JOURNAL OF ETHNOPHARMACOLOGY 2024; 330:118207. [PMID: 38636573 DOI: 10.1016/j.jep.2024.118207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 04/12/2024] [Accepted: 04/14/2024] [Indexed: 04/20/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Benign prostatic hyperplasia (BPH), characterized by prostate enlargement due to cell proliferation, is a common urinary disorder in men over 50, manifesting as lower urinary tract symptoms (LUTS). Currently, several therapeutic options are accessible for treating BPH, including medication therapy, surgery and watchful waiting. Conventional drugs such as finasteride and dutasteride are used as 5α-reductase inhibitors for the treatment of BPH. However long-term use of these drugs is restricted due to their unpleasant side effects. Despite the range of available medical therapies, the effective treatment against BPH is still inadequate. Certain therapeutic plants and their phytochemicals have the aforementioned goals and work by regulating this enzyme. AIM OF THE STUDY This review aims to provide a comprehensive insight to advancements in diagnosis of BPH, modern treatment methods and the significance of ethnobotanically relevant medicinal plants as alternative therapeutics for managing BPH. MATERIAL AND METHODS A thorough and systematic literature search was performed using electronic databases and search engines such as PubMed, Web of Science, NCBI and SciFinder till October 2023. Specific keywords such as "benign prostatic hyperplasia", "medicinal plants", "phytochemicals", "pharmacology", "synergy", "ethnobotany", "5-alpha reductase", "alpha blocker" and "toxicology". By include these keywords, a thorough investigation of pertinent papers was assured, and important data about the many facets of BPH could be retrieved. RESULTS After conducting the above investigation, 104 herbal remedies were found to inhibit Phosphodiesterase-5 (PDE-5) inhibition, alpha-blockers, or 5α -reductase inhibition effects which are supported by in vitro, in vivo and clinical trial studies evidence. Of these, 89 plants have ethnobotanical significance as alpha-blockers, alpha-reductase inhibition, or PDE-5 inhibition, and the other fifteen plants were chosen based on their ability to reduce BPH risk factors. Several phytocompounds, including, rutaecarpine, vaccarin, rutin, kaempferol, β-sitosterol, quercetin, dicaffeoylquinic acid, rutaevin, and phytosterol-F have been reported to be useful for the management of BPH. The use of combination therapy offers a strong approach to treating long-term conditions compare to single plant extract drugs. Furthermore, several botanical combinations such as lycopene and curcumin, pumpkin seed oil and saw palmetto oil, combinations of extracts from Funtumia africana (Benth.) Stapf and Abutilon mauritianum (Jacq.) Medik., and Hypselodelphys poggeana (K.Schum.) Milne-Redh. and Spermacoce radiata (DC.) Sieber ex Hiern are also supported through in vitro and in vivo studies for managing BPH through recuperation in patients with chronic long-term illnesses, as measured by the International Prostate Symptom Score. CONCLUSION The review proposes and endorses careful utilization of conventional medications that may be investigated further to discover possible PDE-5, 5 alpha-reductase, an alpha-blocker inhibitor for managing BPH. Even though most conventional formulations, such as 5 alpha-reductase, are readily available, systemic assessment of the effectiveness and mechanism of action of the herbal constituents is still necessary to identify novel chemical moieties that can be further developed for maximum efficacy. However, there exist abundant botanicals and medicinal plants across several regions of Africa, Asia, and the Americas, which can be further studied and developed for utilization as a potential phytotherapeutic for the management of BPH.

Abstract
OBJECTIVE To assess the re-intervention rates of new surgical benign prostatic hyperplasia (BPH) interventions, as the clinical durability of new surgical interventions for BPH is not widely known. METHODS A critical review of new surgical BPH therapies namely 'UroLift®', 'Aquablation', 'Rezum', 'prostatic artery embolisation (PAE)' and 'temporary implantable nitinol device (iTIND)' was performed on PubMed, the Cochrane Library, and Embase databases between May 2010 and December 2022 according to the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement. All relevant articles were reviewed, and the risk of bias was evaluated using the Cochrane risk assessment tool and Newcastle-Ottawa Scale. RESULTS Of the 32 studies included, there were 10 randomised controlled trials and 22 prospective observational cohorts. A total of 2400 participants were studied with a median patient age of 66 years, a median prostate volume of 51.9 mL, and a median International Prostate Symptom Score of 22. The lowest re-intervention rate at 12 months was for Aquablation at 0.01%, followed by Rezum at 0.02%, iTIND at 0.03%, and PAE at 0.05%. Network meta-analysis (NMA) showed that the best-ranked treatment at 12 months was transurethral resection of the prostate (TURP), followed by Aquablation, iTIND, Rezum, and UroLift. Re-intervention rates with these new BPH interventions are comparable, although some interventions reported better outcomes than TURP in the shorter term. CONCLUSIONS While this systematic review and NMA showed that the re-intervention rate with these new surgical BPH interventions appears to be comparable to TURP in the short term, further studies are required to directly compare these various BPH procedures.

Abstract
RATIONALE AND OBJECTIVES This retrospective study evaluates the efficacy and safety of Prostatic Artery Embolization (PAE) for the treatment of benign prostatic hyperplasia (BPH) over five years at a single center, conducted by an experienced interventional radiologist. MATERIALS AND METHODS We analyzed 551 PAE interventions from January 2019 to July 2023. Key metrics included patient demographics, procedural details (radiation exposure, particle size), complication rates, pre- and post-interventional prostatic volume (PV), Prostate-specific Antigen (PSA) levels, International Prostate Symptom Score (IPSS), Quality of Life (QoL) scores and International Index of Erectile Function (IIEF) scores. We assessed data normality, performed group and paired sample comparisons, and evaluated correlations. RESULTS For 551 men, the average patient age was 68.81 ± 8.61 years undergoing bilateral embolization. The particle size predominantly used was 100-300 µm (n = 441). PAE lead to significant (p < .001) reduction of both PV (-9.67 ± 14.52 mL) and PSA level (-2,65 ± 1.56 ng/mL) between pre- and three months after PAE. Substantial improvement were observed for IPSS (-9 points) and QoL scores (-2 points), with stable IIEF scores. Only minor complications (n = 16) were reported, and no major complications were observed. Between the first PAE in 2019 and the routinely performed PAE in 2023 significant (p < .0001) reductions in fluoroscopy (-25.2%), and procedural times (-26.1%) were observed. CONCLUSION In conclusion, PAE is a safe and effective treatment for BPH, offering significant improvements in lower urinary tract symptoms (LUTS) and QoL while maintaining sexual function.

