Incidence and predictors of urinary incontinence rates after thulium fiber laser enucleation of prostate performed by single surgeon.

Purpose: We aimed to evaluate the predictive clinical and operative risk factors for urinary incontinence (UI) rates following thulium fiber enucleation of benign prostate hyperplasia (ThuFLEP). Materials and methods: We conducted a retrospective cohort review of a prospectively maintained database for patients who underwent ThuFLEP between 2021 and 2023 in our university clinic performed by a single surgeon with high experience (more than 3000 endoscopic enucleation). To perform the operation, we used a thulium fiber laser Fiberlase U3 (IRE Polus ltd, Fryazino, Russia) with operating modes of 1.5 J and 40 Hz 60 W. Postoperative UI rates and risk factors following ThuFLEP were assessed for three follow-up intervals (up to 1 months, from 1 to 3 months and after 3 months post-ThuFLEP). Statistical analysis was conducted using univariate and multivariate logistic regression. Results: Out of total 578 patients who underwent ThuFLEP, the study included 381 patients with full information about continence status. Long-term UI (more than 3 months) were found only in 1.6% cases with 0.8% for stress UI, 0.3% for urge UI and 0.5% for mixed UI. Univariate logistic regression analysis has shown that higher total laser energy (OR = 1.009; 95% CI = 1.001-1.018; p = 0.036) and enucleation technique (OR = 0.272; 95% CI = 0.113-0.656; p = 0.004 in favor of En-bloc ThuFLEP) were associated with UI overall, while at multivariable analysis only En-bloc ThuFLEP was protective factor for UI (OR = 0.302; 95%CI = 0.123-0.739; p = 0.009). For short-term UI (less than 1 months) early sphincter release was found as protective factor at both uni- and multivariate analysis compare to longer UI. Conclusion: Short-term UI up to 3 months following ThuFLEP is associated with early sphincter release, while overall UI rates are related with enucleation technique (preferable En-bloc) and total laser energy (preferable lower energy). The surgeon should take all these risk factors into account before choosing the technique of BPH surgical treatment.

Antioxidative, anti-androgenic, and inhibitory activities of ethanolic extract of Annona muricata leaf on sex hormones-induced benign prostate hyperplasia through in vivo and in silico studies.

Benign prostate hyperplasia (BPH) remains one of the major age-related urological problems in the world. Annona muricata (soursop) leaf has been reported to exhibit antiproliferative, antioxidant, and anti-inflammatory activities, among others, in the literature. Here, we aimed to unravel the antioxidative, antiandrogenic, and inhibitory activities of the ethanol extract of Annona muricata leaf (EEAML) on sex hormones-induced benign prostate hyperplasia (BPH) through in vivo and in silico studies. Thirty-six male rats were segmented into six groups of six animals each, the control group received water, and the BPH group and the remaining four groups were parentally infused with testosterone (T) and oestradiol (E2) (0.08 and 0.04 mg/Kgbwt) once daily for 28 days to induce BPH. After that, the control and BPH groups received water and normal saline, while the remaining four groups received finasteride (FIN) (0.1 mg/kgbwt) and EEAML (200, 400, and 800 mg/kgbwt) for another 28 days before sacrifice, and serum was collected for biochemical analysis. Additionally, the active ingredients of EEAML were identified using a Gas Chromatography Flame Ionisation Detector (GC-FID) followed by molecular docking (MD) against the human androgen receptor (hAR) target, and ADMET analysis of selected EEAML compounds was carried out. EEAML (200, 400, and 800 mg/kgbwt) restored the T and E2-induced depletion of reduced glutathione level, superoxide dismutase and catalase activities, and elevation of malondialdehyde, prostate-specific antigen, testosterone, and dihydrotestosterone levels in the serum of BPH rats. GC-FID analysis of EEAML showed the presence of 21 compounds from which 15 compounds were subjected to MD revealing that flavone, followed by ribalinidine, flavonone, anthocyanin, and naringenin displayed desirable binding affinities against the hAR target. ADMET analysis of these top-five EEAML compounds revealed that they were excellent oral bioavailable drug candidates with predicted minimal toxicities. In conclusion, EEAML exhibited antioxidative, antiandrogenic, and inhibitory activities owing to its phytoconstituents, which in turn could serve as drug templates for much better efficacy.

