Transurethral Resection of the Prostate (TRUP) for the Treatment of Benign Prostatic Hyperplasia (BPH) in Central Cote D’Ivoire: Indications and Results

Background: Benign prostatic hyperplasia (BPH) is defined histologically as adenomyofromatous hyperplasia of the transitional zone of the prostate. It remains the most common benign tumour in men over the age of 50, and transurethral resection of the prostate (TURP) remains the surgical treatment of choice. Objectives: To determine the indications and present our results of transurethral resection of the prostate. Patients and Methods: After obtaining approval from the ethics committee of the private hospital and the university hospital of Bouaké (Côte d’Ivoire), we conducted a cross-sectional study of transurethral resection of the prostate (TURP) to treat benign prostatic hyperplasia (BPH) between January 2021 and April 2023. All patients and their families were informed beforehand and had signed an informed consent form. All patients with benign prostatic hyperplasia (BPH) with ultrasound weight of less than 80 grams were included. The following parameters were studied: age, reason for consultation, ultrasound prostate weight of benign prostatic hyperplasia, indication for TURP, duration of operation, blood loss, duration of post-PRT urinary drainage, length of hospital stay, morbidity and mortality, and outcome. Results: 39 patients with a mean age of 58.3 years (57-77 years) underwent transurethral resection of the prostate (TURP). TURP was indicated in 46.15% (n = 18) of cases of refractory acute urinary retention with failure of the urinary catheter removal test, 17.94% (n = 7) of cases of lower urinary tract disorders that were incapacitating despite treatment, 15.38% (n = 6) of cases of refractory or recurrent urinary tract infection, 10.25% (n = 4) of cases of failure of medical treatment and 10.25% (n = 4) of cases of iterative hematuria. The mean duration of TURP was 53.68 min (48-57), the mean weight of the resected prostate was 58.7 g (35 and 83 g), blood loss was minimal in 92.30% (n = 36), the mean duration of irrigation-washing was 2. 5 days (1-3 days), the mean time for urinary catheterisation was 2.45 days (3 and 4 days), 5.12% (n = 2) of patients presented complications such as hemorrhage compensated by a blood transfusion. One patient developed orchiepididymitis (2.56%). The average hospital stay was 3.75 days (3-5 days). Pathological examination was in favour of BPH in 92.3% (n = 36) and the coexistence of BPH and prostate adenocarcinoma in 7.69% (n = 3). The results of TURP were considered good in 94.87% (n = 37). Mortality was nil. Conclusion: In view of our results, TURP is a reliable, elegant minimally invasive technique with low morbidity and mortality.

The incidence rate and histological characteristics of intimal hyperplasia in elastase-induced experimental abdominal aortic aneurysms in mice

Intimal hyperplasia(IH)is a negative vascular remodeling after arterial injury.IH occasionally occurs in elastase-induced abdominal aortic aneurysm(AAA)mouse models.This study aims to clarify the incidence and histological characteristics of IH in aneurysmal mice.A retrospective study was conducted by including 42 male elastaseinduced mouse AAA models.The IH incidence,aortic diameters with or without IH,and hyperplasia lesional features of mice were analyzed.Among 42 elastase-induced AAA mouse models,10 mice developed mild IH(24%)and severe IH was found in only 2 mice(5%).The outer diameters of the AAA segments in mice with and without IH did not show significant difference.Both mild and severe IH lesions show strong smooth muscle cell positive staining,but endothelial cells were occasionally observed in severe IH lesions.There was obvious macrophage infiltration in the IH lesions of the AAA mouse models,especially in mice with severe IH.However,only a lower numbers of T cells and B cells were found in the IH lesion.Local cell-secreted matrix metalloproteinases(MMP)2 was highly expressed in all IH lesions,but MMP9 was only overexpressed in severe lesions.In conclusion,this study is the first to demonstrate the occurrence of aneurysmal IH and its histological characteristics in an elastaseinduced mouse AAA model.This will help researchers better understand this model,and optimize it for use in AAA-related research.

