Abstract
INTRODUCTION A positive association between benign prostate hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and metabolic syndrome (MetS) was reported in several studies, but studies from Asia often showed conflicting results. MATERIALS AND METHODS Medical records were obtained from a health promotion center database between 2021 and 2022. Men without a history of treatment for LUTS were evaluated using the International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), transrectal ultrasonography. RESULTS Of 1345 individuals, 603 (44.8%) had MetS. Older age, higher IPSS values, higher prevalence rates of BPH and overactive bladder, higher triiodothyronine, and lower testosterone and sex-hormone binding globulin were observed in individuals with MetS than in individuals without MetS. The severity of LUTS significantly increased in the individuals with MetS (p = .002). In individuals with MetS, age, HbA1c, and cerebrovascular disease (CVD) were associated with IPSS. For OABSS, age, HbA1c, thyroid-stimulating hormone (TSH), coronary artery occlusive disease, and CVD were identified as predictors. CONCLUSIONS We confirmed the positive correlation between MetS and BPH/LUTS in Korean. Factors including TSH and atherosclerosis affected LUTS in individuals with MetS. These findings suggested a potential role of thyroid hormones and atherosclerosis in the etiology and treatment of BPH/LUTS in patients with MetS.

Abstract
BACKGROUND Benign Prostatic Hyperplasia (BPH) is considered the most common cause of lower urinary tract symptoms in men aged 40 years and older. BPH is related to sex steroids, but there are increasing studies investigating the relationship between the urinary symptoms and the metabolic syndrome. They still have inconsistent results; some reported a significant positive association, while others found no significant association. In this study, we aim to assess the prevalence rate of metabolic syndrome in BPH patients and whether there is an association between symptoms linked to BPH and metabolic syndrome in the Syrian community. METHODS The participants of this observational cross-sectional study were benign prostatic hyperplasia patients aged 40-year-old and older from Homs, Syria. An interview questionnaire was performed to collect data from all patients who visited the urology clinic of Homs Military Hospital in the period of January 10 to March 10, 2023. We used the International Prostate Symptom Score (IPSS) to assess the urinary symptoms, and we used the US National Cholesterol Education Program Adult Treatment Panel (NCEP ATPIII) criteria to define the metabolic syndrome. RESULTS The final sample size was 426 patients. The overall prevalence of metabolic syndrome was 46.2%. Patients with metabolic syndrome had higher International Prostate Symptom Score compared to patients without metabolic syndrome (21 vs. 18, P < 0.001), and 59.3% of patients with metabolic syndrome suffered from severe symptoms compared to 36.2% of patients without metabolic syndrome who suffered from severe lower urinary tract symptoms (P < 0.001). There was a positive association between (waist circumference, diabetes, triglycerides) (P < 0.001), HDL (P = 0.014) and higher International Prostate Symptom Score. However, there was no statistically significant association between blood pressure and International Prostate Symptom Score (P = 0.879). CONCLUSION Our results showed that patients with metabolic syndrome had a higher International Prostate Symptom Score. This idea should be used to design a new benign prostatic hyperplasia/lower urinary tract symptoms treatment.

Abstract
Background: Prostatic growth has been thought to be the systemic manifestation of some metabolic derangements in recent studies. Nonalcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome, might be closely linked with benign prostate hyperplasia and lower urinary tract symptoms (BPH/LUTS). Several studies have been conducted regarding NAFLD and BPH/LUTS association. However, the results are yet to reach a clear conclusion. We aimed to gather these studies' results to make a more robust analysis through a systematic review and meta-analysis. Methods: We systematically searched Pubmed-Medline, Cochrane Library, and Science Direct databases. We excluded all experimental studies, case reports, and reviews. Our search was restricted to the English language. We used standard mean difference for BPH/LUTS-related parameters. We identified the study qualities by the Newcastle-Ottawa Scale. We conducted a publication bias analysis. Results: A total of six studies involving 7089 participants fulfilled the inclusion criteria. Our meta-analysis revealed that patients with NAFLD have larger prostate volume [0.553 (0.303-0.802), P ˂ 0.001; Q = 97.41; P-value for heterogeneity = P < 0.0001; I2 = 94.86%]. However, the summary effect size of the other parameters of BPH/LUTS (prostate-specific antigen and international prostate symptom score) computed in our meta-analysis did not yield significant results. Conclusions: The prostate size was larger in patients with NAFLD, but the meta-analysis did not reach a significant result for LUTS among the studies. These results should be tested with well-designed studies, in particular, to clarify the association of LUTS with NAFLD.

Abstract
Preclinical and human studies on the relationship between obesity/metabolic syndrome (MetS) and lower urinary tract dysfunction (LUTD) are inconsistent. We compared the temporal effects of feeding four different diets used to induce obesity/MetS, including 60% fructose, 2% cholesterol +10% lard, 30% fructose + 20% lard, or 32.5% lard diet, up to 42 wk, on metabolic parameters and bladder function in male Sprague-Dawley rats. Rats fed a 30% fructose + 20% lard or 32.5% lard diet consumed less food (grams), but only the 32.5% lard diet group took in more calories. Feeding rats a 60% fructose or 30% fructose + 20% lard diet led to glucose intolerance and increased blood pressure. Higher body weight and increased cholesterol levels were observed in the rats maintained on a 2% cholesterol +10% lard diet, whereas exposure to a 32.5% lard diet affected most of the above parameters. Voiding behavior measurement showed that voiding frequency and the total voided volume were lower in the experimental diet groups except for the 30% fructose + 20% lard group. The mean voided volume was lower in the 30% fructose + 20% lard and 32.5% lard groups compared with the control group. Cystometric analysis revealed a decreased bladder capacity, mean voided volume, intermicturition interval, and compliance in the 32.5% lard diet group. In conclusion, experimental diets including 60% fructose, 30% fructose + 20% lard, or 2% cholesterol + 10% lard diet differently affected physiological and metabolic parameters and bladder function to a limited extent, while exposure to a 32.5% lard diet had a greater impact.

Abstract
Background Benign prostatic hyperplasia (BPH) is a disease that causes lower urinary tract symptoms (LUTS), which are the most common urological problem in approximately one-third of the male population aged over 50 years. Some studies have suggested that diabetes may be a risk factor for the development of BPH. However, whether diabetes aggravates the LUTS of BPH patients is still controversial. Aim To investigate the impact of diabetes mellitus on LUTS in BPH patients. Methods A literature search was conducted using Web of Science, Embase, PubMed, and China National Knowledge Infrastructure literature databases. This meta-analysis was registered in PROSPERO (registration number: CRD 42020200794). Fixed- or random-effects models were used for analysis according to heterogeneity. The results of the systematic analysis are presented as weighted mean difference (WMD) with the corresponding 95% confidence intervals (CI). Results In total, 1308 studies were retrieved from databases and 18 articles comprising 1685 cases and 4653 controls were selected for meta-analysis. The results of the meta-analysis showed that the International Prostate Symptom Score (IPSS) value and prostate volume of BPH patients with diabetes was significantly higher than that of BPH patients without diabetes. Conclusions This systematic review is the first to evaluate the impact of diabetes mellitus on LUTS in BPH patients. The results of our meta-analysis support the hypothesis that LUTS in BPH patients is increased in patients with diabetes mellitus compared with controls, which suggests that physicians should pay more attention to BPH patients with diabetes mellitus.

