Abstract
OBJECTIVES Nocturnal polyuria (NP) is one of the causes of nocturia that impairs quality of life. It is necessary to consider that NP is latent when the initial treatment for nocturia is unsatisfactory. Therefore, it is important to establish a treatment for NP based on the pathophysiology. We have previously reported the relationship between NP and fluctuation in blood pressure. The present study aimed to investigate the association between NP and 24-h blood pressure fluctuations in a multicenter prospective study. METHODS This study included male patients with lower urinary tract symptoms. We categorized the patients into the nonnocturnal polyuria (non-NP) group (≤0.33) and the NP group (>0.33) based on the nocturnal polyuria index from the frequency volume chart. We measured the 24-h diurnal blood pressure and compared the two groups. RESULTS Among 90 patients, 46 in the non-NP group and 44 in the NP group were included. There was no significant difference in the systolic and diastolic blood pressure during waking time between the two groups; however, the degree of systolic blood pressure reduction during sleep time in the NP group was significantly less than that in the non-NP group (p = 0.039). In the multivariate analysis, systolic BP during sleep was significantly associated with NP (OR 0.970, p = 0.028). CONCLUSION NP is associated with inadequate nocturnal blood pressure reduction in males, suggesting that reduction in nocturnal blood pressure may lead to improvement in nocturia.

Cureus 2023; 15:e50608. [PMID: 38226079 PMCID: PMC10788596 DOI: 10.7759/cureus.50608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/15/2023] [Indexed: 01/17/2024] Open
Abstract
Introduction Population ageing is expected to be accompanied by an increase in multi-morbidity, i.e. the co-occurrence of multiple chronic conditions simultaneously. Benign prostatic hyperplasia (BPH) is a non-malignant disease prevalent in ageing men. Both BPH and multi-morbidity are known to have a significant impact on quality of life. The objective of this study was to determine the association between BPH and multimorbidity among older adults and the elderly population in India. Methods This is an analytical cross-sectional study involving secondary data from the nationally representative Longitudinal Ageing Study in India (LASI) Wave I 2017-18. Multivariable logistic regression analysis was conducted to study the association between BPH and multimorbidity while accounting for other associated factors. Results Compared to those having no co-morbidities, the odds of having BPH increased with the increasing number of co-morbidities. Those with at least two co-morbidities were twice as likely (aOR=2.19; 95%CI 1.78-2.72), and those with at least four co-morbidities were almost six times as likely (aOR=5.78; 95%CI 2-16.72) to have BPH as compared to those with no co-morbidities. The association was stronger among males >60 years. Conclusion Self-reported benign prostatic hyperplasia was found to be strongly associated with multi-morbidity. The need of the hour is the inclusion of BPH within the framework of a national health programme. Health technology assessment of high-risk screening strategies for BPH may be conducted among patients with multimorbidity. Research into the impact on the quality of life of those affected by both BPH and multimorbidity will help highlight this as a priority problem for decision-makers.

Abstract
BACKGROUND The Consortium Linking Academic and Regulatory Insights on Bisphenol A Toxicity (CLARITY-BPA) was a collaborative research effort to better link academic research with governmental guideline studies. This review explores the secondary goal of CLARITY-BPA: to identify endpoints or technologies from CLARITY-BPA and prior/concurrent literature from these laboratories that may enhance the capacity of rodent toxicity studies to detect endocrine disrupting chemicals (EDCs). METHODS A systematic literature search was conducted with search terms for BPA and the CLARITY-BPA participants. Relevant studies employed a laboratory rodent model and reported results on 1 of the 10 organs/organ systems evaluated in CLARITY-BPA (brain and behavior, cardiac, immune, mammary gland, ovary, penile function, prostate gland and urethra, testis and epididymis, thyroid hormone and metabolism, and uterus). Study design and findings were summarized, and a risk-of-bias assessment was conducted. RESULTS Several endpoints and methods were identified as potentially helpful to detect effects of EDCs. For example, molecular and quantitative morphological approaches were sensitive in detecting alterations in early postnatal development of the brain, ovary, and mammary glands. Hormone challenge studies mimicking human aging reported increased susceptibility of the prostate to disease following developmental BPA exposure. Statistical analyses for nonmonotonic dose responses, and computational approaches assessing multiple treatment-related outcomes concurrently in linked hormone-sensitive organ systems, reported effects at low BPA doses. CONCLUSIONS This review provided an opportunity to evaluate the unique insights provided by nontraditional assessments in CLARITY-BPA to identify technologies and endpoints to enhance detection of EDCs in future studies.

Comparative effects of finasteride and laser-irradiated silver nanoparticles on testicular function and histology in testosterone induced benign prostatic hyperplasia in rats. Life Sci 2023; 324:121747. [PMID: 37137466 DOI: 10.1016/j.lfs.2023.121747] [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: 12/23/2022] [Revised: 04/19/2023] [Accepted: 04/26/2023] [Indexed: 05/05/2023]
Abstract
AIMS The objective of this study was to compare the effects of finasteride, a medication used to treat benign prostatic hyperplasia (BPH), and laser irradiated silver nanoparticles (AgNPs), a potential candidate for BPH therapy (Sanchez-Salas, 2017; Marghani et al., 2022) [1,2], on the sex hormone profiles, sperm quality, steroidogenesis, testicular oxidative stress, and histomorphology changes in BPH rats. MATERIALS AND METHODS BPH was induced in male Sprague-Dawley (SD) rats via intramuscular (i.m.) injection of 5 mg/kg BW testosterone propionate (TP) for 14 days. Once the BPH model was induced, rats were divided into four groups (n = 6) as follows: the control group; the BPH group; the BPH/Fina group, which received 5 mg/kg BW finasteride by oral gavage daily for 14 days; and the BPH/AgNPs group, which received a daily intraperitoneal (i.p.) injection of 50 mg/kg BW AgNPs, followed by 5 min of exposure to a 532 nm NIR laser in the prostatic area for the constitutive 14 days. KEY FINDINGS On day 14, the BPH rats had a significant increase in prostate specific antigen (PSA), dihydrotestosterone, and prostate weights, while testicular weights and sperm quality were significantly lower than in the control rats. On day 28, laser irradiated AgNps treated BPH rats showed improved sex hormone balance, testicular weights, sperm quality, steroidogenesis, and an ameliorative effect on testicular histopathology compared to finasteride. SIGNIFICANCE Surprisingly, these findings suggest that laser irradiated AgNPs can be used as an alternative therapy to finasteride for the treatment of BPH without causing negative effects on the testes.

Abstract
OBJECTIVES We hypothesized that the use of an interactive 3D digital anatomy model can improve the quality of communication with patients about prostate disease. METHODS A 3D digital anatomy model of the prostate was created from an MRI scan, according to McNeal's zonal anatomy classification. During urological consultation, the physician presented the digital model on a computer and used it to explain the disease and available management options. The experience of patients and physicians was recorded in questionnaires. RESULTS The main findings were as follows: 308 patients and 47 physicians participated in the study. In the patient group, 96.8% reported an improved level of understanding of prostate disease and 90.6% reported an improved ability to ask questions during consultation. Among the physicians, 91.5% reported improved communication skills and 100% reported an improved ability to obtain patient consent for subsequent treatment. At the same time, 76.6% of physicians noted that using the computer model lengthened the consultation. CONCLUSION This exploratory study found that the use of a 3D digital anatomy model in urology consultations was received overwhelmingly favorably by both patients and physicians, and it was perceived to improve the quality of communication between patient and physician. A randomized study is needed to confirm the preliminary findings and further quantify the improvements in the quality of patient-physician communication.

