We aimed to determine what types of events may influence patient search habits related to surgical BPH treatments.Methods:Google Trends was used to determine the frequency of searches for different minimally invasive and prostatic ablative treatments for BPH in the United States. The procedures including transurethral resection of the prostate (TURP), Aquablation therapy (Aquablation), Greenlight laser therapy (Greenlight), transurethral needle ablation, transurethral microwave thermotherapy, Urolift (prostatic urethral lift [PUL]), Rezum, iTind, holmium laser enucleation of the prostate, simple prostatectomy, and prostatic artery embolization were compared.Results:From January 1, 2004 to February 28, 2023, the number of internet search queries have increased for TURP, PUL, Rezum, prostatic artery embolization, and holmium laser enucleation of the prostate. There has been a slight decrease in searches for Greenlight, transurethral needle ablation, transurethral microwave thermotherapy, iTind, simple prostatectomy, and Aquablation.Conclusion:Despite increased searches of alternatives, TURP remains the most searched BPH procedure. Additionally, search habits may be influenced by several factors including government approval, corporate acquisition, and marketing campaigns. It is important for physicians to understand the types of events that may cause patients to inquire about certain treatments for better quality health information and clinical visits.展开更多

Material and Methods: This is a prospective, descriptive, cross-sectional study lasting six (6) months, from July 1, 2022 to December 31, 2022. Patients with BPH on comorbidity condition taken care of during the study period AND have agreed to participate in the study. Results: During our study, 49 cases of benign prostatic hypertrophy with comorbidities were collected, representing a frequency of 29%. The average age ranges for the patients were 43 - 70 years. The age group most affected was 70 to 79 years old (38.80%). Nocturnal urinary frequency was the main reason for consultation present in all our patients. The most frequent comorbidity was hypertension, i.e. 83.70%. The PSA rate between 4 and 10 was the most represented, i.e. 42.86%. The prostate volume was between 61 and 100 ml in 40.82% of patients. Histology showed that it was a benign adenomatous hypertrophy of the prostate in 85.70% and a prostatic adenomyoma in 14.29%. Trans-bladder adenomectomy alone was the most performed technique, i.e. 49%, followed by trans urethral resection of the prostate, i.e. 38.80%. Retention of urine after removal of the catheter was the most observed complication, i.e. 12.20%. Conclusion: Benign prostatic hypertrophy with comorbidities constitutes a frequent association.