Abstract
BACKGROUND Studies evaluating the relationship between metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) in men with benign prostate hyperplasia (BPH) are lacking in Indonesia. This study aimed to discover the association of LUTS and MetS in men with BPH.
METHODS Subjects who underwent biopsy were recruited from Cipto Mangunkusumo Hospital, Jakarta, Indonesia from January 2014 to January 2018, but only men who had biopsy-proven BPH were included. Body mass index, waist circumference, fasting blood glucose, triglyceride, high-density lipoprotein, prostate volume (PV), and international prostate symptom score (IPSS) were collected before the biopsy. MetS criteria were based on the National Cholesterol Education Program Adult Treatment Panel III. IPSS was assessed for LUTS and consisted of irritative and obstructive symptoms and quality of life (QoL). Independent t-test or Mann–Whitney test was used to analyze numerical data.
RESULTS Of 227 men with biopsy-proven BPH, 87 (38.3%) were diagnosed with MetS. PV was similar in men with or without MetS (54.4 [20.3–100] versus 49.9 [19.5–100] cm3, p = 0.239). Men with MetS generally had more LUTS (15 [1–30] versus 11 [0–35], p = 0.005), more irritative symptoms (8 [0–20] versus 6 [0–20], p = 0.007), and lower QoL (4 [0–6] versus 3 [0–6], p = 0.018).
CONCLUSIONS BPH patients with MetS had greater LUTS, particularly irritative symptoms and QoL score.

Abstract
Background To investigate the association between lower urinary tract symptoms suggestive of benign prostate hyperplasia (LUTS/BPH) and metabolic syndrome (MetS) in aging Chinese males. Methods A dataset that included 3,568 non-MetS cases and 1,020 MetS cases (after data cleansing) was downloaded from the China Health and Retirement Longitudinal Study (CHARLS). To balance the intergroup covariates, propensity score matching (PSM) was employed in the analyses. Univariate logistic regression and multivariate logistic regression were then performed to investigate the relationship between LUTS/BPH and MetS in aging Chinese males. Results Before PSM, multivariate logistic regression showed that participants with MetS had a 1.47 times higher risk of LUTS/BPH compared to non-MetS cases in the final model (P<0.001). It also revealed that participants with low high-density lipoprotein (HDL), abdominal adiposity, or high triglycerides had a higher probability of LUTS/BPH [odds ratio (OR) =1.56 for low HDL; OR =1.50 for abdominal adiposity; and OR =1.48 for high triglyceride, P<0.001], while participants with hyperglycemia or hypertension had identical odds of LUTS/BPH (P>0.05). After PSM, 1,000 pairs were successfully matched. It was also found that MetS cases had a 1.60 times higher risk of LUTS/BPH compared to non-MetS cases (P<0.001), and participants with low HDL, abdominal adiposity, high triglycerides, or hyperglycemia had a higher likelihood of LUTS/BPH than their counterparts (P<0.001). However, the probability of LUTS/BPH in hypertensive patients remained similar to that in non-hypertensive patients (P>0.05). Conclusions Aging Chinese males with MetS had a higher probability of LUTS/BPH. Also, patients with low HDL, abdominal obesity, high triglycerides, or hyperglycemia had an increased risk of LUTS/BPH; however, this was not the case for hypertensive patients.

Abstract
BACKGROUND Metabolic syndrome (MetS) is defined by at least three of the following five criteria: blood pressure ⩾130/85 mmHg, fasting blood glucose ⩾5.6 mmol/l, triglycerides concentration ⩾1.7 mmol/l, waist circumference ⩾102 cm (for men), and high-density lipoprotein cholesterol concentration <1.03 mmol/l (for men). MetS has been associated with worse lower urinary tract symptoms (LUTS) and higher International Prostate Symptom questionnaire scores. MATERIALS AND METHODS MEDLINE, Cochrane, ClinicalTrials.gov, and SCOPUS were critically appraised for all peer-reviewed manuscripts that suitably fulfilled our protocol's inclusion criteria established a priori. Meta-analytical and meta-regression calculations were performed in R using the Sidik-Jonkman and Hartung-Knapp random effects model and predefined covariates. RESULTS A total of 70 studies (n = 90,206) were included in qualitative synthesis. From these, 60 studies focused on MetS and LUTS: 44 reported positive correlations, 5 reported negative correlations, 11 reported no association, and 10 studies focused on MetS and total prostate volume (TPV). MetS positively correlated with moderate LUTS [odds ratio (OR) = 1.56, 95% confidence interval (CI) = 1.35-1.80], severe LUTS (OR = 2.35, 95% CI = 1.82-3.03), overactive bladder (OAB; OR = 3.2, 95% CI = 1.6-5.8), and nocturia severity (OR = 2.509, 95% CI = 1.571-4.007) at multivariate analysis. A total of 30 studies (n = 22,206) were included in meta-analysis; MetS was significantly associated with higher TPV (mean differences = 4.4450 ml, 95% CI = 2.0177-6.8723), but no significant predictive factors for effect sizes were discovered. CONCLUSION Our meta-analysis demonstrates a significant association between the aggravating effects of MetS, which commonly coexists with obesity and benign prostate enlargement.

Abstract
Men ignore self-care, displaying low frequency in health services. Aging increases the prevalence of LUTS and BPE, impacting the quality of life. The objective is to understand how the advancement of age can be determinant for men's health in Natal, Brazil. Then, 503 men aged between 43 and 83 attended the Blue November Campaign of 2015. All subjects were submitted to anamnesis, clinical and laboratorial evaluation including measuring their blood pressure, waist circumference, glucose, total cholesterol, HDL-C, LDL-C, triglycerides and BMI was calculated. In addition, IPSS, PSA, IIEF-5 and DRE data were collected. The mean IPSS presented an increase with age, 43-59 years (6.28 ± 6.02) and 70-80 years or more (8.65 ± 5.80). PSA dosages increase with aging (adult group 1.63 ± 2.70), being more accentuated in the older group (4.66 ± 5.70), while the mean IIFE-5 showed a decrease with aging in 43-59 years (21.79 ± 4.67) and an important decrease at 70-80 years or more (16.24 ± 6.71). The number of DRE > 30 g showed significant growth in the older group. All presented statistical significance (p < .05) and were associated with aging. The Blue November Campaign creates an annual self-care opportunity for aging men as their health is gradually affected.