Transperineal laser ablation of the prostate as a treatment for benign prostatic hyperplasia and prostate cancer: The results of a Delphi consensus project

Objective: To evaluate transperineal laser ablation (TPLA) with Echolaser® (Echolaser® TPLA, Elesta S.p.A., Calenzano, Italy) as a treatment for benign prostatic hyperplasia (BPH) and prostate cancer (PCa) using the Delphi consensus method.Methods: Italian and international experts on BPH and PCa participated in a collaborative consensus project. During two rounds, they expressed their opinions on Echolaser® TPLA for the treatment of BPH and PCa answering online questionnaires on indications, methodology, and potential complications of this technology. Level of agreement or disagreement to reach consensus was set at 75%. If the consensus was not achieved, questions were modified after each round. A final round was performed during an online meeting, in which results were discussed and finalized.Results: Thirty-two out of forty invited experts participated and consensus was reached on all topics. Agreement was achieved on recommending Echolaser® TPLA as a treatment of BPH in patients with ample range of prostate volume, from <40 mL (80%) to >80 mL (80%), comorbidities (100%), antiplatelet or anticoagulant treatment (96%), indwelling catheter (77%), and strong will of preserving ejaculatory function (100%). Majority of respondents agreed that Echolaser® TPLA is a potential option for the treatment of localized PCa (78%) and recommended it for low-risk PCa (90%). During the final round, experts concluded that it can be used for intermediate-risk PCa and it should be proposed as an effective alternative to radical prostatectomy for patients with strong will of avoiding urinary incontinence and sexual dysfunction. Almost all participants agreed that the transperineal approach of this organ-sparing technique is safer than transrectal and transurethral approaches typical of other techniques (97% of agreement among experts). Pre-procedural assessment, technical aspects, post-procedural catheterization, pharmacological therapy, and expected outcomes were discussed, leading to statements and recommendations.Conclusion: Echolaser® TPLA is a safe and effective procedure that treats BPH and localized PCa with satisfactory functional and sexual outcomes.

Echinacoside attenuates glandular fibrosis in benign prostatic hyperplasia via inhibiting MKK6/MK2 signaling pathway

Background:Lower urinary tract symptoms commonly occur in the elderly population and seriously constrain the quality of life.Glandular fibrosis is an important pathobiological process in benign prostatic hyperplasia and is also a main inducing factor for benign prostatic hyperplasia-associated lower urinary tract symptoms.Cistanches species is an important herbal medicine resource and is traditionally used in ameliorating renal and prostatic defects.Methods:This study was to investigate the potential protective function of echinacoside(a bioactive compound from Cistanches)against prostatic fibrosis in mice and human benign prostatic hyperplasia epithelial-1 cell models.Results:It was found that echinacoside attenuated testosterone-induced prostatic hyperplasia and collagen deposition in mice,relieved prostate local inflammation and oxidative damage,and ameliorated prostatic epithelial-mesenchymal transition.Additionally,echinacoside inhibited the activation of the MKK6/MK2 signaling pathway both in vivo and in vitro.Conclusion:This study added new evidence for the anti-fibrotic function of echinacoside on the prostate and provided new insights for understanding its possible pharmacological mechanisms.

Metformin:A promising clinical therapeutical approach for BPH treatment via inhibiting dysregulated steroid hormones-induced prostatic epithelial cells proliferation

The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.However,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive relationship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met’s anti-proliferative effects were blocked by AMPK inhibitor or YAP1 overexpression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation.

