Abstract
AIM OF THE STUDY Among minimally invasive procedures for treating benign prostate hyperplasia (BPH) prostate artery embolisation (PAE) is described as safe and effective. Aim of this study is to report our results, focusing on sexual outcomes (erectile and ejaculatory functions sparing) of PAE in patients suffering from bladder outlet obstruction (BOO) secondary to BPH. METHODS We prospectively enrolled and submitted to PAE subjects suffering from BOO secondary to BPH. All patients were not suitable for surgery or declined invasive approaches. All subjects were preoperatively and postoperatively (3, 6, 12 and 18 months after) evaluated by urinary flowmetry, post voiding residual volume, prostate volume, serum PSA levels, International Index of Erectile Function, International Prostate Symptom Score and QoL scores. RESULTS PAE was performed in 147 patients (mean age 72.5 y.o.). PAE was technically successful in all patients. The procedure lasted a mean time of 94.3 minutes, with a mean fluoroscopic time of 42.5 minutes. Twelve months follow-up data were available for all patients, while 126 patients (85%) completed the 18 months follow up. At 12 months follow up, the mean IPSS and QoL scores significantly decreased, and all the objective parameters (mean Qmax, PVR and prostate volume) reported a significant improvement. A total of 130 patients (88.5%) at 12 months reported the antegrade ejaculation preserved, and a slight not significant improvement of IIEF scores. The 18 months after PAE outcomes confirmed the significant improvement of all the variables evaluated (even for PSA values and IIEF scores). No major complications occurred. CONCLUSIONS Our results evidence prostate artery embolisation as highly feasible and safe procedure with interesting outcomes. In particular, in our study PAE reported promising results in preserving antegrade ejaculation and erectile function. Our data are in line with the literature, confirming how PAE reduces obstructive symptoms in BPH patients not suitable or refusing standard surgical approaches.

Abstract
PURPOSE To study the subscore improvement in International Prostate Symptom Scores (IPSS) after prostatic artery embolization (PAE). MATERIALS AND METHODS A single-center retrospective study was carried out with follow-up from December 2013 to July 2019 in 37 consecutive patients (66.0 ± 8.8 years old) who underwent PAE, comparing resultant scores before and after PAE. IPSS were divided into storage (IPSS-s) subscores and voiding (IPSS-v) subscores. The changes between IPSS-s and IPSS-v at 1, 3, 6, and 12 months' follow-up as well as the last follow-up were compared with baseline scores. The changes in percentages of IPSS-s and IPSS-v and the changes in average IPSS-s-to-total IPSS ratios (IPSS-s/IPSS-t) and IPSS-v-to-IPSS-t ratios (IPSS-v/IPSS-t) were also analyzed. RESULTS In the study population, consisting of 37 patients, IPSS-t significantly decreased from 16.5 ± 7.2 at baseline to 8.3 ± 5.7 at the last follow-up (4 years later) (P < .0001). Additionally, the changes in IPSS-v symptoms were greater than the changes in IPSS-s symptoms at 1, 3, 6, and 12 months' follow-up, reaching a statistical significance at 6 months with a decrease of 72.9% ± 42.4% for IPSS-v and a decrease of 50.1% ± 52.2% for IPSS-s (P = .009). CONCLUSIONS PAE can successfully reduce both IPSS-s and IPSS-v with predominant IPSS-v reduction. The improvements in both subscores were sustained for up to 4 years of follow-up.

Abstract
In recent years new surgical techniques to treat benign prostatic hyperplasia have been introduced into urological practice and evaluated in clinical studies. Complications of standard procedures, e.g. transurethral resection of the prostate (TURP), can be avoided while maintaining equivalent clinical outcomes. The main goal is preservation of erectile and ejaculatory function. Furthermore, outpatient treatment associated with a rapid patient recovery would be desirable. This article presents the course of the interventions, the mechanisms of action and current clinical evidence for novel mechanical approaches of recanalization, water-based ablation as well as prostate artery embolization. Initial study results partially indicate that in the future practically all patients can be offered an individualized surgical technique, which provides optimal symptomatic and functional improvements with a minimized risk of complications.

Abstract
In recent years multidetector computed tomography (MDCT) has been used to investigate vascular anatomy for scientific and diagnostic purposes. These studies allow for much larger sample sizes than traditional cadaveric studies. The aim of this research was to perform a systematic review and meta-analysis on studies investigating the variations of the celiac trunk using MDCT. Major medical databases were used to find studies investigating celiac trunk anatomy using MDCT. Extracted information included demographic details, number of normal celiac trunks, and number of each variant celiac trunk. Using a random effects meta-analysis the pooled prevalence of each variation was calculated. A total of 36 studies from 14 countries and four continents were included in the meta-analysis. The total number of subjects included was 17,391. The total prevalence of variant celiac trunks was 10.85%. The different types of celiac trunk variations with their prevalences were: gastrosplenic trunk (3.46%), hepatosplenic trunk (3.88%), hepatogastric trunk (0.24%), absent celiac trunk (0.28%), celiacomesenteric trunk (0.46%), hepatosplenomesenteric trunk (0.26%), gastrosplenomesenteric trunk (0.07%), and celiacomesenteric anastomosis (0.09%). A total of 61 cases (0.19%) were either not described or not described adequately to be included in our classification. Major variations of the celiac trunk are not uncommon and should be anticipated before radiological and surgical interventions. Knowledge of celiac trunk anatomy is important in hepatopancreatobiliary surgery, transplantology, and interventional radiology.

Abstract
Prostatic artery embolisation (PAE) is used to treat patients with benign prostatic hyperplasia and with lower urinary obstructive tract symptoms. It is an interventional procedure which uses fluoroscopy equipment and can result in exposure to high doses of radiation in patients and staff. We aimed to demonstrate the reduction of radiation doses received by staff during PAE by implementing an optimised protocol called Radiation Exposure Curtailment for Embolisation (RECiFE). This protocol was implemented in cooperation with the medical team and technical team using Siemens Combined Applications to Reduce Exposure (CARE) protocol. The results showed approximately 83% reduction in the radiation doses received by the main physician during PAE. Thus, by adjusting the acquisition parameters of the angiographic equipment and implementing the RECiFE protocol, it is possible to optimise the PAE procedure and reduce the staff radiation dose.