Abstract
OBJECTIVE We performed this meta-analysis to assess the association between metabolic syndrome (MetS) and benign prostatic hyperplasia (BPH). METHOD We conducted extensive searches on the PubMed, Science and Cochrane Library to identify all articles. Outcomes including annual prostate growth rate, prostate volume (PV), International Prostate Symptom Score (IPSS), IPSS sub-scores (voiding and storage), prostate- specific antigen (PSA), maximum urine flow rate (Qmax), post-void residual urine volume (PVR) and quality of life (QoL) were assessed. RESULTS 21 studies with 15,317 patients were included. Patients with MetS had higher annual prostate growth rate [weighted mean difference (WMD) = 0.79; p < .001], larger PV (WMD = 2.62; p < .001), lower Qmax (WMD = -0.48; p = .001) and more PVR (WMD = 8.28; p < .001). However, no significant differences were found between two groups in IPSS (WMD = 0.20; p = .37), IPSS-voiding (WMD = -0.05; p = .78), IPSS-storage (WMD = -0.22; p = .26), PSA (WMD = 0.04; p = .43), and QoL (WMD = -0.01; p = .70). CONCLUSIONS The study suggested that MetS may be one of the risk factors for the clinical progress of BPH. However, further study is warranted to support these results.

Abstract
The prospective study is to investigate the associations between serum testosterone levels and LUTS among middle-aged men ≥40 years receiving health check-up. Lower urinary tract symptoms were evaluated by the self-administered International Prostate Symptom Score questionnaire. Serum prostate specific antigen and total testosterone level were checked in all subjects. A total of 1752 men were enrolled into the study. The mean age was 55.6 ± 9.7 years. All study subjects were stratified into low, medium and high testosterone levels by two cut-off, 3.0 and 4.11 ng/mL. We found that testosterone levels were significantly associated with metabolic syndrome and body fat components. Compared to those with low testosterone levels, subjects with high and medium testosterone had a significantly higher IPSS (5.84 ± 5.55 vs 6.71 ± 5.68 and 6.34 ± 5.66, p = 0.032) and storage score (2.76 ± 2.29 vs 3.20 ± 2.49 and 2.90 ± 2.49; p = 0.009), and a more moderate/severe LUTS (IPSS ≧ 8) (26.5% vs 35.7% and 29.9%; p = 0.002). Multivariate analyses showed that high vs low testosterone levels (OR, 1.76; 95% CI, 1.26–2.45) and prostate volume ≧25 vs <25 mL (OR, 1.38; 95% CI, 1.04–1.82) significantly associated with the presence of moderate/severe LUTS. Pearson correlation analyses showed significantly positive correlations between testosterone level and IPSS in whole study sample (Pearson correlation coefficient, 0.066; p < 0.01) and in the subgroup of moderate/severe LUTS (Pearson correlation coefficient, 0.038; p < 0.05). In conclusion, high testosterone and prostate volume adversely impacted LUTS in our target population.

Abstract
INTRODUCTION Contemporary studies examine the connection of Diabetes Mellitus (DM) with Lower urinary tract symptoms (LUTS), alone or associated with other factors of the metabolic syndrome. However, little research has occurred concerning patients with diabetes of both genders and sexes without other diseases of the lower urinary tract. The aim of this study is to examine the relationship between DM and LUTS. METHODS The study enrolled 110 patients with DM and 134 healthy individuals. The IPSS questionnaire was used for the evaluation of symptoms from lower urinary tract. Data was analyzed with univariate and multivariate logistic regression using SPSS v.24. RESULTS Analysis with moderate/severe LUTS as dependent variable and plausible confounding factors (age group, BMI, hypertension, dyslipidemia, years with DM and reported HbA1c) as covariates revealed that only HbA1c levels correlated independently with the presence of moderate/severe LUTS (p = 0,024, OR:2,729, CI:1,144-6,509) in diabetic women, while there was no statistically significant difference between male groups. HbA1c levels' correlation with IPSS-voiding and IPSS- storage score was not statistically significant. Quality of life is also affected in women with diabetes mellitus (p: 0,02). CONCLUSION Only an increase in HbA1c was independently connected with a deterioration of LUTS in the female group.

Central obesity indicating a higher prevalence of lower urinary tract symptoms: A case-control matching analysis from a Chinese cross-sectional study in males. Low Urin Tract Symptoms 2018; 11:O135-O140. [PMID: 29971968 DOI: 10.1111/luts.12231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2018] [Revised: 05/04/2018] [Accepted: 06/04/2018] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The aim of this study was to explore the association between central obesity and lower urinary tract symptoms (LUTS) among men in southern China, and test the hypothesis that central obesity measured by the waist-to-hip ratio (WHR) is a predictor of the severity of LUTS. METHODS In all, 4303 men from the Fangchenggang Area Male Healthy and Examination Survey (FAMHES) were included in this study. LUTS were assessed by the International Prostate Symptom Score (IPSS), whereas central obesity was evaluated by the WHR. The association between WHR and LUTS was tested using logistic and Cox regression analyses. RESULTS After screening, 2917 participants were in the study. Univariate analysis indicated significant differences in WHR in the presence of LUTS (P = .012). After stratification by age, logistic regression indicated that LUTS were more frequent in 60-year-old men with a higher WHR (odds ratio [OR] 2.89, 95% confidence interval [CI] 1.21-6.89) compared with participants <40 years old. Cox regression analysis after pairing of 252 LUTS cases and 252 control subjects from the 2917 eligible participants according to age (±5 years), indicated that central obesity (WHR ≥0.9) may be significantly associated with moderate or severe LUTS (OR 1.95, 95% CI 1.16-3.26). The associations between central obesity and straining (OR 2.44, 95% CI 1.40-4.24) and weak stream (OR 2.37, 95% CI 1.27-4.45) were significant after multivariate adjustment. CONCLUSIONS Males with central obesity are at increased risk of LUTS, and increased WHR is associated with worsened straining and weak stream. Further investigations are needed to confirm these associations.

Traish AM, Johansen V. Impact of Testosterone Deficiency and Testosterone Therapy on Lower Urinary Tract Symptoms in Men with Metabolic Syndrome. World J Mens Health 2018; 36:199-222.

Abstract
Lower urinary tract function is modulated by neural, vascular and urethral and bladder structural elements. The pathophysiological mechanisms of lower urinary tract symptoms (LUTS) encompass prostate enlargement, alterations in urethra histological structure bladder fibrosis and alterations in pelvic neuronal and vascular networks, The complex pathophysiological relationship between testosterone (T) deficiency (TD) and the constellations LUTS, and metabolic dysfunction manifested in the metabolic syndrome (Met S) remains poorly understood. TD has emerged as one the potential targets by which Met S may contribute to the onset and development as well as worsening of LUTS. Because it has been recognized that treatment of men with Met S with T therapy ameliorates Met S components, it is postulated that T therapy may represent a therapeutic target in improving LUTS. Furthermore, the effect of TD on the prostate remains unclear, and often debatable. It is believed that T exclusively promotes prostate growth, however recent evidence has strongly contradicted this belief. The true relationship between benign prostatic hyperplasia, TD, and LUTS remains elusive and further research will be required to clarify the role of T in both benign prostatic hypertrophy (BPH) and LUTS as a whole. Although there is conflicting evidence about the benefits of T therapy in men with BPH and LUTS, the current body of literature supports the safety of using this therapy in men with enlarged prostate. As the population afflicted with obesity epidemic continues to age, the number of men suffering from Met S and LUTS together is expected to increase.

