Evaluation of greenlight photoselective vaporization of the prostate for the treatment of high-risk patients with benign prostatic hyperplasia

Aim： To explore the feasibility and safety of greenlight photoselective vaporization of the prostate （PVP） on high-risk patients presenting with lower urinary tract symptoms suggestive of benign prostatic hyperplasia （BPH） and to evaluate their clinical and voiding outcome. Methods： A total of 85 high-risk patients with obstructive BPH underwent PVP with an 80 W potassium-titanyl-phosphate laser, which was delivered through a side-deflecting fiber with a 23 Fr continuous flow cystoscope. Operative time, blood loss, indwelling catheterzation, international prostate symptom score （IPSS）, quality of life score （QoL）, uroflowmetry, postvoid residual urine volume and short-term complication rates were evaluated for all patients. Results： All patients got through the perioperative period safely. The chief advantages of PVP were： short operative time （25.6 ± 7.6 min）, little bleeding loss （56.8 ± 14.3 mL） and short indwelling catheterization （1.6 ± 0.8 d）. The IPSS and QoL decreased from （29.6 ± 5.4） and （5.4 ± 0.6） to （9.5 ± 2.6） and （1.3 ± 0.6）, respectively. The vast majority of patients were satisfied with voiding outcome. The mean maximal urinary flow rate increased to 17.8 mL/s and postvoid residual urine volume decreased to 55.6 mL. These results are significantly different from preoperative data （P 〈 0.05）. No patient required blood transfusion or fluid absorption. There were few complications and very high patient satisfaction after operation. Conclusion： PVP has a short operative time and high tolerance, and is safe, effective and minimally invasive for high-risk patients, therefore it might be considered as a good alternative treatment for high-risk patients with obstructive urinary symptoms as a result of BPH.

Sonablate-500^(TM) Transrectal High-intensity Focused Ultrasound (HIFU) for Benign Prostatic Hyperplasia Patients

To evaluate the safety and efficacy of transrectal high-intensity focused ultrasound （HIFU） in the treatment of benign prostatic hyperplasia （BPH）, serial studies were conducted in 150 BPH patients before and 30 min, 1, 2, 6 and 12 month（s） after Sonablate-500TM HIFU treatment. A silicon-coated indwelling 16F latex catheter was placed during the determination of the therapy zone. Preoperative and postoperative evaluations were made by using the international prostate symptom score （IPSS）, quality of life （QOL）, uroflowmetric findings and transrectal ultrasound, and incidence of complications. The cystourethrography was done in 23 patients within 1 year postoperatively. The results showed that after HIFU treatment, IPSS and QOL scores were significantly decreased at 1, 2, 6 and 12 month（s） （P〈0.01）. Maximum urine flow rate （6.0 to 17.2 mL/s, P〈0.01）, PVR （75.0 to 30.3, P〈0.01） and prostatic volume （65.0 to 38.1 mL, P〈0.05） were significantly improved 12 months after the operation. Recurrent urinary retention （17=2） and urethrorectal fistula （n=1） occurred at the 15th postoperative day. The duration of the HIFU prostate ablation was 25-90 min. The mean time for an indwelling catheter was 3-19 days. These data demonstrate that treatment of BPH with Sonab- late-500TM HIFU is safe and effective.

Periodontal disease and risk of benign prostate hyperplasia: a cross-sectional study

Background:Both periodontal disease and benign prostatic hyperplasia are age-related diseases that affect millions of people worldwide.Hence,this study aimed to investigate the association between periodontal disease and the risk of benign prostatic hyperplasia.Methods:A total of 4930 participants were selected from an available health examination that was carried out in 2017,only males were considered for further analysis.All eligible males were divided into benign prostatic hyperplasia and normal groups,the benign prostatic hyperplasia group was then divided into prostate volume≤60 g and>60 g subgroups;all their periodontal status was extracted and then into normal(CPI score of 0),periodontal disease(CPI score between 1 and 4),and periodontitis(CPI score between 3 and 4)groups.The correlation between periodontal disease and benign prostatic hyperplasia was investigated using logistic regression analyses and greedy matching case-control analysis.Subgroup analysis based on prostate volume was also performed.All analyses were conducted with SAS 9.4 software.Results:A total of 2171 males were selected for this analysis.The presence of periodontal disease significantly increased the risk of benign prostatic hyperplasia by 1.68 times(OR=1.68,95%CI:1.26–2.24),and individuals with periodontitis showed a higher risk(OR=4.18,95%CI:2.75–6.35).In addition,among matched cases and controls,this association remained robust(periodontal disease:OR=1.85,95%CI:1.30–2.64;periodontitis:OR=4.83,95%CI:2.57–9.07).Subgroup analysis revealed that periodontal disease significantly increased benign prostate hyperplasia risk as well(for prostate volume≤60 g:OR=1.64,95%CI:1.22–2.20;for volume>60 g:OR=2.17,95%CI:1.04–4.53),and there was a higher risk in the group with a prostate volume greater than 60 g.Conclusions:Periodontal disease is significantly and positively associated with an increased risk of benign prostatic hyperplasia.Further validation studies should be performed to explore the relationship between periodontal treatment and benign prostate hyperplasia.

