Benign prostatic hyperplasia (BPH) is a prevalent condition affecting aging men, necessitating a comprehensive and evidence-based approach to diagnosis and management. This manuscript, through the summarization of the latest evidence, aims to establish a consensus among clinicians regarding optimal strategies for diagnosing and managing BPH, to improve patient care and outcomes in clinical practice. A panel of urologists conducted a comprehensive review of the literature by searching various databases and search engines (PubMed, Google Scholar, and Cochrane databases). They identified relevant studies on the diagnosis and management of BPH. The literature was summarized and analyzed to develop 14 statements. The panel utilized a Delphi methodology over two rounds (R1 and R2) to reach a consensus on the statements, considering both the literature evidence and expert opinions. The expert panel reached a consensus on 14 statements addressing diverse aspects of BPH, including tailored therapies for different patient profiles and the necessity for a unified diagnosis and management algorithm to enhance patient outcomes. In conclusion, a unified approach to diagnosing and managing BPH promotes consistent and effective patient care. Proper drug selection, considering factors like efficacy and patient-specific characteristics, is crucial for managing BPH. This approach optimizes treatment outcomes and improves the quality of life for BPH patients.

OBJECTIVE: Transperineal laser ablation (TPLA) is a new minimally-invasive surgical treatment for patients with benign prostatic obstruction (BPO). We report the perioperative and mid-term functional results of the first 100 consecutively patients undergoing TPLA at our institution.
METHODS: Clinical data from consecutive patients undergoing TPLA at our institution from April 2021 to July 2023 were prospectively collected. Primary endpoints were the postoperative changes in IPSS, QoL and MSHQ 3-item questionnaires and in Qmax and post-void residual volume (PVR).
RESULTS: Overall, 100 consecutive patients underwent the procedure. Median age and prostate volume were 66 (IQR 60-75) years and 50 (IQR 40-70) ml, respectively. In the cohort, 14 (14%) patients had an indwelling catheter and 81 (81%) were under oral BPO therapy at the time of TPLA. Baseline median Qmax (ml/s) and PVR (ml) were 9.1 (IQR 6.9-12) and 90 (IQR 50-150), respectively, while median IPSS and QoL were 18 (IQR 15-23) and 4 (IQR 3-4). At all the follow-up timepoints, the evaluated outcomes on both symptoms and functional parameters showed a statistically significant improvement (p < 0.001). Antegrade ejaculation was preserved in all sexually active patients. No postoperative Clavien-Dindo > 2 complications were recorded.
CONCLUSIONS: TPLA represents a safe option for selected well-informed patients swith LUTS due to BPO. Our prospective study confirms the feasibility and favorable perioperative and functional outcomes in a real-world cohort with heterogenous prostate volumes and patient characteristics.

BACKGROUND: Transurethral holmium laser enucleation of the prostate (HoLEP) has a good therapeutic effect on benign prostatic hyperplasia (BPH). The purpose of this study was to investigate the clinical efficacy of HoLEP in the treatment of high-risk elderly patients with BPH and assess its impact on the inflammatory response, vascular endothelial function and quality of life (QoL).
METHODS: Patients at high risk of BPH who were hospitalised in Chengde Central Hospital from February 2021 to December 2022 were retrospectively selected as the study objects, and a total of 100 cases were included. The control group underwent transurethral resection of the prostate, and the observation group underwent HoLEP. Perioperative indexes, urodynamic indexes, QoL 6 months after surgery and incidence of postoperative complications were compared between the two groups. Moreover, serum levels of inflammatory factors and vascular endothelial factors were detected in two groups.
RESULTS: We found no significant difference in general data between the two groups of patients (p > 0.05). The operation time, perioperative bleeding, bladder flushing time and hospitalisation time of the observation group were significantly shorter than those of the control group (p < 0.05). On the 7th day after surgery, the serum levels of tumour necrosis factor alpha, interleukin-1β, interleukin-6, vascular endothelial growth factor, basic fibroblast growth factor and endothelin-1 in the observation group were significantly lower than those in the control group (p < 0.05). Six months after surgery, the maximal urinary flow rate and QoL scores of the patients in the observation group were significantly higher than those of the control group (p < 0.05), and the residual urine volume and International Prostate Symptom Score of observation group were significantly lower than those of the control group (p < 0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group (χ2 = 7.440, p = 0.006).
CONCLUSIONS: HoLEP can effectively remove hyperplasia of the prostate and reduce the inflammatory response in the patient\'s body when treating BPH in high-risk elderly patients. It can also regulate the levels of vascular endothelial factors and effectively improve the patient\'s QoL.

BACKGROUND: Benign prostatic hyperplasia (BPH) is a common health disorder of the male genitourinary system with a high prevalence, especially among middle-aged and older adults, which seriously affects men\'s quality of life. Inflammatory markers derived from complete blood cell count (CBC) have previously been considered a prognostic indicator for various diseases, but little is known about their relationship with BPH. This study evaluated the relationship between complete blood cell count (CBC)-derived inflammatory biomarkers and BPH.
METHODS: Data for this cross-sectional study were gathered from the National Health and Nutrition Examination Survey (NHANES) between 2001 and 2008. Using multiple logistic regressions, the study examined the association between benign prostatic hyperplasia(BPH) and Inflammatory biomarkers derived from blood cell counts such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), Systemic Inflammatory Response Index (SIRI) and Systemic Immunoinflammatory Index (SII).
RESULTS: 3,919 participants were included, with a median age of 61.00 (52.00-71.00) years old. Among them, 609 participants had benign prostatic hyperplasia, with a prevalence of 15.54%. Upon accounting for confounding factors, the study revealed a positive correlation between the plurality of BPH PLR and SII. However, MLR, NLR, and SIRI did not significantly correlate with the prevalence of BPH (p>0.05). In contrast to the lowest quartile, higher quartiles of PLR (OR = 1.93[1.38-2.69]) and SII (OR = 1.71[1.22-2.40]) were linked to an elevated risk of BPH. Interaction tests showed that age, body mass index, hypertension, diabetes, smoking, and drinking had no significant effect on this positive correlation (p for interaction>0.05). In addition, we found a roughly linear association between SII, PLR, and BPH using smoothed curve fitting.
CONCLUSIONS: According to our research, high levels of PLR and SII are positively linked with an increased risk of BPH in middle-aged and elderly individuals in the United States. The results compensate for previous studies that still need to be validated with larger prospective cohorts.