Abstract
ABSTRACT The increasing importance of treatment of lower urinary tract symptoms (LUTS), while avoiding side effects and maintaining sexual function, has allowed for the development of minimally invasive surgical therapies (MISTs). Recently, the European Association of Urology guidelines reported a paradigm shift from the management of benign prostatic hyperplasia (BPH) to the management of nonneurogenic male LUTS. The aim of the present review was to evaluate the efficacy and safety of the most commonly used MISTs: ablative techniques such as aquablation, prostatic artery embolization, water vapor energy, and transperineal prostate laser ablation, and nonablative techniques such as prostatic urethral lift and temporarily implanted nitinol device (iTIND). MISTs are becoming a new promise, even if clinical trials with longer follow-up are still lacking. Most of them are still under investigation and, to date, only a few options have been given as a recommendation for use. They cannot be considered as standard of care and are not suitable for all patients. Advantages and disadvantages should be underlined, without forgetting our objective: treatment of LUTS and re-treatment avoidance.

A correlation study between prostate necrosis rate calculated by 3D Slicer software and clinical efficacy of prostatic artery embolization, along with an analysis of predictors of clinical success after prostatic artery embolization. Abdom Radiol (NY) 2024; 49:927-938. [PMID: 38158423 DOI: 10.1007/s00261-023-04131-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 11/08/2023] [Accepted: 11/12/2023] [Indexed: 01/03/2024]
Abstract
PURPOSE To analyze the correlation between the prostate necrosis rate at 1-month after prostatic artery embolization (PAE) and the clinical efficacy at 1-year after PAE, and to explore potential predictors of clinical success after PAE for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH). METHODS The prostate magnetic resonance imaging data at 1-month after PAE were imported into 3D Slicer software for calculating the prostate necrosis rate and thus analyzing the relationship between the prostate necrosis rate at 1-month after PAE and the efficacy score ratio at 1-year after PAE. The 151 patients with PAE technical success were divided into a clinical success group (n = 126) and a clinical failure group (n = 25). Independent predictors of clinical success after PAE were analyzed by multifactorial logistic regression, and the predictive performance of each factor was evaluated by applying the receiver operating characteristic curve and the area under the curve (AUC). RESULTS There was a linear negative correlation between the prostate necrosis rate at 1-month after PAE and the efficacy score ratio at 1-year after surgery (P < 0.001). In the clinical success group, both the initial prostate volume (PV) and the prostate necrosis rate at 1-month after PAE were significantly higher than in the clinical failure group (P < 0.001), and acute urinary retention (AUR) and adenomatous-dominant BPH were also associated with clinical success (P < 0.05). Multifactorial logistic regression analysis revealed that larger initial PV, a higher prostate necrosis rate at 1-month after surgery, and AUR were independent predictors of clinical success after PAE. The AUC values for these three indicators and their combination were 0.720, 0.928, 0.599, and 0.951, respectively, in which the prostate necrosis rate at 1-month after PAE demonstrating a high predictive value. CONCLUSION The higher the prostate necrosis rate at 1-month after PAE, the better the clinical efficacy at 1-year after PAE is likely to be, and the prostate necrosis rate at 1-month after PAE is expected to become a predictor of clinical success after PAE.

Abstract
Abstract
Benign prostatic hyperplasia (BPH) is a common disease associated with lower urinary tract symptoms and the most frequent benign tumor in men. To reduce BPH therapy complications, prostatic artery embolization (PAE) was developed to replace the surgical options. PAE is a minimally invasive technique in which emboli are injected into the prostate arteries (PA), obstructing the blood flow in the hypervascular nodules. In this work, a personalized PAE treatment strategy was proposed using patient-specific computational fluid dynamics (CFD). First, the hemodynamics environment in the iliac arterial tree considering a large network of bifurcations was studied. The results showed complex blood flow patterns in the iliac arterial network. Subsequently, the transport of embolic particulates during PAE for the standard horizontal and a hypothetical vertical patient positioning was simulated using Lagrangian particle tracking. Emboli with different sizes were released at various locations across the iliac arterial tree. The emboli entering the PA were mapped back to their initial location to create emboli release maps (ERMs). The obtained ERMs during the standard patient positioning for smaller emboli at certain release locations showed distinct regions in which if the emboli were released within these regions, all of them would reach the PA without non-target embolization. During the hypothetical vertical patient positioning, the larger emboli formed a larger coherent region in the ERMs. Our patient-specific model can be used to find the best spatial location for emboli injection and perform the embolization procedure with minimal off-target delivery.

Abstract
PURPOSE The aim of this study was to investigate whether prostatic artery embolization (PAE) can be considered a long-term cost-effective treatment option in patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia in comparison to transurethral resection of the prostate (TURP). METHODS The in-hospital costs of PAE and TURP in the United States were obtained from a recent cost analysis. Clinical outcomes including nature and rate of adverse events for TURP and PAE along with rates of retreatment because of complications or clinical failure were obtained from peer-reviewed literature. A decision tree-based Markov model was created, analyzing long-term cost-effectiveness for TURP and PAE from a US health care sector perspective. Cost-effectiveness over a time frame of 5 years was estimated while assuming a willingness to pay of $50,000 per quality-adjusted life-year (QALY). The primary outcome was incremental cost-effectiveness ratio. RESULTS PAE resulted in overall cost of $6,464.92 and an expected outcome of 4.566 QALYs. In comparison, TURP cost $9,221.09 and resulted in expected outcome of 4.577 QALYs per treatment. The incremental cost-effectiveness ratio for TURP was $247,732.65 per QALY. On the basis of the willingness-to-pay threshold, PAE is cost effective compared with TURP. CONCLUSIONS On the basis of our model, PAE in comparison with TURP can be regarded as a cost-effective treatment option for patients with lower urinary tract symptoms within the US health care system.