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
BACKGROUND In previous studies, celiomesenteric trunk (CMT) was narrowly defined as a hepato-gastro-spleno-mesenteric (HGSM) trunk, but other possible types were ignored. With the widespread use of multidetector computed tomography (MDCT) angiography, it is easy to collect a large sampling of data on arterial anatomy of the abdomen in daily radiological practice. A new classification system for CMT may be created based on its MDCT angiographic findings and variation patterns.
AIM To identify the spectrum and prevalence of CMT according to a new classification based on MDCT angiographic findings, and discuss the probable embryological mechanisms to explain the CMT variants.
METHODS A retrospective study was carried out on 5580 abdominal MDCT angiography images. CMT was defined as a single common trunk arising from the aorta and its branches including the superior mesenteric artery and at least two major branches of the celiac trunk. Various types of CMT were investigated.
RESULTS Of the 5580 patients, 171 (3.06%) were identified as having CMT. According to the new definitions and classification, the CMT variants included five types: I, II, III, IV and V, which were found in 96 (56.14%), 57 (33.33%), 4 (2.34%), 3 (1.75%) and 8 (4.68%) patients, respectively. The CMT variants also were classified as long type (106 patients, 61.99%) and short type (65 patients, 38.01%) based on the length of single common trunk. Further CMT classification was based on the origin of the left gastric artery: Type a (92 patients, 53.80%), type b (57 patients, 33.33%), type c (11 patients, 6.43%) and type d (8 patients, 4.68%).
CONCLUSION We systematically classified CMT variants according to our new classification system based on MDCT angiographic findings. Dislocation interruption, incomplete interruption and persistence of the longitudinal anastomosis could all be embryological mechanisms of various types of CMT variants.

Abstract
PURPOSE To summarize the Society of Interventional Radiology Foundation's Research Consensus Panel development of a research agenda on prostate artery embolization (PAE). MATERIALS AND METHODS PAE for the treatment of lower urinary tract symptoms has been shown to be safe and effective in decreasing symptoms and prostate size. Lack of randomized controlled trials (RCTs) on PAE in the United States has prevented inclusion in American Urologic Association guideline recommendations for treatment of lower urinary tract symptoms resulting from benign prostatic hyperplasia. Recognizing the need for well-designed trials, the SIR Foundation funded a Research Consensus Panel to prioritize a research agenda. The panel included interventional radiologists, urologists, SIR Foundation leadership, and industry representatives. The goal of the meeting was to discuss weaknesses with current data and study design for development of US trials to report long-term outcomes data. RESULTS Final consensus on a research design could not be made because the group was split on 3 research designs: (i) RCT of PAE versus sham with crossover of the sham group. (ii) RCT of PAE versus simple prostatectomy. (iii) RCT of PAE versus holmium laser enucleation of the prostate/thulium laser enucleation of the prostate. The panel recommended a nonindustry-funded registry to obtain real-world data. CONCLUSIONS Level 1 data are required to be included in the American Urologic Association guidelines for treatment of benign prostatic hyperplasia. Because of concerns with all 3 study designs, the panel did not reach a consensus. Further meetings are planned with the panel to select among these research designs.

RADIOLOGIA 2019; 62:205-212. [PMID: 31757401 DOI: 10.1016/j.rx.2019.07.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Revised: 07/23/2019] [Accepted: 07/29/2019] [Indexed: 11/16/2022]
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
PURPOSE To determine if cone-beam CT and digital subtraction angiography analysis of pelvic arterial anatomy has predictive value for radiation exposure and technical success of prostatic artery embolization (PAE). MATERIALS AND METHODS This prospective, nonrandomized, single-center study included 104 consecutive patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia. Cone-beam CT was performed in 160/208 (76.9%) hemipelves to determine prostatic artery (PA) origin. Classification of pelvic arterial tortuosity was possible in 73/104 (70.2%) patients. Learning curves of 2 interventionalists who performed 86.5% of PAEs were analyzed. RESULTS Tortuosity of pelvic arteries was classified as mild in 25 (34.2%) patients median age 64 years, moderate in 40 (54.8%) patients median age 69 years, and severe in 8 (11.0%) patients median age 70 years (mild vs moderate, P = .002; mild vs severe, P = .019); median fluoroscopy times were 24, 36, and 46 minutes (P = .008, P = .023); median contrast volumes were 105, 122.5, and 142 mL (P = .029, P = .064); and bilateral PAE rates were 84.0%, 77.5%, and 62.5% (P = .437), respectively. PA origin from superior vesical artery was most frequent (27.5%) and showed higher dose area product (median 402.4 vs 218 Gy ∙ cm2, P = .033) and fluoroscopy time (median 42.5 vs 27 min, P = .01) compared with PA origin from obturator artery, which was least frequent. Interventionalist experience revealed significant impact on procedure times (median 159 vs 130 min, P = .006). CONCLUSIONS Tortuosity of pelvic arteries was more frequent in older patients and predicted worse technical outcomes of PAE. PA origin from obturator artery was associated with lower dose area product and fluoroscopy time, especially compared with PA origin from superior vesical artery. Interventionalist experience showed significant influence on technical outcome.

BJR Open 2019; 1:20190019. [PMID: 33178947 PMCID: PMC7592499 DOI: 10.1259/bjro.20190019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Revised: 07/04/2019] [Accepted: 08/01/2019] [Indexed: 12/13/2022] Open
Abstract
Multiparametric MRI (mpMRI) has proven to be an essential tool for diagnosis, post-treatment follow-up, aggressiveness assessment, and active surveillance of prostate cancer. Currently, this imaging technique is part of the daily practice in many oncological centres. This manuscript aims to review the use of mpMRI in the set of prostatic diseases, either malignant or benign: mpMRI to detect and stage prostate cancer is discussed, as well as its use for active surveillance. Image-guided ablation techniques for prostate cancer are also reviewed. The need to establish minimum acceptable technical parameters for prostate mpMRI, standardize reports, uniform terminology for describing imaging findings, and develop assessment categories that differentiate levels of suspicion for clinically significant prostate cancer led to the development of the Prostate Imaging Reporting and Data System that is reviewed. Special focus will also be given on the most up-to-date evidence of prostatic artery embolization (PAE) for symptomatic benign prostatic hyperplasia (BPH). Management of patients with BPH, technical aspects of PAE, expected outcomes and level of evidence are reviewed with the most recent literature. PAE is a challenging technique that requires dedicated anatomical knowledge and comprehensive embolization skills. PAE has been shown to be an effective minimally-invasive treatment option for symptomatic BPH patients, that can be viewed between medical therapy and surgery. PAE may be a good option for symptomatic BPH patients that do not want to be operated and can obviate the need for prostatic surgery in up to 80% of treated patients.

