Abstract
RATIONALE AND OBJECTIVES The long-term effectiveness of prostatic artery embolization (PAE) can be hampered by the recanalization of the previously embolized prostatic arteries (PA). The use of a liquid embolic agent (LEA) could limit this risk. The purpose of this study was to assess the safety and efficacy of repeat PAE (rePAE) using a LEA (Squid Peri) coupled with microspheres in patients experiencing recurring symptoms after initial embolization. MATERIALS AND METHODS This retrospective single-center study included all consecutive patients who underwent rePAE using Squid Peri coupled with microspheres. Angiographic patterns of prostatic revascularization were identified. Outcomes were assessed at the 3-month follow-up using the International Prostate Symptom Score (IPSS) and the Quality of Life (QoL) score. The primary endpoint was clinical success defined as an IPSS < 18 with > 25% decrease and a QoL score ≤ 3 with ≥ 1 point decrease. Safety was assessed by using the modified Clavien-Dindo classification. RESULTS 30 consecutive men (mean age: 67.1 ± 9.5 years) were included. Recanalization of the previously embolized PA was found in 83.3% of patients. Technical success was 93.3%. Median follow-up was 4.9 months [IQR: 3.9 - 9.8]. Clinical success rate was 76.7%, with a mean decrease in IPSS of -9.3 ± 7.3 (p < 0.001) and a median decrease in QoL of -2 [IQR: - 4 - - 1] (p < 0.001). One patient presented with an acute urinary retention requiring readmission (grade IIIa complication). CONCLUSION Repeat PAE using Squid Peri coupled with microspheres is safe and effective for patients with recurring symptoms after initial embolization.

Abstract
Knowledge about anatomical details seems to facilitate the procedure and planning of prostatic artery embolization (PAE) in patients with symptomatic benign prostatic hyperplasia (BPS). The aim of our study was the pre-interventional visualization of the prostatic artery (PA) with MRA and the correlation of iliac elongation and bifurcation angles with technical success of PAE and technical parameters. MRA data of patients with PAE were analysed retrospectively regarding PA visibility, PA type, vessel elongation, and defined angles were correlated with intervention time, fluoroscopy time, dose area product (DAP), cumulative air kerma (CAK), contrast media (CM) dose and technical success of embolization. T-test, ANOVA, Pearson correlation, and Kruskal-Wallis test was applied for statistical analysis. Between April 2018 and March 2021, a total of 78 patients were included. MRA identified the PA origin in 126 of 147 cases (accuracy 86%). Vessel elongation affected time for catheterization of right PA (p = 0.02), fluoroscopy time (p = 0.05), and CM dose (p = 0.02) significantly. Moderate correlation was observed for iliac bifurcation angles with DAP (r = 0.30 left; r = 0.34 right; p = 0.01) and CAK (r = 0.32 left; r = 0.36 right; p = 0.01) on both sides. Comparing the first half and second half of patients, median intervention time (125 vs. 105 min.) and number of iliac CBCT could be reduced (p < 0.001). We conclude that MRA could depict exact pelvic artery configuration, identify PA origin, and might obviate iliac CBCT. Vessel elongation of pelvic arteries increased intervention time and contrast media dose while the PA origin had no significant influence on intervention time and/or technical success.

Abstract
PURPOSE The purpose of this study was to assess the feasibility, safety, and 6-month outcomes of prostate artery embolization (PAE) using N-butyl-cyanoacrylate (NBCA) glue as the only embolic agent in patients with benign prostatic hyperplasia (BPH)-related lower urinary tract symptoms. MATERIALS AND METHODS Patients with BPH-related lower urinary tract symptoms who were treated by PAE using methacryloxysulfolane-NBCA mixed with ethiodized oil (1:8 ratio) between September 2018 and January 2023 were retrospectively included. Vascular mapping was made using cone-beam computed tomography angiography. PAEs were performed as an outpatient procedure, under local anaesthesia. Outcomes were assessed at six months using the International Prostate Symptoms Score (IPSS) and associated quality-of-life score (IPSS-QoL), prostate-specific antigen (PSA) level, prostate volume, and International Index of Erectile Function form 5 (IIEF5). RESULTS A total of 103 men with a mean age of 68.4 ± 6 (standard deviation [SD]) years were included. Technical success rate was 100%. The mean fluoroscopy time was 26.4 ± 12.5 (SD) min and the median radiation dose was 23 980 mGy·cm (Q1, Q3: 16 770, 38 450). Compared to baseline, statistically significant improvements were observed at six months for the IPSS (8.9 ± 6.2 [SD] vs. 20.2 ± 6.5 [SD]; P = 0.01), IPSS-QoL (2.1 ± 1.4 [SD] vs. 5.1 ± 0.9 [SD]; P = 0.01), PSA level (3.6 ± 3.2 [SD] ng/mL vs. 4.8 ± 4.2 [SD] ng/mL; P = 0.0001), and prostate volume (78.6 ± 43.5 [SD] mL vs. 119.1 ± 65.7 [SD] mL; P = 0.01). Minor adverse events developed in 19/103 (18.4%) patients. No major complications occurred. Compared to baseline, the IIEF5 did not change significantly at six months (15.3 ± 6.8 [SD] vs. 15.8 ± 6.8 [SD]; P = 0.078). CONCLUSION PAE with NBCA is a feasible and safe method that provides good outcomes at six months in patients with BPH-related lower urinary tract symptoms. This method deserves further evaluation in randomized trials with longer follow-up.