Abstract
Due to late onset hypogonadism (LOH), there is an increased usage of testosterone replacement therapy (TRT) in the aging male population. Since prostate is a target organ for androgens and anti-androgenic strategies are used to treat and palliate benign prostate hyperplasia (BPH) and prostate cancer (PC), the prevalence of both increases with age, the possible influence of TRT on prostate health becomes highly relevant. The present review summarizes existing data on the associations between endogenous hormone concentrations and prostate growth and concludes that circulating concentrations of androgens do not appear to be associated with the risks of development of BPH or initiation or progression of PC. The explanation for these findings relates to an apparent insensitivity of prostatic tissue to changes of testosterone concentrations within the physiological range.

The global, regional, and national burden of benign prostatic hyperplasia in 204 countries and territories from 2000 to 2019: a systematic analysis for the Global Burden of Disease Study 2019. THE LANCET. HEALTHY LONGEVITY 2022; 3:e754-e776. [PMID: 36273485 PMCID: PMC9640930 DOI: 10.1016/s2666-7568(22)00213-6] [Citation(s) in RCA: 39] [Impact Index Per Article: 19.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 08/31/2022] [Accepted: 09/02/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Benign prostatic hyperplasia is a common urological disease affecting older men worldwide, but comprehensive data about the global, regional, and national burden of benign prostatic hyperplasia and its trends over time are scarce. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we estimated global trends in, and prevalence of, benign prostatic hyperplasia and disability-adjusted life-years (DALYs) due to benign prostatic hyperplasia, in 21 regions and 204 countries and territories from 2000 to 2019. METHODS This study was conducted with GBD 2019 analytical and modelling strategies. Primary prevalence data came from claims from three countries and from hospital inpatient encounters from 45 locations. A Bayesian meta-regression modelling tool, DisMod-MR version 2.1, was used to estimate the age-specific, location-specific, and year-specific prevalence of benign prostatic hyperplasia. Age-standardised prevalence was calculated by the direct method using the GBD reference population. Years lived with disability (YLDs) due to benign prostatic hyperplasia were estimated by multiplying the disability weight by the symptomatic proportion of the prevalence of benign prostatic hyperplasia. Because we did not estimate years of life lost associated with benign prostatic hyperplasia, disability-adjusted life-years (DALYs) equalled YLDs. The final estimates were compared across Socio-demographic Index (SDI) quintiles. The 95% uncertainty intervals (UIs) were estimated as the 25th and 975th of 1000 ordered draws from a bootstrap distribution. FINDINGS Globally, there were 94·0 million (95% UI 73·2 to 118) prevalent cases of benign prostatic hyperplasia in 2019, compared with 51·1 million (43·1 to 69·3) cases in 2000. The age-standardised prevalence of benign prostatic hyperplasia was 2480 (1940 to 3090) per 100 000 people. Although the global number of prevalent cases increased by 70·5% (68·6 to 72·7) between 2000 and 2019, the global age-standardised prevalence remained stable (-0·770% [-1·56 to 0·0912]). The age-standardised prevalence in 2019 ranged from 6480 (5130 to 8080) per 100 000 in eastern Europe to 987 (732 to 1320) per 100 000 in north Africa and the Middle East. All five SDI quintiles observed an increase in the absolute DALY burden between 2000 and 2019. The most rapid increases in the absolute DALY burden were seen in the middle SDI quintile (94·7% [91·8 to 97·6]), the low-middle SDI quintile (77·3% [74·1 to 81·2]), and the low SDI quintile (77·7% [72·9 to 83·2]). Between 2000 and 2019, age-standardised DALY rates changed less, but the three lower SDI quintiles (low, low-middle, and middle) saw small increases, and the two higher SDI quintiles (high and high-middle SDI) saw small decreases. INTERPRETATION The absolute burden of benign prostatic hyperplasia is rising at an alarming rate in most of the world, particularly in low-income and middle-income countries that are currently undergoing rapid demographic and epidemiological changes. As more people are living longer worldwide, the absolute burden of benign prostatic hyperplasia is expected to continue to rise in the coming years, highlighting the importance of monitoring and planning for future health system strain.

Abstract
BACKGROUND Obesity (waist circumference, body mass index (BMI)) and lifestyle factors (dietary habits, smoking, alcohol drinking, Sedentary behavior) have been associated with risk of benign prostatic hyperplasia (BPH) in observational studies, but whether these associations are causal is unclear. METHODS We performed a univariable and multivariable Mendelian randomization study to evaluate these associations. Genetic instruments associated with exposures at the genome-wide significance level (P < 5 × 10-8) were selected from corresponding genome-wide associations studies (n = 216,590 to 1,232,091 individuals). Summary-level data for BPH were obtained from the UK Biobank (14,126 cases and 169,762 non-cases) and FinnGen consortium (13,118 cases and 72,799 non-cases). Results from UK Biobank and FinnGen consortium were combined using fixed-effect meta-analysis. RESULTS The combined odds ratios (ORs) of BPH were 1.24 (95% confidence interval (CI), 1.07-1.43, P = 0.0045), 1.08 (95% CI 1.01-1.17, P = 0.0175), 0.94 (95% CI 0.67-1.30, P = 0.6891), 1.29 (95% CI 0.88-1.89, P = 0.1922), 1.23 (95% CI 0.85-1.78, P = 0.2623), and 1.04 (95% CI 0.76-1.42, P = 0.8165) for one standard deviation (SD) increase in waist circumference, BMI, and relative carbohydrate, fat, protein and sugar intake, 1.05 (95% CI 0.92-1.20, P = 0.4581) for one SD increase in prevalence of smoking initiation, 1.10 (95% CI 0.96-1.26, P = 0.1725) and 0.84 (95% CI 0.69-1.02, P = 0.0741) for one SD increase of log-transformed smoking per day and drinks per week, and 1.31 (95% CI 1.08-1.58, P = 0.0051) for one SD increase in sedentary behavior. Genetically predicted waist circumference (OR = 1.26, 95% CI 1.11-1.43, P = 0.0004) and sedentary behavior (OR = 1.14, 95% CI 1.05-1.23, P = 0.0021) were associated with BPH after the adjustment of BMI. CONCLUSION This study supports independent causal roles of high waist circumference, BMI and sedentary behavior in BPH.

Abstract
Lower urinary tract symptoms (LUTS) commonly affecting ageing men and is thought to be linked with other comorbidities and unhealthy lifestyles. This study was performed to report the prevalence of LUTS and its association with quality of life (QOL) in urination and other related factors. The study was part of the National Health and Morbidity Survey (NHMS) 2019, a cross-sectional community-based survey in Malaysia. Validated self-administered bilingual International Prostate Symptom Score (IPSS) was used to assess the LUTS. Other comorbidities and unhealthy lifestyles were recorded using face-to-face interview and in-situ measurements such as anthropometry assessment and blood measurement. There were a total of 2251 respondents. 16.3% of the respondents had clinically significant LUTS (IPSS ≥ 8). LUTS was found to be significantly associated with QOL, age and inactive physical activities. Nocturia was the most prevalent and bothersome symptom. LUTS is a common condition and adversely affect QOL. Ageing and physically inactive males are associated with the development of LUTS. It is recommended to increase public awareness of the condition and availability of treatment options for LUTS. Any upcoming survey should have a more in-depth investigation such as clinical profiling of subjects.

