Serum lipid levels in benign prostatic hyperplasia.

The relationship between serum lipid levels and measures of benign prostatic hyperplasia was investigated. The study was community based. All the participants had undergone a urological investigation which included International Prostate Symptom Score (I-PSS) and Quality of Life Score (QoL), serum lipid concentrations and determination of prostate volume with transrectal ultrasonography. Body mass index was calculated with the formula of weight (kg)/surface area (m(2)) respectively. Men were considered obese if their body mass index was over 25 kg/m(2). BPH was defined by prostate volume greater than 20 ml and I-PSS greater than seven. Comparisons of serum lipid levels between men with BPH and without BPH were done. There was no correlation for serum lipid levels with either mean I-PSS and QoL scores. However, triglyceride and cholesterol levels were the lowest in severe symptomatic men than men with low symptoms. Using clinical definition of BPH that prostate volume was greater than 20 ml and I-PSS was greater than seven, men with BPH had not significantly different serum lipid levels from men without BPH. Our population-based data reflect that there was no relationship between serum lipid levels and certain physiological measures of lower urinary tract symptoms and clinical benign prostatic hyperplasia.
