Erectile Dysfunction Clinical Trial
Official title:
A Cohort Study of the Functional Significance of Internal Pudendal Artery Stenoses in Patients With Erectile Dysfunction
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.
