Comparative efficacy and safety of new surgical treatments for benign prostatic hyperplasia: systematic review and network meta-analysis.

ABSTRACT: OBJECTIVE:To assess the efficacy and safety of different endoscopic surgical treatments for benign prostatic hyperplasia. DESIGN:Systematic review and network meta-analysis of randomised controlled trials. DATA SOURCES:A comprehensive search of PubMed, Embase, and Cochrane databases from inception to 31 March 2019. STUDY SELECTION:Randomised controlled trials comparing vapourisation, resection, and enucleation of the prostate using monopolar, bipolar, or various laser systems (holmium, thulium, potassium titanyl phosphate, or diode) as surgical treatments for benign prostatic hyperplasia. The primary outcomes were the maximal flow rate (Qmax) and international prostate symptoms score (IPSS) at 12 months after surgical treatment. Secondary outcomes were Qmax and IPSS values at 6, 24, and 36 months after surgical treatment; perioperative parameters; and surgical complications. DATA EXTRACTION AND SYNTHESIS:Two independent reviewers extracted the study data and performed quality assessments using the Cochrane Risk of Bias Tool. The effect sizes were summarised using weighted mean differences for continuous outcomes and odds ratios for binary outcomes. Frequentist approach to the network meta-analysis was used to estimate comparative effects and safety. Ranking probabilities of each treatment were also calculated. RESULTS:109 trials with a total of 13?676 participants were identified. Nine surgical treatments were evaluated. Enucleation achieved better Qmax and IPSS values than resection and vapourisation methods at six and 12 months after surgical treatment, and the difference maintained up to 24 and 36 months after surgical treatment. For Qmax at 12 months after surgical treatment, the best three methods compared with monopolar transurethral resection of the prostate (TURP) were bipolar enucleation (mean difference 2.42 mL/s (95% confidence interval 1.11 to 3.73)), diode laser enucleation (1.86 (-0.17 to 3.88)), and holmium laser enucleation (1.07 (0.07 to 2.08)). The worst performing method was diode laser vapourisation (-1.90 (-5.07 to 1.27)). The results of IPSS at 12 months after treatment were similar to Qmax at 12 months after treatment. The best three methods, versus monopolar TURP, were diode laser enucleation (mean difference -1.00 (-2.41 to 0.40)), bipolar enucleation (0.87 (-1.80 to 0.07)), and holmium laser enucleation (-0.84 (-1.51 to 0.58)). The worst performing method was diode laser vapourisation (1.30 (-1.16 to 3.76)). Eight new methods were better at controlling bleeding than monopolar TURP, resulting in a shorter catheterisation duration, reduced postoperative haemoglobin declination, fewer clot retention events, and lower blood transfusion rate. However, short term transient urinary incontinence might still be a concern for enucleation methods, compared with resection methods (odds ratio 1.92, 1.39 to 2.65). No substantial inconsistency between direct and indirect evidence was detected in primary or secondary outcomes. CONCLUSION:Eight new endoscopic surgical methods for benign prostatic hyperplasia appeared to be superior in safety compared with monopolar TURP. Among these new treatments, enucleation methods showed better Qmax and IPSS values than vapourisation and resection methods. STUDY REGISTRATION:CRD42018099583.

Project description:BackgroundAlthough combination therapy with 5 alpha-reductase inhibitor (5ARI) and alpha-blocker is one of the standard interventions in symptomatic benign prostatic hyperplasia (BPH), 5ARI monotherapy is seldom the focus of attention. Adverse events associated with 5ARI include depression and suicidal attempts in addition to persistent erectile dysfunction. The aim of this study is to update our knowledge of clinical efficacy and incidence of adverse events associated with 5ARI treatment in symptomatic BPH.Methods and findingsA meta-analysis of randomized controlled clinical trials (RCTs) from 1966 until March, 2017 was performed using database from PubMed, Cochrane Collaboration and Embase. A total of 23395 patients were included in this study and the inclusion criteria were: RCTs with 5ARI and placebo in symptomatic BPH patients. Parameters included prostate specific antigen (PSA), prostate volume (PV), International Prostate Symptom Score (IPPS), post-void residual urine (PVR), voiding symptoms of IPSS (voiding IPSS), maximum urinary flow rate (Qmax), and adverse events (AEs). A meta-analysis with meta-regression was performed for each effect size and adverse events, sensitivity analysis, cumulative analysis along with the analysis of ratio of means (ROM) in the placebo group. A total of 42 studies were included in this study for review, and a total of 37 studies were included in the meta-analysis, including a total of 23395 patients (treatment group: 11392, placebo group: 12003). The effect size of all variables except PVR showed a significant improvement following 5ARI treatment compared with placebo. However, the effect size of differences showed declining trend in PV, IPSS and Qmax according to recent years of publication. In ROM analysis, PV showed no significant increase in the placebo group, with a ROM of 1.00 (95% CI, 0.88, 1.14). The 5ARI treatment resulted in a significantly higher incidence of decreased libido (OR = 1.7; 95% CI, 1.36, 2.13), ejaculatory disorder (OR = 2.94; 95% CI, 2.15, 4.03), gynecomastia (OR = 2.32; 95% CI, 1.41, 3.83), and impotence (OR = 1.74; 95% CI, 1.32, 2.29). Our study has the following limitations: included studies were heterogeneous and direct comparison of efficacy between alpha blocker and 5ARI was not performed. Adverse events including depression or suicidal attempt could not be analyzed in this meta-analysis setting.ConclusionsAlthough there was a significant clinical benefit of 5ARI monotherapy compared with placebo, the effective size was small. Moreover, the risk of adverse events including sexually related complications were high. Additional head-to-head studies are needed to re-evaluate the clinical efficacy of 5ARI compared with alpha-adrenergic receptor blockers.

