This study, set up as a cross-sectional survey, seeks to delve into the disease burden and the demographic specifics of lower urinary tract symptoms (LUTS) among the male community in China. The investigators's main aim is to map out the overall and age-specific prevalence rates of LUTS within the Chinese male population. These insights are critical for understanding the public health dimensions of this condition. Moreover, the investigators plan to investigate several secondary aspects: the correlation of LUTS prevalence with factors like urbanization levels (rural vs. urban), geographical distribution, and lifestyle choices. Another significant focus will involve examining the treatment landscape for LUTS, looking at the portion of sufferers receiving treatment, the diversity in treatment durations, and the types of treatments employed (medication vs. surgery). This comprehensive analysis is intended to shed light on the prevailing management strategies for LUTS in China. The study is scheduled to unfold over 36 months and will comprise three pivotal phases: initial preparations, recruitment of subjects and collection of data, followed by the analysis of data and compilation of reports. The investigators will employ a range of methods such as questionnaires, physical exams, laboratory tests, imaging, and other medical evaluations to amass extensive data. This will allow the investigators to evaluate the prevalence of LUTS across various age groups among men and address the current gaps in epidemiological understanding.
