Krishnamoorthi R, Ganapathy A A, Hari Priya VM, Kumaran A. Future aspects of plant derived bioactive metabolites as therapeutics to combat benign prostatic hyperplasia. JOURNAL OF ETHNOPHARMACOLOGY 2024; 330:118207. [PMID: 38636573 DOI: 10.1016/j.jep.2024.118207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 04/12/2024] [Accepted: 04/14/2024] [Indexed: 04/20/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Benign prostatic hyperplasia (BPH), characterized by prostate enlargement due to cell proliferation, is a common urinary disorder in men over 50, manifesting as lower urinary tract symptoms (LUTS). Currently, several therapeutic options are accessible for treating BPH, including medication therapy, surgery and watchful waiting. Conventional drugs such as finasteride and dutasteride are used as 5α-reductase inhibitors for the treatment of BPH. However long-term use of these drugs is restricted due to their unpleasant side effects. Despite the range of available medical therapies, the effective treatment against BPH is still inadequate. Certain therapeutic plants and their phytochemicals have the aforementioned goals and work by regulating this enzyme. AIM OF THE STUDY This review aims to provide a comprehensive insight to advancements in diagnosis of BPH, modern treatment methods and the significance of ethnobotanically relevant medicinal plants as alternative therapeutics for managing BPH. MATERIAL AND METHODS A thorough and systematic literature search was performed using electronic databases and search engines such as PubMed, Web of Science, NCBI and SciFinder till October 2023. Specific keywords such as "benign prostatic hyperplasia", "medicinal plants", "phytochemicals", "pharmacology", "synergy", "ethnobotany", "5-alpha reductase", "alpha blocker" and "toxicology". By include these keywords, a thorough investigation of pertinent papers was assured, and important data about the many facets of BPH could be retrieved. RESULTS After conducting the above investigation, 104 herbal remedies were found to inhibit Phosphodiesterase-5 (PDE-5) inhibition, alpha-blockers, or 5α -reductase inhibition effects which are supported by in vitro, in vivo and clinical trial studies evidence. Of these, 89 plants have ethnobotanical significance as alpha-blockers, alpha-reductase inhibition, or PDE-5 inhibition, and the other fifteen plants were chosen based on their ability to reduce BPH risk factors. Several phytocompounds, including, rutaecarpine, vaccarin, rutin, kaempferol, β-sitosterol, quercetin, dicaffeoylquinic acid, rutaevin, and phytosterol-F have been reported to be useful for the management of BPH. The use of combination therapy offers a strong approach to treating long-term conditions compare to single plant extract drugs. Furthermore, several botanical combinations such as lycopene and curcumin, pumpkin seed oil and saw palmetto oil, combinations of extracts from Funtumia africana (Benth.) Stapf and Abutilon mauritianum (Jacq.) Medik., and Hypselodelphys poggeana (K.Schum.) Milne-Redh. and Spermacoce radiata (DC.) Sieber ex Hiern are also supported through in vitro and in vivo studies for managing BPH through recuperation in patients with chronic long-term illnesses, as measured by the International Prostate Symptom Score. CONCLUSION The review proposes and endorses careful utilization of conventional medications that may be investigated further to discover possible PDE-5, 5 alpha-reductase, an alpha-blocker inhibitor for managing BPH. Even though most conventional formulations, such as 5 alpha-reductase, are readily available, systemic assessment of the effectiveness and mechanism of action of the herbal constituents is still necessary to identify novel chemical moieties that can be further developed for maximum efficacy. However, there exist abundant botanicals and medicinal plants across several regions of Africa, Asia, and the Americas, which can be further studied and developed for utilization as a potential phytotherapeutic for the management of BPH.

[PMID: 38558096 DOI: 10.1002/pros.24697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Revised: 02/17/2024] [Accepted: 03/18/2024] [Indexed: 04/04/2024]
Abstract
PURPOSE Holmium laser enucleation of the prostate (HoLEP) is a surgical treatment option for benign prostatic hyperplasia (BPH). Many men develop retrograde ejaculation postprocedure, but there is conflicting evidence regarding sexual function outcomes post-HoLEP. We sought to examine significant variations in patient-reported erectile and ejaculatory function within 12 months post-HoLEP. MATERIALS AND METHODS We conducted a retrospective study for patients who underwent HoLEP between Nov 2018 and Feb 2022. Of the reviewed patients, 277 patients met inclusion criteria and completed pre and postoperative questionnaires, which included the Male Sexual Health Questionnaire- Ejaculatory Dysfunction (MSHQ-EJD) and the International Index of Erectile Function/Sexual Health Inventory for Men (IIEF-5/SHIM). Surveys were provided to patients up to 12 months postprocedure. Demographics and comorbidities associated with sexual dysfunction were collected. Responses to each question were analyzed to detect sub-categorical variations in sexual function as the secondary objective. Data was analyzed by using a linear mixed model. RESULTS There was a significant decline in total scores for the MSHQ-EJD (8.70 pre-HoLEP vs. 6.58 post HoLEP, p ≤ 0.001) including a significant decline (p < 0.005) in questions 1-3 which assess ejaculatory ability, strength, and volume. There was not a significant decline in question 4 which assesses bother (2.552 pre-HoLEP vs. 3.119 post-HoLEP, p = 0.526). There was not a significant decline in the IIEF-5/SHIM postoperatively (11.51 pre-HoLEP vs. 13.327 post-HoLEP, p = 0.498). CONCLUSIONS Patients undergoing HoLEP do not experience a decline in erectile function. Patients do experience a decline in ejaculatory function but did not find this bothersome.

Efficacy of a Novel Prophylactic Scheme of Fosfomycin Trometamol in Patients Undergoing Endoscopic Surgery for Benign Prostatic Hyperplasia: Findings from a Prospective Monocentric Single-Arm Study. Antibiotics (Basel) 2024; 13:424. [PMID: 38786152 PMCID: PMC11117375 DOI: 10.3390/antibiotics13050424] [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: 04/16/2024] [Revised: 04/26/2024] [Accepted: 05/03/2024] [Indexed: 05/25/2024] Open
Abstract
This study aimed to assess the efficacy of a novel prophylactic scheme of fosfomycin trometamol in patients undergoing elective HoLEP (holmium laser enucleation of the prostate) or TURP (transurethral resection of the prostate) procedures for treating benign prostatic hyperplasia. Patients affected by benign prostatic hyperplasia and undergoing elective HoLEP or TURP procedures during the period February 2022-June 2023 were prospectively enrolled. Two 3 g oral fosfomycin trometamol doses 12 h apart were administered at 8.00 p.m. on day -1 (i.e., the day before HoLEP or TURP procedure) and at 8.00 a.m. on day 0 (i.e., the day of the surgical procedure). The following outcomes were assessed: prevalence of fever occurring in the first 48 h after surgical procedure; prevalence of urological complications occurring after the surgical procedure; prevalence of proven urinary tract infections (UTIs) and/or bloodstream infections (BSIs) at 14 days post-procedure; and prevalence of emergency department admission for UTI-related sepsis at 14 days post-procedure. Univariate analysis comparing patients with and without proven UTI, BSI, or emergency department admission at 14 days post-procedure was carried out. Overall, 96 patients (median age 70 years) undergoing HoLEP (82.3%) or TURP (17.7%) were prospectively included. Median (IQR) time of surgical procedure after the morning fosfomycin dose was 226.5 min (range 88.5-393.75 min). Fever in the post-surgical 48 h occurred in 3/96 patients (3.1%). Prevalence of proven UTI at 14 days was as low as 1.0% (1/96), whereas no patient had proven BSI or UTI-related sepsis requiring emergency department admission at 14 days. Our findings support the contention that a prophylactic scheme based on two doses of fosfomycin trometamol 12 h apart before surgical intervention may represent a valuable strategy for preventing infectious complications in urologic patients undergoing HoLEP or TURP. Larger definitive confirmatory studies are warranted.

Abstract
Benign prostatic hyperplasia (BPH), a prevalent condition in older men, is often managed through various surgical interventions. This narrative review aims to explore the impact of these surgical treatments on sexual function, a critical aspect of patient quality of life often overlooked in BPH management. The methodology encompassed a thorough review of contemporary surgical techniques for BPH, including prostate resection, enucleation, vaporization, and minimally invasive therapies such as UroLift, Rezum, and Aquablation. Additionally, the focus was on patient-centered outcomes, with a special emphasis on sexual health following surgery. Findings reveal that, while surgical interventions effectively alleviate BPH symptoms, they often have significant repercussions in sexual function, including erectile and ejaculatory dysfunction. However, emerging techniques demonstrate potential in preserving sexual function, underscoring the need for patient-centric treatment approaches. The study highlights the complex interplay between BPH surgery and sexual health, with minimally invasive treatments showing promise in balancing symptom relief and sexual function preservation. In conclusion, the study advocates for an integrated, interdisciplinary approach to BPH treatment, emphasizing the importance of considering sexual health in therapeutic decision-making. This narrative review suggests a paradigm shift towards minimally invasive techniques could optimize patient outcomes, marrying symptom relief with quality-of-life considerations. The need for further research in this domain is evident, particularly in understanding long-term sexual health outcomes following different surgical interventions for BPH.