Material and methods This retrospective study included 11 cases of PAE and subsequent RASP, performed on 11 patients with BPH from March 2018 to September 2020. Clinical information on the patients was collected before surgery and 3 months after surgery. For the quantification of lower urinary tract symptoms (LUTS), International Prostate Symptom Scores (IPSSs), prostate-specific antigen (PSA) levels, urinary peak flow rate (Qmax), voided volume (Vvol), and postvoid residual volume (PVR) were measured. Results PAE and the subsequent RASP were successfully performed in all 11 patients. The mean total prostate volume was 129.7 ± 65.1 mL, and the transitional zone volume was 71.7 ± 5.9 mL. The mean resected prostate volume was 60.8 ± 26.1 mL. The mean hemoglobin level of the patients prior to PAE was 14.2 ± 2.3 g/dL, and one day after RASP, the hemoglobin level was 12.4 ± 1.9 g/dL. The outcome indicated that there was a considerable decline in IPSS and PVR after RASP was performed compared to before PAE (21.6 ± 9.4 vs. 10.6 ± 8.0 and 159.4 ± 145.8 mL vs. 43.9 ± 45.9 mL). Qmax and Vvol significantly improved after RASP was performed (7.6 ± 5.2 mL/s vs. 26.1 ± 12.6 mL/s; 114.2 ± 92.5 mL vs. 192.4 ± 91.8 mL, respectively). Conclusion This research demonstrated that RASP could be performed safely and effectively after PAE in patients with large BPH.

Prostatic artery embolization in people with spinal cord injury: a safe and effective technique to ease intermittent catheterization in case of concomitant benign prostatic hyperplasia. Spinal Cord Ser Cases 2022; 8:34. [PMID: 35332117 PMCID: PMC8948271 DOI: 10.1038/s41394-022-00499-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 02/18/2022] [Accepted: 02/20/2022] [Indexed: 11/09/2022] Open
Abstract
STUDY DESIGN Case series. OBJECTIVES To assess the safety and efficacy of prostatic artery embolization (PAE) to reduce prostate volume (PV) and facilitate intermittent catheterization (IC) in individuals with concurrent benign prostatic hyperplasia (BPH) and spinal cord injury (SCI). SETTING Italian tertiary referral center for people with SCI. METHODS We retrospectively collected all data of individuals undergoing PAE from 2015 to 2020 because of BPH-related problems during IC. PAE was performed under local anesthesia with superselective catheterization of the prostatic arteries. Technical success was defined as bilateral embolization. We determined pre- and post-procedural PV by magnetic resonance imaging. RESULTS We considered 10 cases with tetraplegia (n = 5) and paraplegia (n = 5). Nine (90%) procedures were technically successful, while we performed monolateral PAE in one case. The median pre-procedural PV was 61 mL. After 6 months, all patients experienced significant PV reduction (median: 19.6%), and 7/7 patients with indwelling urinary catheter started successfully IC. Neither intra- nor post-procedural complications occurred within a median follow-up of 33 months. CONCLUSIONS PAE proved to be a safe and effective treatment for BPH to facilitate IC in people with SCI. Considering the minimal morbidity of PAE, further multi-center studies are mandatory to draw definitive conclusions and warrant its widespread adoption in this population.

Abstract
Background Benign prostatic hyperplasia (BPH) is associated with severe lower urinary tract symptoms (LUTS). The severity of LUTS is assessed by the International Prostate Symptoms Score (IPSS). Prostate artery embolisation (PAE) is a newly available method for combating LUTS. This study aims to assess the outcomes of PAE in reducing LUTS and prostate volume in patients with BPH. Methods Patients diagnosed with BPH with severe LUTS who had undergone PAE were included. Their IPSS score was ≥ 20 despite medical therapy. PAE was performed via the unilateral femoral artery using various types of embolic material. Bilateral or unilateral embolisation of the prostate artery was considered a technical success. The severity of LUTS pre- and post-PAE were assessed using IPSS while prostate volume pre- and post-PAE were assessed by ultrasound and magnetic resonance imaging (MRI). Results Ninety percent of patients had technical success and one required transurethral resection of the prostate (TURP). The mean IPSS reduction at the final follow-up was 12.9 (P < 0.028). The mean reduction of prostate volume at the last follow-up by ultrasound was 114.99 mL (P < 0.028) and by MRI was 29.17 mL (P < 0.028). Conclusion PAE is safe and effective in reducing severe LUTS and prostate gland volume in BPH patients.

Retrospective observation of the efficacy and safety of prostatic artery embolization combined with transurethral resection of the prostate and simple transurethral resection of the prostate in the treatment of large (> 100 mL) benign prostatic hyperplasia. Abdom Radiol (NY) 2021; 46:5746-5757. [PMID: 34448024 DOI: 10.1007/s00261-021-03258-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 08/17/2021] [Accepted: 08/18/2021] [Indexed: 12/13/2022]
Abstract
PURPOSE To retrospectively compare the efficacy and safety of prostatic artery embolization (PAE) combined with transurethral resection of the prostate (TURP) and simple TURP in treating large (> 100 mL) benign prostatic hyperplasia (BPH). METHODS We retrospectively analyzed the clinical data of 13 and 17 patients with large BPH who underwent TURP and PAE + TURP, respectively, from January 2016 to January 2020. The changes in various indices before and after surgery were compared between the two groups. RESULTS In the PAE + TURP group, the operation time (OT), intraoperative blood loss (BL), postoperative bladder flushing time (PBFT), and postoperative catheter retention time (PCRT) were lower, and the speed of the excised lesion (SEL) was higher than that in the TURP group (P < 0.05). Following-up for 12 months, the prostatic volume (PV), maximum urinary flow rate (Qmax), postvoid residual volume (PVR), International Prostate Symptom Score (IPSS), quality of life (QoL) score, total prostate-specific antigen (T-PSA), and free prostate-specific antigen (F-PSA) in each group improved as compared to before the surgery (P < 0.05), and the above improved indicators, IPSS ratio, and obstructive symptoms in the PAE + TURP group were higher than those in the TURP group (P < 0.05). The incidence of postoperative complications in the PAE + TURP group was lower than that in the TURP group. We obtained the pathological picture of a prostate biopsy after PAE for the first time. CONCLUSION Compared to TURP alone, PAE + TURP should be promoted, because of its greater efficacy and safety in treating large BPH and fewer post-surgical complications.