Abstract
OBJECTIVES Obesity and metabolic status are both modifiable risk factors of lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH). However, the association between metabolically healthy obesity (MHO) and LUTS/BPH is largely unexplored. This study aimed to investigate the risk of LUTS/BPH among different metabolic syndrome-body mass index (MetS-BMI) phenotypes in a cohort of Chinese males. METHODS A total of 3321 males from the China Health and Retirement Longitudinal Study (CHARLS) without history of LUTS/BPH at baseline were included into the analyses. Participants were categorized into six mutually exclusive groups according to presence or absence of MetS combined with BMI status: metabolically healthy normal weight/overweight/obesity (MHN/MHOW/MHO) and metabolically unhealthy normal weight/overweight/obesity (MUN/MUOW/MUO). Adjusted odds ratios (OR) and 95% CI of LUTS/BPH across MetS-BMI categories were estimated with multivariable logistic regression models. RESULTS A total of 394 (11.86%) participants developed LUTS/BPH during the follow-up. After adjusting for age, educational level, smoking status, drinking status, and BMI change, the multivariable-adjusted OR (95% CI) for incident LUTS/BPH comparing MUO, MHO, MUOW, MHOW, and MUN with MHN were 1.99 (1.23-3.22), 2.04 (1.14-3.66), 1.61 (1.11-2.34), 1.45 (1.02-2.05), and 0.91 (0.54-1.56), respectively. CONCLUSIONS MHO and MHOW were risk populations of LUTS/BPH, suggesting that overweight and obesity can independently contribute to LUTS/BPH, even among metabolically healthy individuals. These findings emphasize metabolically healthy individuals may still benefit from maintaining normal body weight to prevent LUTS/BPH. Our findings also support that those recommendations for LUTS/BPH should highlight the importance of maintaining metabolic health across all BMI groups among Chinese males.

Abstract
The concept of bladder ischemia as a contributing factor to detrusor overactivity and lower urinary tract symptoms (LUTS) is evolving. Bladder ischemia as a consequence of pelvic arterial atherosclerosis was first documented in experimental models and later in elderly patients with LUTS. It was shown that early-stage moderate ischemia produces detrusor overactivity, while prolonged severe ischemia provokes changes consistent with detrusor underactivity. Recent studies imply a central role of cellular energy sensors, cellular stress sensors, and stress response molecules in bladder responses to ischemia. The cellular energy sensor adenosine monophosphate-activated protein kinase was shown to play a role in detrusor overactivity and neurodegeneration in bladder ischemia. The cellular stress sensors apoptosis signal-regulating kinase 1 and caspase-3 along with heat shock proteins were characterized as important contributing factors to smooth muscle structural modifications and apoptotic responses in bladder ischemia. Downstream pathways seem to involve hypoxia-inducible factor, transforming growth factor beta, vascular endothelial growth factor, and nerve growth factor. Molecular responses to bladder ischemia were associated with differential protein expression, the accumulation of non-coded amino acids, and post-translational modifications of contractile proteins and stress response molecules. Further insight into cellular stress responses in bladder ischemia may provide novel diagnostic and therapeutic targets against LUTS.

Abstract
BACKGROUND Existing evidence suggests that there is an association between body size and prevalent Benign Prostatic Hyperplasia (BPH)-related outcomes and nocturia. However, there is limited evidence on the association between body size throughout the life-course and incident BPH-related outcomes. METHODS Our study population consisted of men without histories of prostate cancer, BPH-related outcomes, or nocturia in the intervention arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) (n = 4710). Associations for body size in early- (age 20), mid- (age 50) and late-life (age ≥ 55, mean age 60.7 years) and weight change with incident BPH-related outcomes (including self-reported nocturia and physician diagnosis of BPH, digital rectal examination-estimated prostate volume ≥ 30 cc, and prostate-specific antigen [PSA] concentration > 1.4 ng/mL) were examined using Poisson regression with robust variance estimation. RESULTS Men who were obese in late-life were 25% more likely to report nocturia (Relative Risk (RR): 1.25, 95% Confidence Interval (CI): 1.11-1.40; p-trendfor continuous BMI < 0.0001) and men who were either overweight or obese in late-life were more likely to report a prostate volume ≥ 30 cc (RRoverweight: 1.13, 95% CI 1.07-1.21; RRobese: 1.10, 95% CI 1.02-1.19; p-trendfor continuous BMI = 0.017) as compared to normal weight men. Obesity at ages 20 and 50 was similarly associated with both nocturia and prostate volume ≥ 30 cc. Considering trajectories of body size, men who were normal weight at age 20 and became overweight or obese by later-life had increased risks of nocturia (RRnormal to overweight: 1.09, 95% CI 0.98-1.22; RRnormal to obese: 1.28, 95% CI 1.10-1.47) and a prostate volume ≥ 30 cc (RRnormal to overweight: 1.12, 95% CI 1.05-1.20). Too few men were obese early in life to examine the independent effect of early-life body size. Later-life body size modified the association between physical activity and nocturia. CONCLUSIONS We found that later-life body size, independent of early-life body size, was associated with adverse BPH outcomes, suggesting that interventions to reduce body size even late in life can potentially reduce the burden of BPH-related outcomes and nocturia.

Photoselective Vaporization of the Prostate in the Management of Lower Urinary Tract Symptoms in Prostate Cancer Patients on Active Surveillance. Urology 2021; 156:225-230. [PMID: 33539897 DOI: 10.1016/j.urology.2021.01.040] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 01/20/2021] [Accepted: 01/21/2021] [Indexed: 10/22/2022]
Abstract
OBJECTIVE To demonstrate the safety and efficacy of photoselective vaporization of the prostate in alleviating refractory lower urinary tract symptoms in prostate cancer patients who are managed with active surveillance and to explore the association of this procedure with prostate specific antigen (PSA) levels and cancer progression rates. METHODS Between 2008-2018, active surveillance patients who had refractory symptoms and needed surgery were studied. Perioperative functional variables were collected and analyzed. Disease progression was defined as an upgrade or upstage on surveillance biopsies or multiparametric prostate magnetic resonance imaging. Mean postop scores were estimated using locally-weighted methods. The risk of progression was reported using Kaplan-Meier's method. RESULTS Seventy-one patients were included in the study. The median age was 68 years and the median surveillance time before surgery was 4 years. At 12 months, there were substantial improvements in the mean International Prostate Symptom Score (18-5.9), maximum flow rate (6.8-14 mL/s), postvoid residual (240-73mL), PSA (8.1-5.2 ng/mL), and prostate volume (85-57mL). At 30-days, only 2 patients with grade-III complications. Late consequences included tissue regrowth in 4 and urethral stricture (requiring a single dilation) in 3 patients. PSA levels decreased by 36% at 12 months postoperatively. With a median follow-up of 3.7 years, 7 men progressed and received radical treatment. At 3 years, the probability of remaining on surveillance was 93% (95% CI 87%- 100%). CONCLUSION Photoselective vaporization of the prostate offers substantial relief of symptoms in active surveillance patients with refractory symptoms, without adverse effects on disease progression rates.

A Method to Isolate Pericytes From the Mouse Urinary Bladder for the Study of Diabetic Bladder Dysfunction. Int Neurourol J 2021; 24:332-340. [PMID: 33401354 PMCID: PMC7788335 DOI: 10.5213/inj.2040172.086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Accepted: 06/10/2020] [Indexed: 11/19/2022] Open
Abstract
Purpose Pericytes surround the endothelial cells in microvessels and play a distinct role in controlling vascular permeability and maturation. The loss of pericyte function is known to be associated with diabetic retinopathy and erectile dysfunction. This study aimed to establish a technique for the isolation of pericytes from the mouse urinary bladder and an in vitro model that mimics in vivo diabetic bladder dysfunction. Methods To avoid contamination with epithelial cells, the urothelial layer was meticulously removed from the underlying submucosa and detrusor muscle layer. The tissues were cut into multiple pieces, and the fragmented tissues were settled by gravity into collagen I-coated culture plates. The cells were cultured under normal-glucose (5 mmol/L) or high-glucose (30 mmol/L) conditions, and tube formation, cell proliferation, and TUNEL assays were performed. We also performed hydroethidine staining to measure superoxide anion production. Results We successfully isolated high-purity pericytes from the mouse urinary bladder. The cells were positively stained for platelet-derived growth factor receptor-β and NG2 and negatively stained for smooth muscle cell markers (desmin and myosin) and an endothelial cell marker (CD31). The number of tubes formed and the number of proliferating cells were significantly lower when the pericytes were exposed to high-glucose conditions compared with normal-glucose conditions. In addition, there were significant increases in superoxide anion production and the number of apoptotic cells when the pericytes were cultured under high-glucose conditions. Conclusions To the best of our knowledge, this is the first study to isolate and culture pericytes from the mouse urinary bladder. Our model would be a useful tool for screening the efficacy of therapeutic candidates targeting pericyte function in diabetic bladder dysfunction and exploring the functional role of specific targets at the cellular level.

