Epidemiological investigation on the prevalence of bladder hyperactivity in Huzhou, Zhejiang province

Abstract

Objective To investigate the prevalence of bladder hyperactivity in Huzhou city, Zhejiang province. Methods 1 872 patients aged over 50 years old male residents were selected as research subjects in Huzhou.To investigate the prevalence of bladder hyperactivity in the elderly male population in the local area.The correlation between age, IPSS score, body mass index, diabetes and the bladder was investigated. Results In 1 872 cases, the data were complete and in accordance with the requirements of this study were 1 863 cases.1 863 cases, 505 patients with bladder hyperactivity, bladder disease prevalence was 27.1%.Bladder hyperactivity patients with IPSS score (17.9±8.1)points, prostate volume (36.6±18.5)mL, QOL score (3.6±1.1) points, residual urine volume (26.9±3.5)mL in the bladder, were higher than those with non bladder hyperactivity, IPSS score (3.2±16.8)points, prostate volume (28.1±1.3)mL, QOL score (2.3±1.8)points, the differences were statistically significant (t=7.277, 5.910, 19.814, 2.406, P<0.01-0.05). Qmax(12.6±6.3)mL/s in the patients with bladder hyperactivity was significantly lower than Qmax(17.1±7.4)mL/s of non bladder hyperactivity, and the difference was statistically significant (t=3.577, P<0.01). With the increasing age of male population, the prevalence of bladder diseases was increased.With the increase of IPSS score, the incidence rate of bladder excessive activity increased.Diabetes, higher body mass index, the incidence of bladder excessive activity was higher. Conclusion Men with bladder hyperactivity disorder has higher prevalence in Huzhou city, Zhejiang province.Age, lower urinary tract symptoms, diabetes, obesity are the risk factors in the incidence of bladder disease.