Accurate identification of myocardial viability after myocardial infarction with novel manganese chelate-based MR imaging. NMR IN BIOMEDICINE 2019; 32:e4158. [PMID: 31393647 DOI: 10.1002/nbm.4158] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 06/17/2019] [Accepted: 07/02/2019] [Indexed: 02/05/2023]
Abstract
We developed a novel manganese (Mn2+ ) chelate for magnetic resonance imaging (MRI) assessment of myocardial viability in acute and chronic myocardial infarct (MI) models, and compared it with Gadolinium-based delay enhancement MRI (Gd3+ -DEMRI) and histology. MI was induced in 14 rabbits by permanent occlusion of the left circumflex coronary artery. Gd3+ -DEMRI and Mn2+ chelate-based delayed enhancement MRI (Mn2+ chelate-DEMRI) were performed at 7 days (acute MI, n = 8) or 8 weeks (chronic MI, n = 6) after surgery with sequential injection of 0.15 mmol/kg Gd3+ and Mn2+ chelate. The biodistribution of Mn2+ in tissues and blood was measured at 1.5 and 24 h. Blood pressure, heart rate (HR), left ventricular (LV) function, and infarct fraction (IF) were analyzed, and IF was compared with the histology. The Mn2+ chelate group maintained a stable hemodynamic status during experiment. For acute and chronic MI, all rabbits survived without significant differences in HR or LV function before and after injection of Mn2+ chelate or Gd3+ (p > 0.05). Mn2+ chelate mainly accumulated in the kidney, liver, spleen, and heart at 1.5 h, with low tissue uptake and urine residue at 24 h after injection. In the acute MI group, there was no significant difference in IF between Mn2+ chelate-DEMRI and histology (22.92 ± 2.21% vs. 21.79 ± 2.25%, respectively, p = 0.87), while Gd3+ -DEMRI overestimated IF, as compared with histology (24.54 ± 1.73%, p = 0.04). In the chronic MI group, there was no significant difference in IF between the Mn2+ chelate-DEMRI, Gd3+ -DEMRI, and histology (29.50 ± 11.39%, 29.95 ± 9.40%, and 29.00 ± 10.44%, respectively, p > 0.05), and all three were well correlated (r = 0.92-0.96, p < 0.01). We conclude that the use of Mn2+ chelate-DEMRI is reliable for MI visualization and identifies acute MI more accurately than Gd3+ -DEMRI.

Abstract
PURPOSE To evaluate the radiation dose in patients undergoing prostatic artery embolization (PAE) using cone-beam CT and 3-dimensional (3D) guidance software. MATERIALS AND METHODS In this single-center retrospective study, 100 patients with benign prostatic hyperplasia (mean prostate volume, 83.6 mL ± 44.2; 69.4 ± 9.6 years of age; body mass index, 26.5 ± 4.2) were treated using PAE between October 2016 and April 2018. Informed consent was obtained from all participants included in the study. All patients received at least 1 intraprocedural cone-beam CT per side for evaluation of the vessel anatomy and software rendering of 3D guidance for catheter guidance. Digital subtraction angiography (DSA) was performed in the distal branches only. The total dose area product (DAP), along with the DAP attributed to fluoroscopy, DSA, and cone-beam CT, were assessed. RESULTS Bilateral embolization was achieved in 83 patients (83%). The average total DAP was 134.4 Gy ⋅ cm2 ± 69.5 (range, 44.7-410.9 Gy ⋅ cm2). Fluoroscopy, DSA, and cone-beam CT accounted for 35.5 Gy ⋅ cm2 ± 21.3 (range, 8.6-148.6 Gy ⋅ cm2) or 26.4% (percentage of total DAP), 58.2 Gy ⋅ cm2 ± 48.3 (range, 10.3-309.3 Gy ⋅ cm2) or 43.3%, and 40.7 Gy ⋅ cm2 ± 14.5 (range, 15.9-86.3 Gy ⋅ cm2) or 30.3%, respectively. Average procedure time was 89.4 ± 27.0 minutes, and the average fluoroscopy time was 30.9 ± 12.2 minutes. CONCLUSIONS Intraprocedural cone-beam CT in combination with 3D guidance software allows for identification and catheterization of the prostatic artery in PAE. Furthermore, the results of this trial indicate that this study protocol may lead to a low overall radiation dose.

Abstract
Symptomatic benign prostatic hyperplasia is a common condition in the aging population that results in bothersome lower urinary tract symptoms and decreased quality of life. Patients often are treated with medication and offered surgery for persistent symptoms. Transurethral resection of the prostate is considered the traditional standard of care, but several minimally invasive surgical treatments also are offered. Prostatic artery embolization (PAE) is emerging as an effective treatment option with few reported adverse effects, minimal blood loss, and infrequent overnight hospitalization. The procedure is offered to patients with moderate to severe lower urinary tract symptoms and depressed urinary flow due to bladder outlet obstruction. Proper patient selection and meticulous embolization are critical to optimize results. To perform PAE safely and avoid nontarget embolization, interventional radiologists must have a detailed understanding of the pelvic arterial anatomy. Although the prostatic arteries often arise from the internal pudendal arteries, several anatomic variants and pelvic anastomoses are encountered. Prospective cohort studies, small randomized controlled trials, and meta-analyses have shown improved symptoms after treatment, with serious adverse effects occurring rarely. This article reviews the basic principles of PAE that must be understood to develop a thriving PAE practice. These principles include patient evaluation, review of surgical therapies, details of pelvic arterial anatomy, basic principles of embolization, and an overview of published results. Online supplemental material is available for this article. ©RSNA, 2019.

