Abstract:
Objective To investigate the prevalence of benign prostatic hyperplasia (BPH) in Beijing. Methods A cross-sectional study was performed at Beijing communities in men aged over 50 years. The International Prostate Symptom Score (IPSS) questionnaire was used to evaluate the symptoms. Transabdominal ultrasonography was used to measure prostate size and the residual urine volume(RUV). Uroflowmetry was performed to record the maximum flow(Q_(max)). One-way ANOVA was used to analysis the differences. Results 1644 subjects were enrolled and the mean age was 64. 5 years (range 50 - 93 years). The mean IPSS, prostate weight andQ_(max) were 9. 9±8. 2, (30. 8± 19.4) and (14. 7 ± 7. 5)ml/s, respectively. They had correlation with age (r=0. 388,0. 262, - 0.371). The prevalence of moderate-severe lower urinary tract symptoms (LUTS) was 50. 8% (835/1644). Prostate volume was greater than 20 ml in 69. 7%(1146/1644) of the subjects.Q_(max) was less than 15 ml/s in 53. 8% (883/1642) of the subjects. Conclusions In men age over 50 years in Beijing, there is positive correlation between LUTS, prostate size and age, and negative correlation between Q_(max) and age. The prevalence of BPH, defined as IPSS greater than 7, maxium flow rate less than 15 ml/s and prostate size greater than 20 ml, is 26. 8%(441/1644).
