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
AIM This study explores the risk of diabetes-associated lower and upper urinary tract diseases among male older adults aged 45 and above in India. METHODS Longitudinal Ageing Study in India (LASI), 2017-2018 data was used in this study. The prevalence of various urinary tract problems and diabetes among male older adults was estimated by background characteristics using bivariate cross-tabulation. In addition, multivariate logistic regression was applied to examine the likelihood of urological disorders associated with diabetes. RESULT The prevalence of incontinence was highest among male older adults with diabetes, followed by kidney stones, benign prostatic hyperplasia, and chronic renal failure. Multivariate logistic regression estimation showed that men diagnosed with diabetes were 80% more likely to experience chronic renal failure, 78% more likely to suffer from incontinence, and 37% more likely to suffer from kidney stones than those without diabetes when controlling for various socio-demographic, behavioral, and co-morbidity status of the older adults. CONCLUSIONS The study findings suggest that diabetes is associated with multiple urinary complications among male older adults in India and needs more careful investigation of the phenomenon. Independent risk factors such as changes in lifestyle with regular monitoring and diagnosis may help to prevent the progression of diabetes and reduce the risk of diabetes-associated lower and upper urinary tract diseases among male older adults.

Abstract
PURPOSE Hypogonadism is associated with a wide range of physical and psychological symptoms that can affect the overall health of men. However, in a developing country, there are several imposing challenges in the diagnosis and treatment of hypogonadism, including a lack of awareness and understanding of the condition among healthcare providers and patients, limited resources and the high cost of treatment. This review aimed to examine the potential benefits and risks of testosterone replacement therapy (TRT) and provides a perspective of a developing country on the topic. MATERIALS AND METHODS A comprehensive literature review was conducted to gather relevant information on the impact of testosterone deficiency on ageing males and the effectiveness of TRT for treating hypogonadism. Published peer-reviewed articles were analyzed to evaluate the benefits and risks of TRT. Additionally, the unique challenges faced in the diagnosis and treatment of hypogonadism in a developing country were considered. RESULTS Testosterone replacement therapy has been shown to be an effective treatment for hypogonadism, particularly in symptomatic men with low testosterone levels. It offers potential benefits such as improvements in symptoms and overall quality of life. However, there are associated risks and side effects that need to be considered. In a developing country, challenges such as limited awareness and understanding of hypogonadism, resource constraints, and high treatment costs pose additional barriers to accessing TRT and comprehensive care. CONCLUSION In conclusion, TRT holds promise as a treatment for hypogonadism, but its implementation and accessibility face significant challenges in a developing country. Addressing these challenges, including raising awareness, allocating resources, and finding cost-effective solutions, is crucial for ensuring that men with hypogonadism in such settings receive appropriate diagnosis and treatment. Further research and efforts are needed to improve the management of hypogonadism in developing countries and optimize the potential benefits of TRT for affected individuals.

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
Nonalcoholic fatty liver disease (NAFLD), the liver component of metabolic syndrome, is considered to be associated with high risk of prostatic diseases but a systematic review has not been conducted. Under a comprehensive review of the eligible clinical studies, a potential positive association between NAFLD and benign prostatic hyperplasia/prostate cancer (BPH/PCa) has been postulated. Insulin resistance and metabolic aberrations are considered to be the potential mechanism for such association. However, the relationship between NAFLD and other prostatic diseases, that is, prostatic inflammation and lower urinary tract symptoms, seems vague due to limited relevant studies in the literatures. The present review highlights that clinicians should be conscious of the detrimental effect of NAFLD on the development of BPH and PCa.

Metabolic syndrome is associated with prostate enlargement: a systematic review, meta-analysis, and meta-regression on patients with lower urinary tract symptom factors. Ther Adv Endocrinol Metab 2021; 12:20420188211066210. [PMID: 34900218 PMCID: PMC8664322 DOI: 10.1177/20420188211066210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Accepted: 10/25/2021] [Indexed: 11/25/2022] Open
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
Benign prostate hyperplasia (BPH), one of the most common diseases in older men, adversely affects quality-of-life due to the presence of low urinary tract symptoms (LUTS). Numerous data support the presence of an association between BPH-related LUTS (BPH-LUTS) and metabolic syndrome (MetS). Whether hormonal changes occurring in MetS play a role in the pathogenesis of BPH-LUTS is a debated issue. Therefore, this article aimed to systematically review the impact of hormonal changes that occur during aging on the prostate, including the role of sex hormones, insulin-like growth factor 1, thyroid hormones, and insulin. The possible explanatory mechanisms of the association between BPH-LUTS and MetS are also discussed. In particular, the presence of a male polycystic ovarian syndrome (PCOS)-equivalent may represent a possible hypothesis to support this link. Male PCOS-equivalent has been defined as an endocrine syndrome with a metabolic background, which predisposes to the development of type II diabetes mellitus, cardiovascular diseases, prostate cancer, BPH and prostatitis in old age. Its early identification would help prevent the onset of these long-term complications.