Abstract
Context Benign prostatic hyperplasia (BPH) associated with lower urinary tract symptoms (LUTS) is diagnosed in up to 80% of men during their lifetime. Several novel ultra-minimally invasive surgical treatments (uMISTs) for BPH/benign prostatic obstruction (BPO) have become available over the past 5 yr. Objective To evaluate the perioperative and functional outcomes of recently introduced uMISTs for BPH/BPO, including Urolift, Rezūm, temporary implantable nitinol device, prostatic artery embolization (PAE), and intraprostatic injection. Evidence acquisition A systematic literature search was conducted in December 2020 using Medline (via PubMed), Embase (via Ovid), Scopus, and Web of Science (registered on PROSPERO as CRD42021225014). The search strategy used PICO criteria and article selection was conducted in accordance with the PRISMA guidelines. The risk of bias and the quality of the articles included were assessed. A dedicated data extraction form was used to collect the data of interest. Pooled and cumulative analyses were performed to compare perioperative and functional outcomes between study groups. A random-effects model using the DerSimonian and Laird method was used to evaluate heterogeneity. Stata version 15.0 software was used for all statistical analyses. Evidence synthesis The initial electronic search identified 3978 papers, of which 48 ultimately met the inclusion criteria and were included in the analysis. Pooled analysis revealed a uMIST benefit in terms of International Prostate Symptom Score (IPSS; −9.81 points, 95% confidence interval [CI] −11.37 to −8.25 at 1 mo; −13.13 points, 95% CI −14.98 to −11.64 at 12 mo), maximum flow rate (from +3.66 ml/s, 95% CI 2.8–4.5 to +4.14 ml/s, 95% CI 0.72–7.56 at 12 mo), and postvoid residual volume (−10.10 ml, 95% CI −27.90 to 7.71 at 12 mo). No negative impact was observed on scores for the International Index of Erectile Function-5, Male Sexual Health Questionnaire-Ejaculatory Dysfunction bother and function scales (overall postintervention change in pooled median score of 1.88, 95% CI 1.34–2.42 at the start of follow-up; and 1.04, 95% CI 0.28–1.8 after 1 yr), or the IPSS-Quality of Life questionnaire. Conclusions Novel uMISTs can yield fast and effective relief of LUTS without affecting patient quality of life. Only Rezūm, UroLift, and PAE had a minimal impact on patients’ sexual function with respect to baseline, especially regarding preservation of ejaculation. Patient summary We reviewed outcomes for recently introduced ultra-minimally invasive surgical treatments for patients with lower urinary tract symptoms caused by benign prostate enlargement or obstruction. The evidence suggests that these novel techniques are beneficial in terms of controlling symptoms while preserving sexual function. Take Home Message Novel ultra-minimally invasive treatments can yield fast and effective relief of lower urinary tract symptoms without affecting a patient’s quality of life.

Abstract
OBJECTIVE The purpose of this review was to summarize the current literature on the assessment and treatment of radiation urethritis and cystitis (RUC) for the development of an evidenced-based management algorithm. MATERIAL AND METHODS The PubMed/MEDLINE database was searched by a multidisciplinary group of experts in January 2021. RESULTS In total, 48 publications were identified. Three different types of RUC can be observed in clinical practice: inflammation-predominant, bleeding-predominant, and the combination of inflammation- and bleeding-RUC. There is no consensus on the optimal treatment of RUC. Inflammation-predominant RUC should be treated symptomatically based on the existence of bothersome storage or voiding lower urinary tract symptom as well as on pain. When bleeding-predominant RUC has occurred, hydration and hyperbaric oxygen therapy (HOT) should be used first and, if HOT is not available, oral drugs instead (sodium pentosane polysulfate, aminocaproic acid, immunokine WF 10, conjugated estrogene, or pentoxifylline + vitamin E). If local bleeding persists, focal therapy of bleeding vessels with a laser or electrocoagulation is indicated. In case of generalized bleeding, intravesical installation should be initiated (formalin, aluminium salts, and hyaluronic acid/chondroitin). Vessel embolization is a less invasive treatment with potentially less complications and good clinical outcomes. Open- or robot-assisted surgery is indicated in patients with permanent, life-threatening bleeding, or fistulae. CONCLUSIONS Treatment of RUC, if not self-limiting, should be done according to the type of RUC and in a stepwise approach. Conservative/medical treatment (oral and topic agents) should primarily be used before invasive (transurethral) treatments.

Abstract
Benign prostatic hyperplasia (BPH) is one of the most common diseases of the
genitourinary system. The prevalence of BPH increases in men with advancing age.
While transurethral resection of the prostate gland entails complications such
as retrograde ejaculation, urinary incontinence, hematuria, urethral strictures,
bladder neck sclerosis, and other adverse events, it is necessary to apply
minimally invasive surgical methods such as superselective embolization of the
prostatic arteries (PAE), particularly Proximal Embolization First Then Distal
Embolization (PErFecTED). The data from 1,015 BPH patients who underwent
endovascular surgery demonstrate the benefits of PErFecTED treatment during 24
months after surgery. Both Quality of Life score and International Prostate
Symptom Score were around three times better in the PErFecTED group and remained
stable during the entire observation period. However, the technique needs to be
improved due to the high risk of postembolization syndrome.

Abstract
PURPOSE To investigate the safety and effectiveness of superselective prostatic artery embolization (PAE) in patients with benign prostatic hyperplasia (BPH). METHODS Sixty-five patients diagnosed with BPH in Fujian Provincial Hospital between December 2014 and July 2019 were included. Patients with ineffective drug treatment after 6 months, who refused surgery, or who were unsuitable for surgery were included. We observed postoperative complications, followed up at 1, 3, and 6 months, compared clinical symptoms, and monitored changes in prostate-specific antigen (PSA) and prostatic volume (PV) before and after treatment. RESULTS Of the 65 patients, 58 (89.23%) successfully received PAE; 44 and 14 bilateral and unilateral embolization, respectively. Clinical efficacy was 94.83% (55/58) after the 6-month follow-up. Postoperative PV, International Prostate Symptom Score, quality of life, maximum flow rate, and post-void residual significantly improved after 6 months (P < 0.05). One month after PAE, the serum total PSA increased by 1.47 (10.84/7.37) times and dropped 3 months later to a level lower than that before surgery (P < 0.05). Six months after PAE, the degree of relief from obstructive symptoms was more apparent than that of irritative symptoms. No serious complications were observed after PAE. CONCLUSION PAE was safe and effective for the treatment of BPH. The efficacy of bilateral PAE was better than that of unilateral PAE.

