a non-arterial cause, including hormonal, neurological, or trauma-related (as determined by past medical history routinely performed prior to catheterization)
• Patients requiring urgent catheterization (e.g. acute coronary syndrome or cardiogenic shock)
• Patients with a creatinine >1.5 mg/dL and those deemed at increased renal risk (such as from receiving >200 mL of dye during the primary procedure, post renal transplant or single kidney), as the additional contrast dye required for angiography would pose an undue risk of progressive kidney disease
• Patients with other illnesses that reduce their life expectancy to less than one year

Primary Outcome Measures

Name	Time	Method
Pudendal Assessment in Erectile Dysfunction	Up to Five years	The primary exposure will be hemodynamically significant internal pudendal artery stenoses as a predictor of erectile dysfunction

Secondary Outcome Measures

Name	Time	Method
Pudendal Assessment in Erectile Dysfunction	up to five years	Secondary analyses will include correlation between bilateral disease and erectile dysfunction, as well as the contribution of small vessel disease (distal to the internal pudendal artery). The severity of disease by IIEF questionnaire will also be compared to the severity of disease by angiography. We will continue through 5-year follow-up of patients with yearly IIEF questionnaires to determine if changes in erectile dysfunction can be predicted by baseline internal pudendal artery disease.
