IntroductionFew population-based data are available evaluating the prevalence of lower urinary tract symptoms LUTS in Asia. The objective of our study was to determine LUTS prevalence in China, Taiwan, and South Korea using International Continence Society ICS 2002 criteria.

MethodsAn Internet-based self-administered survey among individuals aged at least 40 years with the ability to use a computer and to read the local language. Survey questions included ICS symptom definitions and the international prostate symptom score IPSS. Data analysis was based on descriptive statistics and post hoc significance testing.

ResultsThere were 8284 participants, of whom 51% were women and 34% were aged at least 60 years. LUTS prevalence was slightly higher in men than women 62.8% vs. 59.6%; p = 0.004, increasing significantly with age p = 0.001. All three ICS symptom groups voiding, storage, and post-micturition were present in 35% of individuals with LUTS. Symptoms with the highest overall prevalence were nocturia, frequency, incomplete emptying, and terminal dribble. The most bothersome symptoms were terminal dribble, nocturia, and urgency. According to IPSS scores, 87% of participants had at least mild symptoms; 43% of those aged over 60 years had moderate-severe symptoms. The percentage of participants with any LUTS who had visited healthcare professionals because of urinary symptoms was 26%, rising to 45% amongst individuals with all three symptom groups p = 0.001 vs. other ICS symptom groups.

ConclusionsLUTS are highly prevalent in men and women aged at least 40 years who participated in this study in China, Taiwan, and South Korea and increases with increasing age. A minority of individuals with LUTS seek healthcare and our results suggest an increased patient awareness of LUTS is required.