Abstract
Objectives The aim was to describe the patients' experience of undergoing prostatic artery embolization. Methods A retrospective qualitative interview study was undertaken with 15 patients of mean age 73 years who had undergone prostatic artery embolization with a median duration of 210 min at two medium sized hospitals in Sweden. The reasons for conducting prostatic artery embolization were clean intermittent catheterization (n = 4), lower urinary tract symptoms (n = 10) or haematuria (n = 1). Data were collected through individual, semi-structured telephone interviews 1-12 months after treatment and analysed using qualitative content analysis. Results Four categories with sub-categories were formulated to describe the results: a diverse experience; ability to control the situation; resumption of everyday activities and range of opinions regarding efficacy of outcomes. Overall, the patients described the procedure as painless, easy and interesting and reported that while the procedure can be stressful, a calm atmosphere contributed to achieving a good experience. Limitations on access to reliable information before, during and after the procedure were highlighted as a major issue. Practical ideas for improving patient comfort during the procedure were suggested. Improved communications between treatment staff and patients were also highlighted. Most patients could resume everyday activities, some felt tired and bruising caused unnecessary worry for a few. Regarding functional outcome, some patients described substantial improvement in urine flow while others were satisfied with regaining undisturbed night sleep. Those with less effect were considering transurethral resection of the prostate as a future option. Self-enrolment to the treatment and long median operation time may have influenced the results. Conclusions From the patients' perspective, prostatic artery embolization is a well-tolerated method for treating benign prostate hyperplacia.

Abstract
PURPOSE To evaluate the use of prostatic artery embolization (PAE) as a treatment option for patients with symptomatic benign prostatic hyperplasia (BPH) with prostate volumes of 80 cc and more. MATERIALS AND METHODS The study included 75 patients with high anesthesia-related risks for conventional surgery (TURP). All patients were surveyed for symptom burden, using IPSS and quality of life score. The prostate volume was determined by transrectal ultrasonography (TRUS). At baseline, prostate-specific antigen (PSA) level was obtained in all patients. Urodynamics was evaluated using uroflowmetry. Clinical outcomes were assessed at follow-up 1, 3, 6, 12, and 24 months after PAE. RESULTS The prostate volume decreased significantly at months 1 and 3 post-treatment; the prostate continued shrinking until month 12, and the size was then stabilized. At month 24, prostate volume decreased by 40.82%, from 134.0 ± 8.3 mL at baseline to 79.3 ± 6.6 mL. Postvoid residual (PVR) urine volume was significantly decreased from 55.9 ± 5.3 mL to 22.0 ± 1.8 mL 1 month after PAE (p < 0.001). Qmax increased from 9.2 ± 0.3 mL/s to 15.7 ± 0.4 mL/s. IPSS score following PAE decreased from 28.2 ± 0.7 to 9.7 ± 0.8 (p < 0.001). QoL improvement was observed from 4.8 ± 0.2 at baseline to 1.8 ± 0.2 at month 24 (p < 0.001). Decreased activity and density of adenomatous tissue resulted in decreased total PSA levels: from 5.9 ± 1.1 ng/mL to 2.6 ± 0.2 ng/mL (p < 0.001). TURP became feasible in 35 patients due to reduction of prostate volumes below 80 mL after PAE. CONCLUSIONS PAE was effective in relieving LUTS and reducing prostate size, and may be considered as a preoperative approach for patients with large prostate.

A state-of-art review on the preservation of sexual function among various minimally invasive surgical treatments for benign prostatic hyperplasia: Impact on erectile and ejaculatory domains. Investig Clin Urol 2021; 62:148-158. [PMID: 33660441 PMCID: PMC7940857 DOI: 10.4111/icu.20200392] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 10/11/2020] [Accepted: 11/08/2020] [Indexed: 12/27/2022] Open
Abstract
There is a strong association between benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and sexual dysfunction. While transurethral resection of the prostate (TURP) is considered the standard BPH treatment, it is however associated with a high rate of erectile and ejaculatory dysfunctions. Over the past decade, new and novel minimally invasive BPH therapies have been shown to improve various parameters of voiding domains while minimizing adverse sexual effects. These minimally invasive BPH therapies can be largely be divided into those with cavitating technology (Rezum, Histotripsy, Aquablation), intra-prostatic injections (Botulinum neurotoxin Type A, Fexapotide Triflutate, prostate specific antigen-activated protoxin PRX-302), and mechanical devices which include intraprostatic stents (Urospinal 2™, Memotherm™, Memokath™, and Allium triangular prostatic stent™) and intraprostatic devices (iTIND™, Urolift™), as well as prostatic artery embolization. Published literature on these technologies showed reasonable preservation of erectile function with limited data reported on ejaculatory domain. Further validation of the performance of these novel minimally invasive treatment options for LUTS due to BPH in well-designed and multi-centre studies are desired, to evaluate their role (or lack of such a role) in clinical practice and whether these BPH therapies can provide equivalent standard or better than TURP.

Abstract
INTRODUCTION In the development of terminology of the lower urinary tract (LUT), due to its increasing complexity, the terminology for male LUT surgery needs to be updated using a male-specific approach and via a clinically-based consensus report. METHODS This report combines the input of members of the Standardization Committee of the International Continence Society in a Working Group with recognized experts in the field, assisted by many external referees. Appropriate core clinical categories and a subclassification were developed to give a numeric coding to each definition. An extensive process of 14 rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). RESULTS A Terminology Report for male LUT and pelvic floor surgery, encompassing 149 separate definitions/descriptors, has been developed. It is clinically-based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in male LUT surgery. Figures have not been included to avoid any preference or bias towards a specific procedure. CONCLUSIONS A consensus-based Terminology Report for male LUT surgery has been produced aimed at being a significant aid to clinical practice and a stimulus for research.

Abstract
Prostate artery embolization (PAE) is a minimally invasive treatment for benign prostatic hyperplasia associated lower urinary tract symptoms. The prostatic arterial anatomy, origins and collaterals, are highly variable and can lead to technical pitfalls and suboptimal results during PAE. In this paper we aim to discuss the variant prostate artery origins and collateral circulation to provide a primer on relevant anatomy for interventional radiologists performing PAE.

Abstract
Prostatic artery embolization (PAE) has been established as a routine treatment for symptomatic benign prostatic hyperplasia (BPH) all over the world. With increasing clinical experience in the last decade, investigators have sufficient data to assess predictive factors with the purpose to guide patient selection and counseling for PAE or to individualize therapeutic plans after PAE. This paper is a comprehensive review to introduce the concept of clinical predictors and give a systemic classification of various predictive factors in PAE. The authors review each individual factor and its predictive capability and discuss the possible reasons for the inconsistent or conflicting findings in the literature. Based on current evidence, the baseline prostate volume, in particular the transition zone volume and transition zone index; 24 h post-PAE prostate-specific antigen (PSA) level; and prostate infarction and prostate volume reduction at 1–3 months have potential in prediction of treatment outcomes. Patients with Adenomatous-dominant BPH or with indwelling bladder catheter before PAE may have more benefits from PAE. Baseline intravesical prostatic protrusion (IPP), C-reactive protein (CRP) level at 48 h and early detection of prostate infarct at 1 day and 1 week after PAE need further investigating.