Abstract
INTRODUCTION This study compares the clinical and microbiological efficacy of ceftolozane/tazobactam (CTLZ/TAZ) and piperacillin/tazobactam (PIPC/TAZ) for treating complicated cystitis or acute pyelonephritis. METHODS Patients who had been treated with empiric antibiotics, CTLZ/TAZ (52 cases) or PIPC/TAZ (47 cases), due to urinary tract infections (UTIs) were eligible for this study. Patients' demographic backgrounds, types of UTIs, and causative microorganisms isolated from urine or blood bacterial cultures were collected. Short-term clinical efficacy at the end of the initial empiric therapy, long-term clinical efficacy including sequential antibiotic treatments (nonrecurrence rate within 1 month after the initial empiric therapy), and microbiological efficacy were retrospectively compared in both CTLZ/TAZ and PIPC/TAZ groups. RESULTS Complicated UTIs were present in most eligible patients, and no significant difference in the patients' background was observed between the two groups. Escherichia coli and Enterococcus faecalis were the most common microorganisms isolated from urine culture in both groups. The short-term clinical effective rate of CTLZ/TAZ and PIPC/TAZ was 80.8% and 87.2%, respectively. For long-term clinical efficacy, the nonrecurrence rate of UTIs was present in 95.1% and 89.7% of patients with CTLZ/TAZ and PIPC/TAZ, respectively. No significant difference was observed in the short- and long-term effects between the two groups. The microbiological efficacy of the CTLZ/TAZ and PIPC/TAZ groups was 72.7% and 86.0%, respectively. No significant difference in microbiological effects was also observed between the two groups. CONCLUSIONS This study demonstrated the noninferiority of CTLZ/TAZ to PIPC/TAZ, suggesting that CTLZ/TAZ is an alternative antibiotic used as empiric therapy for UTIs.

Abstract
Autophagy is a lysosomal degradation process known as autophagic flux, involving the engulfment of damaged proteins and organelles by double-membrane autophagosomes. It comprises microautophagy, chaperone-mediated autophagy (CMA), and macroautophagy. Macroautophagy consists of three stages: induction, autophagosome formation, and autolysosome formation. Atg8-family proteins are valuable for tracking autophagic structures and have been widely utilized for monitoring autophagy. The conversion of LC3 to its lipidated form, LC3-II, served as an indicator of autophagy. Autophagy is implicated in human pathophysiology, such as neurodegeneration, cancer, and immune disorders. Moreover, autophagy impacts urological diseases, such as interstitial cystitis /bladder pain syndrome (IC/BPS), ketamine-induced ulcerative cystitis (KIC), chemotherapy-induced cystitis (CIC), radiation cystitis (RC), erectile dysfunction (ED), bladder outlet obstruction (BOO), prostate cancer, bladder cancer, renal cancer, testicular cancer, and penile cancer. Autophagy plays a dual role in the management of urologic diseases, and the identification of potential biomarkers associated with autophagy is a crucial step towards a deeper understanding of its role in these diseases. Methods for monitoring autophagy include TEM, Western blot, immunofluorescence, flow cytometry, and genetic tools. Autophagosome and autolysosome structures are discerned via TEM. Western blot, immunofluorescence, northern blot, and RT-PCR assess protein/mRNA levels. Luciferase assay tracks flux; GFP-LC3 transgenic mice aid study. Knockdown methods (miRNA and RNAi) offer insights. This article extensively examines autophagy's molecular mechanism, pharmacological regulation, and therapeutic application involvement in urological diseases.

[PMID: 37682158 PMCID: PMC10489449 DOI: 10.1097/md.0000000000035008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 08/08/2023] [Indexed: 09/09/2023] Open
Abstract
Benign prostatic hypertrophy (BPH) is associated with autonomic dysfunction and sympathetic nervous system mediated by the alpha receptor. However, limited data exist regarding the effects of the beta-blocker (BB) carvedilol on arrhythmia and urologic outcomes in BPH patients. Our database of patients diagnosed with BPH from 2015 to 2020 was used to obtain echocardiography and electrocardiogram data. Inclusion criteria were BPH patients taking BBs. International Prostate Symptom Score questionnaire were used to evaluate the urinary symptoms and quality of life. Among 448 patients with BPH (69.2 ± 10.9 years) taking BBs, 219 patients took carvedilol (48.9%) and 229 patients took a non-carvedilol BB (51.1%; bisoprolol, 184 patients, 80% or nebivolol, 45 patients, 20%). Difference in the baseline characteristics was not observed. During the median 36-month follow-up, a lower incidence of arrhythmic events (P = .029), total urologic events (P < .001), and less use of additive alpha-blocker was observed in the carvedilol group (P = .022). In multivariate analysis, less carvedilol use (P = .019), heart failure (P < .001), stroke (P < .001), and cardiomyopathy (P = .046) were independent risk factors for arrhythmic events. In addition, less carvedilol use (P = .009) and older age (P = .005) were independent risk factors for urologic events based on BB type at the median 36-month follow-up. The use of carvedilol was associated with less arrhythmic events in BPH patients with palpitation and decreased the incidence of urologic events in BPH compared with the use of non-carvedilol BBs in long-term follow-up.

Abstract
Benign prostatic hypertrophy (BPH) is a condition where the prostate becomes enlarged. It affects all men and is part of the ageing process. Globally, the incidence rates of BPH have risen by 70% between 2000-2019. When left untreated, it can lead to acute urinary retention, impaired bladder emptying, urinary tract infections, bladder stones, kidney failure or gross haematuria. In this article, Linda Nazarko describes the causes and consequences of BPH along with treatment options that are available for it.

Abstract
OBJECTIVE To compare postoperative outcomes of 3 types of endourologic surgeries (trans-urethral resection of the prostate [TURP], laser vaporization [LVP], and laser enucleation [LEP]) for benign prostatic hypertrophy (BPH) treatment using the ACS-NSQIP database. METHODS The ACS-NSQIP database was queried for men who underwent TURP, PVP, and LEP for treatment of BPH from 2011 till 2019. Demographics, clinical, operative characteristics, and 30-day outcomes were compared. Univariate and multivariate regression models were constructed. Propensity score matching was then performed as a sensitivity analysis. RESULTS A total of 74,273 patients underwent endourologic surgeries for BPH, 65.4% had TURP, 28.6% PVP, and 5.9% LEP. Patients undergoing TURP were more likely to be older with higher ASA class, abnormal labs, and comorbidities (diabetic, congestive heart failure, and bleeding requiring transfusion) (P-value <.001). After adjusting for covariates and propensity score matching, LVP demonstrated shorter hospital stays, shorter operative times, less reoperation rates, decreased DVT/PE risk, with, however, higher odds of urinary tract infection and sepsis as compared to TURP (P-value<.028). Furthermore, LEP was found to have shorter hospital stays, longer operative times, and decreased odds of urinary tract infections and sepsis as compared to TURP (P-value<.006). CONCLUSION LVP and LEP showed better surgical outcomes and characteristics as compared to TURP. Further research is needed to account for longer duration of follow-up and patient-specific urologic outcomes, such as prostate size, urinary incontinence, erectile dysfunction, and retrograde ejaculation.

Abstract
Background Benign prostatic hyperplasia is a common benign disease occurs in older men. Some patients can be treated medically but eventually, most of them will need a surgical intervention, and the most commonly applied procedure is transurethral resection of the prostate (TURP). Objectives The objective of this study is to assess the feasibility and safety of performing transurethral resection of large prostate (80 g and more). Methodology Out of 153 patients reviewed 48 cases included in this study. The main data collected from patients' files and patient interview. The criteria of exclusion were prostate size <80 g and previous history of TURP. The collected data were analyzed by the Statistical Package for the Social Sciences (SPSS). Results The main results showed that 93.7% of patients did not experience major bleeding postoperatively, neither major drop in hemoglobin level. Moreover, the patient's distribution according to the presence of TUR syndrome was only 2.1% with mild symptoms. No patient had an episode of retention during the hospital stay or in the follow-up. Conclusion Surgeon experience, systematic resection approach, and strict time of resection are important factors to assure the safety of TURP in large prostate. In cases of huge prostate size >100 g, staged TURP can be offered safely or if patients' obstructive symptoms do not resolve after the first procedure.