Abstract
Although the exact nature of the association between metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) is still not completely understood, findings that men with metabolic alterations experience faster-developing LUTS or are more frequently candidates for benign prostatic enlargement (BPE) surgery support the hypothesis that metabolic and pathological derangements characterizing MetS can promote the development and progression of BPE and LUTS. The strong evidence that MetS is associated with larger prostate size supports a role for metabolic derangements in the development and progression of BPE. However, the relationship between MetS and LUTS is currently based on conflicting results. Most of the US and European population-based studies demonstrate a positive association between MetS and LUTS, but Asian studies often show opposite results. These findings indicate that ethnicity, diet and lifestyle could represent a central issue for the association between MetS and LUTS. PATIENT SUMMARY The strong evidence that metabolic syndrome is associated with greater prostate size supports a role for metabolic derangements in the development and progression of benign prostatic enlargement. Ethnicity, diet, and lifestyle could represent central issues for the association between metabolic syndrome and lower urinary tract symptoms.

Abstract
There has been no previous population-based study reporting the prevalence and risk factors of male lower urinary tract symptoms (LUTS) among men in mainland China. This cross-sectional study was conducted from 2013 to 2014 in three representative provinces of China: Guangdong, Hubei and Jiangsu. 3250 individuals participated in the interviews, which involved a questionnaire covering sociodemographic characteristics, lifestyle, dietary patterns and the International Prostate Symptom Score (IPSS). Blood was collected for lipids, glucose, insulin and reproductive hormone tests. The incidences of LUTS and its obstructive and irritative symptoms were calculated. Risk factors for LUTS were identified using multivariable logistic regression analysis. The prevalence of moderate to severe LUTS and its obstructive and irritative symptoms was 14.3%, 13.1% and 16.1%, respectively, and increased with age. The prevalence in Guangdong was much lower than that in Hubei and Jiangsu in different ages. Increased fasting plasma glucose and decreased HDL-C levels were associated with an increased risk of moderate to severe LUTS (OR = 1.30, 95% CI: 1.02–1.65 and OR = 2.06, 95% CI: 1.08–3.94, respectively). Free testosterone < 0.22 ng/ml decreased the risk of moderate to severe LUTS and obstructive and irritative symptoms by about 20–30%. An inadequate daily intake of vegetables, fruit and water significantly increased the risk of LUTS by 1.3–to 2.0 times. In conclusion, the prevalence of LUTS in Chinese men is high and increases with age. Dietary patterns may be critical for the development of LUTS. Thus, dietary modifications could be a useful strategy for preventing the development of LUTS.

Abstract
OBJECTIVES To estimate the frequency of metabolic syndrome (MetS) in a daily urology practice and to determine its association with lower urinary tract symptoms (LUTS) and erectile dysfunction (ED). MATERIAL AND METHODS A retrospective study was conducted. Data from all male patients aged ≥40 years who attended our outpatient urology clinic from 2010 to 2011 was collected. Prevalence of MetS was determined, and LUTS and ED were assessed. A logistic model was used to determine possible associations, controlling for confounders and interaction factors. RESULTS A total of 616 patients were included. MetS was observed in 43.8% (95% CI 39.6-48.3). The bivariate model showed an association between MetS and LUTS (p<0.01), but not between MetS and ED. The logistic model showed an association between MetS and the International Prostate Symptom Score (IPSS), while controlling for other variables. Patients exhibiting moderate LUTS had a greater risk for MetS than patients with mild LUTS (OR 1.83, 95% CI 1.14-2.94). After analyzing for individual components of MetS, positive associations were found between diabetes and severe LUTS (OR 1.3, 95% CI 1.24-7.1), and between diabetes and ED (OR 2.57, 95% CI 1.12-5.8). CONCLUSION This study was able to confirm an association between MetS and LUTS, but not for ED. Specific components such as diabetes were associated to both. Geographical differences previously reported in the literature might account for these findings. Given that MetS is frequent among urological patients, it is advisable that urologists actively screen for it.

Abstract
Metabolic syndrome (MetS) is a cluster of metabolic abnormalities related to central adiposity and insulin resistance. Its importance is increasingly recognized as it associates with increased risks of metabolic and cardiovascular diseases. These metabolic aberrations of MetS may lead to development of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) in men. A 26.5%-55.6% prevalence of MetS in men with LUTS was reported in worldwide studies. Although the exact biological pathway is not clear yet, insulin resistance, increased visceral adiposity, sex hormone alterations and cellular inflammatory reactions played significant roles in the related pathophysiological processes. Clinician should recognize the cardiovascular and metabolic impacts of MetS in men with LUTS, early risk factors optimization and use of appropriate medical therapy may possibly alter or slower the progression of LUTS/BPH, and potentially avoid unnecessary morbidities and mortalities from cardiovascular and metabolic diseases for those men.

Abstract
PURPOSE OF REVIEW The metabolic syndrome (MetS) is an ever growing pandemic consisting of a constellation of abnormalities. Many hypotheses have been put forth to establish a link between this syndrome and voiding dysfunction. We created a layout of the possible, probable, and proven relationships connecting the MetS with voiding dysfunction in men. RECENT FINDINGS There has been growing interest in the relationship linking MetS and voiding dysfunction, with or without benign prostatic hyperplasia, during the past several years. Different mechanisms have been proposed to establish the connection. SUMMARY A clear-cut association between MetS and voiding dysfunction is not clearly defined; rather, voiding dysfunction occurring in men with MetS has been shown to be related to numerous pathologies. MetS is a complex disease that includes numerous pathophysiological aspects that may contribute to the causation and advancement of voiding dysfunction. In light of this association, future research is needed to better define this relationship to enable therapy targeted against MetS in patients with voiding dysfunction.

Abstract
Metabolic syndrome (MS) is a highly prevalent disease related to the risk of cardiovascular disease and diabetes. A large body of evidence has suggested a link between MS and the components of MS with lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) complex. The pathogenesis of MS is complex and not fully understood. Furthermore, recent results from epidemiological studies, including multiple Asian reports, have not been consistent. The risk of BPH is lower in Asian men compared with white men and the prevalence of MS varies by race and ethnicity. An elevated risk of Type 2 diabetes mellitus, hypertension, and dyslipidaemia is closely related to MS and is observed in Asian men even if their body mass index is low. However, the role of race and ethnic disparity in the link between MS and LUTS secondary to BPH is not elucidated. It has been suggested that the pathogenesis of LUTS is multifactorial rather than developing from BPH, which is the traditional concept. Lifestyle and genetic factors may substantially modify the risk of MS and LUTS/BPH. This comprehensive literature review summarises the scientific evidence of the racial/ethnic disparity regarding the association between MS and LUTS/BPH in order to improve current understanding of this controversial issue.