Abstract
BACKGROUND In recent years prostate artery embolization (PAE) evolved into a clinically established minimally invasive endovascular treatment option for lower urinary tract symptoms caused by benign prostate syndrome (BPS). METHODS In this interdisciplinary position paper, initiated by the steering group for research of the German Society for Interventional Radiology (IR), the method of PAE is presented and discussed in the context of current evidence. RESULTS PAE is a safe IR procedure for the treatment of BPS. In terms of symptom relief, measured with the IPSS (International Prostate Symptom Score), the PAE has comparable effect, similar to the historic gold standard, transurethral resection (TUR) of the prostate. With regard to reducing subvesical obstruction PAE is inferior to TUR, but does not limit subsequent surgery. Based on current evidence, PAE is recommended by the British National Institute for Health and Care Excellence as an alternative therapy. The feasibility under local anaesthesia and the preservation of sexual function are important arguments for patients in favour of interventional therapy. Patient selection and therapy concepts require close interdisciplinary collaboration between urologists and radiologists. CONCLUSION Effectiveness and safety of PAE for the treatment of BPS are proven. Further randomized trials should focus on long term outcome and help to identify most suitable indications for PAE. KEY POINTS · PAE, an endovascular procedure, is a patient-friendly, minimally invasive, alternative therapy option of the BPS. · PAE can reduce the symptoms of the lower urinary tract (LUTS), comparable to transurethral resection (TUR). The deobstructive and volume-reducing potential of the PAE is inferior to that of the TUR. · The main advantages of PAE are use of local anesthesia (no general anesthesia required), short patient recovery and maintenance of sexual function, including antegrade ejaculation.. · Based on current evidence PAE should be considered after conservative drug therapy and before TUR.. · The role of PAE in the context of other minimally invasive procedures (MIST) requires further evaluation with an open minded approach towards PAE.. · PAE is carried out by interventional radiologists, usually on a referral basis from urologists, and requires close interdisciplinary cooperation..

Abstract
PURPOSE This study compared the safety and efficacy of prostatic arterial embolization (PAE) with that of trisacryl gelatin microspheres of different sizes for treatment of benign prostatic hyperplasia (BPH). MATERIALS AND METHODS This study consisted of a single-center, randomized controlled clinical trial in 138 patients who underwent PAE for BPH between July 2015 and December 2016. Patients were randomized to PAE using microspheres of different sizes: group A patients were treated with microspheres 100-300 μm, group B with 300-500 μm, and group C with 100-300 μm followed by 300-500 μm. All patients were evaluated before and at 1, 3, 6, 12, and 18 months after PAE. Baseline data were comparable across the 3 groups, using the following mean International Prostate Symptom Score/quality of life (IPSS/QoL); prostate volume (PV) scores, respectively: 23.0/4.14; 87.9 cm3 (group A); 23.0/4.09; 89.0 cm3 (group B); and 24.2/4.29; 81.0 cm3 (group C) (P > 0.05). RESULTS Mean IPSS/QoL scores; PV after PAE were: 9.98/2.49; 65.1 cm3 (group A); 8.24/2.26; 63.1 cm3 (group B); and 10.1/2.69; 53.1 cm3 (group C) (P = 0.23; P = 0.39; P = 0.24). There were 26 clinical failures. The cumulative probabilities of clinical success at 18 months were 76.7% in group A, 82.6% in group B, and 83.3% in group C (P = 0.68). Nontarget embolization was prevented in 6 patients by coil embolization. All adverse events were mild and self-limited with rates of 86.0% in group A (37 of 43); 41.3% in group B (19 of 46); and 58.3% in group C (28 of 48) (P < 0.001). Dysuria was the most frequent adverse event (28 of 137 [20.4%]). CONCLUSIONS PAE outcomes were not significantly different among microspheres of different sizes. The use of 100- to 300-μm microspheres was associated with an increased risk of minor adverse events.

Abstract
OBJECTIVE To investigate whether prostatic arterial embolization (PAE) could be recommended as a routine therapy for benign prostatic hyperplasia (BPH), we conducted an updated meta-analysis to assess the efficacy and safety of PAE compared with transurethral resection of the prostate (TURP). METHODS Systematic literature retrieval by searching data from Web of science, Pubmed, Embase, Cochrane Library, ClinicalTrial.gov, CNKI, Wanfang and VIP databases was carried out to identify all related trials from the inception dates to June 2019. We also conducted subgroup analyses depending on the kind of study design, kind of PAE and kind of TURP. RESULTS Nine studies comparing PAE with TURP involving a total of 860 BPH patients were selected. Postoperative reduced IPSS score (MD 2.50; 95% CI 0.78-4.21; P = 0.004), postoperative reduced QOL score (MD 0.40; 95% CI 0.09-0.71; P = 0.01), postoperative reduced PV (MD 8.59; 95% CI 4.74-12.44; P < 0.00001) and postoperative increased Qmax (MD 2.54; 95% CI 1.02-4.05; P = 0.001) were better in TURP than in PAE; however, PAE was associated with lower sexual dysfunction rate (OR 0.24; 95% CI 0.15-0.39; P < 0.00001) compared with TURP. Meanwhile, no significant difference in postoperative reduced PVR (MD 0.46; 95% CI - 2.08 to 3.00; P = 0.72) and complication (OR 0.57; 95% CI 0.21-1.55; P = 0.27) between PAE and TURP group was demonstrated. CONCLUSION PAE was inferior to TURP in the improvement of postoperative IPSS, QOL, PV, Qmax and TURP still remained the gold standard. However, PAE may be a valuable alternative to TURP in the treatment of BPH patients who refuse surgery or with surgery contraindication.