Abstract
OBJECTIVES The aim of this study was to evaluate the feasibility of a computed tomography (CT) protocol enabling the visualization of the prostatic artery (PA) before prostatic artery embolization (PAE) in benign prostatic hyperplasia, which provides quantitative perfusion information of the prostate gland. MATERIALS AND METHODS In this institutional review board-approved study, 22 consecutive patients (mean age, 67 ± 7 years) who were planned to undergo PAE underwent a dynamic CT scan of the pelvis (scan range, 22.4 cm; cycle time, 1.5 seconds; scan time, 44 seconds; 25 scan cycles; 70 kVp; 100 mAs) after the administration of 70 mL of iodinated contrast media (flow rate, 6 mL/s; 10 seconds' delay). Image postprocessing consisted of a spatiotemporal, frequency-depending multiband filtering technique with noise reduction, motion correction, resulting in (1) time-resolved, temporal maximum intensity projection (MIP) images from fusion of multiple arterial time points; (2) 4-dimensional (4D) CT angiography images after bone and calcium plaque removal; and (3) parametric perfusion maps of the prostate. Intraprocedural cone-beam CT was performed with a microcatheter in the PA. In both modalities, the contrast-to-noise ratio of the right internal iliac artery or the PA was calculated, respectively. Visibility of the PA was scored using a Likert scale (score 1 = not seen, to score 4 = intraprostatic PA branches seen). Quantitative perfusion analysis of the dynamic pelvic CT included calculation of the blood flow, blood volume, mean transit time, and flow extraction product. RESULTS The average volume CT dose index and dose length product of CT was 35.7 ± 6.8 mGy and 737.4 ± 146.3 mGy·cm, respectively. Contrast-to-noise ratio of the pelvic vessels on temporal MIP images and cone-beam CT were 45 ± 19 and 69 ± 27, respectively (P < 0.01). The mean visibility score of the PA was 3.6 ± 0.6 for 4D-CT angiography and 3.97 ± 0.2 for cone-beam CT (P < 0.001). The PA was visualized in 100% of 4D-CT angiography examinations, with one PA being visible only proximally. Prostate CT perfusion analysis showed blood flow, blood volume, mean transit time, and flow extraction product values of 27.9 ± 12.5 mL/100 mL/min, 2.0 ± 0.8 mL/100 mL, 4.5 ± 0.5 second, and 12.6 ± 5.4 mL/100 mL/min, respectively, for the whole prostate gland. About half the patients showed a pronounced difference between the lobes. CONCLUSIONS We introduced a CT protocol for PAE planning providing excellent visualization of the PA on temporal MIP images and 4D-CT angiography at a reasonable dose and low contrast volume. In addition, quantitative perfusion information is available, which might be useful for outcome prediction after embolization.

Abstract
Background: Transurethral resection of the prostate (TURP) is 'Gold Standard' treatment for moderate-to-severe lower urinary tract symptoms (LUTS) due to benign prostate hyperplasia (BPH) with bladder-outlet obstruction (BOO). However, TURP is associated with a risk of complications, so minimally invasive methods have been developed. Prostate artery embolization (PAE) is a new minimally invasive procedure. This study reports the outcomes of PAE when introduced in a 'real life' clinical setting in a Swedish County hospital. Methods: A prospective, single-center, single-arm study in a consecutive vascular-anatomy 'all comers' population, eligible for TURP or adenomaenukleation, but unsuitable for this, treated with PAE from January 2015 to June 2018. Defined improvement of IPSS/QoL scores, or freedom from urinary catheter if previous urinary catheter-dependent, or clean intermittent catheterization (CIC) were considered as clinically successful treatments. PAE was performed until arterial stasis using the Perfected technique. Most patients were treated during a day-care procedure. Results: Of 37 treated men, bilateral PAEs were achieved in 32 patients, unilateral PAEs in four patients, and bilateral failure in one patient due to difficult vascular anatomy. Clinically successful treatment was achieved in 84%, without serious adverse events. Conclusions: PAE was introduced in Sweden, showing PAE as a novel and good minimally invasive alternative in treatment of symptomatic BPH, possible to perform as a day-care procedure.

Abstract
PURPOSE To identify technical factors that significantly change prostatic artery embolization (PAE) technical outcomes and to derive and test technical outcome predictive models. MATERIALS AND METHODS Retrospective analysis of PAEs performed by 2 operators (OPs) was performed: OP1, between April 2014 and May 2017 (n = 150); OP2, between February 2017 and December 2017 (n = 67). Multivariate analysis with mixed-effects modeling was used to test significance and derive predictive models. Mean difference was used to analyze prediction accuracy. RESULTS Moderate versus none subjective iliac tortuosity grade (SITG) and the presence of internal iliac atherosclerosis (PIIAA) versus none were associated with the following respective technical outcome increases: procedure time (PT): 43% (P < .01), 16% (P < .01); fluoroscopy time (FT): 47% (P < .01), 25% (P < .01); contrast volume (CV): 25.6 mL (P < .001), 13.7 mL (P = .01); and dose area product (DAP) 52% (P < .01), 20% (P = 0.03). Prostatic artery origin left obturator versus left superior vesical was associated with a 24% (P = .01) DAP decrease. For every 1 cc that prostate volume increased, CV decreased on average by 0.1 mL (P = .05). For every 1-cm decrease in patient height and 1-kg increase in weight, DAP increased on average by 0.02% (P < .01) for each. Unilateral versus bilateral versus 3-vessel embolization resulted in a 16.3-mL CV decrease on average for each additional vessel embolized (P = .03). The mean absolute differences between predicted and measured technical outcome values were: PT: 16 minutes, FT: 7 minutes, CV: 25 mL, and DAP: 44 Gy·cm2. CONCLUSIONS In this study, higher SITGs and PIIAA most likely contributed to higher technical outcomes when controlling for the 2 OPs.

Abstract
Nearly one in three men develop lower urinary tract symptoms (LUTS) and 10% clinically progress despite medication. Transurethral resection of the prostate (TURP) is the reference standard for symptoms refractory to medical treatment. However, some patients cannot tolerate TURP for medical (e.g., comorbidity) or technical (e.g., large prostate) reasons. This study estimated the safety and effect of prostate artery embolization (PAE) in men unfit for surgery. A prospective, single-centre trial including men with LUTS or urinary retention secondary to benign prostatic hyperplasia (BPH) who were unfit for surgery. The primary objective was to treat urinary retention and LUTS. Outcome measures included International Prostate Symptom Score (IPSS), quality of life (IPSS-QoL), International Index of Erectile Function (IIEF-5), prostate volume (PV), prostate-specific antigen (PSA), peak void flow (Qmax), post-void residual (PVR), and complications. A p-value < 0.05 was considered statistically significant. Eleven consecutive patients with a mean age of 75.2 (SD ± 8.2) underwent PAE. Catheter removal was successful in 60%. IPSS-QoL improved 4.5 points (95% CI: -5.6; -3.4), and PV was reduced by 26.2 cm3 (95% CI: -50.9; -2.3). None of the remaining outcomes changed. No major complications occurred. PAE was effective and safe for LUTS and urinary retention associated with BPH in men unfit for surgery.