Alleviatory effect of isoquercetin on benign prostatic hyperplasia via IGF-1/PI3K/Akt/mTOR pathway

We evaluated the effect of isoquercetin(quercetin-O-3-glucoside-quercetin,IQ)as a functional component of Abeliophyllum disistichum Nakai ethanol extract(ADLE)on prostate cell proliferation and apoptosis and its effects on the IGF-1/PI3K/Akt/mTOR pathway in benign prostatic hyperplasia(BPH).Metabolites in ADLE were analyzed using UHPLC-qTOF-MS and HPLC.IQ was orally administered(1 or 10 mg/kg)to a testosterone propionate-induced BPH rat model,and its effects on the prostate weight were evaluated.The effect of IQ on androgen receptor(AR)signaling was analyzed in LNCaP cells.Whether IGF-1 and IQ affect the IGF-1/PI3K/Akt/mTOR pathway in BPH-1 cells was also examined.The metabolites in ADLE were identified and quantified,which confirmed that ADLE contained abundant IQ(20.88 mg/g).IQ significantly reduced the prostate size in a concentration-dependent manner in a BPH rat model,and significantly decreased the expression of AR signaling factors in the rat prostate tissue and LNCaP cells in a concentration-dependent manner.IQ also inhibited the PI3K/AKT/mTOR pathway activated by IGF-1 treatment in BPH-1 cells.In BPH-1 cells,IQ led to G0/G1 arrest and suppressed the expression of proliferation factors while inducing apoptosis.Thus,IQ shows potential for use as a pharmaceutical and nutraceutical for BPH.

Efficacy of Bladder Neck Incision (BNI) Versus Transurethral Resection of Prostate (TURP) in Management of Benign Prostatic Hyperplasia (BPH) Causing Obstruction: A Randomised Controlled Study

Objective: To compare the efficacy of bladder neck incision (BNI) with transurethral resection of prostate (TURP) in the treatment of patients with urinary obstruction caused by benign prostatic hyperplasia (BPH) on the basis of short term follow up of 4 months. Patient and Methods: The study was conducted in Department of General Surgery in Maulana Azad Medical College, New Delhi. 60 men with proven clinical diagnosis of BPH of size 30 grams and less presenting with symptoms of bladder outlet obstruction (BOO) were randomised prospectively to undergo either of the two operative modalities. Preoperatively size of the prostate, symptom scoring (IPSS), peak flow rate (Qmax) were assessed. Postoperatively and during 4 months follow up the following data were collected—operative time, catheterisation period, hospital stay, blood loss, Qmax and IPSS. Results: Preoperative parameters in both the groups showed no statistically significant differences with respect to prostate size, Qmax and IPSS Scoring. At 4 months follow up Qmax increased from (6.35 ± 4.49) to (16.41 ± 2.28) in TURP group and (4.51 ± 3.57) to (15.95 ± 2.58) in BNI group. IPSS decreased from 18.70 to 5.7 in TURP group and 18.90 to 6.00 in BNI group. All differences were statistically significant. There was a statistically significant difference in operative time, blood loss, hospital stay, catheterisation timing favouring BNI. Conclusion: TURP and BNI are equally effective in providing symptomatic improvement. BNI has an upper hand in reference to operative time, hospital stay, duration of catheterisation and blood loss.

合并COPD的BPH患者尿流动力学特征研究

目的探讨BPH合并COPD患者的尿流动力学特点。方法选择78例BPH患者,分为合并COPD的BPH组(43例)和无合并COPD的BPH组(35例),分别检测2组患者的前列腺体积和尿流动力学参数。结果与无合并COPD的BPH组患者相比,合并COPD的BPH组患者的最大尿流率降低、最大尿流率时的逼尿肌压下降、膀胱收缩指数减少(P均<0.05)。2组BPH患者的年龄、前列腺体积、残余尿量、尿道阻力因子、梗阻指数压力和膀胱出口梗阻指数比较差异均无统计学意义(P均>0.05)。结论合并COPD的BPH患者具有膀胱逼尿肌收缩乏力的尿流动力学特征。

Alterations of gut microbiota diversity, composition and metabonomics in testosterone-induced benign prostatic hyperplasia rats