Abstract
Background Tamsulosin is an inhibitory factor of alpha-adrenergic receptors that is used for relieving of the clinical symptoms and management of acute urinary retention. Objective The aim of this study was to evaluate the effects of tamsulosin on the endocrine axis and testicular tissue in adult male rats. Materials and Methods In this experimental study, 30 adult male Wistar rats (weighing 250-300 gr) were divided into three groups: 1) control (received distilled water), 2) experimental 1 (received 0.2 mg/kg/day tamsulosin) and 3) experimental 2 (received 0.4 mg/kg/day tamsulosin) through oral gavage for 28 days. Serum hormones level and testicular histopathology were evaluated at the end of the experiment. Results In this study, the testicular weight decreased significantly in the experimental groups compared to the control group. A significant decrease was seen in testicular weight (p = 0.004) and the number of Leydig cells in tamsulosin-treated groups (p = 0.012). Tamsulosin improved the hormone profile in experimental groups. Also, higher dose of tamsulosin significantly changed the number of Leydig, spermatogonia cells, the thickness of germinal layer, and the diameter of the seminiferous tubules. Conclusion Results showed that using tamsulosin, possibly reduces the testosterone concentration through adrenergic axis system and in turn has destructive effects on proliferative activity of germ cells.

Relation of baseline prostate volume to improvement of lower urinary tract symptoms due to tamsulosin monotherapy in benign prostatic hyperplasia: An exploratory, multicenter, prospective study. Urol Ann 2020; 12:271-275. [PMID: 33100754 PMCID: PMC7546079 DOI: 10.4103/ua.ua_91_19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2019] [Accepted: 01/20/2020] [Indexed: 12/03/2022] Open
Abstract
Aims: The aim of the study was to investigate the relation between baseline prostate volume (PV) and the improvement of lower urinary tract symptoms (LUTS) induced by tamsulosin monotherapy after 2-year follow-up in Egyptian benign prostatic hyperplasia (BPH) patients. Settings and Design: This was a prospective comparative multicenter study. Subjects and Methods: Three hundred and eighty-one BPH patients were included in the study from January 2014 to January 2017. The patients were divided according to their PV into two groups. Group A included patients with small-sized prostate (≤40 ml) and Group B included those with PV larger than 40 ml. Full evaluation was done at presentation. The patients are followed up at 6, 12, and 24 months of continued medical treatment with tamsulosin 0.4 mg once daily. Statistical Analysis Used: Data were coded and entered using the Statistical Package for the Social Sciences version 24. Data were summarized using mean and standard deviation in quantitative data. Comparisons between quantitative variables were done using unpaired t-test or the nonparametric Mann–Whitney test. A comparison between paired measurements in the same person was done using paired t-test (Chan, 2003). P < 0.05 was considered as statistically significant. Results: The mean age was 60.1 ± 7.2 years. The mean value of the International Prostate Symptom Score (IPSS) was recorded for the 381 patients at presentation. In Group A, the mean value of IPSS was 20.44 ± 3.18, whereas in Group B, the mean value of IPSS was 21.23 ± 3.5. There was a significant improvement in symptoms (Qmax-IPSS) in both groups, but we found that this improvement was significantly better in Group A (P = 0.017). Conclusions: PV is an important prognostic factor affecting the improvement of the LUTS by α1-blocker monotherapy. Tamsulosin monotherapy may not be enough for large prostate (>40 mg) to maintain adequate symptom relief, and it is better to start with other medical options such as combined therapy or early nonmedical therapy. Starting α1-blocker monotherapy in smaller prostates may be of benefit in symptomatic patients without considering watchful waiting.

Abstract
Objective Benign prostatic hyperplasia (BPH) is one of the most common diseases found among elderly men. Even though multiple risk factors of BPH have been identified in the past, the risk factors which have a direct impact on prostate volume have not been identified. In this study, we aim to determine the most significant contributing risk factors to prostate volume enlargement by analyzing possible associated risk factors previously studied. Methods This is a quantitative study with an analytical observational design, performed using a retrospective cohort approach. Total sampling was performed on 83 patients who underwent transurethral resection of the prostate (TURP) in Sanglah General Hospital from January to February 2019. Bivariate analysis is performed to examine each variable's association with prostate volume followed by a multivariate analysis. All variables were reassessed with path analysis to measure the direct effects, indirect effects, and total effects on prostate volume. Results Bivariate analysis shows that serum testosterone (R=0.208; p=0.059) and prostate-specific antigen (PSA) level (R=0.626; p=0.001) have a significant association with prostate volume. Multivariate analysis shows that serum PSA (B=1.4; p=0.001; 95% confidence interval [95% CI]=1.039–1.770) and testosterone (B=0.024; p=0.005; 95% CI=0.008–0.041) levels are significant among all the analyzed risk factors. There is a significant and strong effect of PSA to prostate volume (c=0.636; p=0.001) whereas testosterone has a significant albeit weak effect to prostate volume (c=0.246; p=0.009) based on the total effect of the path analysis. Conclusion Serum testosterone and PSA levels are significantly associated with prostatic volume increase among BPH patients.

Abstract
Obstructive voiding disorder (OVD) occurs during aging in men and is often, but not always, associated with increased prostate size, due to benign prostatic hyperplasia (BPH), prostatitis, or prostate cancer. Estrogens are known to impact the development of both OVD and prostate diseases, either during early urogenital tract development in fetal–neonatal life or later in adulthood. To examine the potential interaction between developmental and adult estrogen exposure on the adult urogenital tract, male CD-1 mice were perinatally exposed to bisphenol A (BPA), diethylstilbestrol (DES) as a positive control, or vehicle negative control, and in adulthood were treated for 4 months with Silastic capsules containing testosterone and estradiol (T+E2) or empty capsules. Animals exposed to BPA or DES during perinatal development were more likely than negative controls to have urine flow/kidney problems and enlarged bladders, as well as enlarged prostates. OVD in adult T+E2-treated perinatal BPA and DES animals was associated with dorsal prostate hyperplasia and prostatitis. The results demonstrate a relationship between elevated exogenous estrogen levels during urogenital system development and elevated estradiol in adulthood and OVD in male mice. These findings support the two-hit hypothesis for the development of OVD and prostate diseases.

Abstract
OBJECTIVE We conducted experiments to elucidate the impact of ischemic change on benign prostatic hyperplasia (BPH) using immunohistochemistry. METHODS Medical records of consecutive patients over 60 years of age who underwent transurethral resection of the prostate for BPH between January 2009 and September 2012 were evaluated. As vascular risk factors, the presence or absence of diabetes mellitus, hypertension, current smoking, obesity, dyslipidemia, and diseases related to bladder function were investigated. As BPH-related factors, International Prostate Symptom Score, quality of life, maximal flow rate, postvoid residual volume, prostate-specific antigen, prostate volume, prostate calculi, and medication state for BPH were investigated. Immunohistochemistry was performed for hypoxia-inducible factor (HIF-1α), sex hormone receptors, and smooth muscle actin. Additionally, microvessel density (MVD) and diffuse fibrosis (DF) were evaluated. RESULTS A total of 101 patients were included and HIF-1α expression in stroma and glands were observed in 56 (55.4%) and 34 (33.7%) cases, respectively. There was no significant association between HIF-1α expression and vascular risk factors or BPH-related variables. However, there was a significant correlation between the HIF-1α expression in stroma and higher MVD. HIF-1α expression in the stroma was also significantly correlated with higher expressions of the androgen and progesterone receptors in the stroma. DF was frequently found in cases with higher HIF-1α expression in the stroma than in those with lower HIF-1α expression. CONCLUSION In patients with response to ischemic changes of the prostate, HIF-1α expression could be confirmed, and the expression of the androgen receptor was significantly lower in these patients. Chronic ischemic damage in the prostate can progress to a condition that is refractory to pharmacologic therapy. Chronic ischemic damage, which can progress to refractory phase to pharmacologic therapy, is correlated with the hormonal status of prostate.