Abstract
PURPOSE To determine the effects of prostatic artery embolization (PAE) on prostatic elasticity as assessed by Ultrasound Elastography (US-E), as well as to describe the feasibility and role of US-E as a novel tool in both pre- and post-PAE evaluation. MATERIALS AND METHODS This is a prospective, single-center investigation that included eight patients undergoing PAE for treatment of lower urinary tract symptoms (LUTS) attributed to benign prostate hyperplasia (BPH). Baseline and 3-month follow-up evaluations were performed and included prostate-specific antigen (PSA), uroflowmetry, pelvic magnetic resonance imaging and clinical assessment using the International Prostate Symptom Score (IPSS) questionnaire and the IPSS-Quality of life (QoL) item. US-E with measurement of the prostatic Elastic Modulus (EM) was performed before PAE and at 1-month follow-up. RESULTS After PAE, US-E showed a significant reduction of prostatic EM as assessed in kPa (33.14 vs. 47.24, - 29.8%, p = 0.002) and in m/s (3.75 vs. 4.63, - 19.0%, p < 0.001). Also, the transitional/peripheral zone ratio was significantly reduced by 45.36% (0.53 vs. 0.97, p < 0.05). All eight patients presented with significant LUTS improvement after PAE (p < 0.05 for IPSS, QoL, prostate volume, peak urinary flow rate and PSA). CONCLUSIONS Findings described in this study suggest that PAE significantly reduces prostatic EM, leading to a positive effect on BPH dynamic component related to prostatic elasticity. Also, it features US-E as an additional tool for pre- and post-PAE evaluation, describing a novel indication for this technology.

Optimized protocol of multiple post-processing techniques improves diagnostic accuracy of multidetector computed tomography in assessment of small bowel obstruction compared with conventional axial and coronal reformations. World J Gastroenterol 2019; 25:1100-1115. [PMID: 30862998 PMCID: PMC6406184 DOI: 10.3748/wjg.v25.i9.1100] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2018] [Revised: 02/13/2019] [Accepted: 02/16/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Axial and coronal reformations have been a widely used image post-processing protocol for the ordinary multidetector computed tomography (MDCT) examination of patients with small bowel obstruction (SBO) or other abdominal diseases. The diagnostic accuracy of MDCT for assessing SBO is expected to be further improved through the use of multiple post-processing techniques.
AIM To systemically evaluate the diagnostic accuracy and efficiency of an optimized protocol using multiple post-processing techniques for MDCT assessment of SBO and secondary bowel ischemia.
METHODS This retrospective cross-sectional study included 106 patients with clinically suspected SBO. Two readers applied three protocols to image post-processing and interpretation of patients’ MDCT volume data. We compared the three protocols based on time spent, number of images, diagnostic self-confidence, agreement, detection rate, and accuracy of detection of SBO and secondary bowel ischemia.
RESULTS Protocol 2 resulted in more time spent and number of images than protocols 1 and 3 (P < 0.01), but the results of the two readers using the same protocol were not different (P > 0.05). Using protocol 3, both readers added multiple post-processing techniques at frequencies of 29.2% and 34.9%, respectively, for obstruction cause, and 32.1% and 30.2%, respectively, for secondary bowel ischemia. Protocols 2 and 3 had higher total detection rates of obstruction cause and secondary bowel ischemia than protocol 1 (P < 0.01), but no difference was detected between protocols 2 and 3 (P > 0.05). The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of protocols 2 and 3 were superior to those of protocol 1 for evaluating obstruction cause and secondary bowel ischemia.
CONCLUSION Our optimized protocol of multiple post-processing techniques can both guarantee efficiency and improve diagnostic accuracy of MDCT for assessing SBO and secondary bowel ischemia.

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
Background To compare the clinical efficiency and safety of transurethral resection of the prostate (TURP) and prostatic artery embolization (PAE) for the treatment of Benign prostatic hyperplasia (BPH). Methods We searched PUBMED, EMBASE and the Cochrane Central Register for studies from May 1998 to May 2018 for studies comparing the efficiency and safety of TURP with PAE. Four studies met the inclusion criteria for our meta-analysis. After data extraction and quality assessment, we used RevMan 5.2 to pool the data. Results A total of four studies involving 506 patients were included in our meta-analysis. The pooled data showed that the Qmax was higher in TURP group than PAE with a significant difference (WMD:4.66, 95%CI 2.54 to 6.79, P < 0.05). The postoperative QOL was lower in the TURP than PAE group (WMD: -0.53, 95%CI -0.88 to − 0.18, P < 0.05). The postoperative prostate volume was significantly smaller in the TURP than PAE group (WMD: -8.26, 95%CI -12.64 to − 3.88, P < 0.05). The operative time was significantly shorter in the TURP than PAE group (WMD: -10.55, 95%CI -16.92 to − 4.18, P < 0.05). No significant difference was found in the postoperative IPSS and complications between TURP and PAE (P > 0.05, WMD:1.56, 95%CI -0.67 to 3.78, p = 0,05, OR:1.54, 95%CI 1.00 to2.38, respectively). Conclusions TURP could achieve improved Qmax and QoL compared to PAE. Therefore, for patients with BPH and lower urinary tract symptoms (LUTS), TURP was superior to PAE.

