Background: As one of the most prevalent chronic non-communicable diseases affecting aging males, the burden of benign prostatic hyperplasia is growing over the world. Our study aims at investigating the potential relationships between various blood biomarkers and benign prostatic hyperplasia (BPH) in middle-aged and older men in European and East Asian population cohorts.
Methods: We included 229 022 male adults from the UK Biobank (UKB) and 20 284 male adults from the China Health and Retirement Longitudinal Study (CHARLS) in this study. Forty-four blood biomarkers in UKB cohort and 16 blood biomarkers in the CHARLS cohort were analysed to examine their association with benign prostatic hyperplasia. Cox, logistic analyses and restricted cubic spline models were used to investigate linear and nonlinear longitudinal associations.
Results: In our research, elevated high-density lipoprotein cholesterol showed significant associations with a decreased risk of benign prostatic hyperplasia, and these associations remained significant after accounting for potential covariates both in UKB cohort (hazard ratio (HR) = 0.83; 95% CI = 0.79-0.88, P < 0.001) and CHARLS cohort (odds ratio (OR) = 0.992; 95% CI = 0.985-0.999, P = 0.033). Apolipoprotein A was also found to be inversely associated with BPH (HR = 0.76; 95% CI = 0.70-0.81, P < 0.001). L-shaped relationships were discovered between level of high-density lipoprotein cholesterol and apolipoprotein A with incidence of benign prostatic hyperplasia.
Conclusions: This large prospective biomarker-based study highlights that high-density lipoprotein (HDL) cholesterol and apolipoprotein A are significant protective factors against the development of BPH, with L-shaped associations suggesting an optimal protective range. In contrast, biomarkers related to glucose metabolism, inflammation, and hormone levels were not found to significantly influence BPH progression. Our findings support the potential involvement of lipid biomarkers in the early stages of BPH development, suggesting that future strategies should prioritise lipid-related pathways in the prevention and management of BPH.

Tadalafil is a selective phosphodiesterase type 5 (PDE5) inhibitor commonly used for the treatment of erectile dysfunction and benign prostatic hyperplasia. Its mechanism of action involves the inhibition of PDE5, leading to increased levels of nitric oxide and cyclic guanosine monophosphate in the corpus cavernosum, which facilitates smooth muscle relaxation. This article reviews studies using tadalafil in the treatment of cardiovascular diseases and emphasizes its potential advantages in conditions such as pulmonary arterial hypertension, atherosclerosis, coronary artery disease, myocardial infarction, heart failure, stroke, diabetic ulcers, and cardiomyopathy.

Purpose: The purpose of this study was to investigate the efficacy of Transurethral Holmium Laser of the Prostate (HoLEP) with Double-n Technology in the treatment of benign prostatic hyperplasia (BPH), with a focus on preserving sexual function postoperatively.
Methods: Conducted as a multicenter, prospective, single-blind randomized controlled trial, this study enrolled sexually active male patients with BPH. Participants were randomized into three groups: standard HoLEP (Group A), single-n technology (Group B), and innovative double-n technology (Group C), which emphasizes the preservation of the urethral mucosa and nearby structures.

Purpose: To evaluate the feasibility, safety, and short-term (3-month) results of transperineal prostate thermal ablation (TPTA) as a minimally invasive outpatient treatment for benign prostatic hyperplasia (BPH).
Materials And Methods: A prospective nonrandomized study of 25 patients with lower urinary tract symptoms secondary to BPH seeking care at 2 interventional radiology centers between March and July 2024. TPTA was performed using a 17G radiofrequency needle with a 10-mm active tip under unconscious sedation combined with bilateral perineal and periprostatic nerve blocks.

Introduction: Transurethral resection of the prostate (TURP) is the gold standard surgical treatment to lower urinary tract symptoms and benign prostatic obstruction (LUTS/BPO). Although it has been proven to have substantial efficacy in improving functional outcomes, it has shown a high incidence of complications, including transurethral resection syndrome, massive bleeding, urinary incontinence and sexual dysfunction. High-frequency irreversible electroporation (H-FIRE) is a novel non-thermal ablation technique that delivers pulsed high-voltage but low-energy electric current to the cell membrane, thereby leading to cell death.

This study aimed to investigate the relationship between bone mineral density (BMD), body mass index (BMI), and trabecular bone score (TBS) among middle-aged and older men with or without benign prostatic hyperplasia (BPH).
Methods: A retrospective study was conducted using health examination data from male participants aged 50-98 years collected at a regional hospital in southern Taiwan.
