Project description:The first clinical guidelines for male lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) were published in 2005. An update is urgently needed in view of BPH being recognised as one of ten chronic illnesses by the Ministry of Health, Singapore. This review summarises the definition of BPH and the epidemiology of male LUTS/BPH in Singapore. BPH can be phenotyped with noninvasive transabdominal ultrasonography, according to intravesical prostatic protrusion and prostate volume, and classified according to severity (staging) for individualised treatment. At the initial evaluation, the majority of patients (59%) can be managed with fluid adjustment, exercise and diet; 32% with medications, using alpha blockers and/or 5-alpha reductase inhibitors for prostates weighing more than 30 g; and 9% with surgical intervention for more advanced disease. The 2015 guidelines comprise updated evidence that will help family medicine practitioners and specialists manage this common ailment more cost-effectively.
Project description:This study investigated trends in the prescription of ?-blockers for patients with BPH, focusing on changing patterns of prescriptions during 2002-2013 using National Health Insurance Service-National Sample Cohort data. A total of 65,596 Korean males over 50 years old diagnosed with BPH were identified from the NHIS-NSC database between 2002-2013. Patterns of each ? -blocker prescription were analyzed and persistence rate, switch rate, and return rate during a follow-up period of 3 years after the first prescription were calculated. A total of 28,318 men over 50 years old (64.95?±?9.12), changed medication within six months following the first prescription of ? -blocker. (1) Tamsulosin showed the highest persistence rate when compared with other ?-blockers (2) Among patients who switched to a second ?-blocker, tamsulosin showed the highest return rate when compared with other ?-blockers. Tamsulosin has been the most commonly prescribed ?1-blocker since the mid-2000s, in line with its demonstrated highest persistence and return rates. These data probably reflect patient satisfaction with ?1-blockers in the management of BPH, in which the decision to stop and switch pharmacological treatments is primarily based on changes in symptoms or side effects.
Project description:To examine trends in medical management of men with benign prostatic hyperplasia/lower urinary tract symptoms (BPH/LUTS) in relation to sentinel events specific to particular medication regimens.Using the National Ambulatory Medical Care Survey (1993-2010), we identified outpatient visits by men with BPH/LUTS. We ascertained prescriptions for medical therapy and distinguished between treatment with alpha-blocker monotherapy, 5? reductase inhibitor monotherapy, combination therapy, and anticholinergic therapy. We evaluated temporal trends in prescription patterns and assessed for changes after sentinel events related to each regimen (eg, Food and Drug Administration [FDA] approval for tamsulosin and alpha-blocker monotherapy). Finally, we used multivariable logistic regression to determine factors associated with each treatment strategy.From 1993 to 2010, there were over 101 million outpatient visits for men with a diagnosis of BPH/LUTS. Among these visits, the use of BPH medication increased from 14% of visits in 1993-1995 to over 40% of visits in 2008-2010 (P <.001). After tamsulosin was FDA approved, providers were twice as likely to prescribe ABs (odds ratio 2.35; 95% confidence interval 1.60-3.43). Providers were 5 times as likely to prescribe combination therapy after level 1 evidence supported its use (odds ratio 5.13; 95% confidence interval 3.35-7.86).Over the last 15 years, there has been a steady increase in the use of medications to manage men with BPH. Providers seem to have readily adopted novel medications and treatment regimens in response to FDA approval and supportive level 1 evidence.
Project description:This study aimed to investigate perceived ejaculatory function/satisfaction before treatment for lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) and to identify associations between specific categories of ejaculatory dysfunctions (EjDs) and LUTS. A total of 1574 treatment-naïve men with LUTS/BPH were included in this study. All patients underwent routine evaluation for LUTS/BPH including the International Index of Erectile Function and a 5-item questionnaire developed to assess ejaculatory volume/force/pain/satisfaction/latency time. Patients who had sexual intercourse over the past 4 weeks were classified as sexually active group. A total of 783 patients were categorized as sexually active group. Decreased ejaculatory volume and force were reported by 53.4% and 55.7% of 783 sexually active men, respectively. There was a strong correlation between ejaculatory volume and force. Ejaculatory pain/discomfort, premature ejaculation (PE), and delayed ejaculation (DE) were reported in 41.0%, 16.3%, and 41.4% of the patients, respectively. Over 40.0% of men without decreased ejaculation volume/force were satisfied with ejaculatory function, whereas approximately 6.0% of men with decreased volume/force were satisfied with ejaculatory function. About 30.0% of men with decreased volume/force had orgasmic dysfunction, while approximately 10.0% of men without decreased volume/force did. Decreased ejaculatory volume or force was associated with LUTS severity after adjusting for other influential factors including testosterone level, erectile function, and prostate size on ultrasonography, but PE or DE or ejaculatory pain/discomfort was not. In conclusion, a considerable portion of men with LUTS/BPH appear to have a variety of EjDs. Ejaculatory volume/force and satisfaction/orgasm do not always appear to be concordant. Ejaculatory volume or force is independently associated with LUTS severity, whereas PE or DE or ejaculatory pain/discomfort is not.
