The prevalence of lower urinary tract symptoms in korean men aged 40 years or older: a population-based survey.

ABSTRACT:

Purpose

The aim of this study was to evaluate the prevalence of lower urinary tract symptoms (LUTS) among Korean men aged ?40 years.

Methods

We performed a population-based, cross-sectional door-to-door survey on a geographically stratified random sample of men aged ?40 years. All respondents were asked about the presence of individual LUTS using a questionnaire based on 2002 International Continence Society definitions. For comparison, we also defined nocturia as two or more nocturnal micturitions per night. The International Prostate Symptom Score (IPSS) questionnaire was used to assess LUTS severity.

Results

Responses from 1,842 subjects were analyzed. The overall prevalence of LUTS was 83.4%. Storage LUTS (70.1%) were more prevalent than voiding (60.4%) or postmicturition LUTS (38.3%). When nocturia was defined as two or more nocturnal micturitions per night, voiding symptoms became most prevalent (storage, 39.7%; voiding, 60.4%; and postmicturition, 38.3%). More than 90% of our population described the severity of their urinary symptoms as moderate (8-19) or severe (20-35). The prevalence and severity of LUTS increased with age.

Conclusions

LUTS are highly prevalent among Korean men, and its prevalence increases with age. Increased public awareness and a larger number of treatment options are needed to appropriately manage symptoms and their consequences.

Project description:BackgroundIn men aged above 50 yr, lower urinary tract symptoms (LUTS), benign prostate hyperplasia, and prostate cancer are common urological conditions. Current guidelines for general practitioners frequently recommend prostate-specific antigen (PSA) testing in patients with LUTS for the detection of prostate cancer.ObjectiveTo assess the performance of PSA, PSA density, and the Stockholm3 blood test for identification of prostate cancer among men with LUTS.Design setting and participantsIn this post hoc analysis of a population-based diagnostic trial (STHLM3, n = 58 588), 4588 men aged 50-69 yr, without previous prostate cancer, with International Prostate Symptom Score (IPSS) data, and having PSA ≥ 3 ng/mL were identified. Men with at least moderate LUTS, defined as an IPSS score of ≥8, were included. PSA density and Stockholm3 scores were calculated.InterventionParticipants underwent 10-12-core systematic prostate biopsies.Outcome measurements and statistical analysisThe primary outcome was significant prostate cancer (sPCa) defined as International Society of Urological Pathology (ISUP) grade ≥2. Logistic regression analysis adjusted for age and previous biopsy status was performed. The area under the receiver operating characteristic curve (AUC) was calculated, and decision curve analysis was performed.Results and limitationsOut of 4588 men, 1544 (34%) reported at least moderate LUTS. The median age was 64 yr, and 11% had undergone a previous prostate biopsy. The Stockholm3 test showed superior discrimination for sPCa to PSA density, which in turn showed superior discrimination to PSA (AUC 0.77 vs 0.70 vs 0.61, p < 0.02). Calibration of the Stockholm3 test was adequate. Performing biopsy only in men with PSA ≥5 ng/mL saved 64% of biopsies, but resulted in missing 52% of detectable sPCa. Recommending biopsy for men with PSA density ≥0.07 resulted in sparing 26% of biopsy procedures and delaying the diagnosis of 12% of sPCa cases, with a 6.1% risk of sPCa among unbiopsied men. Recommending men with Stockholm3 ≥ 0.11 for biopsy resulted in sparing 53% of biopsy procedures and delaying the diagnosis of 20% of sPCa cases, with a 5.1% risk of finding sPCa in unbiopsied men.ConclusionsPSA density and the Stockholm3 blood test were superior to PSA for the identification of prostate cancer among men with LUTS.Patient summaryIn this analysis of a large Swedish study, we find that the use of prostate-specific antigen (PSA) density or the Stockholm3 blood test instead of only PSA might improve the detection of prostate cancer among men with lower urinary tract symptoms.

Project description:INTRODUCTION:Dipstick urinalysis is a widely used screening tool in the evaluation of men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). As limited data support the use of dipstick urinalysis, we have used data from three recently published studies to assess clinical outcomes in those who had dipstick urinalysis findings for blood, glucose, and/or leukocytes. METHODS:We analyzed data from three observational studies involving men interested in using over-the-counter tamsulosin: a self-selection study (SSS) and two actual-use studies of 8-week (AUS8) and 24-week (AUS24) durations. Subgroup analyses focused on pooled data from participants not using α-blockers or other prescription medication for LUTS suggestive of BPH (nonRx users) and who had urine dipstick findings. Data from participants using α-blockers (AUS8) or any prescription BPH medications (SSS and AUS24) are presented as reference. RESULTS:Overall, 2488 nonRx users underwent dipstick urinalysis and 680 (27.3%) had positive findings including traces of blood (332; 13.3%), glucose (259; 10.4%), and/or leukocytes (245; 9.8%). Among users of prescription medicines, 21.6% (37/171) in SSS, 27.4% (23/84) in AUS8, and 31.1% (47/151) in AUS24 had urine dipstick findings. The 200 dipstick-positive nonRx users in SSS underwent per protocol urological assessment: 26 (13.0%) had a newly diagnosed condition causing/contributing to urinary symptoms of which 2.9% were identified as medically important conditions. Among nonRx users with or without a dipstick finding, medically important conditions reported included prostate cancer (1.0% vs. 1.0%, respectively) and urolithiasis (1.0% vs. 0.3%, respectively). The proportion of men with dipstick urinalysis findings was similar between men who regularly visited their physician and those who did not. CONCLUSION:Dipstick urinalysis did not markedly increase the detection of undiagnosed medically important conditions that cause/contribute to urinary symptoms, suggesting that this test may not be a very effective screening tool for men with LUTS.

Project description:ObjectiveTo evaluate the effectiveness of self management as a first line intervention for men with lower urinary tract symptoms.DesignRandomised controlled trial.SettingA teaching hospital and a district general hospital in London.Participants140 men (mean age 63 (SD 10.7) years), recruited between January 2003 and April 2004, referred by general practitioners to urological outpatient departments with uncomplicated lower urinary tract symptoms.InterventionsSelf management and standard care (n=73) or standard care alone (n=67). The self management group took part in three small group sessions comprising education, lifestyle advice, and training in problem solving and goal setting skills.Main outcome measuresThe primary outcome measure was treatment failure measured at 3, 6, and 12 months. Symptom severity (international prostate symptom score; higher scores represent a poorer outcome) was used as a secondary outcome.ResultsAt three months, treatment failure had occurred in 7 (10%) of the self management group and in 27 (42%) of the standard care group (difference=32%, 95% confidence interval 18% to 46%). Corresponding differences in the frequency of treatment failure were 42% (27% to 57%) at six months and 48% (32% to 64%) at 12 months. At three months, the mean international prostate symptom score was 10.7 in the self management group and 16.4 in the standard care group (difference=5.7, 3.7 to 7.7). Corresponding differences in score were 6.5 (4.3 to 8.7) at six months and 5.1 (2.7 to 7.6) at 12 months.ConclusionsSelf management significantly reduced the frequency of treatment failure and reduced urinary symptoms. Because of the large observed benefit of self management, the results of this study support the case for a large multicentre trial to confirm whether self management could be considered as first line treatment for men with lower urinary tract symptoms.Trial registrationNational Research Register N0263115137; Clinical trials NCT00270309 [ClinicalTrials.gov].
