Abstract
Introduction. The purpose of this study was to investigate the association between severity of lower urinary tract symptoms LUTS, erectile dysfunction ED and metabolic syndrome. Methods. Our study population included a consecutive series of 190 patients with LUTS International Prostate Symptom Score-IPSS >7 with or without manifestations of the metabolic syndrome. The diagnoses of diabetes mellitus and hypertension were obtained from the patient's medical history. Data on blood pressure, waist measure, body height and weight were collected and body mass index were calculated. Patients were assessed based on the International Index of Erectile Function IIEF for ED and IPSS and IPSS-Quality of Life for LUTS. Blood samples were drawn from fasting patients to determine, fasting blood glucose FBG, triglycerides, HDL-cholesterol and serum total testosterone levels. Results. In severe LUTS patient group, IIEF erectile function domain scores were significantly lower than moderate LUTS patient group p < 0.05. Multiple logistic regression analysis confirmed that presence of ED was the most predictor of severe LUTS. The prevalence of metabolic syndrome was higher in patients with severe LUTS 26vs. 46, p 0.009. The severe form of the LUTS was significantly correlated with waist circumference >102 cm p < 0.05, blood pressure ≥13085 mmHg p < 0.05 and FBG >110 mgdl p < 0.01. Conclusion. Obesity, high plasma level of FBG and hypertension constitute risk factors for the development of severe LUTS. Metabolic syndrome may play a key role in the pathogenesis in both ED and LUTS. Presence of ED is the most predictor of severe LUTS. © 2009 Informa UK Ltd.