Abstract
OBJECTIVE To investigate the correlation of clinical measurements on normal and abnormal fasting blood glucose (FBG) with benign prostatic hyperplasia (BPH). METHODS From September 2016 to January 2018, 771 BPH patients were enrolled for further selection. The eligible patients were divided into normal FBG, impaired fasting glucose (IFG), and high risk of type 2 diabetes mellitus (HR-T2DM) groups. Then, relevant parameters were compared among these three groups using Pearson's correlation coefficient. RESULTS Finally including 443 patients with normal FBG, 113 with IFG and 56 with HR-T2DM. Height, weight, body mass index, smoking status, hemoglobin, serum Na+, serum Cl-, and serum Ca2+ were significantly different between normal and abnormal FBG groups. In IFG/HR-T2DM group, obviously connections were demonstrated for weight with prostate volume (PV), for serum Na+, PV, and serum Cl- with total prostate-specific antigen (t-PSA), for FBG with international prostate symptom score (IPSS). In normal FBG group, significant correlations of age, weight, body mass index, hemoglobin, and serum Ca2+ with PV, of age, systolic blood pressure, PV, and serum Cl- with t-PSA; and of FBG, hemoglobin, and serum Na+ with IPSS were also observed. CONCLUSIONS Our study suggests that FBG level probably plays an important role in BPH.

Abstract
BACKGROUND AND OBJECTIVES Evidence has supported obesity as a risk factor for both benign prostate hyperplasia (BPH) and hypogonadism. In this paper, we performed a retrospective study and discussed the prevalence of testosterone deficiency (TD) and its relationship to body mass index (BMI) in aging Chinese men with BPH who have surgical intervention. MATERIAL AND METHODS We reviewed the clinical data by age, BMI, medical history, serum prostate-specific antigen (PSA) levels, serum total testosterone (TT) levels, biochemical analysis, and transrectal ultrasound. BMI and other variables were considered to be independent variables in an effort to evaluate any potential associations between these factors and TD status using non-adjusted and multivariate-adjusted regression models. RESULTS Of the 795 BPH participants, 27.2% (216) patients had TD. After adjusting for all potential covariates, there was a similar J-shaped relationship between BMI and TD, with an inflection point of 19.2 kg/m2. The effect sizes and the confidence intervals on the left and right sides of this inflection point were 0.6 (0.4-1.0) (p = .043) and 1.2 (1.1-1.3) (p < .001), respectively. CONCLUSION Nearly one-third of the aging Chinese BPH patients had TD in this study. The association between BMI and TD is not simple. A J-shaped curve correlation was detected. BMI was positively correlated with TD when it was over 19.2 kg/m2 and inversely correlated with TD when it was below 19.2 kg/m2. Long-term prospective studies are needed to confirm these findings.

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
OBJECTIVES To assess the association between triglyceride (TG)/high density lipoprotein (HDL) ratio and benign prostate hyperplasia/lower urinary tract symptoms (BPH/LUTS). METHODS Four hundred patients who were admitted to the Urology Clinic between January and December 2014 with complaints of BPH/LUTS were enrolled in this cross-sectional study. Patients were divided into two groups according to their International Prostate Symptom Score and prostate volume (PV). They were compared in terms of age, body mass index (BMI), PV, PSA, post micturional residual volume, uroflowmetry Q max value, fasting blood sugar, TG and high density lipoprotein-cholesterol (HDL-C) level and TG/HDL ratio. RESULTS Although univariate analyses reveal that age, BMI, waist circumference (WC), FBS, TG, HDL-C level, and TG/HDL ratio were correlated with PV, only age [1.125 OR (1.088-1.164), p = .00001], BMI [1.119 OR (1.040-1.204), p = .003], TG [(1.043 OR (1.016-1.071), p = .002], HDL-C [(0.923 OR (0.860-0.990), p = .025], and TG/HDL ratio [(1.224 OR (1.130-1.315), p = .014] were statistically significant in multivariate analysis. The calculated area under the curve (AUC) for PV of 30 ml, 40 ml, and 50 ml was 0.668 (0.608-0.727), 0.617 (0.561-0.673), and 0.592 (0.530-0.654), respectively. CONCLUSIONS Our results indicate that the TG/HDL ratio correlates with enhancement in PV. Further studies are warranted to better evaluate this relationship.