Abstract
PURPOSE Tomato is an important source of lycopene, a carotenoid that has been emerging as a natural preventive agent for prostate disease. Moreover, tomato contains other components with a wide range of physiological properties, but their potential beneficial effects on prostatic hyperplasia (PH) during obesity have not been completely established. In this study, we compared the effect of a lipidic extract of tomato saladette (STE) with Serenoa repens (SR) on obese rats with PH. METHODS Forty-eight Wistar rats were divided in Control (C) and Obese (Ob) treated without (n = 12) and with (n = 36) testosterone enanthate (TE), once a week for 8 weeks to induce PH. After 4 weeks, SR and STE were administered. Biochemical parameters, oxidative stress markers and inflammatory cytokines production were determined. RESULTS TE increased prostate weight and caused prostatic hyperplasia in C group, and these effects were exacerbated by obesity. SR and STE reverted the increase in prostate weight and hyperplasia caused by TE in C and Ob groups. Obesity increased LDL, TGs, NOx and MAD, but decreased HDLc, GSx, SOD and CAT. SR reverted the effects of obesity, but these were significantly reduced and HDLc increased with STE. Obesity and TE increased TNFα, IL-1β and IL-6 levels, but these were partially reverted by STE compared with SR. CONCLUSIONS Excess of fat tissue increases the alterations by PH. STE diminishes these alterations compared with SR, suggesting its beneficial effect to improve prostate function. Whole tomato lipid extract could serve as sole therapy or as an adjunct to pharmacological treatment for PH.

Abstract
Benign prostatic hyperplasia (BPH) is a prevalent illness in older adults. It is well-recognized that testosterone is essential in the onset of BPH. Vildagliptin (Vilda), a dipeptidyl peptidase-IV inhibitor, has been shown to have anti-inflammatory and antioxidant effects. In this study, we studied the effects of vildagliptin on testosterone-induced BPH in rats and its underlying mechanisms. Forty male Wistar rats were allocated into four groups (n = 10): CTRL, Vilda, BPH, and BPH + Vilda groups. Our results revealed that vildagliptin treatment considerably lessened the prostate weight, prostate index, serum levels of prostate-specific antigen, 5α-reductase activity, and DHT levels compared to the testosterone group. Furthermore, vildagliptin treatment inhibited the expression of HMGB1, PI3K/Akt/NF-κB, and TNF-α signaling pathways in the prostate tissue of diseased rats. Additionally, vildagliptin treatment increased the expression of Nrf-2 and HO-1, reduced GSH levels, and lowered MDA levels. Besides, vildagliptin noticeably scaled up the level of cleaved caspase-3 enzyme and, conversely, the protein expression of proliferating cell nuclear antigen (PCNA). Correspondingly, vildagliptin counteracts testosterone-induced histological irregularities in rats' prostates. These findings suggest that vildagliptin may be a potential prophylactic approach to avoid BPH.

Abstract
PURPOSE To evaluate whether bladder wall thickness (BWT) measured by CT can be used to predict bladder outlet obstruction in men with low urinary tract symptoms (LUTS). METHODS From 2015 to 2018, a total of 120 men with lower urinary tract symptoms who underwent both urodynamic studies and CT tests of the lower abdomen or pelvis were involved. Bladder wall thickness values were measured by CT scanning. RESULTS Based on the urodynamic studies, 120 men were categorized into two groups, including 70/120 men (58.3%) in the bladder outlet obstruction (BOO) group and 50/120 men (41.7%) in the non-BOO group. The mean BWT was thicker in the BOO group than in the non-BOO group (3.87 vs. 2.75 mm, p < 0.001). The mean maximum bladder capacity (MBC) was lower in the BOO group than in the non-BOO group (263.42 vs. 308.96 ml, p < 0.001). The mean detrusor pressure at maximum urinary flow rate (PdetQmax) was higher in the patients in the BOO group than in those in the non-BOO group (102.28 vs. 49.25 cmH2O, p < 0.001). The ROC curve showed that BWT was a good predictor with an AUC of 0.855 (95% CI 0.785-0.924, p < 0.001). At the cutoff value of 3.20 mm, the predictive sensitivity of BWT for BOO was 72.9%, and the specificity was 90%. CONCLUSION Increased bladder wall thickness was correlated with bladder outlet obstruction in men with LUTS. Bladder wall thickness measured by CT scans may be a noninvasive parameter to predict bladder outlet obstruction in men with LUTS.

Abstract
PURPOSE To evaluate the effect of urinary retention (UR) on holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms. MATERIALS AND METHODS A retrospective analysis of a prospective cohort of patients who underwent HoLEP between January 2010 and December 2016 was performed. The perioperative factors, including the International Prostate Symptom Score, Overactive Bladder Symptom Score, prostate-specific antigen, urodynamic study results, uroflowmetry results, transrectal ultrasound prostate volume, operative time, morcellation time, enucleation weight, and complications, were evaluated. Postoperative evaluation was performed at 2, 3, and 6 months. RESULTS Overall, 903 patients were identified. The mean age and follow-up were 68.3 years and 6 months, respectively. Among the patients, 135 (15.0%) patients had a history of acute UR (AUR), and 36 patients (4.0%) had chronic UR (CUR). The mean detrusor pressures at maximum flow were 64.4, 74.3, and 77.7 cmH2O (p<0.001). The mean maximum flow rates (Qmax) were 7.6, 6.6, and 4.8 mL/s (p<0.001). Additionally, the mean bladder outlet obstruction indices were 49.5, 61.1, and 69.4 (p<0.001). The postoperative Qmax improved in all three groups. The mean postvoid residual volumes (PVRs) were 55, 75, and 333 mL preoperatively; 20, 29, and 66 mL at 2 weeks; 16, 23, and 45 mL at 3 months; and 15, 22, and 52 mL at 6 months (p<0.001). CONCLUSIONS Voiding symptoms, PVR, and Qmax of BPH patients with preoperative AUR and CUR significantly improved after Ho-LEP, similar to those without preoperative UR.

Abstract
PURPOSE Benign prostatic hyperplasia (BPH) is a urogenital disorder that affects approximately 85% of males who are over 50 years of age. Hydrocotyle ramiflora (HR), belonging to Apiaceae family, is used to treat urinary system diseases such as urine retention in traditional Chinese herbal medicine. In this study, we evaluated the effects of HR in the BPH animal model. METHODS We induced BPH in rats via subcutaneous (sc) injections of testosterone propionate (TP, 3 mg/kg). Rats were also administered HR (150 mg/kg), finasteride (10 mg/kg), or vehicle via oral gavage. After induction, prostate glands were collected, weighed, and processed for further analysis, including histopathological examination and immunohistochemistry. In addition, the mRNA expression of inflammatory cytokines in prostatic tissues was determined by quantitative real-time PCR (qRT-PCR). The protein expression of pro-apoptotic markers was examined using western blotting. RESULTS HR treatment significantly reduced the prostate weight, epithelial thickness, and proliferating cell nuclear antigen (PCNA) expression, with the levels of cleaved caspase-3 and Bcl-2-associated X (Bax) protein considerably increased compared to BPH group. HR also decreased inflammatory cell infiltration and pro-inflammatory cytokine levels compared with BPH group. Furthermore, the expression of phosphor-nuclear factor-κB (NF-κB), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS) were reduced by HR treatment. CONCLUSION These results indicate that HR suppresses the development of BPH associated with anti-proliferative, pro-apoptotic, and anti-inflammatory effects, suggesting it is a potential alternative therapeutic agent for BPH.

Abstract
With the dogma of sterile urine no longer held as truth, numerous studies have implicated distinct changes in microbial diversity and composition to diseased subgroups in both benign and malignant urological diseases, ranging from overactive bladder to bladder and prostate cancer. Further facilitated by novel and effective techniques of urine culture and sequencing, analysis of the genitourinary microbiome holds high potential to identify biomarkers for disease and prognosis. However, the low biomass of samples included in microbiome studies of the urinary tract challenge researchers to draw definitive conclusions, confounded by technical and procedural considerations that must be addressed. Lack of samples and adequate true negative controls can lead to overestimation of microbial influence with clinical relevance. As such, results from currently available studies and assessment of their limitations required a thorough understanding. The purpose of this narrative review was to summarize notable microbiome studies in the field of urology with a focus on significant findings and limitations of study design. Methodological considerations in future research are also discussed.

Abstract
Benign prostatic hyperplasia (BPH) is a condition that primarily affects men between the fourth and seventh decades of life, occurring due to enlargement of the prostate which subsequently causes compression of the prostatic urethra causing chronic obstruction of the urinary outflow tract. BPH can cause significant quality-of-life issues such as urinary hesitancy, intermittency, decreased urinary stream, a sensation of incomplete emptying, dysuria, urinary retention, hematuria, and nocturia. Several medical and surgical treatment modalities are available for the treatment of lower urinary tract symptoms and other BPH-related sequela; however, increasingly prostate artery embolization is being utilized in this patient population. Technical demands for this procedure in this population can be significant. This article describes the optimal techniques, tricks, and advanced imaging techniques that can be used to achieve desired technical outcomes.

