Relationship between lower urinary tract symptoms and metabolic syndrome in a Chinese male population

To investigate whether the metabolic syndrome (MetS) is a risk factor for lower urinary tract symptoms (LUTS), as defined by the International Prostate Symptom Score in a Chinese male population with benign prostate hyperplasia (BPH).

We retrospectively analyzed the clinical data obtained from 1,052 Chinese men with BPH. Serum levels of prostate specific antigen, fasting blood glucose (FBG), high-density lipoprotein cholesterol, total cholesterol and triglyceride were determined and recorded. Multiple logistic regression statistical analysis was used to investigate the degree of the association between LUTS and MetS.

Of the 1,052 enrolled patients, 648 (61.60 %) had moderate LUTS and 404 (38.40 %) had severe LUTS. A multiple logistic regression analysis showed that age (OR 2.02, 95 % CI 1.04-4.63), FBG (OR 3.65, 95 % CI 1.68-7.98) and presence of MetS (OR 3.64, 95 % CI 1.24-6.14) were significant predictors of severe LUTS.

The results of our study suggest that MetS is associated with an increase risk of total volume and annual growth rate of prostate.