Quality and Educational Value of YouTube Surgical Videos of Transurethral Resection of the Prostate: A Descriptive Cross-Sectional Study.

Introduction The aim of the study is to evaluate the quality and educational value of surgical videos on YouTube (Alphabet Inc., Mountain View, CA) demonstrating transurethral resection of the prostate (TURP). Methods A thorough YouTube search for "TURP" or "transurethral resection of the prostate" was performed. Each video's uploader, content, duration, date of upload, time since upload, views, comments, likes, and dislikes, and Video Power Index (VPI) scores were recorded and evaluated. Video analysis and rating followed the LAParoscopic Surgery Video Educational Guidelines (LAP-VEGaS) recommendations, which constitute nine items with values from 0 (absence) to 2 (complete presence). The guidelines' overall score can be 0 to 18. A higher score is indicative of a better level of educational value. Results There were a total of 43 videos included, 10 (23.3%) of which were academic publications. The average LAP-VEGaS score was 6.58, with 22 (51.2%), 18 (41.8%), and three (7%) videos classified as having low, medium, and high educational quality, respectively. None of the videos satisfied all the requirements outlined in the checklist. There was no statistically significant positive correlation observed between the educational score and the number of views. Conclusion A significant proportion of transurethral resection of the prostate (TURP) videos available on the YouTube platform exhibit limited educational value. Videos frequently lack comprehensive and in-depth descriptions of surgical operations. Those seeking information on TURP should carefully choose which videos to view. It is recommended that academic institutions establish comprehensive criteria aimed at enhancing the educational value of surgical videos on the YouTube platform.

Diterpene glycosides from Fructus Rubi ameliorates benign prostatic hyperplasia in rats through the androgen and TGF-ß/Smad signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Fructus Rubi (FR), a food material with medicinal value, is used in traditional Chinese medicine (TCM) for treatment of various kidney-related problems, such as impotence, spermatorrhea, and frequent urination. It is also frequently used to produce diverse functional foods in China. AIM OF STUDY: The purpose of this research was to assess the therapeutic effects of FR diterpene glycosides on RWPE-1 epithelial cell (RWPE-1), a human normal prostatic epithelial cell, and benign prostate hyperplasia (BPH) rats, both of which had been exposed to dihydrotestosterone (DHT) and testosterone propionate (TP), respectively, and to investigate the mechanism of action. METHODS: Target proteins that could stably bind to certain diterpene glycosides were screened through drug affinity responsive target stability combined with mass spectrometry (DARTS/MS). DHT-induced RWPE-1 cells were used to detect drug activity. TP was subcutaneously injected to induce BPH in rats. The extract of diterpene glycosides from FR (FDS) was orally administered for 28 days. The DHT levels in the serum and prostate tissue of the rats were measured through enzyme-linked immunosorbent assay (ELISA), and to analyze cell proliferation and epithelial-mesenchymal transition (EMT), the protein expression of prostate-specific antigen (PSA), androgen receptor (AR), steroid 5α-reductase type 2 (SRD5A2), proliferating cell nuclear antigen (PCNA), S100 calcium-binding protein A2 (S100A2), transforming growth factor-ß1 (TGF-ß1), E-cadherin, vimentin, and Smad4 was determined through western blotting (WB), immunohistochemistry (IHC), or immunofluorescence (IF). RESULTS: FDS reduced the proliferation of DHT-induced RWPE-1 cells. It also significantly inhibited rat prostate enlargement; decreased DHT levels in the serum and prostate tissue; inhibited the protein expression of AR, PSA, PCNA, S100A2, TGF-ß1, E-cadherin, and Smad4; and increased the protein expression of E-cadherin. CONCLUSION: The present study is the first to report that diterpene glycosides isolated from FR inhibited BPH at the cellular level, regulated the proliferation of prostate cells through the androgen signaling pathway, and prevented EMT in the prostate through the S100A2-mediated TGF-ß/Smad signaling pathway. These results indicate that FDS is a promising multitarget therapy for BPH.