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 The prevalence of prostatic inflammation (PI) is very frequent in patients affected by benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). To investigate the relationship between prostatic inflammation (PI) and the presence of MetS and non-alcoholic fatty liver disease (NAFLD) in a cohort of patients affected by BPH/LUTS. METHODS We conducted a prospective study from January 2012 to June 2014 on 264 consecutive patients, who underwent transurethral resection of the prostate for bladder outlet obstruction. Metabolic syndrome (MetS) has been defined according to the International Diabetes Federation (IDF). Prior to surgery, each patient has been evaluated for the presence of MetS and NAFLD. All surgical specimens were investigated for the presence of an inflammatory infiltrate, according to the Irani score. RESULTS The prevalence of patients affected by MetS alone was 13.8% (32/232), 13.8% (32/232) by NAFLD alone, and 42.7% (99/232) by both diseases. The rate of subjects affected by MetS + NAFLD and severe PI was significantly greater than those with only one metabolic alteration (75.8% vs. 24.2%, P < 0.01). The multivariate logistic regression analysis revealed that FLI was independently associated with high PI (Irani score ≥ 4) (odds ratio [OR]: 1.04; P < 0.01). Further, the combination between MetS and NAFLD was associated severe PI (OR: 4.5; P < 0.01) while not MetS as a single alteration. CONCLUSIONS Patients with BPH/LUTS and metabolic aberration exhibited grater PI. The coexistence of MetS and NAFLD exerted a greater detrimental effect on prostate gland by increasing severity of inflammation. Prostate 76:1528-1535, 2016. © 2016 Wiley Periodicals, Inc.

Abstract
Lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) represent one of the most common clinical complaints in adult men. Several drugs used for LUTS/BPO may strongly affect sexual function and bother. The aim of this systematic review and meta-analysis was to evaluate the impact of combination therapy with alpha-blockers (AB), 5-alpha reductase inhibitors (5-ARI) on the risk of erectile dysfunction(ED) and libido alterations (LA) from randomized clinical trial (RCT). Based on the inclusion and exclusion criteria, five RCTs involving 6131 patients were included in the analysis. According to the analysis, the overall prevalence of ED and LA were significantly greater in the combination treatment group than in the AB group (7.93% versus 4.66%; OR 1.81; p < 0.0001 and 3.69% versus 2.36%; OR 1.58; p = 0.003, respectively). The combination therapy increased the risk of ED compared to monotherapy with 5-ARI (7.93% versus 6.47%; OR 1.25; p = 0.04) but not the risk of LA (3.51% versus 3.37; OR 1.03; p = 0.84). In our systematic meta-analysis, we demonstrated that combination therapy with ABs and 5-ARIs was associated with significantly higher risk of ED and LA compared with single monotherapy. Combination therapy showed similar risk of LA compared with 5-ARI monotherapy.

Abstract
BACKGROUND BPH is a common disease associated with age and obesity. However, the biological pathways between obesity and BPH are unknown. Our objective was to investigate biomarkers of systemic and prostate tissue inflammation as potential mediators of the obesity and BPH association. METHODS Participants included 191 men without prostate cancer at prostate biopsy. Trained staff measured weight, height, waist and hip circumferences, and body composition by bioelectric impedance analysis. Systemic inflammation was estimated by serum IL-6, IL-1β, IL-8, and TNF-α; and by urinary prostaglandin E2 metabolite (PGE-M), F2-isoprostane (F2iP), and F2-isoprostane metabolite (F2iP-M) levels. Prostate tissue was scored for grade, aggressiveness, extent, and location of inflammatory regions, and also stained for CD3 and CD20 positive lymphocytes. Analyses investigated the association between multiple body composition scales, systemic inflammation, and prostate tissue inflammation against BPH outcomes, including prostate size at ultrasound and LUTS severity by the AUA-symptom index (AUA-SI). RESULTS Prostate size was significantly associated with all obesity measures. For example, prostate volume was 5.5 to 9.0 mls larger comparing men in the 25th vs. 75th percentile of % body fat, fat mass (kg) or lean mass (kg). However, prostate size was not associated with proinflammatory cytokines, PGE-M, F2iP, F2iP-M, prostate tissue inflammation scores or immune cell infiltration. In contrast, the severity of prostate tissue inflammation was significantly associated with LUTS, such that there was a 7 point difference in AUA-SI between men with mild vs. severe inflammation (p = 0.004). Additionally, men with a greater waist-hip ratio (WHR) were significantly more likely to have severe prostate tissue inflammation (p = 0.02), and a high WHR was significantly associated with moderate/severe LUTS (OR = 2.56, p = 0.03) among those participants with prostate tissue inflammation. CONCLUSION The WHR, an estimate of centralized obesity, was associated with the severity of inflammatory regions in prostate tissue and with LUTS severity among men with inflammation. Our results suggest centralized obesity advances prostate tissue inflammation to increase LUTS severity. Clinically targeting centralized fat deposition may reduce LUTS severity. Mechanistically, the lack of a clear relationship between systemic inflammatory or oxidative stress markers in blood or urine with prostate size or LUTS suggests pathways other than systemic inflammatory signaling may link body adiposity to BPH outcomes.