Abstract
Abstract
Objectives
Free DNA is used as a cancer biomarker due to its low cost, high applicability, and fast, reliable results compared to invasive methods. This study aimed to evaluate the quantification of plasma-free DNA after long-term storage conditions and perform qualification through Single Nucleotide Polymorphism (SNP) screening based on this DNA.
Methods
Plasma-free DNA samples were quickly isolated from the peripheral blood of both the Benign Prostatic Hyperplasia (BPH) and control group participants and then maintained at −80 °C for four years. Upon thawing, first, free DNA was purified and fluorometric measurements were taken to determine the amount of DNA. Subsequently, the rs6983267, rs12628, and rs1799939 SNPs were screened in the CCAT2, HRAS, and RET genes, respectively.
Results
Significant results were obtained from the fluorometric measurements in terms of single-stranded DNA (ssDNA) (p<0.001). However, there was no significant difference in SNPs rs6983267, rs12628, and rs1799939 in the BPH group compared to the healthy individuals.
Conclusions
The data show that fluorometric ssDNA measurements are suitable for quantifying free DNA. The fact that SNP screening can be done successfully in both healthy people and BPH patients suggests that plasma-free DNA can be stored in the laboratory under appropriate conditions.

Impact of Surgery for Benign Prostatic Hyperplasia on Sexual Function: A Systematic Review and Meta-analysis of Erectile Function and Ejaculatory Function. Eur Urol Focus 2022; 8:1711-1732. [PMID: 35803852 DOI: 10.1016/j.euf.2022.06.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 06/17/2022] [Indexed: 01/25/2023]
Abstract
CONTEXT Several sexual side effects, including erectile, ejaculatory, and orgasmic dysfunction, were reported with the majority of surgical procedures for benign prostatic obstruction (BPO). OBJECTIVE To systematically review current evidence regarding the impact of benign prostatic hyperplasia (BPH) surgery on sexual function. EVIDENCE ACQUISITION A comprehensive bibliographic search on the MEDLINE, Cochrane Library, Embase, Web of Science, and Google Scholar databases was conducted in July 2021. The population, intervention, comparator, and outcome (PICO) model was used to define study eligibility. Studies were Included if they assessed patients with BPO and related lower urinary tract symptoms (P) undergoing BPH surgery (I) with or without a comparison between surgical treatments (C) evaluating the impact on sexual function (O). Retrospective and prospective primary studies were included. A pooled analysis was conducted on studies including the postoperative assessment of International Index of Erectile Function (IIEF)-5, Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD; Function and/or Bother), or retrograde ejaculation (RE) rate (PROSPERO database ID: CRD42020177907). EVIDENCE SYNTHESIS A total of 151 studies investigating 20 531 patients were included. Forty-eight randomized controlled trials evaluating 5045 individuals were eligible for the meta-analysis. In most studies (122, 80.8%), only erectile and/or ejaculatory function was evaluated. A substantial number of articles (67, 44.4%) also used nonvalidated tools to evaluate erectile and/or ejaculatory function. The pooled analysis showed no statistically significant changes in IIEF-5 score compared with baseline for the transurethral resection of the prostate (TURP; weighted mean difference [WMD] 0.76 pts; 95% confidence interval [CI] -0.1, 1.62; p = 0.08), laser procedure (WMD 0.33 pts; 95% CI -0.1, 0.77; p = 0.13), and minimally invasive treatment (WMD -1.37 pts; 95% CI -3.19, 0.44; p = 0.14) groups. A statistically significantly higher rate of RE was found after TURP (risk ratio [RR] 13.31; 95% CI 8.37, 21.17; p < 0.00001), other electrosurgical procedures (RR 34.77; 95% CI 10.58, 127.82; p < 0.00001), and the entire laser group (RR 17.37; 95% CI 5.93, 50.81; p < 0.00001). No statistically significant increase in RE rate was described after most of the minimally invasive procedures (p > 0.05). The pooled analysis of MSHQ-EjD scores was possible only for prostatic urethral lift, showing no statistically significant difference between baseline and post-treatment MSHQ-EjD Function scores (WMD -0.80 pts; 95% CI -2.41, 0.81; p = 0.33), but postoperative MSHQ-EjD Bother scores were significantly higher (WMD 0.76 pts; 95% CI 0.22, 1.30; p = 0.006). CONCLUSIONS Erectile function appears to be unaffected by most surgical procedures for BPO. RE is a very common adverse event of BPH surgery, although emerging minimally invasive surgical procedures could be associated with a lower risk. PATIENT SUMMARY Benign prostatic hyperplasia surgery can have an impact on sexual function, mainly involving ejaculatory function.

A constrained mixture-micturition-growth (CMMG) model of the urinary bladder: Application to partial bladder outlet obstruction (BOO). J Mech Behav Biomed Mater 2022; 134:105337. [PMID: 35863296 PMCID: PMC9835014 DOI: 10.1016/j.jmbbm.2022.105337] [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] [Received: 09/15/2021] [Revised: 04/13/2022] [Accepted: 06/24/2022] [Indexed: 01/14/2023]
Abstract
We present a constrained mixture-micturition-growth (CMMG) model for the bladder. It simulates bladder mechanics, voiding function (micturition) and tissue adaptations in response to altered biomechanical conditions. The CMMG model is calibrated with both in vivo and in vitro data from healthy male rat urinary bladders (cystometry, bioimaging of wall structure, mechanical testing) and applied to simulate the growth and remodeling (G&R) response to partial bladder outlet obstruction (BOO). The bladder wall is represented as a multi-layered, anisotropic, nonlinear constrained mixture. A short time scale micturition component of the CMMG model accounts for the active and passive mechanics of voiding. Over a second, longer time scale, G&R algorithms for the evolution of both cellular and extracellular constituents act to maintain/restore bladder (homeostatic) functionality. The CMMG model is applied to a spherical membrane model of the BOO bladder utilizing temporal data from an experimental male rodent model to parameterize and then verify the model. Consistent with the experimental studies of BOO, the model predicts: an initial loss of voiding capacity followed by hypertrophy of SMC to restore voiding function; bladder enlargement; collagen remodeling to maintain its role as a protective sheath; and increased voiding duration with lower average flow rate. This CMMG model enables a mechanistic approach for investigating the bladder's structure-function relationship and its adaption in pathological conditions. While the approach is illustrated with a conceptual spherical bladder model, it provides the basis for application of the CMMG model to anatomical geometries. Such a mechanistic approach has promise as an in silico tool for the rational development of new surgical and pharmacological treatments for bladder diseases such as BOO.

Efficacy and safety of adrenergic alpha-1 receptor antagonists in older adults: a systematic review and meta-analysis supporting the development of recommendations to reduce potentially inappropriate prescribing. BMC Geriatr 2022; 22:771. [PMID: 36171560 PMCID: PMC9516834 DOI: 10.1186/s12877-022-03415-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Accepted: 08/26/2022] [Indexed: 11/25/2022] Open
Abstract
Background Adrenergic alpha-1 receptor antagonists (alpha-1 antagonists) are frequently used medications in the management of lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) and in the management of therapy-resistant arterial hypertension, two conditions frequently found in older adults. This systematic review aims at presenting a complete overview of evidence over the benefits and risks of alpha-1 antagonist treatment in people ≥ 65 years, and at deriving recommendations for a safe application of alpha-1 antagonists in older adults from the evidence found. Methods A comprehensive literature search was performed (last update March 25th 2022) including multiple databases (Medline/Pubmed, Embase, the Cochrane Library) and using the PICOS framework to define search terms. The selection of the studies was done by two independent reviewers in a two-step approach, followed by a systematic data extraction. Quality appraisal was performed for each study included using standardised appraisal tools. The studies retrieved and additional literature were used for the development of recommendations, which were rated for strength and quality according to the GRADE methodology. Results Eighteen studies were included: 3 meta-analyses, 6 randomised controlled trials and 9 observational trials. Doxazosin in the management of arterial hypertension was associated with a higher risk of cardiovascular disease, particularly heart failure, than chlorthalidone. Regarding treatment of LUTS suggestive of BPH, alpha-1 antagonists appeared to be effective in the relief of urinary symptoms and improvement of quality of life. They seemed to be less effective in preventing disease progression. Analyses of the risk profile indicated an increase in vasodilation related adverse events and sexual adverse events for some agents. The risk of falls and fractures as well as the effects of long-term treatment remained unclear. All meta-analyses and 5 out of 6 interventional studies were downgraded in the quality appraisal. 7 out of 9 observational studies were of good quality. Conclusions It cannot be recommended to use doxazosin as first-line antihypertensive agent neither in older adults nor in younger patients. In the management of BPH alpha-1 antagonists promise to effectively relieve urinary symptoms with uncertainty regarding their efficacy in preventing long-term progression events.

