Patient opinion of lower urinary tract symptoms and their treatment: a cross-sectional survey in Hong Kong public urology clinics.

INTRODUCTION Lower urinary tract symptoms collectively represent a common condition among ageing men. There are, however, limited data on the frequency of individual symptoms in patients who seek specialist care. We conducted a multinational survey in South-East Asia to evaluate patients' self-reported prevalence, bother, treatment, and treatment satisfaction of four lower urinary tract symptoms namely, urgency, nocturia, slow stream, and post-micturition dribble. This report presents the analysis of the Hong Kong subpopulation. METHODS This cross-sectional survey involved adult men aged over 18 years who attended a urology out-patient clinic because of lower urinary tract symptoms. A structured questionnaire, translated and validated in the local languages, was self-administered by patients. RESULTS Of 1436 respondents surveyed in the region, 225 were from Hong Kong of whom most were aged 56 to 75 years, retired, and had no history of any previous prostate surgery. Overall, the self-reported prevalence of nocturia of at least one void per night was 93% (95% confidence interval, 90%-97%), slow stream 76% (71%-82%), post-micturition dribble 70% (64%-76%), and urgency 50% (43%-56%). Symptoms for which most respondents reported "some" or "a lot" of bother included: nocturia, defined as at least two voids per night (77%), and urgency and post-micturition dribble (73%). Only 39% to 54% of patients had previously received treatment but were not entirely satisfied with it. An understanding of their condition remained suboptimal. CONCLUSIONS In Hong Kong, nocturia emerged as the most prevalent and one of the most bothersome symptoms among men who sought urologist care for lower urinary tract symptoms. Compared with the non-Hong Kong population, Hong Kong respondents tended to be highly symptomatic and bothered. They were, however, less likely to have received treatment and were generally less satisfied with previous treatment.