A Review of Risk Factors for Predicting Urinary Incontinence after Benign Prostatic Hyperplasia

Benign prostatic hyperplasia (BPH) is one of the common diseases in middle-aged and elderly men, and its clinical symptoms include storage symptoms, voiding symptoms and post-urination symptoms. Surgery is an important treatment method for benign prostatic hyperplasia. It is suitable for BPH patients with moderate to severe LUTS (Lower Urinary Tract Symptoms) and has significantly affected the quality of life. The surgical methods include transurethral resection of the prostate and transurethral holmium laser enucleation of the prostate. While offering a high chance of cure, it also brings some complications, including postoperative urinary incontinence. This article mainly reviews the urinary incontinence after transurethral prostate surgery in recent years and analyzes its risk factors, and summarizes the experience for further prediction and reduction of the incidence of urinary incontinence.

Correlation between molecular biomarkers and risk factors for the clinical progression of benign prostatic hyperplasia using tissue microarray immunostaining

Background The pathogenesis of benign prostatic hyperplasia （BPH） has been widely studied,and several biomarkers are known to play roles in its development.This study aimed to investigate the possible role of cysteine-rich protein 61 （CYR61）,vascular endothelial growth factor （VEGF）,androgen receptor （AR）,interleukin-6 （IL-6）,cytochrome c,caspase-3,and proliferating cell nuclear antigen （PCNA） in the clinical progression of BPH.Methods Tissue specimens from 96 BPH cases who underwent transurethral resection of the prostate were processed and transferred to tissue microarrays.Patient age,prostate volume,serum prostate-specific antigen （PSA） level,and International Prostate Symptom Score （IPSS） of all BPH cases were collected before surgery.The expression of CYR61,VEGF,AR,IL-6,cytochrome c,caspase-3,and PCNA was examined by immunostaining in the BPH specimens,and any possible correlation between the different biomarkers and risk factors for BPH clinical progression was analyzed.Results The expression of CYR61,VEGF,AR,IL-6,cytochrome c,caspase-3,and PCNA in the BPH cases was 68.8％ （66/96）,77.1％ （74/96）,43.8％ （42/96）,31.3％ （30/96）,35.4％ （34/96）,56.3％ （54/96）,and 29.2％ （28/96）,respectively.The expression of both CYR61 and VEGF was positively correlated with patient age,prostate volume,and serum PSA level （P ＜0.05）.Furthermore,cytochrome c and caspase-3 expression were inversely related to prostate volume （P ＜0.05）,and AR expression was positively related to serum PSA level （P ＜0.05）.Conclusion CYR61 and VEGF expression might serve as biomarkers for predicting the clinical progression of BPH due to effects on stromal cell proliferation and angiogenesis.

Comparison of the predictive value of anthropometric indicators for the risk of benign prostatic hyperplasia in southern China

This study aimed to compare the predictive value of six selected anthropometric indicators for benign prostatic hyperplasia(BPH).Males over 50 years of age who underwent health examinations at the Health Management Center of the Second Xiangya Hospital,Central South University(Changsha,China)from June to December 2020 were enrolled in this study.The characteristic data were collected,including basic anthropometric indices,lipid parameters,six anthropometric indicators,prostate-specific antigen,and total prostate volume.The odds ratios(ORs)with 95%confidence intervals(95%CIs)for all anthropometric parameters and BPH were calculated using binary logistic regression.To assess the diagnostic capability of each indicator for BPH and identify the appropriate cutoff values,receiver operating characteristic(ROC)curves and the related areas under the curves(AUCs)were utilized.All six indicators had diagnostic value for BPH(all P≤0.001).The visceral adiposity index(VAI;AUC:0.797,95%CI:0.759–0.834)had the highest AUC and therefore the highest diagnostic value.This was followed by the cardiometabolic index(CMI;AUC:0.792,95%CI:0.753–0.831),lipid accumulation product(LAP;AUC:0.766,95%CI:0.723–0.809),waist-to-hip ratio(WHR;AUC:0.660,95%CI:0.609–0.712),waist-to-height ratio(WHtR;AUC:0.639,95%CI:0.587–0.691),and body mass index(BMI;AUC:0.592,95%CI:0.540–0.643).The sensitivity of CMI was the highest(92.1%),and WHtR had the highest specificity of 94.1%.CMI consistently showed the highest OR in the binary logistic regression analysis.BMI,WHtR,WHR,VAI,CMI,and LAP all influence the occurrence of BPH in middle-aged and older men(all P≤0.001),and CMI is the best predictor of BPH.