Serum levels of prostate specific antigen, free PSA, [-2]proPSA, fPSA/tPSA ratio, Prostate Health Index, and glycosylation patterns of free PSA in patients with benign prostatic hyperplasia pharmacotherapy.

BACKGROUND: The medication used to treat benign prostate hyperplasia (BPH), a common condition in men over 50 years of age, can alter the levels of biomarkers used in prostate cancer detection. Commonly used medications for BPH include alpha-blockers, 5-alpha reductase inhibitors (5-ARIs), and muscarinic antagonists. We studied the impact of these drugs on total prostate-specific antigen (tPSA), free PSA (fPSA), [-2]proPSA, fPSA/tPSA ratio, and the Prostate Health Index (PHI), as well as novel potential biomarkers in the form of glycan composition of fPSA. PATIENTS AND METHODS: Serum samples were collected from 564 males with BPH, with a mean age of 68.5 years. The samples were used to measure levels of tPSA, fPSA, and [-2]proPSA. The fPSA/tPSA and PHI were then calculated. The glycan composition of fPSA was analyzed using lectin-based glycoprofiling. Pharmacotherapy data was collected from the patients' medical records. RESULTS: Alpha-blocker monotherapy was associated with higher fPSA and fPSA/tPSA ratio, and decreased PHI. Levels of tPSA were not impacted. Alpha-blocker and 5-ARI dual therapy was associated with reduced levels of fPSA, [-2]proPSA, and PHI. Therapy combining alpha-blockers and antimuscarinic agents did not significantly influence biomarker levels apart from an increase in a Maackia amurensis lectin-recognized glycan originating in fPSA. CONCLUSION: BPH pharmacotherapy notably affects prostate cancer biomarkers. Recognizing the impact of pharmacotherapy is crucial for achieving an accurate diagnosis of prostate cancer and for planning treatment.

Bulk mRNA-seq data from wild-type and prostate cancer-developing mice reveal a reprogramming of the estrogen and androgen responses after carcinogenesis.

Sex hormones are necessary for the development and functions of the normal prostate as well as for the initiation and progression of prostate tumors. Indeed, androgens and estrogens can activate their respective nuclear receptors to modulate the expression of multiple genes and pathways in prostate cells. Nevertheless, the androgen and estrogen responses in the normal prostate, and the transcriptomic changes occurring after carcinogenesis, remain poorly understood. Here, wildtype mice and transgenic mice that spontaneously develop prostate cancer (C57BL/6J PB-Cre4+/-;Pten fl/fl) were castrated to ensure hormone deprivation. After three days, animals received injections of testosterone and/or estradiol. After one day, the prostates were harvested, and RNA was purified for sequencing. Sequencing data were then analyzed to study transcriptional modulations following hormonal exposures in normal and tumoral murine prostates. New analyses can be carried out with specific fold-change thresholds for gene expression, or with different pair-wise combinations between conditions (treatments and/or mouse models). Together, the data generated herein are a useful tool to study hormonal transcriptional responses in prostate and prostate cancer biology.

The Assessment of Patient-Reported Outcomes in the Medical Management of Patients With Benign Prostatic Hyperplasia.