Cordycepin Attenuates Testosterone-Induced Benign Prostatic Hyperplasia in Rats via Modulation of AMPK and AKT Activation. Pharmaceutics 2022; 14:pharmaceutics14081652. [PMID: 36015278 PMCID: PMC9415290 DOI: 10.3390/pharmaceutics14081652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Revised: 08/02/2022] [Accepted: 08/05/2022] [Indexed: 12/01/2022] Open
Abstract
Benign prostatic hyperplasia (BPH) is a disease that commonly affects elderly men. Cordycepin is an adenosine analog with a wide range of pharmacological activities including antiproliferative and prostatic smooth muscle relaxant effects. This study was designed to assess the actions of cordycepin in testosterone-induced BPH in rats. Animals were divided into six treatment groups: control, cordycepin-alone (10 mg/kg), testosterone-alone (3 mg/kg), cordycepin (5 mg/kg) + testosterone, cordycepin (10 mg/kg) + testosterone, and finasteride (0.5 mg/kg) + testosterone. Treatments were continued daily, 5 days a week, for 4 weeks. Cordycepin significantly prevented the increase in prostate weight and prostate index induced by testosterone. This was confirmed by histopathological examinations. Cordycepin antiproliferative activity was further defined by its ability to inhibit cyclin-D1 and proliferating cell nuclear antigen (PCNA) expression. In addition, cordycepin exhibited significant antioxidant properties as proven by the prevention of lipid peroxidation, reduced glutathione diminution, and superoxide dismutase exhaustion. This was paralleled by anti-inflammatory activity as shown by the inhibition of interleukin-6, tumor necrosis factor-α, and nuclear factor-κB expression in prostatic tissues. It also enhanced apoptosis as demonstrated by its ability to enhance and inhibit mRNA expression of Bax and Bcl2, respectively. Western blot analysis indicated that cordycepin augmented phospho-AMP-activated protein kinase (p-AMPK) and inhibited p-AKT expression. Collectively, cordycepin has the ability to prevent testosterone-induced BPH in rats. This is mediated, at least partially, by its antiproliferative, antioxidant, anti-inflammatory, and pro-apoptotic actions in addition to its modulation of AMPK and AKT activation.

Abstract
Benign prostate hyperplasia (BPH) refers to the nonmalignant enlargement of the transition zone of the prostate gland. While holmium laser enucleation of the prostate and open simple prostatectomy are effective in the management of patients with large prostates, they have some limitations. Thus, this study aimed to analyze the efficacy and safety of the sandwich method of bipolar transurethral resection of the prostate (B-TURP) and GreenLight photoselective vaporization of the prostate (GLPVP) in patients with large prostates. Patients diagnosed with BPH who underwent the sandwich method with B-TURP and GLPVP from 2015 to 2020 were included. Efficacy analyses included the change in the uroflowmetry results in both group A (prostate volume < 80 g) and group B (prostate volume ≥ 80 g), and complication analyses included perioperative complications, early postoperative complications at three months and late postoperative complications at 12 months. The cohort comprised 188 and 44 patients in groups A and B, respectively. The prostate volume of groups A and B were 50.83 ± 14.14 g and 102.03 ± 19.36 g (p < 0.001), respectively. The peak (Qmax) and average (Qavg) flow rates were comparable between the two groups. The only significant difference noted was in the postoperative post-void residual (PVR) urine. Improvement was seen in all the variables including the Qmax, Qavg and PVR urine in each group. No patient experienced perioperative complications. Analysis of the overall one-year complication rate showed no significant difference between the two groups. The sandwich method of B-TURP and GLPVP may be feasible for the management of patients with large prostate.

Abstract
Benign prostatic hyperplasia, urolithiasis, recurrent urinary tract infections, and chronic prostatitis are diseases that are commonly diagnosed worldwide. Carotenoids, including lycopene, are widely available in fruits and vegetables, and it is postulated that they can be used in the prevention and treatment of benign urological conditions. The aim of this review is to familiarize doctors and their patients with the current knowledge on carotenoids and their conversion products in selected urological diseases. Most of the experimental and clinical trials show a moderate effect of lycopene and vitamin A on studied parameters. Lycopene was shown to improve the IPSS score in BPH patients, and alleviate symptoms in those with chronic prostatitis. Intake of Vitamin A was associated with decrease of urinary tract reinfection rates. In studied rat models retinol also decreased urolithiasis formation. Although the results of the cited studies are generally promising, it is evident that more detailed and extensive research must be done in this field of medicine.

Abstract
Acute urinary retention is a common clinical presentation in emergency departments in the UK and is responsible for over 30 000 hospital admissions annually. Awareness of the latest advice and guidelines regarding its presentation, investigation and management is paramount to improve patient outcomes and reduce morbidity. Immediate management of acute urinary retention relies on timely bladder decompression by catheterisation. Knowledge of the routes and types of catheterisation, including the associated risks, complications and contraindications, is essential to allow rapid and early intervention, thus preventing further complications. Differences in the presentation of patients with acute urinary retention reflect varying aetiologies, the knowledge of which determines long-term management and prognosis.

Abstract
OBJECTIVES To describe and analyze the learning curve (LC) of aquablation for the treatment of benign prostatic obstruction and determine the number of cases needed to achieve acceptable surgical safety, efficiency, and efficacy. METHODS A retrospective analysis of prospectively maintained aquablation databases from France, Lebanon, and Spain was conducted. The combined LC of three surgeons was defined by trifecta and pentafecta outcomes. Trifecta reflected efficiency and safety: operative time < 60 min, hemoglobin reduction ≤ 2 mg/dL, and no 90 day Clavien-Dindo grade ≥ 2 complications. Pentafecta reflected effectiveness: percent reduction in International Prostate Symptom Score (IPSS) and ejaculation preservation. The combined LC was plotted using a moving average with polynomial fitting. RESULTS The cohort included 175 consecutive patients. Median (IQR) prostate volume was 70 (50-91) cc, and baseline IPSS was 23 (18-27). The achievement of trifecta exceeded 50% after 4 cases, and 70% after 50 cases. Pentafecta achievement exceeded 50% after 38 cases. Logistic regression showed significant improvement in hemoglobin reduction and ejaculation preservation. Grade ≥ 2 complication was not affected by experience, and neither was 3 month %IPSS reduction as 94% of patients showed ≥ 50% symptoms' improvement. CONCLUSION Aquablation is associated with a quick learning curve for the defined trifecta and pentafecta outcomes. It provided effective LUTS relief and low complication rates independent of surgeon experience. Hemoglobin drop and ejaculatory function preservation were the two factors influenced by the surgeons' LC. Training to reduce operative time, standardization of hemostasis techniques, and early assistance to improve veru-protection zone planning are keys to quicker learning.

Lectins applied to diagnosis and treatment of prostate cancer and benign hyperplasia: A review. Int J Biol Macromol 2021; 190:543-553. [PMID: 34508719 DOI: 10.1016/j.ijbiomac.2021.09.011] [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: 06/19/2021] [Accepted: 09/02/2021] [Indexed: 11/20/2022]
Abstract
Environmental factors, as well as genetic factors, contribute to the increase in prostate cancer cases (PCa), the second leading cause of cancer death in men. This fact calls for the development of more reliable, quick and low-cost early detection tests to distinguish between malignant and benign cases. Abnormal cell glycosylation pattern is a promising PCa marker for this purpose. Proteins, such as lectins can decode the information contained in the glycosylation patterns. Several studies have reported on applications of plant lectins as diagnostic tools for PCa considering the ability to differentiate it from benign cases. In addition, they can be used to detect, separate and differentiate the glycosylation patterns of cells or proteins present in serum, urine and semen. Herein, we present an overview of these studies, showing the lectins that map glycans differentially expressed in PCa, as well as benign hyperplasia (BPH). We further review their applications in biosensors, histochemical tests, immunoassays, chromatography, arrays and, finally, their therapeutic potential. This is the first study to review vegetable lectins applied specifically to PCa.

Abstract
Intraurethral inoculation of mice with uropathogenic Escherichia coli (CP1) results in prostate inflammation, fibrosis, and urinary dysfunction, recapitulating some but not all of the pathognomonic clinical features associated with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). In both patients with LUTS and CP1-infected mice, we observed increased numbers and activation of mast cells and elevated levels of prostate fibrosis. Therapeutic inhibition of mast cells using a combination of a mast cell stabilizer, cromolyn sodium, and the histamine 1 receptor antagonist cetirizine di-hydrochloride in the mouse model resulted in reduced mast cell activation in the prostate and significant alleviation of urinary dysfunction. Treated mice showed reduced prostate fibrosis, less infiltration of immune cells, and decreased inflammation. In addition, as opposed to symptomatic CP1-infected mice, treated mice showed reduced myosin light chain-2 phosphorylation, a marker of prostate smooth muscle contraction. These results show that mast cells play a critical role in the pathophysiology of urinary dysfunction and may be an important therapeutic target for men with BPH/LUTS.NEW & NOTEWORTHY LUTS-associated benign prostatic hyperplasia is derived from a combination of immune activation, extracellular matrix remodeling, hyperplasia, and smooth muscle cell contraction in prostates of men. Using a mouse model, we describe the importance of mast cells in regulating these multiple facets involved in the pathophysiology of LUTS. Mast cell inhibition alleviates both pathology and urinary dysfunction in this model, suggesting the potential for mast cell inhibition as a therapeutic that prevents and reverses pathology and associated symptomology.

