Abstract:
PURPOSE: Study was done on the lower urinary tract symptoms(LUTS) associated with the benign prostatic hyperplasia(BPH) in the community based populations in Chungbuk province, and correlation among these symptoms, age, prostate volume, and flow rate was evaluated. MATERIALS AND METHODS: All men(764 men) living in Chungbuk province in Korea were invited to undergo measurements of peak flow rate, TRUS and to complete symptom scores and previously validated lifestyle questionnaire. RESULTS: Moderate to severe symptoms(symptom scores 8 or more) were found in 348 of our 695 samples(50.1%). A good correlation was observed between the total symptom score and quality of life questionnaire(r=0.68, P<0.001). The IPSS was weakly correlated with age(r=0.372, P<0.001) or peak flow rate(r=-0.27, P<0.001). Additional aim of this study was to determine the relative impact on the prevalence rates of the inclusion of these different parameters in the case definition of BPH. The highest overall prevalence of 27.7%(Chi-square 18.62, P<0.001) occurred using the definition that combined a prostate volume >20 cm3, and IPSS > or =8, while the lowest prevalence rate of 7.64%(Chi-square 32.03, P<0.001) occurred with the definition that combined a prostate volume >20 cm3, an IPSS > or =8, peak flow rate < or =10 ml/s, and urine volume >100 ml. CONCLUSIONS: Thus, the prevalence rates depended very much on the parameters used in case definition. Follow-up would establish the necessity of a work-up request and treatment for BPH and help determine the best clinical definition of BPH.