Abstract
Manganese-enhanced magnetic resonance imaging (MEMRI) is based on neuronal activity-dependent manganese uptake, and provides information about nervous system function. However, systematic studies of pain processing using MEMRI are rare, and few investigations of pain using MEMRI have been performed in the spinal cord. Herein, we investigated the pain dependence of manganese ions administered in the rat spinal cord. MnCl2 was administered into the spinal cord via an intrathecal catheter before formalin injection into the right hind paw (50 μL of 5% formalin). The duration of flinching behavior was recorded and analyzed to measure formalin-induced pain. After the behavioral test, rats were sacrificed with an overdose of urethane (50 mg/kg), and spine samples were extracted and post-fixed in 4% paraformaldehyde solution. The samples were stored in 30% sucrose until molecular resonance (MR) scanning was performed. In axial Mn2+ enhancement images of the spinal cord, Mn2+ levels were found to be significantly elevated on the ipsilateral side of the spinal cord in formalin-injected rats. To confirm pain-dependent Mn enhancement in the spinal cord, c-Fos expression was analyzed, and was found to be increased in the formalin-injected rats. These results indicate that MEMRI is useful for functional analysis of the spinal cord under pain conditions. The gray matter appears to be the focus of intense paramagnetic signals. MEMRI may provide an effective technique for visualizing activity-dependent patterns in the spinal cord.

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 Minimally invasive alternatives to transurethral resection of the prostate (TURP) such as prostate arterial embolization (PAE) and photoselective vaporization of the prostate (PVP) are being explored as adjuncts in the care of patients with benign prostatic hyperplasia. However, there are conflicting reports of the costs of these procedures. The purpose of this study was to compare the direct and indirect hospital costs of TURP, PAE and PVP. MATERIALS AND METHODS A chart review was performed in patients who underwent TURP, PVP and PAE from April 2015 to March 2017. All hospital costs were collected in accordance with the Ontario Case Costing Initiative, a standardized medical case costing system. Costs were characterized as direct or indirect and fixed or variable. Probabilistic sensitivity analysis was conducted to study cost uncertainty. RESULTS During the study period, a total of 209 men underwent TURP, 28 PVP and 21 PAE. Mean age (years) was as follows: TURP 71.43; PVP 73.66; PAE 70.77 (p = 0.366). Mean length of stay (days) was as follows: TURP 1.63; PVP 1.55; PAE 1 (p = 0.076). Total costs of the PAE group ($3829, SD $1582) were less than both PVP ($5719, SD $1515) and TURP groups ($5034, SD $1997, p < 0.001). There was no significant difference in direct costs between the groups. Monte Carlo simulation demonstrated that PAE was the least costly alternative majority of the time. CONCLUSIONS The total hospital costs of PAE at our institution are significantly lower than those of PVP and TURP.

Evaluation of the NMR-MOUSE as a new method for continuous functional monitoring of the small intestine during different perfusion states in a porcine model. PLoS One 2018; 13:e0206697. [PMID: 30388139 PMCID: PMC6214547 DOI: 10.1371/journal.pone.0206697] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Accepted: 10/17/2018] [Indexed: 12/31/2022] Open
Abstract
Objective The study aim was to evaluate a small low-field NMR (nuclear magnetic resonance) scanner, the NMR-MOUSE®, for detecting changes in intestinal diffusion under different (patho-) physiological perfusion states. Methods Laparotomy was performed on 8 female landrace pigs (body weight 70±6 kg) and the feeding vessels of several intestinal loops were dissected. Successively, the intestinal loops were examined using O2C (oxygen to see, LEA Medizintechnik GmbH, Giessen, Germany) for microcirculatory monitoring and the NMR-MOUSE® for diffusion measurement (fast and slow components). On each loop the baseline measurement (physiological perfusion) was followed by one of the following main procedures: method 1 –ischemia; method 2 –flow reduction; method 3 –intraluminal glucose followed by ischemia; method 4 –intraluminal glucose followed by flow reduction. Additionally, standard perioperative monitoring (blood pressure, ECG, blood gas analyses) and histological assessment of intestinal biopsies was performed. Results There was no statistical overall time and method effect in the NMR-MOUSE measurement (fast component: ptime = 0.6368, pmethod = 0.9766, slow component: ptime = 0.8216, pmethod = 0.7863). Yet, the fast component of the NMR-MOUSE measurement showed contrary trends during ischemia (increase) versus flow reduction (decrease). The slow-to-fast diffusion ratio shifted slightly towards slow diffusion during flow reduction. The O2C measurement showed a significant decrease of oxygen saturation and microcirculatory blood flow during ischemia and flow reduction (p < .0001). The local microcirculatory blood amount (rHb) showed a significant mucosal increase (pClamping(method 1) = 0.0007, pClamping(method 3) = 0.0119), but a serosal decrease (pClamping(method 1) = 0.0119, pClamping(method 3) = 0.0078) during ischemia. The histopathological damage was significantly higher with increasing experimental duration and at the end of methods 3 and 4 (p < .0001,Fisher-test). Conclusion Monitoring intestinal diffusion changes due to different perfusion states using the NMR-MOUSE is feasible under experimental conditions. Despite the lack of statistical significance, this technique reflects perfusion changes and therefore seems promising for the evaluation of different intestinal perfusion states in the future. Beforehand however, an optimization of this technology, including the optimization of the penetration depth, as well as further validation studies under physiological conditions and including older animals are required.

Abstract
INTRODUCTION AND OBJECTIVE Surgical management of benign prostatic hyperplasia has dramatically changed in the recent years towards higher proportion of endoscopic treatment and fewer perioperative complications. Nevertheless the question of urinary and sexual quality of life after surgical treatment remains partially unresolved with a high proportion of retrograde ejaculation after conventional surgical treatments. Therefore mini-invasive alternatives to conventional surgery have been proposed. The objective of this literature review was to provide an overview of the alternatives to monopolar TURP currently available in France. MATERIAL AND METHOD A non-systematic review of the scientific literature was conducted from the PubMed database to retrieve the most relevant scientific publications. A first research was cross-referenced with the results of literature reviews already published and enriched by the authors of this review. A synthesis is proposed for each alternative technique mentioning its level of clinical development, but also its potential advantages and disadvantages compared to conventional surgical techniques. RESULTS The quality of life of patients after surgical or interventional management has become the main priority of urologists since the risks of perioperative complication have been reduced by the use of laser or bipolar endoscopic techniques. Thanks to the development of minimally invasive alternatives that are better and better evaluated by randomized trials versus interventional simulation and conventional surgical treatment, more personalized care is possible. Patients' expectations and their individual risk factors can thus be placed at the center of the therapeutic decision and the preoperative information. CONCLUSION The surgical and interventional management of LUTS due to BPH has evolved to lower perioperative morbidity with the help of numerous technological developments. Mini-invasive alternatives to standard treatment have also been proposed in order to improve the quality of postoperative sexual life. These alternatives provide significant improvement in LUTS that remains lower than after conventional treatments. Somme of these alternative are also not fully supported by clinical trials, which should urge urologists to act with caution when proposing these alternatives in daily clinical practice.