Abstract
OBJECTIVE To evaluate the global prevalence of erectile dysfunction (ED); as well as its association with physiological and pathological ageing by examining the relationship between ED and cardiovascular disease (CVD), benign prostatic hyperplasia (BPH), and dementia. We also aimed to characterise discrepancies caused by the use of different ED screening tools. METHODS The Excerpta Medica dataBASE (EMBASE) and Medical Literature Analysis and Retrieval System Online (MEDLINE) were searched to find population-based studies investigating the prevalence of ED and the association between ED and CVD, BPH, and dementia in the general population. RESULTS The global prevalence of ED was 3-76.5%. ED was associated with increasing age. Use of the International Index of Erectile Function (IIEF) and Massachusetts Male Aging Study (MMAS)-derived questionnaire identified a high prevalence of ED in young men. ED was positively associated with CVD. Men with ED have an increased risk of all-cause mortality odds ratio (OR) 1.26 (95% confidence interval [CI] 1.01-1.57), as well as CVD mortality OR 1.43 (95% CI 1.00-2.05). Men with ED are 1.33-6.24-times more likely to have BPH then men without ED, and 1.68-times more likely to develop dementia than men without ED. CONCLUSION ED screening tools in population-based studies are a major source of discrepancy. Non-validated questionnaires may be less sensitive than the IIEF and MMAS-derived questionnaire. ED constitutes a large burden on society given its high prevalence and impact on quality of life, and is also a risk factor for CVD, dementia, and all-cause mortality.

The Distribution of Post-Void Residual Volumes in People Seeking Care in the Symptoms of Lower Urinary Tract Dysfunction Network Observational Cohort Study With Comparison to Asymptomatic Populations. Urology 2019; 130:22-28. [PMID: 31018115 PMCID: PMC6660395 DOI: 10.1016/j.urology.2019.01.069] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Revised: 01/16/2019] [Accepted: 01/30/2019] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To describe the distribution of post-void residual (PVR) volumes across patients with and without lower urinary tract symptoms (LUTS) and examine relationships between self-reported voiding symptoms, storage symptoms, and PVR. METHODS PVR and demographic data were obtained from the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) observational cohort study. Self-reported symptoms were collected using the American Urological Association Symptom Index and the LUTS Tool. PVR values were obtained from 2 other cohorts: living kidney donors with unknown LUTS from the Renal and Lung Living Donors Evaluation Study (RELIVE), and continent women in the Establishing the Prevalence of Incontinence (EPI) study, a population-based study of racial differences in urinary incontinence prevalence. RESULTS Across the 3 studies, median PVRs were similar: 26 mL in LURN (n = 880, range 0-932 mL), 20 mL in EPI (n = 166, range 0-400 mL), and 14 mL in RELIVE (n = 191, range 0-352 mL). In LURN, males had 3.6 times higher odds of having PVR > 200 mL (95% CI = 1.72-7.48). In RELIVE, median PVR was significantly higher for males (20 mL vs 0 mL, P= .004). Among women, only the intermittency severity rating was associated with a probability of an elevated PVR. Among men, incomplete emptying and burning severity rating were associated with a higher odds of elevated PVR, but urgency severity ratings were associated with lower odds of elevated PVR. CONCLUSION Care-seeking patients have PVRs similar to those in people with unknown history of LUTS (RELIVE) and without self-reported LUTS (EPI). Although PVR was correlated with voiding symptoms, the mean differences only explain ∼2% of the variance.

Abstract
INTRODUCTION In the development of terminology of the lower urinary tract, due to its increasing complexity, the terminology for male lower urinary tract and pelvic floor symptoms and dysfunction needs to be updated using a male-specific approach and via a clinically-based consensus report. METHODS This report combines the input of members of the Standardisation Committee of the International Continence Society (ICS) in a Working Group with recognized experts in the field, assisted by many external referees. Appropriate core clinical categories and a subclassification were developed to give a numeric coding to each definition. An extensive process of 22 rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). RESULTS A Terminology Report for male lower urinary tract and pelvic floor symptoms and dysfunction, encompassing around 390 separate definitions/descriptors, has been developed. It is clinically-based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in male lower urinary tract and pelvic floor dysfunction. Male-specific imaging (ultrasound, radiology, CT, and MRI) has been a major addition whilst appropriate figures have been included to supplement and help clarify the text. CONCLUSIONS A consensus-based Terminology Report for male lower urinary tract and pelvic floor symptoms and dysfunction has been produced aimed at being a significant aid to clinical practice and a stimulus for research.

Abstract
Objective: To discover the correlation of clinical and physiological measures for benign prostatic hyperplasia in hypertensive and normotensive patients. Methods: From September 2016 to October 2017, 435 patients were enrolled for further selection. The parameters evaluated for eligible patients included prostate volume, systolic blood pressure, diastolic blood pressure, international prostate symptom score, etc. Then the eligible patients were divided into two groups according to hypertension condition, and the clinical and physiological parameters were compared between two groups. The Pearson’s correlation coefficient was used to test the linearity of the relationships of these clinical and physiological components with prostate volume, total prostate specific antigen, and international prostate symptom score. Results: Finally, 350 patients were involved in this study, including 117 with hypertension and 233 without hypertension. Weight, body mass index, systolic blood pressure, and diastolic blood pressure were significantly different between the hypertension and normotension groups. In the normotension group, there were positive correlations between weight, body mass index, age, and prostate volume; between fasting blood sugar, systolic blood pressure, diastolic blood pressure, and total prostate specific antigen; between fasting blood sugar and international prostate symptom score. In the hypertension group, there were positive correlations between age and total prostate specific antigen and international prostate symptom score; between weight and prostate volume; between systolic blood pressure and total prostate specific antigen. Conclusion: This study indicated that there might be no significant association between hypertension and prostate volume.

PSA predicts development of incident lower urinary tract symptoms: results from the REDUCE study. Prostate Cancer Prostatic Dis 2018; 21:238-244. [PMID: 29795141 DOI: 10.1038/s41391-018-0044-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2017] [Revised: 02/06/2018] [Accepted: 02/17/2018] [Indexed: 11/09/2022]
Abstract
BACKGROUND The relationship between baseline prostate-specific antigen (PSA) and development of lower urinary tract symptoms (LUTS) in asymptomatic and mildly symptomatic men is unclear. We sought to determine if PSA predicts incident LUTS in these men. METHODS A post-hoc analysis of the 4-year REDUCE study was performed to assess for incident LUTS in 1534 men with mild to no LUTS at baseline. The primary aim was to determine whether PSA independently predicted incident LUTS after adjusting for the key clinical variables of age, prostate size, and baseline International prostate symptom score (IPSS). Incident LUTS was defined as the first report of medical treatment, surgery, or sustained clinically significant symptoms (two IPSS >14). Cox proportional hazards, cumulative incidence curves, and the log-rank test were used to test our hypothesis. RESULTS A total of 1534 men with baseline IPSS <8 were included in the study cohort. At baseline, there were 335 men with PSA 2.5-4 ng/mL, 589 with PSA 4.1-6 ng/mL, and 610 with PSA 6-10 ng/mL. During the 4-year study, 196 men progressed to incident LUTS (50.5% medical treatment, 9% surgery, and 40.5% new symptoms). As a continuous variable, higher PSA was associated with increased incident LUTS on univariable (HR 1.09, p = 0.019) and multivariable (HR 1.08, p = 0.040) analysis. Likewise, baseline PSA 6-10 ng/mL was associated with increased incident LUTS vs. PSA 2.5-4 ng/mL in adjusted models (HR 1.68, p = 0.016). This association was also observed in men with PSA 4.1-6 ng/mL vs. PSA 2.5-4 ng/mL (HR 1.60, p = 0.032). CONCLUSIONS Men with mild to no LUTS but increased baseline PSA are at increased risk of developing incident LUTS presumed due to benign prostatic hyperplasia.