Project description:ContextSurgical treatment is important for male lower urinary tract symptom (LUTS) management, but there are few reviews of the risks of reoperation.ObjectiveTo systematically evaluate the current evidence regarding the reoperation rates of surgical treatment for LUTS in accordance with current recommendations and guidelines.Evidence acquisitionEligible studies published up to July 2023, were searched for in the PubMed® (National Library of Medicine, Bethesda, MD, USA), Embase® (Elsevier, Amsterdam, the Netherlands), and Web of Science™ (Clarivate™, Philadelphia, PA, USA) databases. STATA® (StataCorp LP, College Station, TX, USA) software was used to conduct the meta-analysis. Random-effects models were used to calculate the pooled incidences (PIs) of reoperation and the 95% confidence intervals (CIs).Evidence synthesisA total of 119 studies with 130,106 patients were included. The reoperation rate of transurethral resection of the prostate (TURP) at 1, 2, 3, and 5 years was 4.0%, 5.0%, 6.0%, and 7.7%, respectively. The reoperation rate of plasma kinetic loop resection of the prostate (PKRP) at 1, 2, 3, and 5 years was 3.5%, 3.6%, 5.7%, and 6.6%, respectively. The reoperation rate of holmium laser enucleation of the prostate (HoLEP) at 1, 2, 3, and 5 years was 2.4%, 3.3%, 5.4%, and 6.6%, respectively. The reoperation rate of photoselective vaporization of the prostate (PVP) at 1, 2, 3, and 5 years was 3.3%, 4.1%, 6.7%, and 7.1%, respectively. The reoperation rate of surgery with AquaBeam® at 1, 2, 3, and 5 years was 2.6%, 3.1%, 3.0%, and 4.1%, respectively. The reoperation rate of prostatic artery embolization (PAE) at 1, 2, 3, and 5 years was 12.2%, 20.0%, 26.4%, and 23.8%, respectively. The reoperation rate of transurethral microwave thermotherapy (TUMT) at 1, 2, 3, and 5 years was 9.9%, 19.9%, 23.3%, and 31.2%, respectively. The reoperation rate of transurethral incision of the prostate (TUIP) at 5 years was 13.4%. The reoperation rate of open prostatectomy (OP) at 1 and 5 years was 1.3% and 4.4%, respectively. The reoperation rate of thulium laser enucleation of the prostate (ThuLEP) at 1, 2, and 5 years was 3.7%, 7.7%, and 8.4%, respectively.ConclusionOur results summarized the reoperation rates of 10 surgical procedures over follow-up durations of 1, 2, 3, and 5 years, which could provide reference for urologists and LUTS patients.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO, identifier CRD42023445780.

Project description:ContextBenign prostatic hyperplasia (BPH) associated with lower urinary tract symptoms (LUTS) is diagnosed in up to 80% of men during their lifetime. Several novel ultra-minimally invasive surgical treatments (uMISTs) for BPH/benign prostatic obstruction (BPO) have become available over the past 5 yr.ObjectiveTo evaluate the perioperative and functional outcomes of recently introduced uMISTs for BPH/BPO, including Urolift, Rezūm, temporary implantable nitinol device, prostatic artery embolization (PAE), and intraprostatic injection.Evidence acquisitionA systematic literature search was conducted in December 2020 using Medline (via PubMed), Embase (via Ovid), Scopus, and Web of Science (registered on PROSPERO as CRD42021225014). The search strategy used PICO criteria and article selection was conducted in accordance with the PRISMA guidelines. The risk of bias and the quality of the articles included were assessed. A dedicated data extraction form was used to collect the data of interest. Pooled and cumulative analyses were performed to compare perioperative and functional outcomes between study groups. A random-effects model using the DerSimonian and Laird method was used to evaluate heterogeneity. Stata version 15.0 software was used for all statistical analyses.Evidence synthesisThe initial electronic search identified 3978 papers, of which 48 ultimately met the inclusion criteria and were included in the analysis. Pooled analysis revealed a uMIST benefit in terms of International Prostate Symptom Score (IPSS; -9.81 points, 95% confidence interval [CI] -11.37 to -8.25 at 1 mo; -13.13 points, 95% CI -14.98 to -11.64 at 12 mo), maximum flow rate (from +3.66 ml/s, 95% CI 2.8-4.5 to +4.14 ml/s, 95% CI 0.72-7.56 at 12 mo), and postvoid residual volume (-10.10 ml, 95% CI -27.90 to 7.71 at 12 mo). No negative impact was observed on scores for the International Index of Erectile Function-5, Male Sexual Health Questionnaire-Ejaculatory Dysfunction bother and function scales (overall postintervention change in pooled median score of 1.88, 95% CI 1.34-2.42 at the start of follow-up; and 1.04, 95% CI 0.28-1.8 after 1 yr), or the IPSS-Quality of Life questionnaire.ConclusionsNovel uMISTs can yield fast and effective relief of LUTS without affecting patient quality of life. Only Rezūm, UroLift, and PAE had a minimal impact on patients' sexual function with respect to baseline, especially regarding preservation of ejaculation.Patient summaryWe reviewed outcomes for recently introduced ultra-minimally invasive surgical treatments for patients with lower urinary tract symptoms caused by benign prostate enlargement or obstruction. The evidence suggests that these novel techniques are beneficial in terms of controlling symptoms while preserving sexual function.Take home messageNovel ultra-minimally invasive treatments can yield fast and effective relief of lower urinary tract symptoms without affecting a patient's quality of life.