Abstract
Context: Intravesical prostatic protrusion (IPP) is a potential candidate for the initial evaluation of patients with lower urinary tract symptoms (LUTS). Intravesical prostatic protrusion is also known to predict the outcome of trials without a catheter and medical treatment outcomes and to determine bladder outlet obstructions. Objectives: This study aimed to determine whether IPP influences the residual LUTS after surgery in patients with benign prostate hyperplasia who have undergone prostate surgery. Evidence Acquisition: An online database search was conducted regarding the prognosis of postoperative benign prostate hyperplasia patients with intravesical prostatic protrusions. The selected databases comprised PubMed, ScienceDirect, EBSCO, and Cochrane Library. Randomized controlled trial, cohort, or case control studies that were written in English or Bahasa and published up until November 2020 were included. We reviewed postoperative outcomes, including subjective symptoms, based on the International Prostate Symptom Score and objective signs, such as Qmax and post voiding residue. Results: Our initial database search yielded 143 papers. After exclusion from abstract screening, seven papers were considered for full-text analysis. Five of these studies showed higher preoperative intravesical prostatic protrusion within successful postoperative outcomes. Some studies showed that patients with significant intravesical prostatic protrusions had more significant International Prostate Symptom Score decrements. However, two studies demonstrated that intravesical prostatic protrusion was not a significant prognostic factor. Conclusions: Most studies suggested that intravesical prostatic protrusion can predict better post-surgery lower urinary tract symptom outcomes. Further research using information about the risk of bias in ultrasound examination and more homogeneous surgical techniques and considering the duration of patients’ illness before they receive surgical management is needed.

Abstract
Benign prostatic hyperplasia (BPH) is one of the most common chronic diseases in men over the age of 50. Clinical studies have suggested that chronic inflammation is associated with BPH pathoprogression. Berberine (BB) is a natural compound found in Berberis vulgaris, Coptis chinensis and Phellodendron amurense. Although several studies have documented that BB may be effective for inflammation, the effects of the oral administration of BB on BPH are not fully understood. The effects of BB on chronic prostatic inflammation were evaluated in a testosterone-induced BPH animal model. Orally administered BB alleviated the pathological alterations induced by BPH and significantly suppressed the expression of inflammatory markers while enhancing the expression of antioxidant factors. Furthermore, BB regulated the activation of macrophages via NF-κB signaling pathway inhibition in the BPH rat model. The effects and underlying signaling pathway of BB in RWPE-1 cells exposed to macrophage conditioned medium (CM) were also demonstrated in vitro. While CM stimulation induced prostatic cell proliferation and upregulated the expression of inflammatory factors, BB exerted anti-proliferation and anti-inflammatory effects in RWPE-1 cells. These findings propose that BB suppresses androgen-dependent BPH development by targeting NF-κB-mediated pro-inflammatory signaling.

Abstract
Complicated urinary tract infection (UTI) is a symptomatic urinary infection accompanied by functional or structural abnormalities of the genitourinary tract. Benign prostatic hyperplasia (BPH) is a major cause of lower urinary tract obstruction in male patients, and bladder outlet obstruction (BOO) secondary to BPH can lead to UTIs in men. However, no evidence has clearly shown that UTI in the aging male population is associated with either post-void residual urine or BOO. Screening for the presence of bacteriuria is recommended prior to any procedure manipulating the urinary tract, and imaging studies of the upper urinary tract are recommended to identify underlying abnormalities. Recurrent or persistent UTI in men with BPH is an indication for surgical treatment. Asymptomatic bacteriuria should be screened for and treated before transurethral resection of the prostate (TURP). In addition, antibiotic prophylaxis reduced the risk of UTI in patients undergoing TURP. The choice of specific antimicrobial for prophylaxis should be based on local pathogen prevalence and individual antibiotic susceptibility. Patients with severe systemic infections require hospitalization, and empirical therapy should include an intravenous antimicrobial regimen. Further prospective studies are needed to refine the treatment process for complicated UTI in patients diagnosed with BPH.

Abstract
Objective Bleeding is one of the most common complications of transurethral resection of the prostate (TURP). Several previous studies reported that administering dutasteride before surgery could reduce perioperative bleeding. We aimed to evaluate the efficacy of preoperative dutasteride treatment in benign prostatic hyperplasia patients undergoing TURP by performing a meta-analysis of relevant randomized controlled trials (RCTs). Methods A comprehensive literature search was performed through the electronic databases including Medline, Cochrane Library, Google Scholar, and ClinicalTrial.gov in October 2020. RCTs evaluating the role of dutasteride for TURP were screened using the eligibility criteria and the quality of RCTs was assessed using the Cochrane Risk of Bias Tool. The heterogeneity was assessed using I2 statistic. The measured outcomes were hemoglobin (Hb) levels, perioperative blood loss, blood transfusion, microvessel density (MVD), and operation time. Data were pooled as mean difference (MD) and odds ratio (OR). Results A total of 11 RCTs consisting of 627 samples from the treatment group and 615 samples from the placebo group were analyzed. Patients that received dutasteride had less reduction in Hb levels (MD −1.10, 95% confidence interval [CI] −1.39 to −0.81, p<0.00001). Dutasteride also significantly reduced the operation time (MD −1.79, 95% CI −2.97 to −0.61, p=0.003) and transfusion rate after surgery (OR 0.34, 95% CI 0.15 to 0.77, p=0.009) compared to the control group. However, the MVD (MD −3.60, 95% CI −8.04 to 0.84, p=0.11) and perioperative blood loss in dutasteride administration for less than 4 weeks (MD 46.90, 95% CI −144.60 to 238.41, p=0.63) and more than 4 weeks (MD −190.13, 95% CI −378.05 to −2.21, p=0.05) differences were insignificant. Conclusion Preoperative administration of dutasteride is able to reduce bleeding during TURP, as indicated by less reduction in Hb level, lower transfusion rate, and less operation time.

Abstract
Objective The aim of the present study was to investigate the protective effects and mechanisms of KLK1 on aging-related prostate alterations and search clues about the application of KLK1 to the treatment of human BPH. Methods Thirty-six rats including 26 male wild-type SD rats and 10 transgenic rats were fed to 3- or 18-month-old and divided into three groups: young WTR (yWTR) as the control (n = 16), aged WTR (aWTR) (n = 10), and aged TGR (aTGR) (n = 10). The prostates of the three groups of rats (10 rats per group) were harvested to evaluate the levels of KLK1 expression, oxidative stress, fibrosis, and involved signaling pathways, such as NO/cGMP, COX-2/PTGIS/cAMP, and TGF-β1/RhoA/ROCK1, via quantitative PCR, Western blot, histological examinations, and ELISA. Moreover, the remaining 6 yWTRs were sacrificed to obtain primary prostate fibroblast and aortic endothelial cells, and a coculture system was built with the cells for the verification of above signaling pathways in vitro. And the direct effects of bradykinin on prostate cells were detected by MTT experiment. Prostate specimens of 47 patients (age from 48 to 92 years) undergoing BPH surgery were collected after approval. Histological examinations and KLK1 IHC were preformed to analyze the relationship between KLK1 expression and age and prostate fibrosis. Results The human KLK1 gene only existed and was expressed in aTGR. The prostate of young rats expressed more KLK1 than the aged and the expression of KLK1 in prostate decreased with age in humans (r = −0.347, P = 0.018). Compared to the aWTR group, the yWTR and aTGR groups showed milder fibrosis, less oxidative stress, upregulated NO/cGMP, and COX-2/PTGIS/cAMP signaling pathways and inhibited TGF-β1/RhoA/ROCK1 signaling pathway. In the coculture system, KLK1 suppressed TGF-β1-mediated fibroblast-to-myofibroblast transdifferentiation via cleaving LMWK to produce the BK which upregulate eNOS expression and NO production in endothelial cells. BK not only slightly stimulated the proliferation ability of prostatic stromal cells but also upregulated iNOS and inhibited TGF-β1 expression in them. Conclusion KLK1 protects prostate from oxidative stress and fibrosis via amplified NO/cGMP signal in aged rats. The decrease of KLK1 expression with aging is laying the groundwork for the application of KLK1 to the treatment of human BPH. The current experimental data showed that the side effects of KLK1 on the prostate cell were not obvious.

