RESUMEN
PURPOSE: We studied 278 men who are over 40 years of age to educate BPH and to evaluate the prevalence of BPH in Busan city of Korea. MATERIALS AND METHODS: Between December 1997 and February 1998, 278 men in Busan city were investigated. The screening tests included urinary symptom questionnaire (IPSS), digital rectal examination (DRE), prostate specific antigen (PSA) and uroflometry. RESULTS: Based on the IPSS, 36.3%, 49.7% and 14.0% of the men were mild (1-7), moderately (8-19) and severely (20-35) symptomatic. The mean maximal flow rate and PSA for men 40 to 49, 50 to 59, 50 to 69 and over 70 years old were 18.4 ml/sec, 14.2 ml/sec, 12.9 ml/sec, 10.6 ml/sec and 1.081 ng/ml, 1.195 ng/ml, 1.527 ng/ml, 2.352 ng/ml respectively. CONCLUSIONS: The prevalence rate of clinical BPH(IPSS>7 and peak urinary flow rate<10 ml/sec) in community-based study of 278 men was 25.5%.