Abstract
PURPOSE To evaluate the safety and efficacy of prostatic artery embolization (PAE) using the combination of 50-μm and 100-μm polyvinyl alcohol (PVA) particles versus 100-μm PVA particles alone in the treatment of patients with symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS Over a 5-year period, 120 patients treated with PAE for lower urinary tract symptoms (LUTS) secondary to BPH were randomized to undergo embolization with 50-μm plus 100-μm PVA particles (group A) or 100-μm PVA particles alone (group B). Mean follow-up time was 34 months (range, 12-57 mo). There were no differences between groups regarding baseline data. Primary outcome measurements included change in International Prostate Symptom Score (IPSS) and incidence of adverse events. Secondary outcome measurements included procedure-associated pain, prostate ischemia measured on magnetic resonance (MR) imaging 1 week after PAE, and changes over time in quality of life (QOL) questionnaire, peak urinary flow rate (Qmax), postvoid residual (PVR) volume, prostate volume (PV), prostate-specific antigen (PSA) level, and International Index of Erectile Function (IIEF) were evaluated. Recurrence of LUTS following PAE was defined as relief of LUTS temporally but increased IPSS ≥ 8 or QOL score ≥ 3 or decrease in Qmax to < 7 mL/s. RESULTS Mean follow-up periods were 35 months ± 22 in group A and 33 months ± 25 in group B (P = .629). No differences between groups regarding procedural details, pain scores, or adverse events were noted (P > .05). At 24 month of follow-up, patients in group A had a greater decrease in mean IPSS (18.7 ± 12.5 vs 14.8 ± 13.5), QOL score (3.7 ± 1.5 vs 2.4 ± 1.8), Qmax (10.5 mL ± 9.5 vs 6.8 mL ± 5.0), PVR (92.0 mL ± 75.0 vs 60.0 mL ± 55.0), and PV (37.0 mL ± 19.5 vs 25.5 mL ± 15.0) compared with patients in group B (P < .05 for all). Mean ratios of prostate ischemic volume at 1 week after PAE were 70% ± 20 in group A and 41% ± 25 in group B (P = .021); mean PSA levels at 24 hour after PAE were 92.5 ng/mL ± 55.0 in group A and 77.5 ng/mL ± 45.0 in group B (P = .031); LUTS recurrence rates were 3.6% in group A and 14.6% in group B (P = .024). The mean IIEF-5 was not significantly different from baseline in either group. CONCLUSIONS PAE with 50-μm plus 100-μm PVA particles resulted in greater improvement in clinical and imaging outcomes and no significant differences in adverse events compared with 100-μm PVA particles alone.

Abstract
CONTEXT Prostatic artery embolization (PAE) has been introduced into clinical practice for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH-LUTS) despite a lack of high-level evidence. OBJECTIVE To perform a systematic review and meta-analysis of clinical trials comparing efficacy and safety of PAE versus established surgical therapies. EVIDENCE ACQUISITION Medline, Embase, and York CRD were searched up to June 23, 2018. Only comparative studies were included. The risk of bias was assessed by the Cochrane Collaboration tool. Meta-analyses were performed using RevMan 5.3. EVIDENCE SYNTHESIS Five studies including 708 patients met the selection criteria. Risk of bias was rated high for most of the studies. Mean reduction in the International Prostate Symptom Score was lower after PAE compared with standard surgical therapies (mean difference 3.80 points [95% confidence interval: 2.77-4.83]; p<0.001). PAE was less efficient regarding improvements in all functional parameters assessed including maximum urinary flow, post void residual, and reduction of prostate volume. In contrast, patient-reported erectile function (International Index of Erectile Function 5) was better after PAE and significantly fewer adverse events occurred after PAE. CONCLUSIONS Moderately strong evidence confirms efficacy and safety of PAE in the treatment of BPH-LUTS in the short term. Significant advantages regarding safety and sexual function, but clear disadvantages regarding all other patient-reported and functional outcomes were found for PAE. Large-scale randomized controlled trials including longer follow-up periods are mandatory before PAE can be considered as a standard therapy and to define the ideal indication for PAE in the management of BPH-LUTS. PATIENT SUMMARY We reviewed the role of prostatic artery embolization (PAE) in the treatment of symptoms associated with benign overgrowth of the prostate. The results suggest that PAE is not as effective as established surgical therapies but has fewer side effects. Further research is required to determine whether PAE is the best treatment for certain types of patients. PAE should, therefore, not yet be considered a standard treatment.

Abstract
Jejunal obstruction due to a phytobezoar is clinically rare. A male patient was admitted to our hospital with abdominal pain. He suffered a very threatening process from diagnosis to surgery. Considering that this is a rare complication caused by common clinical diseases and is therefore vulnerable to delayed diagnosis and treatment, this case has good guiding significance for clinical gastroenterologists.