目的:450 nm蓝激光半导体治疗机行经尿道蓝激光汽化术治疗高危前列腺增生(BPH)患者临床疗效评价。方法:纳入青海红十字医院泌尿外科2023年1月至9月BPH患者80例,随机数表法分为研究组和对照组,每组40例。研究组采用经尿道蓝激光汽化术,对照组采用经尿道前列腺电切术(TURP)。对比两组患者手术时间、术后膀胱持续冲洗及导尿管留置时间、术中术后血红蛋白下降值,下床活动时间、前列腺症状改善及并发症发生情况。结果:80例BPH患者均顺利完成手术,TURP组8例患者术中行膀胱造瘘术,研究组术中均未行膀胱造瘘术,研究组较对照组手术耗时短、出血量少、术后膀胱冲洗及导尿管留置时间短、下床活动时间早(P<0.05)。两组患者与术前比较IPSS、PRV均明显下降、Qmax显著升高(P<0.05),术后两组患者组间比较IPSS、PRV、Qmax无显著性差异(P>0.05)。总体并发症发生率低于对照组(P<0.05)结论:经尿道450 nm蓝激光汽化术治疗BPH止血高效、手术耗时短、术中膀胱造瘘率低、并发症少,可有效缩短膀胱冲洗及导尿管留置时间,术后排尿良好,治疗高风险性BPH具有一定的优势性。

勃起功能障碍和下尿路症状在良性前列腺增生患者中的合并发生率及危险因素分析

目的:研究勃起功能障碍(ED)和下尿路症状(LUTS)在良性前列腺增生(BPH)人群中的合并发生率及危险因素分析。方法:2020年1月至2023年1月在中南大学湘雅二医院门诊就诊的BPH患者,根据纳入和排除标准确定纳入本研究的对象,收集一般资料和临床资料(包括年龄、身高、体重、腹围、臀围、血压、血常规、肝功能、肾功能、血脂和空腹血糖等),通过问卷调查进行国际前列腺症状评分(IPSS)、生活质量评分(QOL评分)和国际勃起功能指数(IIEF-5)评分。采用SPSS 22.0软件进行数据处理与分析。结果:ED合并LUTS在BPH患者各年龄组发生率分别为45~49岁组36.46%,50~54岁组43.72%,55~59岁组53.66%,60~64岁组69.23%,65~70岁组78.74%。LAP、VAI、TyG、HSI、BMI、WHtR、WHR、TG/HDL-C与IPSS得分呈正相关,与IIEF-5得分呈负相关;HDL-C/TC与IPSS得分呈负相关,与IIEF-5得分呈正相关。结论:ED合并LUTS在BPH患者中的发生率随年龄增加而增高,高血压、血脂异常、糖尿病、身高体重指数(BMI)、生活方式可能是ED合并LUTS发生的危险因素,LAP、VAI、TyG、HSI、BMI、WHtR、WHR、TG/HDL-C可有效评估ED合并LUTS在BPH患者中发生的风险。

良性前列腺增生患者行经尿道切除术后发生尿路感染相关危险因素调查与防护措施分析

目的分析良性前列腺增生(BPH)患者行经尿道切除术(TURP)后发生尿路感染相关危险因素与防护措施。方法选择于我院行TURP的80例BPH患者,根据尿路感染发生情况分为两组,分析BPH患者行TURP术后发生尿路感染的危险因素,并制定防护措施。结果80例BPH患者中有15例患者发生术后尿路感染。单因素分析显示,感染组术前进行导尿术、合并糖尿病、术前未使用抗生素、导尿管留置时间>5 d占比均高于未感染组(P<0.05)。Logistic回归分析结果显示,术前进行导尿术、合并糖尿病、术前未使用抗生素、导尿管留置时间>5 d是BPH患者行TURP术后发生尿路感染的独立危险因素(OR>1,P<0.05)。结论BPH患者TURP术后易发生尿路感染,术前进行导尿术、合并糖尿病、术前未使用抗生素、导尿管留置时间>5d是其独立危险因素,及时制定防护措施可减少尿路感染发生。

基于IMB模型的风险预警护理对良性前列腺增生患者康复的影响

目的 探讨基于信息-动机-行为技巧(IMB)模型的风险预警护理对良性前列腺增生患者康复的影响。方法 选取我院2022年08月到2023年08月收治的82例良性前列腺增生患者,应用随机数字表法将其分为观察组与对照组,各组均为41例。所有患者均采取经尿道等离子电切术治疗,对照组采取围术期常规护理,观察组在对照组基础上增加IMB模型的风险预警护理,分别在护理前后应用自我护理能力量表(ESCA)对患者自我护理能力进行评价,对比两组首次下床时间、尿管拔除时间、首次进食时间和住院时间,最后对比两组并发症发生情况。结果 护理后两组的健康知识水平、自我护理技能、自护责任感、自我概念相关ESCA评分均升高,且观察组高于对照组(P<0.05);观察组患者首次下床时间、尿管拔除时间、首次进食时间和住院时间明显低于对照组(P<0.05);观察组术后并发症发生率明显低于对照组(P<0.05)。结论 基于IMB模型的风险预警护理对良性前列腺增生患者围术期护理效果显著,可提升患者自我护理能力,促进其早日康复,辅助降低术后并发症发生率。
