Sildenafil citrate improves erectile function and urinary symptoms in men with erectile dysfunction and lower urinary tract symptoms associated with benign prostatic hyperplasia: a randomized, double-blind trial.
J Urol 2007; 177(3):1071-7JU

Abstract

PURPOSE

We evaluated sildenafil for erectile dysfunction and lower urinary tract symptoms in men with the 2 conditions.

MATERIALS AND METHODS

This was a 12-week, double-blind, placebo controlled study of sildenafil in men 45 years or older who scored 25 or less on the erectile function domain of the International Index of Erectile Function and 12 or greater on the International Prostate Symptom Score. Men with confirmed or suspected prostate malignancy, or prostate specific antigen 10 ng/ml or more were excluded. End points were changes in International Index of Erectile Function domain scores, International Prostate Symptom Score (irritative, obstructive and quality of life), the Benign Prostatic Hyperplasia Impact Index, the Self-Esteem And Relationship questionnaire and Erectile Dysfunction Inventory of Treatment Satisfaction Index Score.

RESULTS

The 189 men receiving sildenafil had significant improvements in erectile function domain score vs the 180 on placebo (9.17 vs 1.86, p<0.0001) and on all other International Index of Erectile Function domains. In men on sildenafil vs placebo significant improvements were observed in International Prostate Symptom Score (-6.32 vs -1.93, p<0.0001), Benign Prostatic Hyperplasia Impact Index (-2.0 vs -0.9, p<0.0001), mean International Prostate Symptom Score quality of life score (-0.97 vs -0.29, p<0.0001) and total Self-Esteem And Relationship questionnaire scores (24.6 vs 4.3, p<0.0001). There was no difference in urinary flow between the groups (p=0.08). Significantly more sildenafil vs placebo treated patients were satisfied with treatment (71.2 vs 41.7, p<0.0001). Sildenafil was well tolerated.

CONCLUSIONS

Improved erectile dysfunction and lower urinary tract symptoms with sildenafil in men with the 2 conditions were associated with improved quality of life and treatment satisfaction. Daily dosing with sildenafil may improve lower urinary tract symptoms. However, the lack of effect on urinary flow rates may mean that a new basic pathophysiology paradigm is needed to explain the etiology of lower urinary tract symptoms.