Background Benign prostatic hyperplasia (BPH) is a prevalent condition that a large portion of the male population develops with aging, in which the prostate gland enlarges and results in urinary symptoms. Objective The objective of this article is to assess patient-reported outcomes (PRO) of medical management of benign prostate hyperplasia in terms of international prostate symptoms score (IPSS), BPH impact index (BPHII), and treatment satisfaction score (TSS). Methods This descriptive study included 114 patients who received medical management for BPH during the period 5th May 2021 till 30th December 2023, at the Department of Urology, Institute of Kidney Disease Peshawar. Patient-reported outcomes were measured in terms of IPSS, BPHII, and TSS. Readings were recorded at the start of treatment and at three months of treatment and then compared. Data was analyzed using SPSS v.25 (IBM Inc., Armonk, New York). Results The mean age of the patients was 64.33 ± 6.12 years. The mean prostate size was 77.35 ± 12.83 ml. Overall mean pre-treatment and post-treatment IPSS was 24.82 ± 4.90 versus 15.57 ± 5.15, respectively (p-value 0.00). Mean pre-treatment and post-treatment BPHII were 11.98 ± 1.02 and 7.12 ± 2.46, respectively (p-value 0.000). The overall mean treatment satisfaction score was 6.89 ± 1.44. Conclusion Medical management improved symptomatology in BPH patients. This study is a step in the direction of the development of larger and longer-term PRO studies in BPH management.

SGLT2 Inhibitor and Urinary Tract Infection in Men at Risk for Voiding Dysfunction: A VigiBase Analysis.

INTRODUCTION: We investigated the risk of UTIs and complex UTIs associated with SGLT2 (sodium-glucose cotransporter-2) inhibitors in men, emphasizing older men at higher risk for voiding dysfunction. METHODS: Utilizing a pharmacovigilance case-noncase design, we analyzed VigiBase reports from 1967 to 2022 among male patients. VigiBase is a comprehensive global database for drug safety. Disproportionality analysis, which compares the frequency of reported adverse events for specific drugs against other drugs, was conducted using reporting odds ratio (ROR) and empirical Bayes estimator (EBE). Age was stratified at 65 years as a threshold for increased susceptibility to male voiding dysfunctions. Sensitivity analyses were performed to compare SGLT2 inhibitor with other diabetes medications and years 2013 to 2022. RESULTS: There were 484 UTIs (ROR 6.75 [95% CI: 6.17-7.39]; EBE 6.78) and 165 complex UTIs (ROR 8.09 [95% CI: 6.94-9.43]; EBE 8.60). In men under 65, there were 178 UTIs (ROR 6.82 [95% CI: 5.88-7.91]; EBE 6.99) and 65 complex UTIs (ROR 7.30 [95% CI: 5.71-9.32]; EBE 7.90). In men 65 and over, we found 153 UTIs (ROR 5.11 [95% CI: 4.35-5.99]; EBE 5.44) and 59 complex UTIs (ROR 8.79 [95% CI: 6.79-11.37]; EBE 9.60). Sensitivity analyses consistently showed significant signals. CONCLUSIONS: This study suggests an elevated risk for both UTIs and complex UTIs in men taking SGLT2 inhibitors, with a more pronounced risk for complex UTI in older men who may have benign prostatic hyperplasia-related voiding dysfunction. These findings highlight the need for a balanced approach in prescribing SGLT2 inhibitors, particularly in populations potentially more susceptible to UTIs.

Real-world experience with the new pulsed solid-state Thulium: YAG laser (Thulio) for endoscopic enucleation of the prostate.

