Background: The burden of common urologic diseases, including benign prostatic hyperplasia (BPH), urinary tract infections (UTI), urolithiasis, bladder cancer, kidney cancer, and prostate cancer, varies both geographically and within specific regions. It is essential to conduct a comprehensive and precise assessment of the global burden of urologic diseases. Methods: We obtained data on incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) for the aforementioned urologic diseases by age, sex, location, and year from the Global Burden of Disease (GBD) 2021. We analyzed the burden associated with urologic diseases based on socio-demographic index (SDI) and attributable risk factors. The trends in burden over time were assessed using estimated annual percentage changes (EAPC) along with a 95% confidence interval (CI). Results: In 2021, BPH and UTI were the leading causes of age-standardized incidence rate (ASIR) and age-standardized prevalence rate (ASPR), with rates of 5531.88 and 2782.59 per 100,000 persons, respectively. Prostate cancer was the leading cause of both age-standardized mortality rate (ASMR) and age-standardized DALYs rate (ASDR), with rates of 12.63 and 217.83 per 100,000 persons, respectively. From 1990 to 2021, there was an upward trend in ASIR, ASPR, ASMR, and ASDR for UTI, while urolithiasis showed a downward trend. The middle and low-middle SDI quintile levels exhibited higher incidence, prevalence, mortality, and DALYs related to UTI, urolithiasis, and BPH, while the high and high-middle SDI quintile levels showed higher rates for the three cancers. The burden of these six urologic diseases displayed diverse age and sex distribution patterns. In 2021, a high body mass index (BMI) contributed to 20.07% of kidney cancer deaths worldwide, while smoking accounted for 26.48% of bladder cancer deaths and 3.00% of prostate cancer deaths. Conclusions: The global burden of 6 urologic diseases presents a significant public health challenge. Urgent international collaboration is essential to advance the improvement of urologic disease management, encompassing the development of effective diagnostic screening tools and the implementation of high-quality prevention and treatment strategies.

Objective: Chronological age (CAge), biological age (BAge), and accelerated age (AAge) are all important for aging‐related diseases. CAge is a known risk factor for benign prostatic hyperplasia (BPH); However, the evidence of association of BAge and AAge with BPH is limited. This study aimed to evaluate the association of CAge, Bage, and AAge with BPH in a large prospective cohort. Method: A total of 135,933 males without BPH at enrolment were extracted from the UK biobank. We calculated three BAge measures (Klemera–Doubal method, KDM; PhenoAge; homeostatic dysregulation, HD) based on 16 biomarkers. Additionally, we calculated KDM‐BAge and PhenoAge‐BAge measures based on the Levine method. The KDM‐AAge and PhenoAge‐AAge were assessed by the difference between CAge and BAge and were standardized (mean = 0 and standard deviation [SD] = 1). Cox proportional hazard models were applied to assess the associations of CAge, Bage, and AAge with incident BPH risk. Results: During a median follow‐up of 13.150 years, 11,811 (8.690%) incident BPH were identified. Advanced CAge and BAge measures were associated with an increased risk of BPH, showing threshold effects at a later age (all P for nonlinearity <0.001). Nonlinear relationships between AAge measures and risk of BPH were also found for KDM‐AAge (P = 0.041) and PhenoAge‐AAge (P = 0.020). Compared to the balance comparison group (−1 SD < AAge < 1 SD), the accelerated aging group (AAge > 2 SD) had a significantly elevated BPH risk with hazard ratio (HR) of 1.115 (95% CI, 1.000–1.223) for KDM‐AAge and 1.180 (95% CI, 1.068–1.303) for PhenoAge‐AAge, respectively. For PhenoAge‐AAge, subgroup analysis of the accelerated aging group showed an increased HR of 1.904 (95% CI, 1.374–2.639) in males with CAge <50 years and 1.233 (95% CI, 1.088–1.397) in those having testosterone levels <12 nmol/L. Moreover, AAge‐associated risk of BPH was independent of and additive to genetic risk. Conclusions: Biological aging is an independent and modifiable risk factor for BPH. We suggest performing active health interventions to slow biological aging, which will help mitigate the progression of prostate aging and further reduce the burden of BPH. [ABSTRACT FROM AUTHOR]