Abstract
OBJECTIVE To present the results of a multidisciplinary study of two tertiary hospitals, together with urology services, on 102 consecutive patients not candidates for surgery treated for more than 6 years, in whom prostatic arteries were embolised for the treatment of benign hyperplasia. MATERIAL AND METHODS From December 2012 to February 2019, 102 patients with symptoms of benign prostatic hyperplasia (BPH) not candidates for surgery or who explicitly rejected surgery, with an average age of 73.9 years (range 47.5-94.5), underwent prostatic artery embolisation. The patients were followed up by questionnaires on urinary symptoms, sexual function and impact on quality of life, as well as measurement of prostate volume, uroflowmetry and prostate specific antigen (PSA) at one, 3 and 6 months and one year following the procedure. RESULTS The technique was successful in 96% of patients (76.2% bilateral and 19.8% unilateral). The mean duration of the procedure was 92minutes and of the radioscopy 35.2minutes. Statistically significant changes were demonstrated (p <.05) in PSA, peak urinary flow, QoL (quality of life) questionnaire and the International Index of Erectile Function (IPSS). PSA had reduced by 58% from baseline at 3 months. Similarly, the Qmax had increased significantly by 63% in the third month following embolisation. A significant improvement in the QoL and IPSS tests was achieved, with a reduction of 3.7 points and a mean 13.5 points, respectively, at one year's follow-up. Prostate volume showed a non-statistically significant decrease at follow-up of one year following treatment. A series of minor complications was collected, no case of which required hospital admission. CONCLUSIONS Prostatic embolisation for the treatment of BPH proved an effective and safe technique in patients who were not candidates for surgery.

Abstract
Background Benign prostate hyperplasia (BPH) remains a common cause of lower urinary tract symptoms (LUTS) in ageing men in South Africa and can impact significantly on the quality of life (QOL) of these patients. The Urology Department at Steve Biko Academic Hospital (SBAH) can generally only offer men with LUTS the following treatment options: watchful waiting, medical treatment and surgical management. In men with symptomatic BPH, who are refractory to medical treatment, where anaesthesia is contra-indicated because of co-morbidities or transurethral resection of the prostate (TURP) is contra-indicated because of the prostate size, the Urology and Radiology departments at SBAH recently introduced prostate artery embolisation (PAE). Aim To assess the outcome of PAE in 10 men with LUTS, secondary to BPH, by comparing their urinary symptoms, QOL and prostate volume before and 3 months after they underwent PAE in the Radiology Department at SBAH. Method The review included the first 10 men who had undergone therapeutic PAE for symptomatic BPH from May 2016 to September 2016. The subjective symptomatic feedback was assessed according to the International Prostate Symptom Score (IPSS) and the Global Quality of Life questionnaire, created by the American Urological Association (AUA). The reduction in the size of the prostate was measured on magnetic resonance imaging (MRI). Results Embolisation was technically achieved in all 10 patients. Bilateral embolisation was performed on nine patients. One patient received unilateral embolisation secondary to unilateral tortuous and atherosclerotic changes of the iliac arteries. Within the 3-month follow-up, the mean IPSS score improved by 15.7 points (p < 0.0039), the mean QOL improved by 4.1 points (p < 0.0039) and the mean prostate volume reduction was 21.8 mL (p < 0.0039). Despite improvements observed, there was one clinical failure. No major complications were reported that increased hospital stay, required hospital readmission or required surgery. Conclusion The study on the first 10 PAE performed in SBAH concludes that PAE is a safe and effective procedure with favourable short-term follow-up results. This indicates that PAE can safely be offered to patients, who are refractory to medical treatment and not suitable candidates for surgery, in urology departments such as in SBAH.

Abstract
Background A major technical challenge of prostatic arterial embolization (PAE) is the identification and catheterization of the prostatic arteries (PAs). Recently, MR angiography has been shown to help visualize PAs, but the clinical utility of MR angiography for this purpose is not known. Purpose To determine the efficacy of contrast material-enhanced MR angiography in identifying the PA and to evaluate its role in PAE for benign prostatic hyperplasia (BPH). Materials and Methods In this prospective study, 100 consecutive men who were scheduled to undergo PAE for BPH from January 2015 to May 2017 were assigned by using a randomized block design to either group A (n = 50; mean age, 71.7 years ± 11.9 [standard deviation]) without MR angiography or group B (n = 50; mean age, 72.3 years ± 12.2) with MR angiography prior to PAE. MR angiography findings of the PA anatomy were compared with those of digital subtraction angiography (DSA). The Student t test and Wilcoxon rank-sum test were used to compare the differences between the parameters indicating the performance of PAE. Results The mean age of the 100 men in the study was 72.0 years ± 11.8 (range, 51-88 years). Compared with DSA as the reference standard, MR angiography identified PAs with a sensitivity of 91.5% (97 of 106) and a positive predictive value of 100% (97 of 97). With the knowledge of tube obliquity and anatomy, group B had lower procedure times than group A (82.3 minutes ± 5.4 vs 123.9 minutes ± 12.4, P < .001) and shorter fluoroscopy times (13.8 minutes ± 2.7 vs 28.5 minutes ± 8.0, P < .001). Additionally, radiation dose was reduced for group A versus group B, from a median of 920 to 339 mGy (P = .004). Conclusion Contrast-enhanced MR angiography can accurately show anatomy for the prostate arteries, leading to shorter prostatic artery embolization times and lower radiation dose than when preprocedural prostate MR angiography is not performed.

Abstract
Purpose The study aims to report our very early experience with prostate artery embolisation in patients with benign prostatic hypertrophy (BPH) in an Indian setting. Material and methods This prospective study was approved by the Institutional Ethical Review Board, and informed consent was obtained from all the patients. Four patients with lower urinary tract symptoms due to benign prostatic hyperplasia underwent prostate embolisation. Embolisation was performed using polyvinyl alcohol (PVA) particles. International Prostate Symptom Score (IPSS), quality of life (QOL) score, postvoid residual volume, and prostate volume was recorded in each patient for 12 months. No major complications were seen in any patient. Results Four patients with a mean age of 74.2 years underwent prostate artery embolisation. It was successful in all the cases. Bilateral embolisation was performed in three patients and unilateral approach in one patient. Clinical improvement was characterised by a mean prostate volume reduction of 22% and mean IPSS reduction of 30% at 12-month follow-up. Conclusions The initial experience with prostate embolisation has been very rewarding and is a great alternative treatment for BPH. It is a very safe and effective procedure and can be an ideal procedure from an Indian perspective.

Abstract
Background Prostate artery embolization is an emerging technique, that with the continued publication of promising data, is slowly moving from the research to the everyday clinical setting. Main body This paper reviews the patient selection, clinical management and expected results of prostate artery embolization. Patient selection is paramount in delivering the desired results for any procedure. Likewise, the ability to clinically manage patients in the pre-operative and post-operative setting is an important skill to acquire when implementing new techniques. This paper introduces important urologic measurements/tests, patient selection paradigms, and clinical management concepts for interventional radiologists. It also reviews the outcomes patients can expect following prostate artery embolization as well as the complication profile. Conclusion Prostate artery embolization is a promising technique for the treatment of benign prostatic hyperplasia induced lower urinary tract symptoms.