Abstract
Biologic rationales exist for the associations between metabolic syndrome (MetS) and benign prostatic hyperplasia (BPH). However, epidemiologic studies have yield inconsistent results. The aim of the present study was to prospectively evaluate the associations of MetS with the risk of BPH. The presence of MetS, the number of MetS components, and the individual MetS components were evaluated. After adjusting for potential confounders, MetS was associated with increased risk of BPH (HR: 1.29; 95% CI, 1.08-1.50; p < 0.001). Compared with subjects without any MetS components, the HRs were 0.88 (95% CI, 0.67-1.09; p = 0.86), 1.18 (95% CI, 0.89-1.47; p = 0.29) and 1.37 (95% CI, 1.08-1.66; p = 0.014) for subjects with 1, 2, or ≥3 MetS components, and there was a biologic gradient between the number of MetS components and the risk of BPH (p-trend < 0.001). Central obesity and low high-density lipoprotein cholesterol were the two main divers of the associations between these two conditions, with HRs of 1.93 (95% CI, 1.14-2.72; p = 0.001) for central obesity, and 1.56 (95% CI, 1.08-2.04; p = 0.012) for low HDL-C. Our findings support the notion that MetS may be an important target for BPH prevention and intervention.

Abstract
Epidemiological studies have shown that age is the principal unmodifiable risk factor of lower urinary tract symptoms (LUTS). Until the past decade, the process of lower urinary tract ageing was, therefore, considered unmodifiable - as ageing per se. However, the traditional dogma that BPH-related LUTS (BPH-LUTS) is an immutable consequence of old age is no longer acceptable. Results from multiple preclinical and clinical studies indicate that several modifiable, age-related metabolic aberrations (metabolic syndrome, obesity, dyslipidaemia, diabetes) are important determinants in both the development and the progression of BPH-LUTS. Metabolic syndrome and its related comorbidities, such as sex steroid alterations and low-grade inflammation, have been related to BPH-LUTS development and progression. With the correct treatment and recommended lifestyle changes, many individuals with metabolic syndrome might be able to prevent or delay the onset of metabolic-syndrome-related complications; however, whether promoting healthier lifestyles can really alter a man's propensity to develop BPH-LUTS remains to be clarified.

Abstract
There has been little focus on men's reproductive health (RH) in China. This descriptive study conducted in Yiling District, Yichang, China, surveyed male knowledge of sexual physiology and RH to assess levels of knowledge, attitudes and practices (KAPs) regarding prevention of sexually transmitted diseases (STDs). A total of 3933 men, aged 18–59 years (mean, 40.3 years), were recruited by cluster random sampling. They completed a questionnaire in the presence of an interviewer, with items related to subject characteristics, RH knowledge, and subjective symptoms of the reproductive system. Physical examination and reproductive system disease diagnosis were performed. Participants’ occupations were predominantly skilled labor (80.5%). Nearly four-fifths (78.5%) respondents had at least one reproductive disease. Over half of respondents were aware of and declared a positive attitude about sexual physiology and safe sex, and 70% of them selected to visit a doctor when they had a reproductive disorder. However, only 41.9% believed human immunodeficiency virus/acquired immunodeficiency syndrome could be transmitted through breastfeeding, and 64.6% incorrectly thought they could avoid contracting STDs by cleaning their genitals after intercourse. In addition, 45% discriminated against and were unwilling to be friends with infected persons. Nearly 45% of those with a reproductive system disorder refused to discuss it with friends or family members. These results indicate that this cohort of Chinese men had a certain degree of KAP about RH, whereas some aspects require further public health education in the general population. It is necessary to disseminate accurate knowledge of STD risk in China based on sociodemographic characteristics.

Abstract
The International Consultation on Urological Disease have recently published comprehensive conclusions, based on evidence reviewed by eight committees, on aspects of male lower urinary tract symptoms (LUTS). In this review, we summarise the conclusions from four of the committees, namely, the evidence regarding the epidemiology of male LUTS, patient assessment, nocturia and medical management. It is indisputable that with an expanding and ageing global population the prevalence of male LUTS is likely to increase. Therefore symptom prevention and preservation of quality of life (QoL) feature highly in the guidelines. There are now a number of different medical options, proven to lead to significant improvements in symptom scores, flow rate and QoL available to men with LUTS. Meta-analyses have shown the benefits for alpha blockers, antimuscarinics, 5-α reductase and phosphodiesterase-5 inhibitors. High level evidence also exists for combinations of all of the above with alpha blockers and so men with concomitant storage symptoms, prostate volume > 30 mL, PSA > 1.4 or erectile dysfunction may be considered for combination treatment of an alpha blocker with an antimuscarinic, 5-α reductase inhibitor or phosphodiesterase-5 inhibitor respectively. In an era of personalised medicine, appropriate patient selection is likely to provide the key to the most effective clinical management strategy.

Abstract
The aim of the study was to test the hypothesis that the metabolic syndrome (MS) is linked to lower urinary tract symptoms (LUTS) in Korean men. This was a longitudinal study that used data collected from 328 men aged 50–89 years who were randomly selected among 1,520 participants in 2004. We collected information from 224 (68.3%) men among the original responders on the biological, medical, psychological, social, lifestyle, and economic factors in 2007. The prevalence of the MS was 187/328 (57.0%) in 2004 and 125/224 (55.8%) in 2007 among men, respectively. There was no significantly greater increase in the IPSS in men with the MS than in men without the MS over a 3-year period of time (2.0 ± 9.37 versus 3.0 ± 8.44, p = 0.402, resp.). In the multivariate logistic regression analysis with control for age and life style factors, the risk factors for moderate/severe LUTS were age and erectile dysfunction (p < 0.05). However, the presence of the MS did not increase the risk of moderate/severe LUTS (OR = 1.09, 95% CI 0.63–1.89, p = 0.748). Our cross-sectional and longitudinal risk factor analyses do not support the hypothesis that the MS is linked to LUTS in Korean men.

Abstract
BACKGROUND Metabolic Syndrome (MS) has become a global public health and has been suggested to be a risk factor for Lower Urinary Tract Symptoms (LUTS). Studies evaluating the association between the rate of the MS and LUTS often showed controversial results. OBJECTIVES The purpose of this study was to reveal the relevance of MS and its components on the frequency and severity of the LUTS that were seen with Benign Prostate Hyperplasia (BPH) in Turkish men or not. PATIENTS AND METHODS In this study, 237 patients referred to urology policlinic with BPH were retrospectively scanned between April 2009 and April 2013. Patients with normal digital rectal examination and the Prostate Specific Antigen (PSA) level of ≤ 4 ng/mL were evaluated using the International Prostate Symptom Score (IPSS) and all the data of the patients' body, including Body Mass Index (BMI), lipid parameters, preprandial blood glucose, and waist circumference. Seventy-four patients (31.3%) with mild IPSS (0-7) was group 1; 97 patients (40.9%) with moderate IPSS (8 - 19) group 2 and 66 patients (27.8%) with severe IPSS (20-35) were defined as group 3. group 4 consisted of 117 healthy controls. Three groups and controls were compared about MS and its components. The diagnosis criteria of The Society of Endocrinology and Metabolism of Turkey were used in MS diagnosis. Also, BMI, lipid parameters, preprandial blood glucose, waist circumference, and blood pressure were used as MS parameters. RESULTS The average age of patients in group 1 was 69.8 ± 7.2; in group 2, 69.1 ± 7.4; 68.3 ± 7.1 in group 3 and 70.2 ± 7.2 in the control group. Metabolic syndrome was determined at 37 patients (50%) in group 1, 45 patients (46.5%) in group 2, 32 patients (48%) in group 3 and 52 patients (44.4%) in controls and no statistically significant correlation was detected between LUTS and MS in BPH (P = 0.113). In the comparison of the four groups in the point of MS parameters, no significant correlation was detected in the levels of total cholesterol (P = 0.337), fasting glucose (P = 0.291), BMI (P = 0.452), Low Density Lipoprotein (LDL, P = 0.069) and triglyceride (P = 0.307). CONCLUSIONS In our study, the evidence is not enough to support the hypothesis of the relevance between MS and LUTS. Wide-ranging, prospective and multicentric studies are needed to research the relevance between MS and LUTS in BPH.