Abstract
BACKGROUND Ace-1 canine prostate cancer cells grow orthotopically in cyclosporine immunosuppressed laboratory beagles. We previously transfected (human Gastrin-Releasing Peptide Receptor, huGRPr) into Ace-1 cells and demonstrated receptor-targeted NIRF imaging with IR800-G-Abz4-t-BBN, an agonist to huGRPr. Herein, we used the new cell line to develop the first canine prostate cancer model expressing a human growth factor receptor. METHODS Dogs were immunosuppressed with cyclosporine, azathioprine, prednisolone, and methylprednisolone. Their prostate glands were implanted with Ace-1huGRPr cells. The implantation wounds were sealed with a cyanoacrylic adhesive to prevent extraprostatic tumor growth. Intraprostatic tumors grew in 4-5 week. A lobar prostatic artery was then catheterized via the carotid artery and 25-100 nmol IR800-Abz4-t-BBN was infused in 2 mL followed by euthanasia in dogs 1-2, and recovery for 24 h before euthanasia in dogs 3-6. Excised tissues were imaged optically imaged, and histopathology performed. RESULTS Dog1 grew no tumors with cyclosporine alone. Using the four drug protocol, Dogs 2-6 grew abundant 1-2 mm intracapsular and 1-2 cm intraglandular tumors. Tumors grew >5 cm when the prostate cancer cells became extracapsular. Dogs 4-6 with sealed prostatic capsule implantation sites had growth of intracapsular and intraglandular tumors and LN metastases at 5 weeks. High tumor to background BPH signal in the NIRF images of sectioned prostate glands resulted from the 100 nmol dose (∼8 nmol/kg) in dogs 2-4 and 50 nmol dose in dog 5, but not from the 25 nmol dose in Dog 6. Imaging of mouse Ace-1huGRPr tumors required an intravenous dose of 500 nmol/kg body wt. A lymph node that drained the prostate gland was detectable in Dog 4. Histologic findings confirmed the imaging data. CONCLUSION Ace-1huGRPr cells created viable, huGRPr-expressing tumors when implanted orthotopically into immune-suppressed dogs. Local delivery of an imaging agent through the prostatic artery allowed a very low imaging dose, suggesting that therapeutic agents could be used safely for treatment of early localized intraglandular prostate cancer as adjuvant therapy for active surveillance or focal ablation therapies, or for treating multifocal intraglandular disease where focal ablation therapies are not indicated or ineffective.

Abstract
OBJECTIVE To compare prostatic artery embolisation (PAE) with transurethral resection of the prostate (TURP) in the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia in terms of patient reported and functional outcomes. DESIGN Randomised, open label, non-inferiority trial. SETTING Urology and radiology departments of a Swiss tertiary care centre. PARTICIPANTS 103 patients aged ≥40 years with refractory lower urinary tract symptoms secondary to benign prostatic hyperplasia were randomised between 11 February 2014 and 24 May 2017; 48 and 51 patients reached the primary endpoint 12 weeks after PAE and TURP, respectively. INTERVENTIONS PAE performed with 250-400 μm microspheres under local anaesthesia versus monopolar TURP performed under spinal or general anaesthesia. MAIN OUTCOMES AND MEASURES Primary outcome was change in international prostate symptoms score (IPSS) from baseline to 12 weeks after surgery; a difference of less than 3 points between treatments was defined as non-inferiority for PAE and tested with a one sided t test. Secondary outcomes included further questionnaires, functional measures, magnetic resonance imaging findings, and adverse events; changes from baseline to 12 weeks were compared between treatments with two sided tests for superiority. RESULTS Mean reduction in IPSS from baseline to 12 weeks was -9.23 points after PAE and -10.77 points after TURP. Although the difference was less than 3 points (1.54 points in favour of TURP (95% confidence interval -1.45 to 4.52)), non-inferiority of PAE could not be shown (P=0.17). None of the patient reported secondary outcomes differed significantly between treatments when tested for superiority; IPSS also did not differ significantly (P=0.31). At 12 weeks, PAE was less effective than TURP regarding changes in maximum rate of urinary flow (5.19 v 15.34 mL/s; difference 10.15 (95% confidence interval -14.67 to -5.63); P<0.001), postvoid residual urine (-86.36 v -199.98 mL; 113.62 (39.25 to 187.98); P=0.003), prostate volume (-12.17 v -30.27 mL; 18.11 (10.11 to 26.10); P<0.001), and desobstructive effectiveness according to pressure flow studies (56% v 93% shift towards less obstructive category; P=0.003). Fewer adverse events occurred after PAE than after TURP (36 v 70 events; P=0.003). CONCLUSIONS The improvement in lower urinary tract symptoms secondary to benign prostatic hyperplasia seen 12 weeks after PAE is close to that after TURP. PAE is associated with fewer complications than TURP but has disadvantages regarding functional outcomes, which should be considered when selecting patients. Further comparative study findings, including longer follow-up, should be evaluated before PAE can be considered as a routine treatment. TRIAL REGISTRATION Clinicaltrials.gov NCT02054013.

Prostatic Artery Embolization with 250-μm Spherical Polyzene-Coated Hydrogel Microspheres for Lower Urinary Tract Symptoms with Follow-up MR Imaging. J Vasc Interv Radiol 2018; 29:1127-1137. [PMID: 29910163 DOI: 10.1016/j.jvir.2018.03.014] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Revised: 03/01/2018] [Accepted: 03/02/2018] [Indexed: 01/10/2023] Open
Abstract
PURPOSE To evaluate clinical outcomes and possible MR imaging predictors of clinical success after prostatic artery embolization (PAE) with 250-μm hydrogel particles. MATERIALS AND METHODS During a span of 1.5 years, 30 patients with moderate to severe lower urinary tract symptoms were included in a prospective, nonrandomized study. Embolization of at least one prostatic artery was considered as technical success. International Prostate Symptom Score (IPSS), quality of life (QOL), peak urinary flow rate (Qmax), residual urine volume, prostate volume, prostate-specific antigen level, and International Index of Erectile Function (IIEF) were recorded at baseline and at 1, 3, and 6 months after PAE. Multiparametric MR imaging was performed before PAE (n = 25) and 1 day (n = 25), 1 month (n = 7), 3 months (n = 7), and 6 months (n = 22) after intervention. A Wilcoxon-Mann-Whitney test was used to assess changes over time, and Spearman rank-correlation coefficient was used for outcome prediction. RESULTS PAE was technically successful in 90% of patients (n = 27). Clinical success (IPSS < 18 with decrease > 25% and QOL score < 4 with decrease ≥ 1 or Qmax ≥ 15 mL/s and increase of ≥ 3.0 mL/s) rates were 59% (16 of 27), 63% (17 of 27), and 74% (20 of 27) after 1, 3, and 6 mo, respectively. IIEF scores did not differ significantly during follow-up. The following adverse events occurred after PAE: urethral burning (5 of 27), fever (2 of 27), and urethral bleeding, rectal bleeding, cystitis, and penile burning sensation (1 of 27 each). No statistical correlations between initial multiparametric MR imaging changes and clinical parameters after 6 months were found (P values from .14 to .98). CONCLUSIONS PAE with 250-μm hydrogel microspheres led to good clinical success after 6 months with a low complication rate. Significant MR imaging predictors of clinical success were not identified.