Background: Studies had shown many diseases affect the stability of human microbiota, but how this relates to benign prostatic hyperplasia(BPH) has not been well understood. Hence, this study aimed to investigate the regulation of BPH on gut microbiota composition and metabonomics.Methods: We analyzed gut samples from rats with BPH and healthy control rats, the gut microbiota composition and metabonomics were detected by 16S rDNA sequencing and liquid chromatography tandem mass spectrometry(LC–MS/MS).Results: High-throughput sequencing results showed that gut microbiota beta-diversity increased(P<0.01) in the BPH group vs. control group. Muribaculaceae(P<0.01), Turicibacteraceae(P<0.05), Turicibacter(P<0.01) and Coprococcus(P<0.01) were significantly decreased in the BPH group, whereas that of Mollicutes(P<0.05) and Prevotella(P<0.05)were significantly increased compared with the control group. Despite profound interindividual variability, the levels of several predominant genera were different. In addition, there were no statistically significant differences in several bacteria. BPH group vs. control group: Firmicutes(52.30% vs. 57.29%, P>0.05), Bacteroidetes(46.54% vs. 41.64%,P>0.05), Clostridia(50.89% vs. 54.66%, P>0.05), Ruminococcaceae(25.67% vs. 20.56%, P>0.05). LC–MS/MS of intestinal contents revealed that differential metabolites were mainly involved in cellular processes, environmental information processing, metabolism and organismal systems. The most important pathways were global and overview maps, lipid metabolism, amino acid metabolism, digestive system and endocrine system. Through enrichment analysis, we found that the differential metabolites were significantly enriched in metabolic pathways, steroid hormone biosynthesis,ovarian steroidogenesis, biosynthesis of unsaturated fatty acids and bile secretion. Pearson correlation analysis(R=0.94) showed that there was a strong correlation between Prevotellaceae, Corynebacteriaceae, Turicibacteraceae,Bifidobacteriaceae and differential metabolites.Conclusions: Our findings suggested an association between the gut microbiota and BPH, but the causal relationship between the two groups is unclear. Thus, further studies are warranted to elucidate the potential mechanisms and causal relationships between BPH and gut microbiota.

广西农家籼稻种质抗褐飞虱基因Bph40(t)的定位

褐飞虱是水稻生产危害中最严重的虫害之一,发掘水稻中抗褐飞虱的新基因并培育抗性品种是现今控制该虫害最有效的举措。广西农家种质——籼稻47-1连续3年的苗期、成株期对褐飞虱都表现一致高抗,遗传稳定性良好,具有明显的趋避性和抗生性,定位其抗性基因并探究其机理,对丰富抗褐飞虱基因的多样性和培育抗性水稻品种具有重大意义。本研究通过利用抗褐飞虱材料47-1与感褐飞虱材料9311杂交构建了包含91个单株的F_(2)群体,采用虫体增重法进行褐飞虱抗性表型鉴定。结果显示F_(2)群体抗性单株(虫体增重倍数≤1.1)与感性单株(虫体增重倍数>1.1)的数量比为61∶30,卡方检验(χ^(2)=3.081<χ_(0.01,1)^(2)=3.84)表明该性状的分离比符合1对显性基因的分离规律。基因定位在第4染色体标记04M0.453与04M3.688之间的区域内检测到一个褐飞虱抗性位点,与克隆的Bph40定位区间重叠。序列分析表明,47-1中Bph40(t)基因的CDS与已克隆的Bph40 CDS仅存在3个单碱基突变,共导致2个氨基酸差异,系统进化树分析发现两者的亲缘关系最近,表明该抗性基因就是Bph40的一个等位基因。

Saw Palmetto-Based Nutritional Supplement Prostataplex Relieves Symptoms of Benign Prostatic Hyperplasia (BPH) in Patients with Mild to Moderate BPH