Abstract
A significant amount of epidemiological evidences have underlined an emerging link between metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement a (BPE). We aimed to assess the connections between LUTS and MetS with its components. Meta-analysis were conducted to determine the mean differences (MD) and confidence intervals of IPSS total score, IPSS-voiding, IPSS-storage and prostate volume (PV) in patients with or without MetS. Ln(odds-ratio) were calculated to estimate the risk of having moderate-to-severe LUTS (IPSS ≥ 8). Nineteen studies were identified as eligible for this systematic review, with a total of 18,476 participants, including 5554 (30.06%) with and 12,922 (69.94%) without MetS. Pooled analysis did not demonstrate significant MD of IPSS, IPSS-voiding and IPSS-storage in men with or without MetS but PV was significantly different (MD = 2.18; p = 0.03). Presence of MetS was not significantly associated with moderate-to-severe LUTS (odds ratio = 1.13; p = 0.53) and only altered serum triglycerides and diabetes were associated with this risk. The association between MetS and LUTS/BPE remain unclear and further observational studies in a population with metabolic disorders should be conducted in order to address it's potential role in determining LUTS/BPE.

Abstract
Recently, clinical and epidemiologic data indicating the involvement of metabolic syndrome (MetS) in the pathogenesis and progression of lower urinary tract symptom (LUTS)/benign prostatic hyperplasia (BPH) are reported. This review evaluates the reports on the influence of MetS in the development and progression of LUTS/BPH, and discusses possible clinical implications for the management and treatment of this disease. Recent studies on the epidemiological relationship between MetS and LUTS hypothesize that MetS may be associated with an overactivity of the autonomic nervous system for which hyperinsulinemia, a key element of the MetS, might be responsible. An alternative explanation is that LUTS are associated with chronic ischemia of pelvis resulting from atherosclerotic changes in blood vessels, which leads the production of reactive oxygen species, which can damage the bladder detrusor. Control of autonomic nervous system overactivity and control of chronic bladder ischemia have potential as new targets for LUTS treatment. Studies suggest an association of MetS with LUTS/BPH, although further research is needed to understand how MetS influences LUTS/BPH. MetS should be considered a new domain in basic and clinical research in patients with LUTS/BPH and as a target for treatment.

Abstract
Understanding of the role of urothelium in regulating bladder function is continuing to evolve. While the urothelium is thought to function primarily as a barrier for preventing injurious substances and microorganisms from gaining access to bladder stroma and upper urinary tract, studies indicate it may also function in cell signaling events relating to voiding function. This review highlights urothelial abnormalities in bladder pain syndrome/interstitial cystitis (BPS/IC), feline interstitial cystitis (FIC), and nonneurogenic idiopathic overactive bladder (OAB). These bladder conditions are typified by lower urinary tract symptoms including urinary frequency, urgency, urgency incontinence, nocturia, and bladder discomfort or pain. Urothelial tissues and cells from affected clinical subjects and asymptomatic controls have been compared for expression of proteins and mRNA. Animal models have also been used to probe urothelial responses to injuries of the urothelium, urethra, or central nervous system, and transgenic techniques are being used to test specific urothelial abnormalities on bladder function. BPS/IC, FIC, and OAB appear to share some common pathophysiology including increased purinergic, TRPV1, and muscarinic signaling, increased urothelial permeability, and aberrant urothelial differentiation. One challenge is to determine which of several abnormally regulated signaling pathways is most important for mediating bladder dysfunction in these syndromes, with a goal of treating these conditions by targeting specific pathophysiology.

Is metabolic syndrome truly a risk factor for male lower urinary tract symptoms or just an epiphenomenon? Adv Urol 2014; 2014:203854. [PMID: 24587797 PMCID: PMC3920975 DOI: 10.1155/2014/203854] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2013] [Revised: 12/06/2013] [Accepted: 12/07/2013] [Indexed: 11/18/2022] Open
Abstract
To define whether the association of male lower urinary tract symptoms (LUTS) and metabolic syndrome (MS) is real or simply an epiphenomenon, 490 male adults (mean age 58 ± 9 years) underwent International Prostate Symptom Score (IPSS), physical and prostate digital examinations, blood analysis, and urinary tract transabdominal ultrasound with prostate volume measurement. Mild, moderate, and severe LUTS were found in 350 (71.4%), 116 (23.7%), and 24 (4.9%) patients, respectively. MS was present in 198 (40.4%) patients, representing 37.4% (131 of 350) of those with mild LUTS, 46.5% (54 of 116) of those with moderate, and 54.1% (13 of 24) of those with severe. The odds ratio of MS having moderate or severe LUTS was 2.1. MS was more common in older age, higher body mass index, and larger prostate size. Moderate and severe LUTS were more frequent in older age, lower levels of high density cholesterol, and higher blood pressure. Older age and body mass index had significant relative risk for lower urinary tract symptoms and only age remained independent factor for LUTS on multivariate analysis. Our results suggest that the association of male LUTS, prostate volume, and MS might be coincidental and related to older age.

Abstract
OBJECTIVE To evaluate the associations between body mass index (BMI) and prostate volume (PV) and lower urinary tract symptoms in a multiethnic cohort. METHODS A cohort of men without prostate cancer seen at our institution was assembled, excluding those with previous transurethral resection of the prostate. Height and weight were measured to compute BMI, PV was measured by transrectal ultrasound, and the International Prostate Symptom Score (IPSS) questionnaire was administered. After stratified bivariate analyses, multiple linear regression and ordinal logistic regression models were used to assess the independent effect of BMI on PV and IPSS, respectively. RESULTS The cohort included 1613 patients, and mean BMI was 27.1 kg/m(2). Patients with a BMI of <25.0, 25.0-29.9, and 30.0-34.9 had a median PV of 44.0 mL, 48.0 mL, and 52.0 mL, respectively. The African ethnicity subgroup generally had larger median PVs than European and Asian subgroups and had the largest differences in median PV between normal and obese men. There were no significant differences in IPSS or usage of benign prostatic hyperplasia medications between BMI categories. In multivariable analyses, higher BMI was associated with larger PV (P <.001) but not IPSS (P = .91). On the basis of our model, given a PV of 40 mL, 50 mL, and 60 mL, each 5 kg/m(2) increase in BMI was associated with a 2.19 mL, 2.74 mL, and 3.29 mL increase in PV, respectively. Body weight (P <.001) but not height (P = .13) was associated with PV. CONCLUSION Higher BMI is associated with larger PV but not worse lower urinary tract symptoms (measured using IPSS). Usage rate of alpha blockers or 5 alpha reductase inhibitors was not significantly different between BMI categories.