Background: Obesity (waist circumference, body mass index (BMI)) and lifestyle factors (dietary habits, smoking, alcohol drinking, Sedentary behavior) have been associated with risk of benign prostatic hyperplasia (BPH) in observational studies, but whether these associations are causal is unclear.Methods: We performed a univariable and multivariable Mendelian randomization study to evaluate these associations. Genetic instruments associated with exposures at the genome-wide significance level (P < 5 × 10-8) were selected from corresponding genome-wide associations studies (n = 216,590 to 1,232,091 individuals). Summary-level data for BPH were obtained from the UK Biobank (14,126 cases and 169,762 non-cases) and FinnGen consortium (13,118 cases and 72,799 non-cases). Results from UK Biobank and FinnGen consortium were combined using fixed-effect meta-analysis.Results: The combined odds ratios (ORs) of BPH were 1.24 (95% confidence interval (CI), 1.07-1.43, P = 0.0045), 1.08 (95% CI 1.01-1.17, P = 0.0175), 0.94 (95% CI 0.67-1.30, P = 0.6891), 1.29 (95% CI 0.88-1.89, P = 0.1922), 1.23 (95% CI 0.85-1.78, P = 0.2623), and 1.04 (95% CI 0.76-1.42, P = 0.8165) for one standard deviation (SD) increase in waist circumference, BMI, and relative carbohydrate, fat, protein and sugar intake, 1.05 (95% CI 0.92-1.20, P = 0.4581) for one SD increase in prevalence of smoking initiation, 1.10 (95% CI 0.96-1.26, P = 0.1725) and 0.84 (95% CI 0.69-1.02, P = 0.0741) for one SD increase of log-transformed smoking per day and drinks per week, and 1.31 (95% CI 1.08-1.58, P = 0.0051) for one SD increase in sedentary behavior. Genetically predicted waist circumference (OR = 1.26, 95% CI 1.11-1.43, P = 0.0004) and sedentary behavior (OR = 1.14, 95% CI 1.05-1.23, P = 0.0021) were associated with BPH after the adjustment of BMI.Conclusion: This study supports independent causal roles of high waist circumference, BMI and sedentary behavior in BPH.

Objectives. To compare the clinical outcomes of using different hemostatic agents after transurethral plasmakinetic resection of the prostate (TUPKP) in benign prostatic hyperplasia (BPH) patients. Methods. The patients were divided into 5 groups according to the hemostatic agents used after TUPKP, including the haemocoagulase agkistrodon for injection (HCA), hemocoagulase for injection (HC), hemocoagulase bothrops atrox for injection (HCB), ethylenediamine diaceturate injection (EDD), and tranexamic acid (TXA). Propensity score matching was performed based on age, body mass index, prostate volume, hypertension status, fasting blood glucose, smoking, and drinking history. The hospitalization time, bladder irrigation time, indwelling catheterization time, the patency of urine flow, and blood transfusion records were used as outcome indicators to compare the clinical effects of these five agents. Results. We finally matched 65 pairs receiving HCA or HC, 71 pairs receiving HCA or HCB, 38 pairs receiving HCA or TXA, and 29 pairs receiving HCA or EDD. Compared with HC, HCA given during the perioperative period significantly reduced the median hospitalization time [7.00 days (5.00, 8.00) vs. 9.00 days (8.00, 10.00); p < 0.001 ] and median catheterization time (109.00 hours [88.00, 129.00] vs. 164.00 hours [114.00, 189.00], p < 0.001). Compared with EDD, the median hospitalization time (7.00 days [6.00, 8.00] vs. 10.00 days [8.00, 11.00]; p < 0.001) and median catheterization time (113.00 hours [95.00, 143.00] vs. 160.00 hours [139.00, 168.00]; p < 0.001) were also significant shorter in HCA group. Compared with HCB, median bladder irrigation time (45.00 hours [27.00, 71.00] vs. 49.00 hours [45.00, 72.00]; p = 0.04) was shorter in the HCA group. However, there were no statistical differences in outcomes between HCA and TXA. Conclusions. HCA probably has an advantage over HC, HCB, and EDD in reducing the hospitalization time, catheterization time, and bladder irrigation time among BPH patients undergoing TUPKP.

