Correlation between metabolic syndrome and lower urinary tract symptoms of males and females in the aspect of gender-specific medicine: A single institutional study

Abstract

Purpose: We attempted to examine the correlation between metabolic syndrome and lower urinary tract symptoms (LUTS) in the aspect of gender-specific medicine. Materials and Methods: A total of 922 patients participating in a health examination completed the International Prostate Symptom Score (IPSS) questionnaire and the Overactive Bladder Questionnaire Short Form (OABq-SF) symptom bother scale from March 2008 to July 2009. Metabolic syndrome was defined by using the National Cholesterol Education Program Adult Treatment Panel III criteria announced in 2001. We analyzed differences in lower urinary tract symptoms according to the presence of metabolic syndrome and the component elements of metabolic syndrome. Results: The subjects were 538 males and 384 females with a mean age of 48.8±6.8 years. Among all patients, the number of patients with metabolic syndrome was 143 (15.5%); there were 110 males (20.4%) and 33 females (8.6%), showing a significant difference. There were no differences in scores on the IPSS or OABq-SF with respect to the presence or absence of metabolic syndrome in males. In females, however, there were significant differences in the IPSS and OABq-SF depending on the presence or absence of metabolic syndrome. In males and females, the IPSS total score was significantly correlated with age. Also, high-density lipoprotein (HDL) cholesterol in males and triglyceride in females was significantly correlated with the IPSS total score. Conclusions: There are sex differences in the morbidity rate of metabolic syndrome and its effect on lower urinary tract symptoms. Therefore, it is necessary to consider gender-specific medicine in the diagnosis and treatment of LUTS. © The Korean Urological Association, 2010.