文摘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 6 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.
文摘Objective:Thulium fiber laser enucleation of the prostate(ThuFLEP)and robot-assisted simple prostatectomy(RASP)are two options for treating large benign prostatic hyperplasia.The most appropriate technique remains a matter of debate.We evaluated the efficacy and safety of ThuFLEP compared to RASP.Methods:Between January 2020 and December 2023,all patients who underwent either RASP or ThuFLEP for a prostate volume>80 mL were retrospectively included.The surgical procedure choice was left to the surgeon’s and patient’s discretion.Preoperative patient evaluation included the assessment of functional parameters.The groups were compared.Results:A total of 234 patients were included:106(45%)underwent RASP and 128(55%)underwent ThuFLEP.The mean operative time was shorter in the ThuFLEP group compared to the RASP group(106.4 with standard deviation[SD]46.1 min vs.123.2[SD 32.8]min,p=0.012).The mean lengths of catheterization and stay were significantly longer in the RASP group(5.0[SD 3.9]days vs.1.7[SD 2.0]days,p=0.009[catheterization]and 4.9[SD 3.0]days vs.1.9[SD 1.8]days,p=0.009[stay]).The overall complication rate was significantly higher in the ThuFLEP group(12%vs.2.8%in the RASP group,p=0.022).However,we did not observe significant differences in major complications(Clavien-Dindo≥3)between the two groups(four[3.1%]in the ThuFLEP group vs.one[0.94%]in the RASP group,p=0.073).At 3 months,the rate of stress urinary incontinence was 4.7%after ThuFLEP and 1.9%after RASP(p=0.2).Finally,the quality of life score and maximum urinary flow were comparable between the ThuFLEP and RASP groups,but the International Prostate Symptom Score at 3 months postoperatively was lower in the RASP group(p=0.012).Conclusion:Both ThuFLEP and RASP are safe techniques with comparable functional outcomes for large benign prostatic hyperplasia.ThuFLEP allows a reduction in catheterization and hospitalization durations but presents more complications compared to RASP.
文摘Objective:This study aims to investigate the potential molecular mechanism of Salvia miltiorrhiza in treating benign prostatic hyperplasia(BPH)based on network pharmacology.Methods:Active components of Salvia miltiorrhiza were screened via the TCMSP database,and their potential targets were predicted using Swiss Target Prediction.BPH-related targets were obtained from Gene Cards and OMIM databases.Common targets between the herb and BPH were used to con-struct a protein-protein interaction(PPI)network via STRING and visualized using Cytoscape.Core targets were identifi ed,and Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were conducted(P≤0.01).Results:A total of 57 active components and 818 targets of Salvia miltiorrhiza were identifi ed.Intersection analysis yielded 458 potential targets associated with BPH.PPI network analysis revealed core targets including SRC,PIK3R1,and PIK3CA.GO enrichment analysis indicated that the targets were primarily associated with biological processes(BP)such as calcium ion homeostasis,cellular components(CC)including focal adhesions,and molecular functions(MF)such as tyrosine kinase activity.KEGG pathway analysis indicated that Salvia miltiorrhiza may exert therapeutic effects through pathways including MAPK,PI3K-Akt,and calcium signaling(P≤0.01).Conclusion:Salvia miltiorrhiza may regulate BPH through a multi-component,multi-target,and multi-pathway network,providing a theoretical basis for its clinical application.

文摘Background:Benign prostatic hyperplasia(BPH)is the most common disease in elderly men.There is increasing evidence that periodontitis increases the risk of BPH,but the specific mechanism remains unclear.This study aimed to explore the role and mechanism of the key periodontal pathogen Porphyromonas gingivalis(P.gingivalis)in the development of BPH.Methods:The subgingival plaque(Sp)and prostatic fluid(Pf)of patients with BPH concurrent periodontitis were extracted and cultured for 16S r DNA sequencing.Ligature-induced periodontitis,testosterone-induced BPH and the composite models in rats were established.The P.gingivalis and its toxic factor P.gingivalis lipopolysaccharide(P.gLPS)were injected into the ventral lobe of prostate in rats to simulate its colonization of prostate.P.g-LPS was used to construct the prostate cell infection model for mechanism exploration.Results:P.gingivalis,Streptococcus oralis,Capnocytophaga ochracea and other oral pathogens were simultaneously detected in the Sp and Pf of patients with BPH concurrent periodontitis,and the average relative abundance of P.gingivalis was found to be the highest.P.gingivalis was detected in both Sp and Pf in 62.5%of patients.Simultaneous periodontitis and BPH synergistically aggravated prostate histological changes.P.gingivalis and P.gLPS infection could induce obvious hyperplasia of the prostate epithelium and stroma(epithelial thickness was 2.97-fold and 3.08-fold that of control group,respectively),and increase of collagen fibrosis(3.81-fold and 5.02-fold that of control group,respectively).P.gingivalis infection promoted prostate cell proliferation,inhibited apoptosis,and upregulated the expression of inflammatory cytokines interleukin-6(IL-6;4.47-fold),interleukin-6 receptor-α(IL-6Rα;5.74-fold)and glycoprotein 130(gp130;4.47-fold)in prostatic tissue.P.g-LPS could significantly inhibit cell apoptosis,promote mitosis and proliferation of cells.P.g-LPS activates the Akt pathway through IL-6/IL-6Rα/gp130 complex,which destroys the imbalance between proliferation and apoptosis of prostate cells,induces BPH.Conclusion:P.gingivalis was abundant in the Pf of patients with BPH concurrent periodontitis.P.gingivalis infection can promote BPH,which may affect the progression of BPH via inflammation and the Akt signaling pathway.
文摘Benign prostatic hyperplasia(BPH)represents a prevalent etiology of lower urinary tract symptoms(LUTS)in the male population,clinically defined by a nonmalignant proliferation of prostatic tissue.While BPH exhibits a high prevalence among older male populations globally,the precise underlying mechanisms contributing to its development remain incompletely elucidated.Mitochondria,essential organelles within eukaryotic cells,are critical for cellular bioenergetics,the regulation of reactive oxygen species(ROS)generation,and the modulation of cell death pathways.The maintenance of mitochondrial homeostasis involves a complex interplay of processes.By synthesizing previous literature,this review discusses mitochondrial homeostasis in prostate glands and the role of mitochondrial dysfunction in the context of BPH.Furthermore,the review delved into each dimension of mitochondrial dysfunction in the specific etiology of BPH,highlighting its impact on cell survival,apoptosis,ferroptosis,oxidative stress and androgen receptor(AR).Overall,this review aims to unveil the crosstalk between mitochondrial dysfunction and BPH and identify intrinsic mechanisms.