Abstract
BACKGROUND To date, the association between obesity and lower urinary tract symptoms (LUTS) is controversial. OBJECTIVE To overcome the current inconsistent results regarding the association between obesity and LUTS and to investigate the association between obesity and LUTS using propensity score matching analysis. SETTING Bariatric center of excellence and health promotion center at university hospital. METHODS From August 2012 to December 2014, a total of 260 obese patients (77 men and 180 women) visited to our bariatric center to undergo bariatric surgery. Patients' International Prostate Symptom Score (IPSS) and overactive bladder symptom score were compared with those of 844 healthy controls who had visited our health center during the same period. To control for the effects of age, 1:1 propensity score matching was used. RESULTS After matching propensity score forage, 73 male patients and 176 female patients were included in our study. In men, all IPSS items except "frequency" were significantly different between obese patients and controls; median scores were higher in the obese group. In women, all IPSS items except "feeling of incomplete emptying" were significantly different between the 2 groups. Both voiding and storage subscores also had marked differences in both genders (P<.001). Total IPSS, quality of life, and total overactive bladder symptom score were significantly different in both genders (P< .001). CONCLUSION There were marked differences in LUTS between obese and nonobese patients, including in voiding and storage symptoms. Considering the relatively young age of both groups, this case-control study supports the hypothesis of a relationship between obesity and bladder pathophysiology.

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
OBJECTIVES To investigate the impact of metabolic components and body composition indices on prostate volume (PV) in a population of middle-aged men receiving health check-ups. METHODS Six hundred and sixteen men receiving health assessments were stratified to large and small prostates based on the cut-off of median PV. Their demographic data, health history, and international prostate symptoms scores (IPSS) were collected. Metabolic components and body composition indices were compared between subjects with large and small prostates. Moreover, the correlations between these parameters and PV were analyzed by multivariate logistic regression. RESULTS The median PV was 27 mL and mean age was 54.8 years. Subjects with large PV were older (56.5 vs. 52.7 years) and had higher serum prostate specific antigen (PSA) level (1.73 vs. 0.96 ng/mL), higher IPSS score (8.37 vs. 6.16), and higher body fat, body mass, and waist circumference (all p<0.05). In multivariate analysis, age (OR, 2.45; 95%CI, 1.74-3.45), serum PSA (OR, 2.75; 95%CI, 1.96-3.86), waist circumference (OR, 1.45; 95%CI, 1.02-2.07), fatness (OR, 1.47; 95%CI, 1.04-2.09), and body fat mass (OR, 1.43; 95%CI, 1.00-2.03) were significantly correlated with PV of study subjects. In subgroup analysis, raised waist circumference (OR, 1.89; 95%CI, 1.00-3.59) was the independent predictor of PV in subjects with bothersome lower urinary tract symptoms. CONCLUSIONS Several metabolic components and body composition indices are significantly associated with PV of middle-aged men, including raised waist circumference, fatness, and body fat mass. Raised waist circumference is the only independent predictor of PV in middle-aged men with bothersome LUTS.

Abstract
BACKGROUND It has been suggested that individuals with metabolic syndrome (MetS) may be prone to developing benign prostatic hyperplasia (BPH), but the direction of causality remains uncertain. The objective of this cross-sectional study was to evaluate the association between BPH and MetS in men who were referred to surgery for BPH. We were interested in identifying the anthropometric, metabolic, and hormonal factors that potentially influence the risk of both conditions. METHODS The study was conducted on 128 males with BPH and 141 without BPH (the control group). Fasting glucose, insulin, lipid profiles, total and free testosterone, estradiol, sex-hormone binding protein (SHBG), dehydroepiandrosterone sulfate (DHEA-S), homeostasis model assessment (HOMA-IR) index, and lipid accumulation product (LAP) were all evaluated. RESULTS The prevalence of MetS was higher in patients with BPH than in the controls (58 vs. 41 %; P = 0.007). In comparison to the controls, patients with BPH had higher levels of cholesterol, low density lipoproteins, DHEA-S, insulin, and HOMA-IR, but lower levels of high-density lipoproteins (HDL), estradiol, and SHBG. The significant predictors of BPH were MetS (OR = 1.961), age (OR = 0.11), HDL (OR = 0.91), insulin (OR = 1.224), SHBG (OR = 0.98), and estradiol (OR = 0.978). Waist circumference and LAP inversely correlated with total and free testosterone and SHBG. CONCLUSIONS Our study confirmed the frequent coexistence of MetS and BPH. This association seems to be a consequence of the MetS-related metabolic derangements, changes in the sex-hormone milieu, and lowered SHBG levels.