Abstract
PURPOSE Prostatic artery embolization (PAE) has seen a recent increase in interest as a treatment for men with benign prostatic obstruction (BPO). The appeal of this intervention lies in reported reduction in morbidity and its minimally invasive nature. The purpose of this review is to assess the safety and efficacy of PAE as a new treatment in BPO and explore risks surrounding its performance. METHODS A review of the literature was performed. Medical databases searched included PubMed, EMBASE, and Cochrane databases, limited to English, peer-reviewed articles. Search terms included prostatic artery embolization, lower urinary tracts symptoms, minimally invasive therapies, interventional radiology prostate, and benign prostatic hyperplasia. Articles were screened by two independent reviewers for content on development, methods, outcomes, and complications of PAE. RESULTS Suitability of patients to undergo PAE depends on review of patient history, pre-procedure visualisation of appropriate vascular anatomy and clinical parameters. Despite this selection of candidates favourable for procedural success, PAE is not without risk of complications, some of which can significantly affect patient quality of life. CONCLUSIONS Although initial findings show promise regarding safety and efficacy of PAE in improving symptom and quality-of-life scores, further investigation is required to establish durability of effect and the appropriate use of this experimental modality. There is currently limited robust evidence for the beneficial outcomes of PAE. Long-term follow-up studies will add to the evidence base to help further assess the feasibility of this procedure as an alternative to TURP.

Abstract
Introduction Non-surgical minimally invasive treatments are greatly needed for patients with symptomatic benign prostatic hyperplasia (BPH), for whom medical treatment has failed and surgery is contraindicated. This study retrospectively evaluated the efficacy and safety of super-selective prostatic artery embolization (PAE) for BPH, relative to transurethral resection of the prostate (TURP). Aim To clinically evaluate the efficacy and safety of super-selective PAE for BPH, relative to TURP. Material and methods From February 2012 to March 2015, patients with BPH underwent selective PAE (n = 17) or TURP (control group; n = 40). Prostate volume, maximum urinary flow rate (Qmax), International Prostate Symptoms Score (IPSS), and quality of life (QoL) score were evaluated at baseline and postoperative 3, 6, and 12 months. Complications were also recorded. Results All the procedures were technically successfully. At postoperative 1 year, patients given PAE had significantly greater prostate volume (64.6 ±10.2 ml), IPSS (23.9 ±4.9), and QoL (4.1 ±0.7) compared with the control patients (42.0 ±7.5 ml, 13.1 ±3.5, and 2.1 ±0.7, respectively). The Qmax of the PAE group (9.5 ±3.7 ml/s) was significantly lower than that of the control (21.8 ±4.2 ml/s). The changes in parameters of the TURP patients relative to the preoperative baseline were significantly greater than those of the PAE group. No severe complications occurred. Conclusions Prostatic artery embolization was demonstrated as safe and effective and may be considered an alternative treatment for BPH patients, especially for those who are not candidates for or refuse surgery.

Abstract
Purpose To report early results following prostatic artery embolization (PAE) and compare outcomes between nonspherical polyvinyl alcohol (PVA) particles and microspheres to treat lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). Methods PAE was performed in nine patients (mean age: 78.1 years) with symptomatic BPH. Embolization was performed using nonspherical PVA particles (250–355 μm) in four patients and microspheres (300–500 μm) in five patients. Results PAE was technically successful in all nine patients (100%). During a mean follow-up of 10.1 months, improvements in mean International Prostate Symptom Score (IPSS), Quality of Life (QoL), prostatic volume (total volume and transition zone), and peak urinary flow (Qmax) were 9.8 points, 2.3 points, 28.1 mL, 17.8 mL, and 4.5 mL/s, respectively. Clinical success was obtained in seven of nine patients (78%). Patients in the microsphere group showed greater improvement in IPSS, QoL, prostatic volume, and Qmax compared to patients in the nonspherical PVA particle group. However, significant difference was noted only in the prostatic volume. Conclusion PAE is a feasible, effective, and safe treatment option for BPH with LUTS. Use of microspheres showed greater prostatic volume reduction compared to nonspherical PVA particles.

Abstract
PURPOSE To explore the morphological and functional characteristics of prostatic arterial embolization (PAE) in a canine model of benign prostatic hyperplasia (BPH) with 3T multiparametric magnetic resonance imaging (mp-MRI) and whole-mount step-section pathology correlation. MATERIALS AND METHODS Eight adult male beagle dogs with hormone-induced BPH underwent 3T mp-MRI before and 1, 3, and 6 months after PAE, with subsequent whole-mount step-section pathologic assessment. Images were acquired using T1 -weighted images (T1 WI), T2 WI, 3D-SPACE, diffusion-weighted imaging (DWI), susceptibility-weighted imaging (SWI), T2 -mapping, and dynamic contrast-enhanced (DCE) sequences. Variance analysis was performed to assess statistical differences in prostatic volume (PV), apparent diffusion coefficient (ADC), and T2 values. Pearson correlation analysis was performed to correlate ADC, T2 , and PV. RESULTS The PV decreased from baseline to 1, 3, and 6 months after PAE from (25.88 ± 7.09) cm3 to (6.48 ± 2.08) cm3 , (6.48 ± 3.39) cm3 , (6.20 ± 2.88) cm3 . The ADC values sequentially decreased from baseline to 1, 3, and 6 months after PAE from (1497.06 ± 222.72) × 10-6 mm2 /s to (1056.00 ± 189.46) × 10-6 mm2 /s, (950.48 ± 77.85) × 10-6 mm2 /s, (980.98 ± 107.78) × 10-6 mm2 /s. The T2 values decreased from baseline to 1, 3, and 6 months after PAE were (83.74 ± 5.29) msec, (68.72 ± 5.66) msec, (53.96 ± 15.04) msec, (49.81 ± 13.34) msec, respectively. ADC and T2 values were positively correlated with PV (r = 0.823 and 0.744, respectively). Microhemorrhages and hemosiderin were found on SWI after PAE. CONCLUSION 3T mp-MRI may facilitate noninvasive assessment of morphological and functional changes of BPH after PAE. LEVEL OF EVIDENCE 1 Technical Efficacy: Stage 2 J. Magn. Reson.