文摘Background:Fibrosis constitutes a significant pathophysiological mechanism in the clinical progression of benign prostatic hyperplasia(BPH)and represents a contributing factor to the ineffectiveness of prevailing pharmacological treatments.Emerging evidence suggests a close association between microbial presence and the development of fibrosis.Nonetheless,the potential involvement of microbes within prostatic tissue in the pathogenesis of BPH and prostatic fibrosis,along with the underlying mechanisms,remains unexplored.Methods:Utilizing immunohistochemistry and microbial sequencing,we analyzed the microbes of prostate tissues from BPH patients with different degrees of prostate fibrosis and found that Salmonellaenterica(S.enterica)was enriched in the high degree of prostate fibrosis.We developed prostate cell and animal models infected with the lipopolysaccharide of S.enterica(S.e-LPS)to assess its impact on prostate fibrosis.To elucidate the underlying functional mechanisms,we employed molecular biology techniques,including RNA degradation assays,N6-methyladenosine(m6A)dot blotting,RNA immunoprecipitation,and m6A immunoprecipitation.Results:Microbial diversity differed between low-and high-fibrosis groups,with S.enterica showing the highest mean abundance among the 4 species that differed significantly.S.e-LPS was detected in S.enterica-rich prostate tissue and was found to significantly promote cell proliferation,cell contractility,lipid peroxidation,and the induction of ferroptosis.Animal experiments demonstrated that S.e-LPS infection led to pronounced hyperplasia of the prostatic epithelium,with epithelial thickness increasing to 1.57 times that of the sham group,and collagen fibrosis increasing to 2.84 times that of the sham group,thereby exacerbating prostatic tissue fibrosis in rats.Invitro experiments further revealed that S.e-LPS promoted prostate cell fibrosis by inducing ferroptosis.Mechanistically,it was determined that S.e-LPS regulates ferroptosis via AlkB homolog 5(ALKBH5)-mediated m6A modification,which affects the stability of glutathione peroxidase 4(GPX4)mRNA,thereby affecting prostatic fibrosis.Conclusion:The findings of this study suggest that S.enterica promotes prostatic fibrosis through ALKBH5-m6A-GPX4-mediated ferroptosis.This research offers novel insights for the development of new therapeutic targets and personalized strategies for the prevention and treatment of BPH from the perspectives of microbes and epigenetics.