Abstract
OBJECTIVES To investigate the pathological relationship between metabolic syndrome and peri-urethral fibrosis status secondary to chronic prostate inflammation. METHODS Peri-urethral prostate tissue from 80 consecutive patients who underwent retropubic radical prostatectomy for prostate cancer was analyzed. Patients were divided in two groups according to whether or not they had a diagnosis of metabolic syndrome. A 16-peri-urethral core bench biopsy was carried out on each radical prostatectomy specimen to evaluate the extent of peri-urethral inflammatory infiltrate, and collagen and elastin amount. Spearman's correlation analysis was used to test the association between variables. Furthermore, the data were used to define a bivariate logistic regression model in which the presence (>50% collagen amount for each patients) or absence (≤50% collagen amount) of fibrosis was analyzed after adjusting for clinical and pathological variables. RESULTS A significant difference was found between the two groups in terms of International Prostatic Symptoms Score (P < 0.05) and urodynamics findings (all P < 0.05). Patients with metabolic syndrome showed a more extended inflammatory infiltrate and higher peri-urethral collagen amount, along with a lower peri-urethral elastin amount (all P < 0.05). A positive correlation was observed between inflammation, International Prostatic Symptoms Score, Bladder Outlet Obstruction Index and collagen amount, whereas inflammation was inversely correlated with elastin amount. On multivariate logistic regression analysis, prostate inflammation and metabolic syndrome were the only independent predictors of peri-urethral fibrosis (OR 1.73, 1.52, respectively). CONCLUSIONS The present findings suggest that metabolic syndrome might represent an independent risk factor for prostate inflammation and fibrotic changes secondary to inflammation within the peri-urethral prostatic tissue.

Prostate calcification worsen lower urinary tract symptoms in middle-aged men. Urology 2013; 81:1320-4. [PMID: 23561714 DOI: 10.1016/j.urology.2013.02.021] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2013] [Revised: 02/10/2013] [Accepted: 02/12/2013] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To investigate the correlation between prostatic calcification and lower urinary tract symptoms (LUTS) in a sample of middle-aged men receiving health checkups. METHODS Subjects aged 40 years or older who voluntarily underwent transrectal prostate ultrasound (TRUS) and fulfilled International Prostate Symptoms Score (IPSS) as part of their medical checkup were enrolled in this study. The prostatic calcification grading and prostate volume (PV) were measured by TRUS. The medical history, demographics, and metabolic markers were also evaluated. Logistic regression was used to analyze the correlation between prostatic calcification and LUTS. RESULTS A total of 604 men were enrolled as study subjects. The prostatic calcification grading was significantly associated with age and PV instead of metabolic markers. Compared to the nonprostatic calcification group, the moderate/marked prostatic calcification group had a significantly higher age-adjusted IPSS (8.69 vs 6.87, P <.01), quality of life (QOL) score (2.57 vs 2.17, P <.01), storage score (3.74 vs 3.06, P = .01), voiding score (4.95 vs 3.72, P <.01), and more maximum flow rate <15 mL/sec (40.4% vs 24.5%, P <.01). Prostatic calcification grading was positively correlated with age-adjusted IPSS, QOL, voiding, and storage scores (all P for trend <.05). Further multivariate analysis indicated that moderate/marked prostatic calcification was an independent risk factors for moderate to severe LUTS (odds ratio [OR] = 1.68, P = .02). CONCLUSION Prostatic calcification worsened IPSS, QOL, storage, voiding symptoms, and maximum urine flow (Qmax) in middle-aged men receiving a health checkup. Moderate/marked prostatic calcification was an independent risk factor for moderate to severe LUTS.

Abstract
OBJECTIVE To investigate the impact of metabolic syndrome on lower urinary tract symptoms in a sample of middle-aged men receiving a health checkup. METHODS Subjects aged 45 years or older who voluntarily underwent a medical checkup were enrolled. Participant demographics and health history were collected by a self-administered questionnaire. All participants were stratified into 2 groups by the presence of metabolic syndrome, as defined according to the updated National Cholesterol Education Program's Adult Treatment Panel III. Prostate volume and prostate-specific antigen levels were used for subgroup analysis. RESULTS During January through December of 2010, 708 subjects with a mean age of 55.6 ± 9.72 years were enrolled into the study. Compared to the nonmetabolic syndrome group, the metabolic syndrome group had lower total international prostatic symptoms score (7.89 ± 6.63 vs 6.85 ± 6.52, P = .05) and lower severity of weak urinary stream (1.24 ± 1.60 vs 0.95 ± 1.50, P = .021). In the higher prostate volume group (prostate volume ≥ 30 mL), total international prostatic symptoms score, storage score, and urinary frequency, urgency and incomplete emptying were lower in men vs those without metabolic syndrome (all P < .05). The negative association between voiding score, severity of lower urinary tract symptoms, and metabolic syndrome became particularly pronounced as the number of metabolic syndrome factors increased (P for trend < .01). CONCLUSION We confirmed that metabolic syndrome had favorable effects on lower urinary tract symptoms, including voiding and storage symptoms in healthy middle-aged men. This beneficial effect was most significant in men with enlarged prostate and/or high prostate specific antigen levels.

Abstract
PURPOSE To investigate any associations between lower urinary tract symptoms (LUTS)/benign prostate hyperplasia (BPH) and metabolic syndrome (MetS). MATERIALS AND METHODS In all, 1,224 male police officers in their 50s who had participated in health examinations were included. LUTS/BPH was assessed by serum prostate-specific antigen, International Prostate Symptom Score (IPSS), transrectal ultrasonography, maximum urinary flow rate (Q max), and postvoid residual urine volume (PVR). In addition, testosterone was also examined. The MetS was defined using NCEP-ATP III guidelines. We used the multiple linear regression test and logistic regression analyses to examine the relationships. RESULTS MetS was diagnosed in 29.0% of participants. There was no significant difference in the percentage of cases of BPH (IPSS >7, Q max <15 ml/sec, and prostate gland volume ≥ 20 ml) (14.2% in the non-MetS group vs. 17.2 in the MetS group; p value=0.178). The total IPSS score and the Q max were not significantly different. The prostate volume and PVR were significantly greater in the subjects with MetS. After adjusting for age and testosterone, the presence of MetS was not associated with BPH (multivariate odds ratio, 1.122; 95% confidence interval, 0.593~2.120). Additionally, MetS was not related to IPSS (Beta, -0.189; p value=0.819), prostate volume (Beta, 0.815; p value=0.285), Q max (Beta, -0.827; p value=0.393), or PVR (Beta, 0.506; p value=0.837). CONCLUSIONS According to our results, the MetS was not clearly correlated with LUTS/BPH in Korean men in their 50s.