PURPOSE: The solid-state Thulium laser (Tm: YAG) is a novel alternative to the widely used Holmium laser for endoscopic enucleation of the prostate (EEP) due to its relatively high peak power. The aim of this study was to examine the efficacy and safety of a new pulsed Tm: YAG laser in its first application in humans. METHODS: Data were retrospectively collected for the first 103 patients who underwent EEP with a new pulsed solid-state Tm: YAG laser (Thulio®, Dornier MedTech Systems GmbH, Weßling, Germany). Peri- and postoperative data were assessed. Procedure-specific complications were graded using Clavien-Dindo Classifications (CDC). Patients were interviewed 15 months after the surgery to evaluate functional and long-term outcomes. Statistical analysis was performed with Statistical Package for the Social Sciences (SPSS®). RESULTS: The mean preoperative prostate volume was 105.6 ± 55.0 ml. Median enucleation speed was 4.1 g per minute (range 1.1-9.7). Short-term postoperative complications occurred in 21 patients (20.4%), but no high-grade complications (CDC ≥ IV) were observed. Five patients suffered gross haematuria and required reintervention (CDC IIIb; 4.9%). After 15 months, 76 patients (73.8%) participated in the follow-up interview, where seven patients (9.2%) reported complications, including two reinterventions for urethral strictures (CDC IIIb; 2.6%). Most patients reported an improvement in continence (54.0%) and urine stream (93.4%), but no difference in erectile function (81.6%). No persistent dysuria was reported. Patient satisfaction with the surgery results was very high (96.1%). CONCLUSION: Endoscopic enucleation of the prostate with the new pulsed solid-state Tm: YAG laser is a safe and effective option for surgical BPH treatment.

Syzygium malaccense leaves methanol extract modulate some biochemical and inflammatory markers and prostate histology of testosterone-estradiol valerate induced benign prostatic hyperplasia in rats.

Objective: The effect of Syzygium malaccense methanol leaf extract (SMLE) on some parameters of testosterone-estradiol valerate induced benign prostatic hyperplasia (BPH) in rats was assayed. Materials and Methods: Thirty male albino rats were used and they were grouped as: Control: received 1 mL/kg olive oil (oral and subcutaneous); BPH: received subcutaneously 9 mg/kg dihydrotestosterone (DHT)+0.9 mg/kg estradiol valerate (ESV) and orally 1 ml/kg olive oil; finasteride: received 9 mg/kg of DHT+0.9 mg/kg ESV (subcutaneously) and 5 mg/kg finasteride (orally) and test groups 1 and 2: received 9 mg/kg of DHT+0.9 mg/kg ESV (subcutaneously) and 200 and 400 mg/kg SMLE (orally). The duration of the treatment was 28 days. Results: The BPH group had increased prostatic total proteins, oxidative stress, interleukin 8, tumor necrosis factor-α, prostate weights, serum concentrations of prostate specific antigen, estradiol, follicle stimulating hormone, and C-reactive protein, dyslipidaemia, altered prostate histology and hormonal levels but had no significant change (p>0.05) in haematological indices relative to the control. Finasteride or S. malaccense modulated most of these parameters as corroborated by prostate histology. Acute toxicity study indicated the non-toxicity of SMLE. SMLE showed strong in vitro antioxidant activity which corroborated its in vivo antioxidant activity. Conclusion: The study showed that S. malaccense could be useful in the management of BPH.

Prostate stromal sarcoma mimicking benign prostate hyperplasia: A case report.

INTRODUCTION & OBJECTIVES: Prostate stromal sarcoma is extremely rare and aggressive malignancy accounting for less than 1 % of all type of prostate cancers. It is frequently misdiagnosed from other lower urinary tract symptoms (LUTS) problems. CASE PRESENTATION: We present a case report of 45-year-old male complaining with LUTS problems. Patient also suffers anorexia and weight loss. He was first diagnosed with benign prostate hyperplasia (BPH). Patients had done transurethral resection of prostate (TURP) to alleviate the complaint, but the symptoms worsened and recurred. Histopathological examination findings confirmed prostate stromal sarcoma (T4N0M0). Patient was further examined using MRI and then radical prostatectomy procedure was performed. DISCUSSION: Incidence of prostate stromal sarcoma is very low and most commonly presents with obstructive LUTS symptoms. This could mimic other disease such as BPH or other type of prostate cancer. Therefore, clinicians require a high suspicion in patient with recurrent LUTS. CONCLUSION: Prostate stromal sarcoma diagnosis is a challenging disease entity that necessitates histopathology examination. Timely and accurate diagnosis of prostate stromal sarcoma is needed to achieve better outcome and prognosis for the patients.

A Comparative Study of Histotripsy Parameters for the Treatment of Fibrotic ex-vivo Human Benign Prostatic Hyperplasia Tissue.