文摘Benign prostatic hyperplasia(BPH)is a common condition affecting the quality of life and health status of elderly men.Its incidence increases with age and is often accompanied by symptoms such as urinary frequency,urgency,nocturia,difficulty voiding,and even urinary retention.While conventional Western medicine can alleviate symptoms,it frequently carries risks of side effects and disease recurrence.Traditional Chinese Medicine approaches this condition based on the characteristic patterns observed in the elderly population:predominantly deficiency and blood stasis,with chronic conditions leading to blood stasis.The Yiqi Huoxue method—aimed at tonifying Qi and activating blood circulation—has been shown to improve urinary symptoms,enhance quality of life,and promote overall health in elderly BPH patients.This article explores the application of the Yiqi Huoxue therapeutic principle in managing benign prostatic hyperplasia.
文摘Introduction:Benign prostatic hypertrophy(BPH)is a common condition affecting men later in life,significantly impacting quality of life(QOL).Surgical intervention is often pursued when medicalmanagement fails,but patient satisfaction with outcomes varies.Decisional regret can affect perceived success and patient satisfaction post-surgery.This study evaluates the relationship between post-surgical symptoms and decisional regret across BPH procedures.Methods:A prospective,multicenter cohort study included 54 patients undergoing BPH surgery between March 2023 and February 2024.Patients completed the International Prostate Symptom Score-QOL(IPSSQOL)scale preoperatively and at least three months postoperatively,along with the Decision Regret Scale(DRS).Surgical types included Urolift,Greenlight Laser,Rezum,Aquablation,and transurethral resection of the prostate(TURP).A DRS score of≥25 indicated significant regret.Changes in IPSS-QOL were correlated with DRS scores(Spearman’s rho),and subgroup comparisons were conducted using Mann-Whitney U tests.Results:The average DRS score was 18.3,with 33%of patients reporting a DRS≥25.Moderate correlations existed between quality of life(QOL)change(ρ=0.34,p<0.05)and total regret score.Minimally invasive surgical treatment(MISTs)patients demonstrated higher regret correlations than TURP.Lack of efficacy(75%),new symptoms(41%),and postoperative complications(25%)were the most common reasons for regret.Conclusion:While BPH surgery generally improves symptoms,a substantial portion of patients experience decisional regret.This underscores the importance of preoperative counseling to establish realistic expectations and reduce regret.Further research should explore strategies to enhance shared decision-making and align patient expectations with possible surgical outcomes.

文摘Chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS)is a complex disease that is often accompanied by mental health disorders.However,the potential mechanisms underlying the heterogeneous clinical presentation of CP/CPPS remain uncertain.This study analyzed widely targeted metabolomic data of expressed prostatic secretions(EPS)and plasma to reveal the underlying pathological mechanisms of CP/CPPS.A total of 24 CP/CPPS patients from The Second Nanning People’s Hospital(Nanning,China),and 35 asymptomatic control individuals from First Affiliated Hospital of Guangxi Medical University(Nanning,China)were enrolled.The indicators related to CP/CPPS and psychiatric symptoms were recorded.Differential analysis,coexpression network analysis,and correlation analysis were performed to identify metabolites that were specifically altered in patients and associated with various phenotypes of CP/CPPS.The crucial links between EPS and plasma were further investigated.The metabolomic data of EPS from CP/CPPS patients were significantly different from those from control individuals.Pathway analysis revealed dysregulation of amino acid metabolism,lipid metabolism,and the citrate cycle in EPS.The tryptophan metabolic pathway was found to be the most significantly altered pathway associated with distinct CP/CPPS phenotypes.Moreover,the dysregulation of tryptophan and tyrosine metabolism and elevation of oxidative stress-related metabolites in plasma were found to effectively elucidate the development of depression in CP/CPPS.Overall,metabolomic alterations in the EPS and plasma of patients were primarily associated with oxidative damage,energy metabolism abnormalities,neurological impairment,and immune dysregulation.These alterations may be associated with chronic pain,voiding symptoms,reduced fertility,and depression in CP/CPPS.This study provides a local-global perspective for understanding the pathological mechanisms of CP/CPPS and offers potential diagnostic and therapeutic targets.