Abstract
OBJECTIVES We investigated the possible changes in lower urinary tract function in mice fed a high fat diet (HFD). METHODS Male C57BL/6J mice were divided into two different feed groups: normal diet (ND) and HFD (n = 16 in each). The body weight, blood glucose level and voiding frequency/volume (FV) relations (for 24 h) were measured every 4 weeks. At 25 weeks old, blood pressure and heart rate, cystometry and isolated detrusor smooth muscle function were measured. After the experiments, serum fat level was measured. RESULTS The body weight and blood glucose level of the HFD group were significantly higher than those of the ND group after 9 weeks old. In the FV measurements, the mean voided volume was not significantly different between the two groups, although voiding frequency, total voided volume and water intake volume in the HFD group were significantly lower than those in the ND group. At 25 weeks old, the mean heart rate in the HFD group was significantly higher than that in the ND group, but no significant difference in the blood pressure was observed. None of the cystometric parameters analyzed showed significant differences between the two groups. The contractile response to either carbachol or high K(+) was not significantly different, whereas the contractile response to electrical field stimulation was significantly higher in the HFD group. In the HFD group, the mean total cholesterol level was significantly higher. CONCLUSION The present results suggest that HFD-feeding for 20 weeks in mice unlikely affects bladder function even though it induced diabetes, hyperlipidemia and tachycardia.

Abstract
This study aimed to evaluate the influence of the lifestyle, prostate volume (PV), and metabolic syndrome (MS) on lower urinary tract symptoms (LUTS) in the elderly males. A total of 764 men aged greater than 40 years were enrolled. Their severities of LUTS were assessed by the International Prostate Symptom Score questionnaire, while their MS was diagnosed according to the criteria developed by the National Cholesterol Education Program Adult Treatment Panel III. Lifestyle factors, PV, and components of MS were compared between no/mild and moderate/severe LUTS groups. In univariate analysis, age, cigarette smoking, alcohol consumption, physical activity, and PV significantly correlated with the severity of LUTS, but the presence or any components of MS did not. Results of multivariate analysis showed that aging, cigarette smoking, lack of regular exercise, and larger PV were independent predictors for moderate/severe LUTS. Notably, the risk factors for LUTS was influenced by the presence of MS. PV may play a role in determining the severity of LUTS for men without MS, while physical activity was the critical factor for men with MS. It was suggested that healthy lifestyle would be beneficial to lessen the severity of LUTS in the elderly males.

Abstract
OBJECTIVE To determine which measurement variable, waist circumference (WC), body mass index (BMI), or waist-to-hip ratio (WHR) is most closely related to the prostate volume (PV), prostate-specific antigen (PSA), and lower urinary tract symptoms (LUTS). METHODS Between January 2010 and September 2011, 1632 consecutive ostensibly healthy Korean men aged 40-69 years who visited our clinic for a prostate checkup were enrolled into the study. Exclusion criteria included pyuria, history of lower urinary tract disorder influencing urination, and a high PSA level of >3.0 ng/mL. All men underwent a detailed clinical evaluation using the International Prostate Symptom Score (I-PSS) questionnaire. Anthropometric measurements were determined. Serum PSA, urinalysis, and transrectal ultrasound were also performed. RESULTS Data from 1601 men were analyzed. The mean age was 51.6 years, WC 83.7 cm, BMI 24.8 kg/m(2), PV 24.6 mL, and the mean PSA level was 1.07 ng/mL. Using multivariate analysis, PV most positively associated with WC (P < .001), while PSA level had negatively associated with BMI (P = .036) and no significant association with WC or WHR was noted. There was no significant relationship between various obesity indexes and I-PSS. CONCLUSION Our data showed that PV positively associated with central obesity, as represented by WC. In contrast, serum PSA negatively associated with BMI, which represented overall obesity (ie, hemodilution). Our data also suggested that obesity is not associated with lower urinary tract symptoms in Korean men.

Abstract
CONTEXT Metabolic syndrome (MetS), a cluster of several metabolic abnormalities with a high socioeconomic cost, is considered a worldwide epidemic. Recent epidemiologic and clinical data suggest that MetS is involved in the pathogenesis and progression of prostatic diseases such as benign prostatic hyperplasia (BPH) and prostate cancer (PCa). OBJECTIVE This review evaluates the available evidence of the role of MetS in BPH and PCa development and progression and discusses possible clinical implications for the management, prevention, and treatment of these diseases. EVIDENCE ACQUISITION A National Center for Biotechnology Information (NCBI) PubMed search for relevant articles published between 1995 and September 2011 was performed by combining the following Patient population, Intervention, Comparison, Outcome (PICO) terms: male, metabolic syndrome, prostate, benign prostatic hyperplasia, prostate cancer, prevention, diagnosis, treatment, and prognosis. Additional references were obtained from the reference list of full-text manuscripts. EVIDENCE SYNTHESIS MetS is a complex, highly prevalent disorder and a worldwide epidemic. Central obesity, insulin resistance, dyslipidemia, and hypertension are the main components of MetS. Notwithstanding all the attempts made to correctly define MetS, a major problem related to most definitions remains the applicability to different populations and ethnic groups. Although there is growing evidence of the association of MetS with the initiation and clinical progression of BPH and PCa, molecular mechanisms and effects on treatment efficacy remain unclear. Further research is required to better understand the role of MetS in BPH and PCa. CONCLUSIONS Data from the peer-reviewed literature suggest an association of MetS with BPH and PCa, although the evidence for a causal relationship remains missing. MetS should be considered a new domain in basic and clinical research in patients with prostatic disorders.

Abstract
OBJECTIVE To investigate the association between severity of lower urinary tract symptoms (LUTS) and metabolic syndrome (MetS) and its components in a large male population in China. METHODS Data were collected from 3103 men attending the Fangchenggang Area Male Healthy and Examination Survey (FAMHES) from September 2009 to December 2009. LUTS were assessed by the International Prostate Symptom Score (IPSS) and MetS were defined using a modification of the Adult Treatment Panel III guidelines. Blood samples were drawn to determine serum lipids and glucose levels. Comprehensive information on demographic characteristics and medication was also collected through questionnaires. The association between LUTS and MetS was presented as odds ratios and 95% confidence intervals estimated using a logistic regression model. RESULTS The presence of MetS was not associated with the severity of LUTS (multivariate OR=0.97, 95% CI=0.67-1.39), but its subcategories of moderate or severe storage symptoms were inversely related to MetS (multivariate OR=0.64, 95% CI=0.44-0.91). Aging was observed to be a major risk factor for LUTS, such that men 60 years or older experienced 2-fold the odds of moderate or severe LUTS (OR=2.79, 95% CI=1.82-4.29) when compared with men 40 years or less). Component of MetS, such as systolic blood pressure, has increased odds for moderate or severe postmicturition symptoms but with no statistically significant results in multivariate analysis (multivariate OR=1.22, 95% CI=0.93-1. 60). CONCLUSIONS Our data suggest that the MetS is not associated with LUTS. However, for subcategory symptoms, decreased odds of MetS was observed in moderate or severe voiding storage symptoms.