Abstract
Bladder cancer and benign prostatic hyperplasia have been two very common diseases among the elderly men, especially with the aging of the population in the world. We have designed a study to investigate the clinical effect of interventional therapy for plasmakinetic resection of the prostate and plasmakinetic resection of the bladder, which is called "BPSC" (The bladder cancer and benign prostatic hyperplasia study in Chinese population). The BPSC is not only a specific study, it is made up of many studies. In this article, we introduced the research background, source, name, study framework, study management and further direction of BPSC project. We hope this process will contribute to the growth of the database through sharing data and enriching the evidence of bladder cancer and benign prostatic hyperplasia in the Chinese population, thereby finally improving the accessibility of these important findings for doctors, researchers, and patients.

Abstract
Background Numerous medications are known to be associated with the development of lower urinary tract symptoms (LUTS). One such medication group is calcium channel blockers (CCB). Objective To critically examine the literature regarding the involvement of CCB in manifestation of LUTS in humans. Methods A systematic literature search was conducted on PubMed, SciELO, Scopus, and OpenGrey databases to find all potentially relevant research studies before August 2016. Results Five studies met the inclusion criteria and were included in this review. Three out of five studies stated that CCB were involved in either precipitation or exacerbation of LUTS. As for the remaining two studies, one study found out that only the monotherapy of CCB was associated with increased prevalence of nocturia and voiding symptoms in young females, whereas the other study reported an inverse association of CCB with LUTS. The methodological quality of studies was considered high for four studies and low for one study. Conclusion Healthcare providers should make efforts for an earlier identification of the individuals at risk of LUTS prior to the commencement of CCB therapy. Moreover, patients should be counselled to notify their healthcare provider if they notice urinary symptoms after the initiation of CCB.

Abstract
BACKGROUND AND AIM Senile prostatic enlargement due to benign prostatic hyperplasia (BPH) is a common problem among older men, and is responsible for considerable disability. This study was conducted to determine the prevalence and determinants of the clinically diagnosed prostatic enlargement among elderly men in Arar, Northern Saudi Arabia. METHODS This cross-sectional study was carried out on all consented elderly males attending the outpatient clinic of the urology department of Arar Central Hospital from February 2017 to July 30, 2017. Each participant underwent a general examination and digital per rectal to detect general chronic diseases, obesity and prostatic enlargement. Data were analyzed by SPSS version 16, using descriptive statistics and Chi-squared test. RESULTS Among 81 elderly male participants in the study, 19.8% had clinically diagnosed senile prostatic enlargement (SPE) and 3.7% had prostatic tumors. There was significant relation between SPE and age as 6.2% of cases were 60-69 years, 43.8% were 70-79 years and 44.0% were 80 years or more (p<0.05). There was also significant relation between SPE and obesity as 62.5% of cases were obese and 37.5% were non obese (p<0.05). There was no significant relation with marital status, smoking or diabetes mellitus (p<0.05). CONCLUSION Senile prostatic enlargement is one of the significant important issues in public health in Arar city, Northern Saudi Arabia. The prevalence of this condition reaches 19.3%, thereby placing even greater burden on the quality of life of the elderly and on the health system in the region.

Abstract
Clinical benign prostatic hyperplasia (BPH) is one of the most common diseases in ageing men and the most common cause of lower urinary tract symptoms (LUTS). The prevalence of BPH increases after the age of 40 years, with a prevalence of 8%-60% at age 90 years. Some data have suggested that there is decreased risk among the Asians compared to the western white population. Genetics, diet and life style may play a role here. Recent reports suggest the strong relationship of clinical BPH with metabolic syndrome and erectile dysfunction, as well as the possible role of inflammation as a cause of the prostatic hyperplasia. Lifestyle changes including exercise and diet are important strategies in controlling this common ailment.

Abstract
PURPOSE We determined whether decreased peak urine flow is associated with future incident lower urinary tract symptoms in men with mild to no lower urinary tract symptoms. MATERIALS AND METHODS Our population consisted of 3,140 men from the REDUCE (Reduction by Dutasteride of Prostate Cancer Events) trial with mild to no lower urinary tract symptoms, defined as I-PSS (International Prostate Symptom Score) less than 8. REDUCE was a randomized trial of dutasteride vs placebo for prostate cancer prevention in men with elevated prostate specific antigen and negative biopsy. I-PSS measures were obtained every 6 months throughout the 4-year study. The association between peak urine flow rate and progression to incident lower urinary tract symptoms, defined as the first of medical treatment, surgery or sustained and clinically significant lower urinary tract symptoms, was tested by multivariable Cox models, adjusting for various baseline characteristics and treatment arm. RESULTS On multivariable analysis as a continuous variable, decreased peak urine flow rate was significantly associated with an increased risk of incident lower urinary tract symptoms (p = 0.002). Results were similar in the dutasteride and placebo arms. On univariable analysis when peak flow was categorized as 15 or greater, 10 to 14.9 and less than 10 ml per second, flow rates of 10 to 14.9 and less than 10 ml per second were associated with a significantly increased risk of incident lower urinary tract symptoms (HR 1.39, p = 0.011 and 1.67, p <0.001, respectively). Results were similar on multivariable analysis, although in the 10 to 14.9 ml per second group findings were no longer statistically significant (HR 1.26, p = 0.071). CONCLUSIONS In men with mild to no lower urinary tract symptoms a decreased peak urine flow rate is independently associated with incident lower urinary tract symptoms. If confirmed, these men should be followed closer for incident lower urinary tract symptoms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional medicine has used Uvaria rufa Blume as an ethnomedicinal plant for treating fever, skin allergies, intestinal ulcers and prostate disorders including BPH. However, no scientific evidence supports the traditional use. AIM OF THE STUDY This study aimed to evaluate the therapeutic potential of U. rufa on BPH using in vitro and in vivo models. MATERIALS AND METHODS In vitro studies screened the efficacy of a 5α-reductase (5αR) inhibition and antioxidant activity of petroleum ether, ethyl acetate, ethanol and aqueous extracts from the stem of U. rufa. Phytochemical screening was performed to determine the active compound using high-performance liquid chromatography (HPLC). Ethyl acetate extract (UR-EtOAc) of U. rufa was used to evaluate the therapeutic efficacy in vivo models. BPH was induced by subcutaneous injection of testosterone propionate (3mg/kg) to male rats for 30 days. After 30 days of oral administration of UR-EtOAc at doses of 10 and 20mg/kg and finasteride at a dose of 1mg/kg, the prostate weight, prostate index (PI), testosterone and androgen receptor (AR) levels, and histopathological alteration of prostate gland were determined. Also, oxidative status and toxicity indices were assessed. RESULTS UR-EtOAc exhibited the highest potency of inhibition of 5αR and possessed potent antioxidants rich in phenolics and flavonoids contents. The active compound analyzed by HPLC was β-sitosterol. In vivo results show a significant reduction in prostate weight, PI, and AR in all treated groups when compared to the BPH model group (P<0.001). Also, the UR-EtOAc and finasteride treated groups had increased prostatic and serum testosterone levels when compared to the BPH model group. A histopathological investigation of the prostate glands supported the above results. UR-EtOAc elevated the antioxidant enzymes and reduced the malondialdehyde level in BPH-induced rats. Moreover, treatment of UR-EtOAc at all doses had no toxic effects on the vital organs and serum biochemical indices. CONCLUSIONS UR-EtOAc from the stem of Uvaria rufa Blume appears to have the potential as a phytotherapeutic agent in the management of BPH, which provides the scientific evidence for traditional use.