The objective of this study was to compare the efficacy and safety of 10 different surgical treatments for benign prostatic hyperplasia (BPH) with volume >60 mL. A systematic literature review and network meta-analysis of randomized controlled trials (RCTs) within a Bayesian framework was performed. A total of 52 parallel-group RCTs included, reporting on 6,947 participants, comparing open prostatectomy (OP), monopolar/bipolar transurethral resection of prostate (monopolar/ bipolar TURP), thulium, holmium and diode laser enucleation of prostate (LEP), bipolar enucleation of prostate, potassium titanyl phosphate laser vaporization of prostate (KTP LVP), bipolar vaporization of prostate (bipolar VP), and laparoscopic simple prostatectomy (laparoscope SP). Compared with OP, laparoscope SP identified better maximal flow rate (Qmax; mean differences [MDs] = 2.89 mL/s) at the 24th month, but bipolar VP demonstrated worse Qmax (MD = −3.20 mL/s) and International Prostate Symptom Score (IPSS; MD = 2.60) at the 12th month. Holmium LEP (MD = 1.37) demonstrated better International Index of Erectile Function–5 at the 12th month compared with OP. However, compared with OP, KTP LVP demonstrated worse postvoid residual volume (PVR) at the sixth (MD = 10.42 mL) and 12th month (MD = 5.89 mL) and monopolar TURP (MD = 6.9 mL) demonstrated worse PVR at the 12th month. Eight new surgical methods for BPH with volume >60 mL appeared to be superior in safety compared with OP and monopolar TURP due to fewer complications. Bipolar VP and KTP LVP maybe not suitable for prostates more than 60 mL due to short- and middle-term worse Qmax, IPSS, and PVR than OP. [ABSTRACT FROM AUTHOR]

Nowadays, human microbiome research is rapidly growing and emerging evidence has witnessed the critical role that oral microbiome plays in the process of human health and disease. Oral microbial dysbiosis has been confirmed as a contributory cause for diseases in multiple body systems, ranging from the oral cavity to the gastrointestinal, endocrine, immune, cardiovascular, and even nervous system. As research progressing, oral microbiome‐based diagnosis and therapy are proposed and applied, which may represent potential drug targets in systemic diseases. Recent studies have uncovered the possible association between periodontal disease and prostatic disease, suggesting new prevention and therapeutic treatment for the disease by targeting periodontal pathogens. Thus, we performed this review to first explore the association between the oral microbiome and prostatic disease, according to current knowledge based on published articles, and then mainly focus on the underlying molecular and cellular mechanisms and the potential prevention and treatment derived from these mechanistic studies.

Objective: To investigate the correlation of clinical measurements on normal and abnormal fasting blood glucose (FBG) with benign prostatic hyperplasia (BPH).Methods: From September 2016 to January 2018, 771 BPH patients were enrolled for further selection. The eligible patients were divided into normal FBG, impaired fasting glucose (IFG), and high risk of type 2 diabetes mellitus (HR-T2DM) groups. Then, relevant parameters were compared among these three groups using Pearson's correlation coefficient.Results: Finally including 443 patients with normal FBG, 113 with IFG and 56 with HR-T2DM. Height, weight, body mass index, smoking status, hemoglobin, serum Na+, serum Cl-, and serum Ca2+ were significantly different between normal and abnormal FBG groups. In IFG/HR-T2DM group, obviously connections were demonstrated for weight with prostate volume (PV), for serum Na+, PV, and serum Cl- with total prostate-specific antigen (t-PSA), for FBG with international prostate symptom score (IPSS). In normal FBG group, significant correlations of age, weight, body mass index, hemoglobin, and serum Ca2+ with PV, of age, systolic blood pressure, PV, and serum Cl- with t-PSA; and of FBG, hemoglobin, and serum Na+ with IPSS were also observed.Conclusions: Our study suggests that FBG level probably plays an important role in BPH.