文摘BACKGROUND Prostatic artery embolization(PAE)is a promising but also technically demanding interventional radiologic treatment for symptomatic benign prostatic hyperplasia.Many technical challenges in PAE are associated with the complex anatomy of prostatic arteries(PAs)and with the systematic attempts to catheterize the PAs of both pelvic sides.Long procedure times and high radiation doses are often the result of these attempts and are considered significant disadvantages of PAE.The authors hypothesized that,in selected patients,these disadvantages could be mitigated by intentionally embolizing PAs of only one pelvic side.AIM To describe the authors’approach for intentionally unilateral PAE(IU-PAE)and its potential benefits.METHODS This was a single-center retrospective study of patients treated with IU-PAE during a period of 2 years.IU-PAE was applied in patients with opacification of more than half of the contralateral prostatic lobe after angiography of the ipsilateral PA(subgroup A),or with markedly asymmetric prostatic enlargement,with the dominant prostatic lobe occupying at least two thirds of the entire gland(subgroup B).All patients treated with IU-PAE also fulfilled at least one of the following criteria:Severe tortuosity or severe atheromatosis of the pelvic arteries,non-visualization,or visualization of a tiny(<1 mm)contralateral PA on preprocedural computed tomographic angiography.Intraprocedural contrast-enhanced ultrasonography(iCEUS)was applied to monitor prostatic infarction.IU-PAE patients were compared to a control group treated with bilateral PAE.RESULTS IU-PAE was performed in a total 13 patients(subgroup A,n=7;subgroup B,n=6).Dose-area product,fluoroscopy time and operation time in the IU-PAE group(9767.8μGy∙m^(2),30.3 minutes,64.0 minutes,respectively)were significantly shorter(45.4%,35.9%,45.8%respectively,P<0.01)compared to the control group.Clinical and imaging outcomes did not differ significantly between the IU-PAE group and the control group.In the 2 clinical failures of IU-PAE(both in subgroup A),the extent of prostatic infarction(demonstrated by iCEUS)was significantly smaller compared to the rest of the IU-PAE group.CONCLUSION In selected patients,IU-PAE is associated with comparable outcomes,but with lower radiation exposure and a shorter procedure compared to bilateral PAE.iCEUS could facilitate patient selection for IU-PAE.

文摘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.

文摘Panax ginseng(C.A.Mey.)has been traditionally employed in Korea and China to alleviate fatigue and digestive disorders.In particular,Korean red ginseng(KRG),derived from streamed and dried P.ginseng,is known for its anti-aging and anti-inflammatory properties.However,its effects on benign prostatic hyperplasia(BPH),a representative aging-related disease,and the underlying mechanisms remain unclear.This study aims to elucidate the therapeutic effects of KRG on BPH,with a particular focus on mitochondrial dynamics,including fission and fusion processes.The effects of KRG on cell proliferation,apoptosis,and mitochondrial dynamics and morphology were evaluated in a rat model of testosterone propionate(TP)-induced BPH and TP-treated LNCaP cells,with mdivi-1 as a control.The results revealed that KRG treatment reduced the levels of androgen receptors(AR)and prostate-specific antigens in the BPH group.KRG inhibited cell proliferation by downregulating cyclin D and proliferating cell nuclear antigen(PCNA)levels,and it promoted apoptosis by increasing the ratio of B-cell lymphoma protein 2(Bcl-2)-associated X protein(Bax)to Bcl-2 expression.Notably,KRG treatment enhanced the phosphorylation of dynamin-related protein 1(DRP-1,serine 637)compared with that in the BPH group,which inhibited mitochondrial fission and led to mitochondrial elongation.This modulation of mitochondrial dynamics was associated with decreased cell proliferation and increased apoptosis.By dysregulating AR signaling and inhibiting mitochondrial fission through enhanced DRP-1(ser637)phosphorylation,KRG effectively reduced cell proliferation and induced apoptosis.These findings suggest that KRG’s regulation of mitochondrial dynamics offers a promising clinical approach for the treatment of BPH.

文摘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.