Abstract
Introduction Inflammation and infection are causative factors of benign prostatic hyperplasia (BPH). Urine is not sterile, and urine microbiota identified by DNA sequencing can play an important role in the development of BPH and can influence the severity of lower urinary tract symptoms (LUTS). Materials and methods We collected mid-stream voided urine samples from BPH patients and control participants and stored them in a freezer at − 80 °C. All enrolled participants were requested to provide information about their clinical characteristics and complete the International Prostate Symptom Score (IPSS) questionnaire. Each step of the procedure, including the extraction of the genomic DNA from the urine samples; the amplification by polymerase chain reaction (PCR); PCR product quantification, mixing, and purification; DNA library preparation; and sequencing was performed with quality control (QC) measures. Alpha diversity was indicative of the species complexity within individual urine samples, and beta diversity analysis was used to evaluate the differences among the samples in terms of species complexity. Pearson’s correlation analysis was performed to calculate the relationship between the clinical characteristics of the participants and the microbiota species in the urine samples. Results We enrolled 77 BPH patients and 30 control participants who reported no recent antibiotic usage. Old age, high IPSS and poor quality of life were observed in the participants of the BPH group. No significant differences were observed in the alpha diversity of the samples. In the beta diversity analysis, there was a significant difference between the microbiota in the samples of the BPH and control groups according to ANOSIM statistical analysis. On comparing the groups, the ten bacterial genera present in the samples of the BPH group in descending order of abundance were: Sphingomonas, Bacteroides, Lactobacillus, Streptococcus, Alcaligenes, Prevotella, Ruminococcaceae UCG-014, Escherichia_Shigella, Akkermansia, and Parabacteroides. Spearman’s correlation analysis revealed that urine samples showing the presence of the bacterial genera Haemophilus, Staphylococcus, Dolosigranulum, Listeria, Phascolarctobacterium, Enhydrobacter, Bacillus, [Ruminococcus]torques, Faecalibacterium, and Finegoldia correlated with a high IPSS, and severe storage and voiding symptoms (P < 0.05). Conclusion Our current study shows that dysbiosis of urine microbiota may be related to the development of BPH and the severity of LUTS. Further research targeting specific microbes to identify their role in the development of diseases is necessary and might provide novel diagnostic biomarkers and therapeutic options.

Abstract
BACKGROUND The diagnosis of lower urinary tract symptoms related to suspected bladder outflow obstruction from benign prostate hyperplasia/enlargement in men is increasing. This is leading to high demand on healthcare services; however, there is limited knowledge of differences in pharmacotherapy prescribing for this condition based on geography. OBJECTIVE To investigate potential variation in drug prescribing for suspected bladder outflow obstruction in Scotland, based on analysis of publicly available data, to identify trends and inform future prescribing. STUDY DESIGN A longitudinal register-based data study of prescribing and patient data publicly available from Scottish registries. All information is available as monthly aggregates at the level of single general practices. SETTING AND PARTICIPANTS 903 (97%) general practices in Scotland, over a 50-month period (October 2015 to November 2019). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS We analysed numbers of daily doses of drugs for suspected bladder outflow obstruction prescribed per month using a Bayesian Poisson regression analysis, incorporating random effects to account for spatial and temporal elements. RESULTS Prescriptions for suspected bladder outflow obstruction medications increased during the observation period (overall average rate of change 1.24±0.28, ranging from 0.893 in Orkney to 1.95 in Lanarkshire). While some determinants of health inequality regarding prescribing practices across health boards are consistent with those known from the literature, other inequalities remain unexplained after accounting for practice-specific and patient-specific characteristics such as deprivation and rurality. CONCLUSIONS Inequalities in prescribing for suspected bladder outflow obstruction medications exist in Scotland, partially ascribable to accepted sociodemographic and geographic factors.

Amelioration of testosterone-induced benign prostatic hyperplasia using febuxostat in rats: The role of VEGF/TGFβ and iNOS/COX-2. Eur J Pharmacol 2020; 889:173631.

Abstract
Benign prostatic hyperplasia (BPH) is a common male disorder. Febuxostat is a non-purine, selective inhibitor of xanthine oxidase (XO), which has a strong antioxidant capacity and pleiotropic pharmacological properties. This study's objective was to explore the potential ameliorative effects of febuxostat against testosterone-induced BPH in rats. Febuxostat (10 mg/kg/day, per os [p.o.]) prevented increased prostate index levels, serum levels of prostate-specific antigen (PSA), and testosterone levels compared to animals treated with testosterone alone, when administered for 28 days. Histological examination indicated that febuxostat dramatically ameliorated pathological changes in the prostate architecture compared to the testosterone group. Similarly, febuxostat markedly improved testosterone-induced oxidative stress by inhibiting the increase in lipid peroxide and nitrite content, and by reducing the level of depletion of reduced glutathione (GSH) and superoxide dismutase (SOD) activity, which significantly reduced the prostate content of pro-inflammatory cytokines, including tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6). Furthermore, febuxostat significantly reduced the prostatic content, both in terms of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) messenger ribonucleic acid (mRNA) levels, and of protein levels. Moreover, compared to the testosterone group, febuxostat's beneficial effects prevented the increase in growth factors, comprising vascular endothelial cell growth factor A (VEGF-A) and transforming growth factor beta (TGF-β) protein levels. Its ameliorating effects were equal to those of finasteride, which is the most widely used remedy for BPH. In conclusion, this study provides novel evidence that febuxostat experimentally attenuates testosterone-induced BPH in rats, at least in part by inhibiting iNOS/COX-2 and VEGF/TGF-β pathways.

Abstract
Abstract
Background
The prevalence of benign prostate hyperplasia (BPH) varies among individuals from different races or ethnic groups. South-Kivu province (DR Congo) has several morphologically different ethnic groups. Our aim was to compare prostate volume and assess its possible association with specific anthropometric measurements among major ethnic groups.
Methods
This is a cross-sectional study of male subjects, ≥ 40 year old, enrolled in 10 different sites of South-Kivu allowing both easy access and ethnic diversity. We compared urological features, anthropometric parameters, and body fat composition among 979 subjects who met study criteria: Shi (n: 233), Lega (n: 212), Havu (n: 204), Bembe–Fuliru (n: 172), and minority ethnic groups (n: 158).
Results
Prostate volume was statistically different among ethnic groups. Median (interquartile range) size of prostate gland was significantly larger in Lega: 55 (38–81) cc, and smaller in Havu, 20 (17, 24) cc; p < 0.001. Overall, an enlarged prostate (≥ 30 cc) was documented in 91% of Lega men, in 59% of intermediate class men (Shi, Bembe–Fuliru, others), and in a mere 11% of Havu men. In multivariate analysis, prostate volume was significantly associated with age (p < 0.001), ethnic group (p < 0.001), residence (p: 0.046), and fasting blood glucose (p: 0.001). Conversely, prostate volume was neither associated with anthropometric parameters, nor with body fat composition.
Conclusion
Prostatic size varies widely among men from different ethnic origins in South-Kivu. Different genetic determinants and cellular composition of prostatic gland could represent risk factors that need to be examined in forthcoming studies.

Abstract
In recent years, nanotechnology has revolutionized global healthcare and has been predicted to exert a remarkable effect on clinical medicine. In this context, the clinical use of nanomaterials for cancer diagnosis, fertility preservation, and the management of infertility and other pathologies linked to pubertal development, menopause, sexually transmitted infections, and HIV (human immunodeficiency virus) has substantial promise to fill the existing lacunae in reproductive healthcare. Of late, a number of clinical trials involving the use of nanoparticles for the early detection of reproductive tract infections and cancers, targeted drug delivery, and cellular therapeutics have been conducted. However, most of these trials of nanoengineering are still at a nascent stage, and better synergy between pharmaceutics, chemistry, and cutting-edge molecular sciences is needed for effective translation of these interventions from bench to bedside. To bridge the gap between translational outcome and product development, strategic partnerships with the insight and ability to anticipate challenges, as well as an in-depth understanding of the molecular pathways involved, are highly essential. Such amalgamations would overcome the regulatory gauntlet and technical hurdles, thereby facilitating the effective clinical translation of these nano-based tools and technologies. The present review comprehensively focuses on emerging applications of nanotechnology, which holds enormous promise for improved therapeutics and early diagnosis of various human reproductive tract diseases and conditions.

Systematic Review and Meta-analysis Comparing Prostatic Artery Embolization to Gold-Standard Transurethral Resection of the Prostate for Benign Prostatic Hyperplasia. Cardiovasc Intervent Radiol 2020; 44:183-193. [PMID: 33078236 DOI: 10.1007/s00270-020-02657-5] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2020] [Accepted: 09/18/2020] [Indexed: 12/13/2022]
Abstract
PURPOSE To report a comparative systematic review and meta-analysis of prostatic artery embolization (PAE) and transurethral resection of the prostate (TURP) for the management of benign prostatic hyperplasia (BPH). MATERIALS AND METHODS A multi-database search for relevant literature was conducted on 15 July 2020 to include studies published on or before that date. Search terms used were: (prostate embolization OR prostatic embolization OR prostate embolization OR prostatic embolization) AND (prostatic hyperplasia OR prostatic obstruction). Risk of bias was assessed using Cochrane Collaboration and ROBINS-I criteria. Random-effects meta-analysis was performed using RevMan 5.3. RESULTS Six studies with 598 patients were included. TURP was associated with significantly more improvement in maximum urinary flow rate (Qmax) (mean difference = 5.02 mL/s; 95% CI [2.66,7.38]; p < 0.0001; I2 = 89%), prostate volume (mean difference = 15.59 mL; 95% CI [7.93,23.25]; p < 0.00001; I2 = 88%), and prostate-specific antigen (PSA) (mean difference = 1.02 ng/mL; 95% CI [0.14,1.89]; p = 0.02; I2 = 71%) compared to PAE. No significant difference between PAE and TURP was observed for changes in International Prostate Symptoms Score (IPSS), IPSS quality of life (IPSS-QoL), International Index of Erectile Function (IIEF-5), and post-void residual (PVR). PAE was associated with fewer adverse events (AEs) (39.0% vs. 77.7%; p < 0.00001) and shorter hospitalization times (mean difference = -1.94 days; p < 0.00001), but longer procedural times (mean difference = 51.43 min; p = 0.004). CONCLUSION Subjective symptom improvement was equivalent between TURP and PAE. While TURP demonstrated larger improvements for some objective parameters, PAE was associated with fewer AEs and shorter hospitalization times. LEVEL OF EVIDENCE II Level 2a, Systematic Review.