Objective: Many published studies have investigated the association between CYP17 rs743572 polymorphism and benign prostatic hyperplasia (BPH) susceptibility but have yielded inconsistent results. Hence, we performed this meta-analysis using the multivariate statistic method to address a more precise association. Methods: Case-control or cohort studies with adequate genotype distribution or minor allele frequency (MAF) were identified by searching the PubMed, Embase, and Web of Science databases up to December, 2018. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to estimate the association between CYP17 rs743572 polymorphism and BPH susceptibility. Results: Pooled MAFs of 13 studies were 37% in Caucasians and 56% in Orientals, respectively. Pooled results of 8 studies suggested that CYP17 rs743572 was not associated with the BPH susceptibility in the overall population (OR = 0.98, 95% CI: 0.80–1.20 for A2 vs. A1; OR = 0.99, 95% CI: 0.79–1.25 for A1/A2 vs. A1/A1; OR = 0.97, 95% CI: 0.62–1.53 for A2/A2 vs. A1/A1). Sensitivity analysis showed the results were robust. Subgroup analysis based on ethnicity suggested that, in Orientals, A2 allele carriers had a 28% lower risk of developing BPH compared with A1 allele carriers, and the risk of BPH is 47% lower in A2/A2 genotype carriers compared with A1/A1 genotype carriers. No significant association was observed in Caucasians. Conclusion: In conclusion, our study indicates a negative association between CYP17 and BPH in Orientals. However, due to limited sample size, the conclusion should be interpreted with caution. [ABSTRACT FROM AUTHOR]

Objective: To discover the correlation of clinical and physiological measures for benign prostatic hyperplasia in hypertensive and normotensive patients. Methods: From September 2016 to October 2017, 435 patients were enrolled for further selection. The parameters evaluated for eligible patients included prostate volume, systolic blood pressure, diastolic blood pressure, international prostate symptom score, etc. Then the eligible patients were divided into two groups according to hypertension condition, and the clinical and physiological parameters were compared between two groups. The Pearson's correlation coefficient was used to test the linearity of the relationships of these clinical and physiological components with prostate volume, total prostate specific antigen, and international prostate symptom score. Results: Finally, 350 patients were involved in this study, including 117 with hypertension and 233 without hypertension. Weight, body mass index, systolic blood pressure, and diastolic blood pressure were significantly different between the hypertension and normotension groups. In the normotension group, there were positive correlations between weight, body mass index, age, and prostate volume; between fasting blood sugar, systolic blood pressure, diastolic blood pressure, and total prostate specific antigen; between fasting blood sugar and international prostate symptom score. In the hypertension group, there were positive correlations between age and total prostate specific antigen and international prostate symptom score; between weight and prostate volume; between systolic blood pressure and total prostate specific antigen. Conclusion: This study indicated that there might be no significant association between hypertension and prostate volume. [ABSTRACT FROM AUTHOR]

Abstract: Bladder cancer and benign prostatic hyperplasia have been two very common diseases among the elderly men, especially with the aging of the population in the world. We have designed a study to investigate the clinical effect of interventional therapy for plasmakinetic resection of the prostate and plasmakinetic resection of the bladder, which is called “BPSC” (The bladder cancer and benign prostatic hyperplasia study in Chinese population). The BPSC is not only a specific study, it is made up of many studies. In this article, we introduced the research background, source, name, study framework, study management and further direction of BPSC project. We hope this process will contribute to the growth of the database through sharing data and enriching the evidence of bladder cancer and benign prostatic hyperplasia in the Chinese population, thereby finally improving the accessibility of these important findings for doctors, researchers, and patients.