Histotripsy is a noninvasive focused ultrasound therapy that mechanically fractionates tissue to create well-defined lesions. In a previous clinical pilot trial to treat benign prostatic hyperplasia (BPH), histotripsy did not result in consistent objective improvements in symptoms, potentially because of the fibrotic and mechanically tough nature of this tissue. In this study, we aimed to identify the dosage required to homogenize BPH tissue by different histotripsy modalities, including boiling histotripsy (BH) and cavitation histotripsy (CH). A method for histotripsy lesion quantification via entropy (HLQE) analysis was developed and utilized to quantify lesion area of the respective treatments. These data were correlated to changes in mechanical stiffness measured by ultrasound shear-wave elastography before and after treatment with each parameter set and dose. Time points corresponding to histologically observed complete lesions were qualitatively evaluated and quantitatively measured. For the BH treatment, complete lesions occurred with >=30s treatment time, with a corresponding maximum reduction in stiffness of -90.9±7.2(s.d.)%. High pulse repetition frequency (PRF) CH achieved a similar reduction to that of BH at 288s (-91.6±6.0(s.d.)%), and low-PRF CH achieved a (-82.1±5.1(s.d.)%) reduction in stiffness at dose >=144s. Receiver operating characteristic curve analysis showed that a >~75% reduction in stiffness positively correlated with complete lesions observed histologically, and can provide an alternative metric to track treatment progression.

New Therapies in Outpatient Pulmonary Medicine.

Newer medications and devices, as well as greater understanding of the benefits and limitations of existing treatments, have led to expanded treatment options for patients with lung disease. Treatment advances have led to improved outcomes for patients with asthma, chronic obstructive pulmonary disease, interstitial lung disease, pulmonary hypertension, and cystic fibrosis. The risks and benefits of available treatments are substantially variable within these heterogeneous disease groups. Defining the role of newer therapies mandates both an understanding of these disorders and overall treatment approaches. This section will review general treatment approaches in addition to focusing on newer therapies for these conditions..

Risk of age-related macular degeneration in men receiving 5α-reductase inhibitors: a population-based cohort study.

BACKGROUND: Recent studies suggest that 5α-reductase inhibitors (5ARIs) for benign prostate hyperplasia (BPH) result in abnormal retinal anatomical alteration. OBJECTIVE: To compare age-related macular degeneration (AMD) incidence in BPH patients receiving 5ARIs or tamsulosin. DESIGN: Retrospective, population-based cohort study using new-user and active-comparator design. SETTING: General population. SUBJECTS: Males with BPH, newly receiving 5ARIs or tamsulosin from 2010 to 2018. METHODS: Data were extracted from Taiwan's National Health Insurance Research Database. We used Cox proportional hazards model with 1:4 propensity score (PS) matching, based on intention-to-treat analysis to determine the risk of incident AMD. Sensitivity analyses included an as-treated approach and weighting-based PS methods. We also separately reported the risks of incident AMD in patients receiving finasteride and dutasteride to determine risk differences among different 5ARIs. RESULTS: We included 13 586 5ARIs users (mean age: 69 years) and 54 344 tamsulosin users (mean age: 68.37 years). After a mean follow-up of 3.7 years, no differences were observed in the risk of incident AMD between 5ARIs and tamsulosin users [hazard ratio (HR): 1.06; 95% confidence intervals (95% CI): 0.98-1.15], with similar results from sensitivity analyses. However, increased risk of incident age-related macular degeneration was observed in patients receiving dutasteride [HR: 1.13; 95% CI: 1.02-1.25], but not in those receiving finasteride [HR: 0.99; 95% CI: 0.87-1.12], in the subgroup analyses. CONCLUSIONS: We found no difference between 5ARIs and tamsulosin regarding the incidence of AMD in BPH patients. However, the risk profiles for AMD differed slightly between dutasteride and finasteride, suggesting that the potency of androgen inhibition is a factor related to AMD incidence.