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
Lower urinary tract symptoms (LUTS) are a group of voiding symptoms affecting both genders as they age. Traditionally, LUTS in men were commonly attributed to bladder outlet obstruction (BOO) due to benign prostatic enlargement (BPE). It was later shown that, in approximately one-third to more than one-half of cases, LUTS in men are not associated with BOO. Urodynamic changes in the male bladder and symptom scores in aging men were found to be identical to their age-matched female counterparts. These observations suggested that LUTS in the elderly do not necessarily relate to BOO and may result from local changes in bladder muscle, nerves, and blood vessels. However, aging factors predisposing to bladder dysfunction and LUTS remain unknown. Growing evidence suggests that aging-associated pelvic ischemia may be a primary factor in the development of nonobstructed nonneurogenic overactive bladder and LUTS. First identified in experimental models and later in clinical studies, pelvic ischemia has been shown to compromise the lower urinary tract structure and lead to dysfunction. Structural and functional consequences of bladder and prostate ischemia have been documented in animal models. Clinical studies have shown that bladder and prostate blood flow decreases with aging. The severity of LUTS in elderly patients correlates with the degrees of bladder ischemia. LUTS improvement with α blockers has been associated with increased bladder blood flow. Pelvic ischemia may be an independent factor in nonobstructed nonneurogenic bladder instability and LUTS. Further research into the pathophysiology of LUTS in pelvic ischemia may lead to better management of this problem in the elderly population.

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 determine the lower urinary tract symptoms (LUTS) profile and factors affecting its degree of severity including cardiovascular risk profile, age, ethnicity, education level and prostate volume in a multiethnic Asian setting. Materials and Methods We conducted a cross-sectional study of 1021 men aged 40–79 years with no clinical evidence of prostate cancer, prostate surgery or 5α-reductase inhibitor treatment of known prostate conditions. The severity of LUTS was assessed using the International Prostate Symptom Score (IPSS). Potential factors associated with LUTS including age, ethnicity, education, history of hypertension, diabetes and hypercholesterolemia, height, weight, and prostate volume were evaluated using univariable and multivariable analyses. Results There were 506 (50%) men found to have moderate-to-severe LUTS attaining an IPSS above 7. Overall, nocturia (45.5%) was the most frequently reported symptom. Multivariable analysis showed that age, ethnicity, prostate volume and history of hypertension and hypercholesterolemia were independent factors associated with severity of LUTS (p < 0.05). Considering individual lower urinary tract symptoms, we found a strong association of storage symptom with history of hypertension and hypercholesterolemia. Malay men were significantly bothered by post micturition symptom compared to their Chinese and Indian counterparts. Stratified analyses of LUTS demonstrated a mutually exclusive cardiovascular risk factors profile defined by ethnicity. Conclusion Severity of LUTS varies between different ethnicities across all age groups. In addition to age and prostate volume, ethnicity and cardiovascular risk factors including hypertension and hypercholesterolemia may also need to be taken into account in managing men with LUTS.

Abstract
Purpose We assessed whether weight reduction is an effective intervention for the management of lower urinary tract symptoms (LUTS) and investigated the relationship between obesity and LUTS. Materials and Methods This was a prospective randomized controlled trial that enrolled obese men older than 50 years with LUTS. The study period was 52 weeks. All patients received standardized alpha-adrenergic blocker therapy for the treatment of benign prostatic hyperplasia (BPH) during the run-in period. Patients were randomized to receive either a standardized prerecorded video program on the general principle of weight reduction or a comprehensive weight reduction program. Patients were assessed at different time points with symptom assessment, uroflowmetry, transrectal ultrasound, and metabolic assessment. Results Sixty-five patients were allocated to each study arm. After the study period, no significant difference in weight reduction was found between the two arms. When the pre- and postintervention parameters were compared, none were statistically different between the 2 arms, namely nocturia, International Prostate Symptom Score, quality of life assessment, and uroflowmetry parameters. When the whole study population was taken as a single cohort, these parameters were also not significantly different between the group with a body mass index of 25 to <30 kg/m2 and the group with a BMI of 30 to 35 kg/m2. Conclusions We found no association between obesity and LUTS. This could have been due to the less marked weight difference in our cohort. Whereas weight reduction may be an effective measure to improve LUTS, the implementation of a successful program remains a challenge.

Abstract
BACKGROUND Knowledge of factors associated with the course of lower urinary tract symptoms (LUTS) before treatment is needed to inform preventive interventions. In a prospective study of elderly men untreated for LUTS, we identified factors associated with symptom progression and remission. METHODS In community-dwelling US men aged ≥65 years, the American Urological Association Symptom Index (AUA-SI) was repeated four times, once at baseline (2000-2002) and then every 2 years thereafter. Analyses included 1740 men with all four AUA-SI assessments, who remained free from diagnosed prostate cancer, and who reported no treatment for LUTS or BPH during follow-up that averaged 6.9 (±0.4) years. LUTS change was determined with group-based trajectory modelingof the repeated AUA-SI measures. Multivariable logistic regression was then used to determine the baseline factors associated with progressing compared with stable trajectories, and with remitting compared with progressing trajectories. Lifestyle, body mass index (BMI) (kg/m(2)), mobility, mental health (Short-Form 12), medical history and prescription medications were considered for selection. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated for variables in each model. RESULTS We identified 10 AUA-SI trajectories: 4 stable (1277 men, 73%), three progressing (345 men, 20%), two remitting (98 men, 6%) and one mixed (20 men, 1%). Men in progressing compared with stable trajectories were more likely to have mobility limitations (OR=2.0, 95% CI: 1.0-3.8), poor mental health (OR=1.9, 95% CI: 1.1-3.4), BMI≥25.0 kg m(-2) (OR=1.7, 95% CI: 1.0-2.8), hypertension (OR=1.5, 95% CI: 1.0-2.4) and back pain (OR=1.5, 95% CI: 1.0-2.4). Men in remitting compared with progressing trajectories more often used central nervous system medications (OR=2.3, 95% CI: 1.1-4.9) and less often had a history of problem drinking (OR=0.4, 95% CI: 0.2-0.9). CONCLUSIONS Several non-urological lifestyle and health factors were independently associated with risk of LUTS progression in older men.

Abstract
OBJECTIVE To better risk stratify patients, using baseline characteristics, to help optimise decision-making for men with moderate-to-severe lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) through a secondary analysis of the Medical Therapy of Prostatic Symptoms (MTOPS) trial. PATIENTS AND METHODS After review of the literature, we identified potential baseline risk factors for BPH progression. Using bivariate tests in a secondary analysis of MTOPS data, we determined which variables retained prognostic significance. We then used these factors in Cox proportional hazard modelling to: i) more comprehensively risk stratify the study population based on pre-treatment parameters and ii) to determine which risk strata stood to benefit most from medical intervention. RESULTS In all, 3047 men were followed in MTOPS for a mean of 4.5 years. We found varying risks of progression across quartiles. Baseline BPH Impact Index score, post-void residual urine volume, serum prostate-specific antigen (PSA) level, age, American Urological Association Symptom Index score, and maximum urinary flow rate were found to significantly correlate with overall BPH progression in multivariable analysis. CONCLUSIONS Using baseline factors permits estimation of individual patient risk for clinical progression and the benefits of medical therapy. A novel clinical decision tool based on these analyses will allow clinicians to weigh patient-specific benefits against possible risks of adverse effects for a given patient.