Purpose: This study aimed to evaluate the efficacy and safety of transurethral plasmakinetic resection of the prostate (PKRP) for the treatment of patients with benign prostatic hyperplasia (BPH) in men with prostate volume >80 cc. Patients and Methods: From January 2010 to December 2011, 120 patients were included in our study; among these patients, 66 had prostate sizes of 80 cc to 100 cc and 54 had prostate sizes >100 cc. Pre-, peri- and postoperative evaluations were performed. Results: The mean operative duration of PKRP was 112 minutes, and the mean resected tissue weight was 60.01 g. Hemoglobin level decreased by 0.65±0.52 g/dL, and serum sodium content decreased by 0.06±2.62 mmol/L. The mean catheterization time was 83.05 hours, and the mean hospital stay was 12.47 days. The short follow-up time (30 months) demonstrated significant improvement in International Prostate Symptom Score, quality of life, and postvoid residual volume compared with preoperative characteristics. One patient underwent reoperation because of a blood clot in the bladder. Twelve patients complained of retrograde ejaculation. No patient experienced urinary incontinence. Conclusions: PKRP is safe and efficacious for men with BPH who have a large prostate (volume >80 cc). [ABSTRACT FROM AUTHOR]

Background: Holmium laser enucleation (HoLEP) in surgical treatment of benign prostate hyperplasia (BPH) potentially offers advantages over transurethral resection of the prostate (TURP). Methods: Published randomized controlled trials (RCTs) were identified from PubMed, EMBASE, Science Citation Index, and the Cochrane Library up to October 10, 2013 (updated on February 5, 2014). After methodological quality assessment and data extraction, meta-analysis was performed using STATA 12.0 and Trial Sequential Analysis (TSA) 0.9 software. Results: Fifteen studies including 8 RCTs involving 855 patients met the criteria. The results of meta-analysis showed that: a) efficacy indicators: there was no significant difference in quality of life between the two groups (P>0.05), but compared with the TURP group, Qmax was better at 3 months and 12 months, PVR was less at 6, 12 months, and IPSS was lower at 12 months in the HoLEP, b) safety indicators: compared with the TURP, HoLEP had less blood transfusion (RR 0.17, 95% CI 0.06 to 0.47), but there was no significant difference in early and late postoperative complications (P>0.05), and c) perioperative indicators: HoLEP was associated with longer operation time (WMD 14.19 min, 95% CI 6.30 to 22.08 min), shorter catheterization time (WMD −19.97 h, 95% CI −24.24 to −15.70 h) and hospital stay (WMD −25.25 h, 95% CI −29.81 to −20.68 h). Conclusions: In conventional meta-analyses, there is no clinically relevant difference in early and late postoperative complications between the two techniques, but HoLEP is preferable due to advantage in the curative effect, less blood transfusion rate, shorter catheterization duration time and hospital stay. However, trial sequential analysis does not allow us to draw any solid conclusion in overall clinical benefit comparison between the two approaches. Further large, well-designed, multicentre/international RCTs with long-term data and the comparison between the two approaches remain open. [ABSTRACT FROM AUTHOR]

The aim of this study was to compare plasmakinetic resection of the prostate (PKRP) with transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH) in terms of efficacy and safety. Published RCTs were searched from PubMed, Embase, Science Citation Index, and Cochrane Library up to April 10, 2014. After methodological quality assessment and data extraction, meta-analysis was performed using the STATA 12.0 software. 18 reports of 16 RCTs were included in this analysis. Meta-analyses showed that PKRP significantly improved Qmax at 12 months, but no significant difference was found for other efficacy outcomes. In terms of safety, treatment of PKRP was associated with reduced drop in serum sodium, lower TUR syndrome, reduced need of blood transfusion, clot retention, and shorter catheterization time and hospital stay; in contrast, there were no significant differences in the analysis of operative time, postoperative fever, and long-term postoperative complications. In summary, current evidence suggests that, although PKRP and TURP are both effective for BPH, PKRP is associated with additional potential benefits in efficacy and more favorable safety profile. It may be possible that PKRP may replace the TURP in the future and become a new standard surgical procedure. [ABSTRACT FROM AUTHOR]