[Establishment of a predictive scoring model and preventive measures for bladder neck contracture after laparoscopic enucleation of the prostate with urethra preservation].

OBJECTIVE: To establish a predictive scoring model for bladder neck contracture (BNC) after laparoscopic enucleation of the prostate with preservation of the urethra (Madigan surgery) and explore the preventive measures against this postoperative complication. METHODS: We included 362 cases of BPH treated by laparoscopic Madigan surgery from January 2019 to March 2022 (45 with and 317 without postoperative BNC) in the training group and another 120 cases treated the same way in the verification group, collected the clinical data on the patients and evaluated the results of surgery. Using the least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression, we analyzed the risk factors for postoperative BNC and constructed a predictive scoring model for evaluation of the factors. RESULTS: Compared with the baseline, the IPSS, quality of life (QOL) score and postvoid residual urine volume (PVR) were significantly decreased (P < 0.05) while the maximum urinary flow rate (Qmax) remarkably increased (P < 0.05) in the BPH patients at 3 months after surgery. Eight non-zero characteristic predictors were identified by LASSO regression analysis. Multivariate logistic regression analysis showed that short clinical experience of the surgeon, concurrent prostatitis, bladder rinse solution temperature <34℃, catheter blockage, urethral balloon injection volume >40 ml and postoperative constipation were independent risk factors for postoperative BNC (P < 0.05). The best cut-off value was 2.36 points in both the training and the verification groups. The results of evaluation exhibited a high discriminability of the predictive scoring model. CONCLUSION: Laparoscopic Madigan surgery is a safe and effective method for the treatment of BPH. Short clinical experience of the surgeon, concurrent prostatitis, bladder rinse solution temperature <34℃, catheter blockage, water injected into the urethral balloon >40 ml and postoperative constipation were independent risk factors for postoperative BNC. The predictive scoring model constructed in this study has a good discriminability and is simple and feasible, contributive to the prediction of postoperative BNC in BPH patients undergoing laparoscopic Madigan surgery.

The GG genotype of rs743572 in CYP17A1 gene regulating the decrease of T/E ratio can be an independent risk factor for MetS-BPH: a retrospective cohort study.

PURPOSE: To confirm if the CYP17A1 gene regulates the ratio of T/E leading to MetS-BPH. METHODS: 824 men, aged 47-88 years, were recruited into this study through consecutive routine physical examination programs and long-term outpatient screening. Several parameters, including SNPs of CYP17A1 gene, total testosterone, estradiol, and the ratio of total testosterone to estradiol (T/E) were obtained for each participant. Based on the diagnosis of BPH, MetS, and MetS-BPH, the participants were divided into BPH and non-BPH groups, MetS and non-MetS groups, and MetS-BPH and non-MetS-BPH groups. Values of the obtained parameters were evaluated using one-way analysis of variance, Student's t-test, Chi-squared test, and logistic regression analysis. RESULTS: SNPs of the CYP17A1 gene, including the rs743572 genotypes (GG, GA, and AA), rs3781287 genotypes (GG, GT, TT), and rs4919686 genotypes (CC, CA, and AA), were present in every group. Only the GG genotype of rs743572 was independently associated with BPH (OR = 5.868, 95% CI: 3.363-7.974, P < 0.001), MetS (OR = 7.228, 95% CI: 3.925-11.331, P < 0.001), and MetS-BPH (OR = 3.417, 95% CI: 1.783-5.266, P < 0.001) after adjusting for age. In the population of genotype GG of rs743572, the decrease in T/E ratio was an independent risk factor for BPH (OR = 839.756, 95% CI: 36.978-1334.263, P = 0.001), MetS (OR = 376.988, 95% CI: 12.980-488.976, P < 0.003), and MetS-BPH (OR = 388.236, 95% CI: 24.869-495.363, P = 0.003). CONCLUSION: The GG genotype of rs743572 in CYP17A1 gene regulating the decrease of T/E ratio can be an independent risk factor for MetS-BPH populations.