The goal of this study was to assess the efficacy of the saw palmetto-based nutritional supplement, Prostataplex, for relieving the symptoms associated with benign prostatic hyperplasia (BPH) in men with mild to moderate degrees of BPH. A randomized, double-blind, placebo-controlled trial was performed in Shanghai, China. Eighty patients with BPH were randomly assigned to either the intervention group (39 cases) or control group (41 cases). Patients in the intervention group were administered Prostataplex orally and placebos were given to patients in the control group. The duration of treatment was 12 weeks in both groups. Following the intervention of Prostataplex, the maximum urinary flow rates (MFR), total scores of International Prostate Symptom Score (IPSS) and quality of life indicators were significantly better among the patients in the intervention group than those in the control group (P < 0.01 for all variables). Significant improvement of symptoms including dysuria, reducing nocturnal polyuria and increasing urinary flow rate was seen after two months of intervention, especially for the improvement of incomplete bladder emptying. Prostataplex has positive effects on improving symptoms as well as quality of life in men with mild to moderate BPH.

基于广义部分线性单指标的BPH与MS的关联性研究

为了尽早干预代谢综合征(metabolic syndrome, MS)的某些代谢因素降低良性前列腺增生(benign prostatic hyperplasia, BPH)的发病率并且为预后提供参考,探讨两者之间的相关性。前瞻性选取2006—2014年某体检队列数据作为研究对象,筛选MS和BPH的相关指标,采用统计学方法以及构建广义部分线性单指标模型(generalized partially linear single-index model, GPLSIM)分析BPH与MS之间的相关性。采用GPLSIM分析,结果显示PSA>3.9 ng/mL的体检者患BPH的几率比PSA≤3.9 ng/mL的体检者高55.8%;收缩压每增加约31 mmHg,患BPH的几率是原来的1.202倍;Glu>5.29 mmol/L的体检者患BPH的几率比Glu≤5.29 mmol/L的体检者高26.56%;ALT每增加约23 U/L,患BPH的几率是原来的0.815倍。可见,高血压、高密度脂蛋白、高血糖等代谢异常是BPH的危险因素,针对BPH的影响因素可以采取相应的干预措施。

Management of urethral strictures and stenosis caused by the endo-urological treatment of benign prostatic hyperplasiad-a single-center experience

Objective:Urethral stricture disease after endo-urological treatment of benign prostatic hyperplasia(BPH)is a sparsely described complication.We describe management of five categories of these strictures in this retrospective observational case series.Methods:One hundred and twenty-one patients presenting with symptoms of bladder outflow obstruction after endo-urological intervention for BPH from February 2016 to March 2019 were evaluated.Among them,76 were eligible for this study and underwent reconstructive surgery.Preoperative and postoperative assessments were done with symptom scores,uroflowmetry,ultrasound for post-void residue,and urethrogram.Any intervention during follow-up was classed as a failure.The recurrence and 95%confidence interval for recurrence percentage were calculated.Results:The following five categories of patients were identified:Bulbo-membranous(33[43.4%]),navicular fossa(21[27.6%]),penile/peno-bulbar(8[10.5%]),bladder neck stenosis(6[7.9%]),and multiple locations(8[10.5%]).The average age was 69 years(range:60-84 years).Overall average symptom score,flow rate,and post-void residue changed from 21 to 7,6 mL/s to 19 mL/s,and 210 mL to 20 mL,respectively.The average follow-up was 34 months(range:12-58 months).Overall recurrence and complication rates were 10.5%and 9.2%,respectively.The recurrence in each category was seen in 3,1,2,1,and 1 patient,respectively.Overall 95% confidence interval for recurrence percentage was 4.66-19.69.Conclusion:Urethral stricture disease is a major long-term complication of endo-urological treatment of BPH.The bulbo-membranous strictures need continence preserving approach.Navicular fossa strictures require minimally invasive and cosmetic consideration.Peno-bulbar strictures require judicious use of grafts and flaps.Bladder neck stenosis in this cohort could be treated with endoscopic measures.Multiple locations need treatment based on their sites in single-stage as far as possible.