文摘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.
文摘Objective:Minimally invasive treatments for benign prostatic hyperplasia (BPH) have seen an increase in usage in recent years. We aimed to determine what types of events may influence patient search habits related to surgical BPH treatments.Methods:Google Trends was used to determine the frequency of searches for different minimally invasive and prostatic ablative treatments for BPH in the United States. The procedures including transurethral resection of the prostate (TURP), Aquablation therapy (Aquablation), Greenlight laser therapy (Greenlight), transurethral needle ablation, transurethral microwave thermotherapy, Urolift (prostatic urethral lift [PUL]), Rezum, iTind, holmium laser enucleation of the prostate, simple prostatectomy, and prostatic artery embolization were compared.Results:From January 1, 2004 to February 28, 2023, the number of internet search queries have increased for TURP, PUL, Rezum, prostatic artery embolization, and holmium laser enucleation of the prostate. There has been a slight decrease in searches for Greenlight, transurethral needle ablation, transurethral microwave thermotherapy, iTind, simple prostatectomy, and Aquablation.Conclusion:Despite increased searches of alternatives, TURP remains the most searched BPH procedure. Additionally, search habits may be influenced by several factors including government approval, corporate acquisition, and marketing campaigns. It is important for physicians to understand the types of events that may cause patients to inquire about certain treatments for better quality health information and clinical visits.
文摘Dear Editor,Prostatic small cell carcinoma(SCC)is a rare,deadly tumor with an overall median survival of fewer than 12 months[1-5].Here we describe a unique case of a patient with prostatic SCC who developed a concurrent tumor thrombus in the right iliac vein.
文摘BACKGROUND Secondary rectal linitis plastica(RLP)from prostatic adenocarcinoma is a rare and poorly understood form of metastatic spread,characterized by a desmoplastic response and concentric rectal wall infiltration with mucosal preservation.This complicates endoscopic diagnosis and can mimic gastrointestinal malignancies.This case series underscores the critical role of magnetic resonance imaging(MRI)in identifying the distinct imaging features of RLP and highlights the importance of considering this condition in the differential diagnosis of patients with a history of prostate cancer.CASE SUMMARY Three patients with secondary RLP due to prostatic adenocarcinoma presented with varied clinical features.The first patient,a 76-year-old man with advanced prostate cancer,had rectal pain and incontinence.MRI showed diffuse prostatic invasion and significant rectal wall thickening with a characteristic"target sign"pattern.The second,a 57-year-old asymptomatic man with elevated prostatespecific antigen levels and a history of prostate cancer exhibited rectoprostatic angle involvement and rectal wall thickening on MRI,with positron emission tomography/computed tomography PSMA confirming the prostatic origin of the metastatic spread.The third patient,an 80-year-old post-radical prostatectomy,presented with refractory constipation.MRI revealed a neoplastic mass infiltrating the rectal wall.In all cases,MRI consistently showed stratified thickening,concentric signal changes,restricted diffusion,and contrast enhancement,which were essential for diagnosing secondary RLP.Biopsies confirmed the prostatic origin of the neoplastic involvement in the rectum.CONCLUSION Recognizing MRI findings of secondary RLP is essential for accurate diagnosis and management in prostate cancer patients.
文摘Goal: To determine the type of comorbidity and highlight the complications of adenomectomy and comorbidities. Material and Methods: This is a prospective, descriptive, cross-sectional study lasting six (6) months, from July 1, 2022 to December 31, 2022. Patients with BPH on comorbidity condition taken care of during the study period AND have agreed to participate in the study. Results: During our study, 49 cases of benign prostatic hypertrophy with comorbidities were collected, representing a frequency of 29%. The average age ranges for the patients were 43 - 70 years. The age group most affected was 70 to 79 years old (38.80%). Nocturnal urinary frequency was the main reason for consultation present in all our patients. The most frequent comorbidity was hypertension, i.e. 83.70%. The PSA rate between 4 and 10 was the most represented, i.e. 42.86%. The prostate volume was between 61 and 100 ml in 40.82% of patients. Histology showed that it was a benign adenomatous hypertrophy of the prostate in 85.70% and a prostatic adenomyoma in 14.29%. Trans-bladder adenomectomy alone was the most performed technique, i.e. 49%, followed by trans urethral resection of the prostate, i.e. 38.80%. Retention of urine after removal of the catheter was the most observed complication, i.e. 12.20%. Conclusion: Benign prostatic hypertrophy with comorbidities constitutes a frequent association. Because their presence can affect effectiveness and lead to complications.