Transradial Prostatic Artery Embolization as a Salvage Procedure in a Patient With Severe Deformities and Refractory Hematuria of Prostatic Origin.

Benign prostatic hyperplasia is a common condition causing urinary symptoms in older men. It can sometimes lead to hematuria of prostatic origin, due to increased vascularity of the enlarged gland. If this type of hematuria is severe and refractory to conservative measures, it can be life-threatening. Prostatic artery embolization (PAE) serves as a minimally invasive alternative to traditional surgical interventions, particularly in patients with comorbidities and contraindications to surgery. We present a case of a 79-year-old male with refractory hematuria of prostatic origin (RHPO), multiple comorbidities, and significant deformities of the left upper and both lower limbs. The patient was treated with PAE via the right radial artery, a less common approach in interventional radiology. The procedure was successful and led to a complete resolution of hematuria, with no complications. This report highlights the importance of adapting treatment for complex patients and shows that PAE can be safe and effective in such cases.

Robotic bladder diverticulectomy with concurrent management of bladder outlet obstruction: A choice to consider.

INTRODUCTION: Acquired bladder diverticula (BD) are associated with bladder outlet obstruction. The aim of our study is to analyse the improvement in lower urinary tract symptoms (LUTS) in patients who underwent robot-assisted bladder diverticulectomy (RABD) combined with transurethral prostatectomy (TURP). MATERIAL AND METHODS: A prospectively single-centre, single surgeon cohort of four patients with posterolateral BD due to bladder outlet obstruction (BOO) undergoing RABD combined with TURP between 2018 and 2023 was analysed. RESULTS: Median age and maximum BD diameter were 73.5 years and 16 cm, respectively. All patients had severe LUTS and elevated postvoid residual (PVR). Preliminary uroflowmetry revealed bladder outlet obstruction with a median of maximum urine flow rate of 8.5 ml/s. The median operative time and blood loss were 212 min and 100 ml, respectively. No intraoperative complications were recorded. The median length of stay was 4 days. The International Prostate Symptom Score (IPSS) and PVR were compared between baseline, 1 month and 6 months after surgery. IPSS significantly decreased from 24 (IQR 24-25) preoperatively compared to the postoperative, at 1 month follow up 7 (IQR 6-8) (p < 0.0001). PVR significantly decreased too from 165 (IQR 150-187) to 35 ml (IQR 25-42) (p < 0.0001). In transitioning from the 1-month follow-up to the 6-month follow-up, no substantial statistical improvement was observed. CONCLUSION: Concomitant performance of TURP with RABD is feasible and safe. Diverticulectomy in addiction at the endoscopic procedure should be discussed with patients who have obstructive lower urinary tract symptoms as viable alternative to single procedure individually performed.

Exploring pharmacological interventions in benign prostate hyperplasia: the role of cost-effectiveness analysis in daily practice and future directions.

INTRODUCTION: Benign Prostate Hyperplasia (BPH) significantly impacts men's health and quality of life, with its prevalence rising with age. This review critically examines the cost-effectiveness of pharmacological interventions for BPH to optimize patient outcomes and healthcare resource utilization. AREAS COVERED: This review explores the integration of cost-effectiveness analysis (CEA) into clinical practice, balancing clinical efficacy with economic efficiency in BPH management. We performed a critical literature search, including recent studies on the economic evaluation of BPH treatments, focusing on pharmacotherapies such as alpha-blockers and 5-alpha reductase inhibitors. Additionally, we discussed the concept of CEA and evaluated the role of medicinal reconciliation and the avoidance of polypharmacy in favor of optimal BPH treatment. EXPERT OPINION: Cost-effectiveness analysis is crucial for evaluating BPH treatments, with evidence suggesting a shift towards surgical interventions may offer greater long-term economic benefits. However, these models must be applied cautiously, considering clinical evidence and patient preferences to ensure equitable and patient-centric healthcare.