Abstract
Benign prostatic hyperplasia (BPH) is a histological diagnosis associated with unregulated proliferation of connective tissue, smooth muscle and glandular epithelium. BPH may compress the urethra and result in anatomic bladder outlet obstruction (BOO); BOO may present as lower urinary tract symptoms (LUTS), infections, retention and other adverse events. BPH and BOO have a significant impact on the health of older men and health-care costs. As the world population ages, the incidence and prevalence of BPH and LUTS have increased rapidly. Although non-modifiable risk factors – including age, genetics and geography – play significant roles in the etiology of BPH and BOO, recent data have revealed modifiable risk factors that present new opportunities for treatment and prevention, including sex steroid hormones, the metabolic syndrome and cardiovascular disease, obesity, diabetes, diet, physical activity and inflammation. We review the natural history, definitions and key risk factors of BPH and BOO in epidemiological studies.

Abstract
PURPOSE We prospectively evaluated the association between adiposity and the risk of lower urinary tract symptoms incidence and progression in the Health Professionals Followup Study (HPFS). MATERIALS AND METHODS At baseline participants reported current height and weight, and weight at age 21 years. A year later they reported waist and hip circumferences, and every 2 years thereafter they reported weight. Participants periodically completed the International Prostate Symptom Score (I-PSS) and reported surgery or medication use for lower urinary tract symptoms. We used Cox proportional hazards regression to estimate the multivariable adjusted association between adiposity and lower urinary tract symptoms incidence and progression. The incidence analytical cohort of 18,055 men had no lower urinary tract symptoms at baseline. A total of 6,461 men entered the progression analytical cohort when they first experienced lower urinary tract symptoms. RESULTS The risk of lower urinary tract symptoms in 4,088 cases increased with increasing body mass index (35 kg/m(2) or greater vs 23 to less than 25 HR 1.61, 95% CI 1.31-1.99), waist circumference (greater than 42 inches vs 33 or less HR 1.39, 95% CI 1.19-1.63) and weight gain since age 21 years (50 pounds or greater vs stable weight HR 1.31, 95% CI 1.17-1.46, each p trend <0.0001). The risk of lower urinary tract symptom progression in 1,691 cases increased with body mass index (35 kg/m(2) or greater vs 23 to less than 25 HR 1.44, 95% CI 1.04-2.00, p trend <0.0001), weight gain since age 21 years (50 pounds or greater vs stable weight HR 1.35, 95% CI 1.14-1.60, p trend <0.0001) and waist circumference (greater than 42 inches vs 33 or less HR 1.32, 95% CI 0.95-1.85, p trend 0.005). CONCLUSIONS Men with higher total and abdominal adiposity and those who gained weight were more likely to have lower urinary tract symptoms develop or progress. Our findings support the notion that obesity may be an important target for lower urinary tract symptom prevention and intervention.

Systematic review and meta-analysis of candidate gene association studies of lower urinary tract symptoms in men. Eur Urol 2014; 66:752-68. [PMID: 24491308 PMCID: PMC4410299 DOI: 10.1016/j.eururo.2014.01.007] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2013] [Accepted: 01/10/2014] [Indexed: 12/15/2022]
Abstract
Context Although family studies have shown that male lower urinary tract symptoms (LUTS) are highly heritable, no systematic review exists of genetic polymorphisms tested for association with LUTS. Objective To systematically review and meta-analyze studies assessing candidate polymorphisms/genes tested for an association with LUTS, and to assess the strength, consistency, and potential for bias among pooled associations. Evidence acquisition A systematic search of the PubMed and HuGE databases as well as abstracts of major urologic meetings was performed through to January 2013. Case-control studies reporting genetic associations in men with LUTS were included. Reviewers independently and in duplicate screened titles, abstracts, and full texts to determine eligibility, abstracted data, and assessed the credibility of pooled associations according to the interim Venice criteria. Authors were contacted for clarifications if needed. Meta-analyses were performed for variants assessed in more than two studies. Evidence synthesis We identified 74 eligible studies containing data on 70 different genes. A total of 35 meta-analyses were performed with statistical significance in five (ACE, ELAC2, GSTM1, TERT, and VDR). The heterogeneity was high in three of these meta-analyses. The rs731236 variant of the vitamin D receptor had a protective effect for LUTS (odds ratio: 0.64; 95% confidence interval, 0.49–0.83) with moderate heterogeneity (I2 = 27.2%). No evidence for publication bias was identified. Limitations include wide-ranging phenotype definitions for LUTS and limited power in most meta-analyses to detect smaller effect sizes. Conclusions Few putative genetic risk variants have been reliably replicated across populations. We found consistent evidence of a reduced risk of LUTS associated with the common rs731236 variant of the vitamin D receptor gene in our meta-analyses. Patient summary Combining the results from all previous studies of genetic variants that may cause urinary symptoms in men, we found significant variants in five genes. Only one, a variant of the vitamin D receptor, was consistently protective across different populations.

Abstract
Nocturia is a risk factor for morbidity and mortality but is frequently overlooked and underreported by patients and unrecognized by physicians. Epidemiologic studies reported that nocturnal voiding is associated not only with aging and benign prostatic hyperplasia, but also with many other clinical conditions. The majority of epidemiologic studies reported a significant relationship between nocturia and hypertension. However, the cause-and-effect relationship between them has not been established. Some physiopathological changes in hypertension are conducive to result in nocturia. These include the effects of hypertension on glomerular filtration and tubular transport, resetting of the kidney pressure-natriuresis relationship, atrial stretch and release of atrial natriuretic peptide when congestive heart failure complicates hypertension, and peripheral edema. Another link between hypertension and nocturia is obstructive sleep apnea. Furthermore, some evidence supports the relationship between nondipping behavior of blood pressure and an increased prevalence of nocturia. The use of some classes of antihypertensive agents may result in nocturia. The present review aims to provide a comprehensive evaluation of the epidemiologic evidence and physiopathological links that correlate hypertension and nocturia. Emphasis is placed on the need to take a pro-active attitude to detect and treat this hazardous condition.

Abstract
PURPOSE We determined the metabolic, lifestyle and physical factors associated with progression or improvement of storage and voiding lower urinary tract symptoms in a population based cohort of men. MATERIALS AND METHODS After the exclusion of men with prostate or bladder cancer and/or surgery from the study, progression and improvement of storage and voiding lower urinary tract symptoms was assessed using the AUA-SI (American Urological Association symptom index) in 780 men, age 35 to 80 years at baseline, who attended 5-year followup clinics. RESULTS Storage and voiding lower urinary tract symptoms progressed in 39.8% (308) and 32.3% (250) of men, and improved in 33.1% (256) and 23.4% (181), respectively. In final adjusted regression models greater bother and physical activity at baseline predicted improvement in storage and voiding lower urinary tract symptoms, while greater income, high-density lipoprotein cholesterol and lower triglycerides predicted improvement of storage lower urinary tract symptoms only. Being widowed, higher plasma estradiol and depression at baseline predicted the progression of storage and voiding lower urinary tract symptoms, while greater abdominal fat mass and obstructive sleep apnea risk predicted the progression of storage lower urinary tract symptoms only. Older age, lower high-density lipoprotein cholesterol, testosterone, income, previous benign prostatic hyperplasia and erectile dysfunction at baseline predicted the progression of voiding lower urinary tract symptoms only. The initiation or continued use of α-blockers or anticholinergics (storage lower urinary tract symptoms), and 5α-reductase inhibitors (voiding lower urinary tract symptoms), were associated with symptom improvement. CONCLUSIONS Lower urinary tract symptoms may progress or remit. Even accounting for medication use, progression may be associated with modifiable disease, or metabolic or behavioral factors, which are also risk factors for type 2 diabetes and cardiovascular disease. These factors should be looked for and managed.