Project description:ContextSeveral newer device-based procedures have recently become available for treating men with lower urinary tract symptoms attributed to benign prostatic hyperplasia, but their effectiveness remains uncertain.ObjectiveTo assess the longer-term comparative effectiveness (defined as >12 mo of follow-up) of the newer treatment modalities prostatic urethral lift (PUL), transurethral prostate convective radiofrequency water vapor (Rezūm), Aquablation, and prostatic arterial embolization (PAE).Evidence acquisitionOvid Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), and the Agency for Healthcare Research and Quality databases were searched through September 30, 2019; hand searches of references of relevant studies were also performed. Eligible studies were randomized controlled trials (RCTs) published in English language. We excluded observational studies.Evidence synthesisOne RCT (n = 91) found that patients undergoing PUL may be less likely to respond (risk ratio [RR] 0.8; 95% confidence interval [CI] 0.7-1.0; low certainty of evidence [CoE]) and have a higher mean International Prostate Symptom Score (IPSS; mean difference 6.1; 95% CI 2.2-10.0; low CoE) than those undergoing transurethral resection of the prostate (TURP). Among patients undergoing PAE, one small RCT (n = 30) reported similar IPSS response rates (RR 0.9; 95% CI 0.7-1.1; low CoE) and one trial (n = 107) found similar mean IPSS (-0.7; 95% CI -1.3 to 2.7; moderate CoE) scores to those among patients undergoing TURP. A single study on Aquablation reported 12 mo of follow-up only, and a single 3-mo trial compared Rezūm with sham treatment.ConclusionsThe current best evidence underlying these newer therapies is limited to few trials (PUL and PAE), short-term follow-up of 12 mo (Aquablation and Rezūm), or sham comparison only (Rezūm).Patient summaryEvidence for four of the newer surgical treatments for men with an enlarged prostate is limited to few small trials with short-term follow-up; only one trial compared a new treatment modality with sham surgery.
Project description:PURPOSE:To review the role of a persistent prostatic inflammatory status (PIS) in the development and progression of benign prostatic hyperplasia (BPH) associated with lower urinary tract symptoms (LUTS) and which medical therapies approved for LUTS/BPH may reduce persistent PIS. METHODS:Literature search in PubMed up to July 2019. RESULTS:The cause of histologically defined persistent PIS or chronic prostatic inflammation is multifactorial. It is evident in many men with LUTS/BPH, particularly in older men and in men with a large prostate volume or more severe (storage) LUTS. Additionally, persistent PIS is associated with an increased risk of acute urinary retention and symptom worsening. Of medical therapies approved for LUTS/BPH, the current evidence for a reduction of persistent PIS is greatest for the hexanic extract of Serenoa repens (HESr). This treatment relieves LUTS to the same extent as ?1-adrenoceptor antagonists and short-term 5?-reductase inhibitors. Limited evidence is available on the effect of other mainstream LUTS/BPH treatments on persistent PIS. CONCLUSIONS:Persistent PIS plays a central role in both the development and progression of LUTS/BPH. In men with LUTS/BPH who have a high chance of harbouring persistent PIS, HESr will not only improve LUTS, but also reduce (underlying) inflammation. Well-designed clinical studies, with a good level of evidence, are required to better evaluate the impact of BPH/LUTS medical therapies on persistent PIS.
Project description:BackgroundThe aim of this meta-analysis was to understand the relationship between statin with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS).MethodsA systematic literature search was conducted using PubMed, Embase, Cochrane Library, Chinese Medical and Biological Literature Database, China HowNet, Vip, and Wanfang. We calculated pooled odds ratios (OR) and 95% CI and standardized mean difference (SMD). Using Stata 12.0 and Review 5.3 for meta-analysis.ResultsThis meta-analysis included 11 articles and 49,128 participants. Results show statins could not reduce the incidence of BPH [OR = 0.77 (0.57, 1.03, P = .08]. For patients over 60 years old, statins could reduce the incidence of BPH [OR = 0.35 (0.22, 0.55), P < .0001]. Statins can slow down the progression of LUTS in BPH [SMD = -0.32 (-0.54, -0.10), P = .004], but there is no significant correlation between them in patients taking drugs for less than 1 year.ConclusionStatins have no significant effect on the incidence of BPH, but statins can reduce the risk of BPH for patients over 60 years old. For patients with hyperlipidemia, the duration of medication is more than 1 year, which can slow down the progression of LUTS. However, more high-quality and large sample size studies are needed to further improve and verify.
