Is Dipstick Urinalysis Screening Beneficial in Men with Lower Urinary Tract Symptoms?

ABSTRACT: 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: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: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].

Project description:BackgroundLower urinary tract symptoms (LUTS) are associated with frailty phenotype, a risk factor for functional decline. Our objective was to determine the association between baseline LUTS and 2-year risk of new functional limitation among older men.MethodsWe analyzed data from the Osteoporotic Fractures in Men (MrOS) study with baseline at Year 7 and follow-up through Year 9. Participants included 2716 community-dwelling men age ≥ 71 years without any baseline self-reported functional limitation. LUTS severity (American Urologic Association Symptom Index) was classified as none/mild (score 0-7), moderate (8-19), and severe (20-35). At baseline and follow-up, men reported their ability to complete several mobility, activities of daily living (ADLs), and cognition-dependent tasks. Risk was estimated for 3 incident functional limitation outcomes: (1) mobility (any difficulty walking 2-3 blocks or climbing 10 steps), (2) ADL (any difficulty bathing, showering, or transferring), and (3) cognition-dependent (any difficulty managing money or medications). We used Poisson regression with a robust variance estimator to model adjusted risk ratios (ARR) and 95% CIs controlling for age, site, and comorbidities; other demographic/lifestyle factors did not meet criteria for inclusion.ResultsOverall, the 2-year risk was 15% for mobility, 10% for ADLs, and 4% for cognition-dependent task limitations. Compared to none/mild LUTS, risk of incident mobility limitations was increased for moderate (ARR = 1.35, 95% CI: 1.12, 1.63) and severe LUTS (ARR = 1.98, 95% CI: 1.48, 2.64). Men were also at higher risk for incident ADL limitations if they reported moderate (ARR = 1.32, 95% CI: 1.05, 1.67) and severe LUTS (ARR = 1.62, 95% CI: 1.07,2.43). Results were somewhat attenuated after adjusting for the frailty phenotype but remained statistically significant. LUTS were not associated with incident cognition-dependent task limitations.ConclusionsLUTS severity is associated with incident mobility and ADL limitations among older men. Increased clinical attention to risk of functional limitations among older men with LUTS is likely warranted.

Project description:Background/objectivesTo estimate associations between lower urinary tract symptoms (LUTS) and phenotypic frailty in older men.DesignCross-sectional study.SettingCommunity-dwelling men recruited from 2000 to 2002 from six U.S. academic centers for the Osteoporotic Fractures in Men Study.ParticipantsA total of 5,979 men aged 65 and older.MeasurementsThe independent variable was LUTS severity (none/mild, moderate, or severe) assessed with the American Urologic Association Symptom Index. Participants were categorized as frail, intermediate stage, or robust using an adapted Cardiovascular Health Study index (components: low lean mass, weakness, exhaustion, slowness, and low physical activity). Associations were estimated with odds ratios and 95% confidence intervals (CIs) from multivariable multinomial logistic regression models adjusted for potential confounders of age, other demographics, health-related behaviors, and comorbidities.ResultsThe prevalence of frailty was 7%, 11%, and 18% among men with none/mild, moderate, and severe LUTS, respectively. Moderate and severe LUTS, overall and by storage and voiding subscores, were associated with higher odds of both intermediate stage and frailty in all models. After adjustment for confounders, the odds of frailty was 1.41 times higher among men with moderate LUTS (95% CI = 1.14-1.74) and 2.51 times higher among men with severe LUTS (95% CI = 1.76-3.55), compared with none/mild LUTS. Severe LUTS was associated with a greater odds of individual frailty components exhaustion and low physical activity.ConclusionThe prevalence of phenotypic frailty is higher among older community-dwelling men with moderate or severe LUTS compared with those with mild or no LUTS. The positive association between LUTS severity and frailty among older men appears independent of age and known frailty risk factors. Although the temporal direction of this association and the utility of LUTS or frailty interventions in this population remain unclear, the high co-occurrence of these conditions could lead to earlier identification of frailty when clinically appropriate.