Voiding Dysfunction in Old Male Rats Associated With Enlarged Prostate and Irregular Afferent-Triggered Reflex Responses. Int Neurourol J 2020; 24:258-269. [PMID: 33017896 PMCID: PMC7538283 DOI: 10.5213/inj.2040114.057] [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: 04/16/2020] [Accepted: 05/24/2020] [Indexed: 11/08/2022] Open
Abstract
Purpose This study was conducted to evaluate the hypothesis that an enlarged prostate in old rats may lead to complications associated with voiding dysfunction involving ionotropic P2X2/3-type purinergic receptors Methods Intact animals were divided into male young (MYR; 8–10 weeks old) and male old (MOR; 20 months old) rats. The animals underwent simultaneous detrusor electromyography (EMG) and suprapubic cystometry (CMG) under urethane anesthesia. Immunofluorescence techniques were used to evaluate prostatic autonomic innervation and P2X3R expression in bladder urothelial cells. The functional role of P2X3R was characterized by intramuscular application of AF-353, a selective P2X2/3R antagonist. Results The prostate index significantly increased in MOR, suggestive of an enlarged prostate affecting micturition patterns. Significant EMG and CMG differences were found between MYR and MOR. Higher immunoreactivity for P2X2/3R in the urothelial layer and for prostatic neurofilaments was seen in MOR. Systemic inhibition of P2X2/3R had minimal effects on MYR responsiveness, but improved voiding function in MOR with a marked decrease of intravesical pressure and bladder contractile responses. Conclusions The data support the hypothesis that an enlarged prostate in MOR may contribute to voiding dysfunction involving activation of P2X2/3R, which enhances a prostate-bladder reflex. This reflex may increase bladder afferent transmission and activation of increased prostate innervation, leading to voiding dysfunction.

Abstract
Benign prostatic hyperplasia (BPH), a common cause of lower urinary tract symptoms in the elderly male population, has conventionally treated by transurethral resection of the prostate (TURP). During recent years, newer minimally invasive therapies (MITs) have entered the playing field and challenged TURP with their convenience, lack of sexual side effects, and overall safety. The present paper provides an update on the more heavily studied and most recent MITs, analyzing their mechanism of action, tolerability, and efficacy in clinical practice. Particularly, robust clinical data have propelled UroLift and Rezuum to the forefront in the armamentarium of minimally invasive BPH treatment. Newer mechanical therapies such as the temporary implantable nitinol device, ClearRing, ZenFlow Spring, and Butterfly are appealing options as they forego cutting, ablation, heating, or removing prostatic tissue. It is obvious that there is wide variation in the degree of clinical readiness of each modality and only time and long-term, multicenter studies will decide which of these therapies are accepted by the patient and urologist.

Abstract
Benign prostate hyperplasia (BPH) is a common disease in old-age males, accounting for approximately 77% of morbidity within the age range of 40 to 70 years. It has been shown that morbidity increases with social graying. Quisqualis indica linn (QI) has been used to treat inflammation, stomach pain, and digestion problems. In this study, we evaluated the symptom-regulating effects of QI extract on a testosterone-induced BPH rat model. After inducing BPH in rats using testosterone propionate (TP) injection, we assessed basal intraurethral pressure (IUP) and increments of IUP elicited by electrical field stimulation (5 V, 5, 10, or 20 Hz) or phenylephrine (Phe) (0.01, 0.03, 0.1 mg/kg IV). To induce BPH, 8-week-old rats were subjected to a daily subcutaneous TP (3 mg/kg) injection for 4 weeks. Finasteride (Fina) (10 mg/kg PO) was administered to the rats in the first treatment, while QI (150 mg/kg PO) was administered to those in the second group. Blood pressure was measured together with IUP, after which low urinary tract (LUT), ventral prostate (VP), testicle, and corpus spongiosum were isolated and weighed. Basal IUPs for the Fina- and QI-treated groups were 87.6 and 86.8%, respectively. LUT and VP organ weights in the QI group were lower than those in the Fina group. However, the QI group showed significantly reduced electrical stimulated or Phe-induced IUP increment compared to the Fina and BPH groups. These results proved that QI can be beneficial for BPH symptoms by inhibiting 5α-reductase and consequently decreasing prostate and releasing urinary pressure.

Abstract
Research has been consistently showing the role of zinc (Zn) in prostate function. In this article, we review the current literature on the anatomy and main functions of the prostate, highlighting the role of zinc. In particular, we will review the etiology of benign prostate enlargement (BPH), its prevalence in men over 50, the likelihood of BPH becoming prostate cancer (PCa), and explain the relationship of zinc and apoptosis in the prostate cells and the implications for BPH and PCa. We present a model that explains how endogenous factors provoke excretion of zinc or limit zinc absorption, and how exogenous factors like nutrition and drugs regularly used in men over 50 can significantly decrease zinc status and thereby increase the risk of BPH. Finally, we explain how Zn amino acid (AA) complexes may be capable of avoiding antagonists and inhibitors of zinc absorption, thereby increasing the bioavailability of zinc for the necessary biological processes in the prostate.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Asteris Radix et Rhizoma (AR) refers to the roots and rhizomes of Aster tataricus L., which is widely distributed throughout East Asia. AR has been consumed as a traditional medicine in Korea, Japan and China for the treatment of urologic symptoms. To date, however, the therapeutic effect of AR on benign prostatic hyperplasia (BPH) has not been investigated. AIM OF THE STUDY The present study evaluated the therapeutic effects of AR on a testosterone-induced BPH rats. MATERIALS AND METHODS We induced BPH to rats by subcutaneous injections (s.c) of testosterone propionate (TP) daily for four weeks. Rats were also administered daily oral gavage of AR (150 mg/kg) or vehicle. After four weeks of induction, all animals were euthanized humanely and their prostate glands were removed, weighed and processed for further analysis, including histopathological examination, real-time PCR, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay and Western blot analysis. RESULTS Administration of AR to TP-induced BPH rats considerably reduced prostate weight and concentrations of serum testosterone and prostate dihydrotestosterone (DHT). Epithelial thickness and expression of proliferating cell nuclear antigen (PCNA) were markedly suppressed by AR-treatment in the rats. Furthermore, the expression of the B-cell lymphoma 2 (Bcl-2) were reduced and expression of the Bcl-2-associated X protein (Bax) increased, resulting in significant reduction in Bcl-2/Bax ratio. In addition, AR decreased the level of pro-inflammatory cytokines, including interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). The expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) were reduced by AR treatment in a TP-induced BPH rat model. CONCLUSIONS AR alleviates BPH by promoting apoptosis and suppressing inflammation, indicating that AR may be used clinically to treat BPH accompanied by inflammation.

Abstract
Background Many factors could contribute to the cases of residual benign prostate hypertrophy (BPH) volume after transurethral resection of the prostate (TURP), such as age, obesity, testosterone level, and inflammation. The goal of this study was to determine the risk of tumor necrosis factor-α (TNF-α), transforming growth factor-β (TGF-β) in prostate tissue, serum prostate-specific antigen (PSA), serum testosterone, and age in promoting prostate volume progression after TURP. Patients and Methods This was a prospective cohort study on 83 BPH patients who underwent TURP at five hospitals in Bali, Indonesia. Trans-rectal ultrasonography (TRUS) was carried out to examine the prostate’s size. Three years after, we redo the TRUS examination to collect the data of the latest prostate size. TNF-α, TGF-β, serum PSA, testosterone, and age were registered for analysis. We used Pearson’s and Spearman’s correlation tests and multivariate analytic linear regression test (coefficient β) by SPSS 13.0 software. Results Age, testosterone, PSA, TNF-α, TGF-β were positively correlated to prostate’s volume progression. The prostate volume was strongly correlated with age (r= 0.749, p <0.001), PSA level (r=0.896, p <0.001), testosterone level (r=0.818, p <0.001), and TGF-β (r=0.609, p <0.001). The TNF-α level has a weak correlation to prostate’s volume progression (r=0.392, p <0.001). Conclusion TNF-α, TGF-β, PSA, testosterone, and age were significant as the risk factors in promoting the prostate volume progression after TURP.
