Evaluation of microalbuminuria in patients with erectile dysfunction

Abstract

Introduction: The recent sophisticated diagnostic procedures aimed at identifying the exact cause of erectile dysfunction (ED) are often complicated in clinical application, invasive, or highly expensive. Microalbuminuria, a test easy to perform and of low cost, is a marker of extensive endothelial dysfunction, and it has been suggested to be linked to ED. Aim: The aim of this study was to investigate the eventual role of microalbuminuria in differentiating patients with arteriogenic and non arteriogenic ED. Methods: The diagnosis of ED was based on the International Index of Erectile Function 5-questionnaire, and patients were classified as arteriogenic (N = 29) and non-arteriogenic (N = 49) in relation to the results of echo-color-doppler examination of cavernosal arteries in basal conditions and after intracavernous injection of 10 μg prostaglandin E1. Main Outcome Measures: The microalbuminuria of 78 males without the most common atheriosclerotic risks and with ED was measured. Results: Microalbuminuria, defined as urinary albumin/creatinine ratio, was not significantly (P > 0.05) different between patients of the two groups. Conclusions: Our data show that in ED patients the cavernosal arteries damage, as assessed by dynamic echo-color-doppler, may be independent on or precede extensive endothelial dysfunction, and that microalbuminuria cannot be predictive of penile arteriogenic etiology. © 2009 International Society for Sexual Medicine.
