Factors associated with erectile dysfunction in male kidney transplant recipients

A transversal study was carried out in order to evaluate the prevalence of erectile dysfunction (ED) in adult kidney transplant patients of our region (N=243), and to investigate the sociodemographic, analytic, and clinical factors associated with it. To evaluate ED, the Spanish five items version of the International Index of Erectile Function (IIEF-5) was employed. Sociodemographic, analytic, and clinical data, including 12 cardiovascular risk factors, were also collected. A total of 199 patients (82%) were included. The median age was 52 y (43-62 y); 106 patients (54.9%) presented with ED. Variables associated with ED were: higher age; longer time on dialysis prior to transplantation; higher comorbidity; presence of diabetes mellitus; had undergone prostatic surgery or peripheric artheriopathy; lower diastolic pressure; and some anti hypertensive drugs. Logistic Regression Model performed step by step showed (R(2)=0.52) that factors independently associated with ED were: age, time on dialysis previous to transplant, and peripheric artheriopathy.
