Background. Erectile dysfunction (ED) is the inability to achieve and/or maintain an erection for satisfactory sexual performance or intercourse. ED profoundly affects the quality of life. While the effects of dialysis on ED are documented, the benefits of renal transplantation are unknown.
Methods. This study evaluates the prevalence of ED and the effects of transplantation on ED in kidney transplanted patients. Erectile function was assessed using the self-administered International Index of Erectile Function (IIEF). The domains investigated by IIEF are: (1) erectile function, (2) orgasmic function, (3) sexual desire, (4) intercourse satisfaction, (5) overall satisfaction. At the entry patients underwent clinical examination by urologist and neurologist; blood was collected for biochemical analysis. One-hundred-fifteen (89%) patients filled in the questionnaire.
Results. Fifty-two (45%) patients did not complain about ED, which was reported by sixty-three patients (55%). No clinical and/or biochemical difference was found between patients with and without ED. Hypertension was equally present among patients; administration of beta-blockers was significantly more frequent among patients without ED. ED was already present during dialysis in 40 patients. After transplantation ED disappeared in 8 (20%), ameliorated in 13 (32,5%), worsened in 2 (5%), remained unchanged in 17 (42,5%) and appeared “ex novo” in 27 (43%) patients. ED is significantly correlated (p<0.01) to the age of subjects.
Conclusions. The data of the present study indicate that: 1) ED is still present in many transplanted men; 2) renal transplantation cures ED in only few cases; 3) ED may appear “ex novo” after transplantation.
