Background. Endothelial dysfunction plays a major role in erectile dysfunction (ED). Uric acid (UA) is a marker of endothelial dysfunction. We hypothesized that increased UA levels may be associated with ED and aimed to investigate whether there is a relationship between, UA and ED in hypertensive patients. Methods. A total of 200 hypertensive patients who have a normal treadmill exercise test were divided into two groups based on the Sexual Health Inventory for Men (SHIM) test (<21 defi ned as ED n = 110, and >= 21 defi ned as normal erectile function n = 90). The differences between the ED and normal erectile function groups were compared and determinants of ED were analyzed. Main results. The prevalence of ED was found to be 55.0%. Office blood pressure level was comparable between groups. UA levels were significantly increased in the ED group (6.20 +/- 1.56 vs 5.44 +/- 1.32, p = 0.01). In a regression model, age [odds ratio (95% confidence interval): 1.08 (1.04-1.14), p = 0.001], smoking [odds ratio: 2.33 (1.04-5.20), p = 0.04] and UA [odds ratio: 1.76 (1.28-2.41), p = 0.04] were independent determinants of ED. An UA level of >5.2 mg/dl had 76.2% sensitivity, 43.7% specificity, 62.9% positive and 59.4% negative predictive value for determining ED. Conclusion. UA is an independent determinant of ED irrespective of blood pressure control and questioning erectile function for hypertensive patients with increased UA levels may be recommended.