OBJECTIVE: To evaluate the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) in a large prospective cohort of patients with benign prostatic hyperplasia (BPH) through systematic follow-up at a single institution.
METHODS: Clinical outcomes were analyzed between August 2008 and June 2022. Patients were followed-up at 2 weeks, 3 months and 6 months postoperatively.
RESULTS: A total of 3,000 patients (mean age, 69.6±7.7 years) underwent HoLEP. Baseline total International Prostate Symptom Score (IPSS) was 19.3±7.7 and maximum flow rate (Qmax) was 9.4±4.8 mL/s. Mean total prostate volume was 67.7±3.4 mL. Total operation time was 60.7±31.5 minutes, and catheterization time was 1.0 days (range, 1.0-1.0 days). At 6 months postoperatively, the total IPSS decreased to 6.6±5.8 and Qmax increased to 22.2±11.3 mL/s. Complications at 6 months postoperatively included stress urinary incontinence (SUI) in 36 patients (1.9%), urgency urinary incontinence (UUI) in 25 (1.3%), bladder neck contracture (BNC) requiring transurethral incision (TUI) in 16 (0.5%), and urethral stricture in 29 (1.0%). Eleven patients (0.4%) with prostatic fossa stones required stone removal. Sixty-one patients (2.0%) required secondary surgery (transurethral coagulation, 16 [0.5%]; TUI for BNC, 16 [0.5%]; stone removal for prostatic fossa stones, 11 [0.4%]; and endoscopic internal urethrotomy for urethral stricture, 18 [0.6%]).
CONCLUSIONS: Mid-term follow-up results after HoLEP in BPH patients showed excellent efficacy and low complication rates. Unlike previous reports, the incidence of SUI and UUI after HoLEP was low, but the occurrence of de novo stone formation in prostatic fossa was notable.

OBJECTIVE: Benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are prevalent urological ailments in elderly males. Numerous clinical studies have revealed an invert association between BPH/prostate size and PCa growth. This study investigates the association between prostate size and total glandular tissue volume of the peripheral zone (GVPZ) using a unique blend of magnetic resonance imaging (MRI) and histo-anatomical imaging technique.
METHODS: Patients were selected who underwent both radical prostatectomy and preoperative MRI scans. MRI scans provided quantitative measurements of prostatic zone dimensions, while histo-anatomical slides yielded quantitative data on glandular density of the peripheral zone (PZ) using imaging software. Integration of MRI and histopathology enabled the assessment of the GVPZ. Statistical analysis identified relationships between total prostate volume (TPV) and GVPZ.
RESULTS: Seventy-two patients were selected and 40 cc was determined to be the optimal cutoff for small-to-moderate versus large prostates. Once the two subgroups in TPV were formed, the relationship between TPV and GVPZ was found to be highly significant (p<0.001).
CONCLUSIONS: The combination of MRI and histopathology offers a novel approach for precise quantification of glandular tissue within the prostatic PZ. This study corroborates the hypothesis of PZ compression via an enlarging transition zone in larger BPH prostates, resulting in PZ glandular atrophy. Given that most PCa originates in the PZ, these results shed light on the potential protective role of larger BPH prostates against PCa growth.

Benign Prostatic Hyperplasia (BPH) is a complex condition leading to Lower Urinary Tract Symptoms in aging men, characterized by cellular proliferation, smooth muscle dysfunction, inflammation, and fibrosis. While BPH is known to involve heightened macrophage infiltration, the specific contribution of infiltrating monocytes/macrophages to the disease mechanism remains uncertain. This research explores the impact of reducing circulating monocytes and subsequently limiting their tissue infiltration by using Ccr2 knockout (Ccr2-KO) mice. Ccr2-KO and wild type mice were implanted with testosterone and estradiol (T + E2, 25 mg + 2.5 mg) pellets. Urinary function was assessed via weekly void spot assays over 12 weeks, and prostatic macrophage levels were visualized and quantified in tissue sections using an F4/80 antibody. Additionally, Ki-67 staining was used to evaluate cell proliferation, and picrosirius red staining to assess collagen accumulation. Increased voiding frequency which developed in T + E2 mice, was significantly ameliorated in Ccr2-KO mice, however, both Ccr2-KO and wild type (WT) mice showed increased bladder weights after three month, representing a hypertrophic response to bladder outlet obstruction. T + E2 substantially increased the density of macrophages in WT but not Ccr2-KO mouse prostate. Proliferation rate, as indicated by Ki-67 positivity, was elevated in the vental and anterior prostate lobes but was only marginally reduced in Ccr2-KO mice. Most importantly, a significant prostatic collagen accumulation was observed in WT mice that was markedly reduced by Ccr2 deficiency post T + E2 treatment. The absence of Ccr2 mitigates urinary dysfunction and alters prostatic macrophage levels and collagen accumulation in steroid hormone imbalance. These findings suggest a crucial role for monocyte infiltration, giving rise to macrophages or other cell derivatives, to drive fibrosis.
