The prevalence of lower urinary tract symptoms in a Chinese population, and the correlation with uroflowmetry and disease perception

Objectives To evaluate the prevalence of lower urinary tract symptoms (LUTS) in a population of Chinese men, and its correlation with uroflowmetry and disease perception. Materials and methods Male volunteers above 40-year old were recruited in the community. Assessment with International Prostatic Symptom Score (IPSS), uroflowmetry, and a quiz on prostatic disease knowledge with 12 true–false-type questions were performed. Correlation of IPSS with uroflowmetry results and prostatic disease knowledge was analyzed. Results A total of 319 men were recruited for the study, with a mean age of 62 ± 8 years. About 69.3 % of them had moderate-to-severe symptoms on IPSS. A statistically significant correlation was found between IPSS and Q max ( r = −0.260, p
