OBJECTIVETo investigate the situation of overactive bladder (OAB) in a community-based male population.

METHODSMale participants over 50 years old were randomly selected from multiple communities in Beijing. The evaluation of lower urinary tract symptoms (LUTS) including the International Prostate Symptom Score (IPSS), quality of life (QOL) score, prostate volume and post voiding residue (PVR) by abdominal ultrasonography, and maximum flow rate (Qmax). Definition of OAB was determined as the score of item number 4 in IPSS ≥ 2.

RESULTSOf 1656 male participants enrolled, a total of 1639 men met our study criteria. The mean age was (64 ± 10) years. The prevalence of OAB was 26.3% (431/1639), and was significantly related to age, IPSS, QOL score, prostate volume, PVR and Qmax (P < 0.01). The prevalence of OAB was closely associated with aging (P < 0.01) and the degree of LUTS (P < 0.01).

CONCLUSIONSThe prevalence of OAB increased with aging of the community-based male population. OAB would obviously affect the quality of life of the aging men.

OBJECTIVE: To evaluate the quality of life of patients with interstitial cystitis/bladder pain syndrome (IC/BPS), to compare the difference between IC/BPS and overactive bladder (OAB) pain syndrome, and to explore the related factors affecting the quality of life of IC/BPS patients. METHODS: The demographic data of female outpatients with IC/BPS in Beijing Hospital and other medical centers in China were collected. The quality of life of the patients was investigated by multi-angle questionnaires and compared with the data of OAB patients. According to the influence degree of quality of life, the patients with IC/BPS were divided into mild-moderate group and severe group. RESULTS: In this study, 109 patients with IC/BPS were included. The average age was (46.4±14.3) years and the average course of disease was (39.4±51.6) months. Compared with the OAB patients, the patients in IC/BPS group had a longer average course of disease (P=0.008), a lower proportion of the patients of first visit for the disease (P < 0.001), a higher score of the American Urological Association symptom index (AUA-SI) (P < 0.001), a lower body mass index (BMI) ratio (P=0.016), and a lower incidence of constipation (P=0.006). IC/BPS had the greatest impact on family life, followed by social activity. The score of IC/BPS related symptoms on family life was significantly higher than that of the OAB group (P=0.003). The top three symptoms of the IC/BPS patients were pain (45%), frequency (28%) and urgency (17%). The score of quality of life in the IC/BPS patients was significantly higher than that in the OAB patients (P < 0.001). Caffeine intake (P=0.034) and constipation (P=0.003) might be the factors influencing the quality of life of the patients with IC/BPS. CONCLUSION IC/BPS has a great influence on the quality of life of patients. Caffeine intake and constipation may be related factors affecting the quality of life of patients with IC/BPS. Urologists should recommend changes in diet and lifestyle to reduce symptoms and improve the patients' quality of life.

A comprehensive and correct understanding of epidemiologic finding about lower urinary tract symptoms (LUTS) is important for several reasons. First, LUTS are highly prevalent in both genders all around the world and are expected to be a major concern to physicians in the near future because of the rapid rise in the elderly population. Second, it is crucial to observe trends in prevalence when national health care policy is established. By using a Medline search with various terms related to LUTS and prevalence, a review of epidemiologic studies was undertaken with an emphasis on the status in Korea. Despite the suggestions made by the International Continence Society, the lack of uniform definitions and the lack of a unified threshold of symptoms are the biggest obstacles in epidemiologic study with regard to LUTS. Most Korean epidemiologic studies on LUTS have been reported since 2000 and reveal that the prevalences of specific clinical conditions, such as LUTS, benign prostatic hyperplasia, overactive bladder, and detrusor underactivity, are in line with prevalences in Western counties. However, the prevalence of nocturia is somewhat different from that in Western countries. Many epidemiologic studies of LUTS have provided us with valuable information and a better understanding of the clinical conditions. Given that the impact of these clinical conditions on quality of life and health care cost will be emphasized more in the near future, more studies on optimal management approaches to LUTS are needed on the basis of this knowledge.

OBJECTIVE: To investigate the prevalence, risk factors of overactive bladder (OAB) and the factors affecting the severity of OAB symptoms. METHODS: A total 822 interviews with women aged 18–80 years who visited public health centers were conducted between April 2014 and April 2015. The questionnaire was composed of 16 questions about urinary symptoms, 14 questions about self-treatment and the use of complementary and alternative medicine, and 21 questions about socio-demographic characteristics. The diagnostic criterion for OAB is a total OAB symptom score of 3 and more, with an urgency score of 2 or more. To know the risk factors and factors affecting the severity of OAB, the multivariate logistic regression analysis was performed. RESULTS: One hundred fifty-seven participants (19.3%) were diagnosed with OAB, of whom 10.7%, 8.1%, and 0.7% had mild, moderate, and severe OAB symptoms, respectively. In addition, the prevalence of OAB increased with age. Among all the participants, 39.1% had stress incontinence, among them 32.7% had OAB as well. The significant risk factors of OAB were identified as age, current smoking, hyperlipidemia, cardiovascular and renal disease, whereas, the factors affecting the severity of OAB were age, current smoking, and hyperlipidemia. CONCLUSION: Those who have risk factors and factors affecting severity of OAB should be educated to increase OAB awareness and act of urinary health promotion.

This review assessed the epidemiology of voiding dysfunctions in South Korea. Comprehensive understanding of this epidemiology is crucial because the senior population and the social burden are increasing because of voiding dysfunctions is growing. We searched the medical records using several terms related to voiding dysfunction: benign prostatic hyperplasia, urinary incontinence, lower urinary tract symptoms, overactive bladder, and nocturia. We then estimated the prevalence of voiding dysfunctions in South Korea; our data were comparable with those from other countries, with slight differences. The ranges of incidences varied widely between studies, mostly because investigators defined disorders differently. Voiding dysfunction greatly affects healthcare costs and individual quality of life; therefore, more proper and valuable epidemiologic data are needed. In addition, efforts to unify the definitions of various voiding dysfunctions and progress in investigational methodologies using multimedia are warranted.