Abstract
PURPOSE To compare prostatic artery embolization (PAE) via transradial access (TRA-PAE) versus transfemoral access (TFA-PAE) to assist access selection. MATERIAL AND METHODS Procedural outcomes and adverse events were evaluated in 998 patients who underwent PAE at a single center from April 2014 to August 2022; 821 (82%) underwent TRA-PAE (Group R) and 177 (18%) underwent TFA-PAE (Group F). Mean age and prostate size of Groups R and F were 69.2 years (SD ± 8.4) and 117.4 g (SD ± 63.1) and 75.2 years (SD ± 12.1) and 127.2 g (SD ± 83.6), respectively (P < .01 and P = .16; postpropensity matching: P = .38 and P = .35, respectively). Indications for PAE included lower urinary tract symptoms, acute or chronic urinary retention, and hematuria. Procedural and patient-specific metrics were reviewed. Technical success was defined as bilateral PAE. Adverse events were recorded according to the Society of Interventional Radiology (SIR) adverse events classification. Statistical significance was defined as P < .05. RESULTS Technical success was achieved in 798 (97.2%) patients in Group R and 165 (93.2%) patients in Group F. Mean procedural time, single- and continuous-rotation fluoroscopy time, dose area product, and air kerma were significantly lower in Group R than in Group F (P < .001). Moreover, 6 (0.7%) patients in Group R and 9 (5.5%) patients in Group F had access site ecchymoses, whereas 5 (0.6%) patients in Group R and 6 (3.6%) in Group F had access site hematomas. Two patients experienced transient ischemic attacks (TIAs) after TRA-PAE and recovered without intervention. Two occult radial artery occlusions were noted, but no patient experienced hand ischemia. CONCLUSIONS In a large single interventional radiologist cohort, TRA-PAE demonstrated similar technical success to that of TFA-PAE with lower access site hemorrhagic complications and radiation requirements; however, TIA and occult radial artery occlusions remain a concern.

Abstract
PURPOSE This study aimed to assess the clinical outcome and safety of holmium laser enucleation of the prostate (HoLEP) following transrectal ultrasound-guided prostate biopsy (TR biopsy) in the treatment of benign prostate hyperplasia. MATERIALS AND METHODS We retrospectively analyzed data from 556 patients who underwent HoLEP between 2014 and 2021. The patients were categorized into six groups: Group 1-A (n=45) underwent HoLEP within four months post TR biopsy. Group 1-B (n=94) underwent HoLEP more than four months post TR biopsy. Group 1-C (n=120) underwent HoLEP after a single TR biopsy. Group 1-D (n=19) underwent HoLEP after two or more TR biopsies. Group 1-total (n=139, group 1-A+group 1-B or group 1-C+group 1-D) underwent HoLEP post TR biopsy. Group 2 (control group, n=417) underwent HoLEP without prior TR biopsy. We examined perioperative parameters, safety, and functional outcomes. RESULTS The age, body mass index, International Prostate Symptom Score (IPSS), uroflowmetry, and comorbid diseases between group 1-total and group 2 were comparable. However, group 1-total exhibited significantly elevated prostate-specific antigen levels and larger prostate volumes (p<0.01). Perioperative factors like enucleation time, enucleation weight, and catheterization duration were notably higher in group 1-total (p<0.01). All groups showed significant improvements in IPSS, postvoid residual urine, and maximum flow rate during the 1-year postoperative period (p<0.05). The rates of postoperative complications were similar between group 1-total and group 2. CONCLUSIONS Enucleation time and catheterization duration were significantly longer in the TR biopsy group. However, postoperative complications were not significantly different between TR biopsy and non-TR biopsy groups.

Abstract
Background Prostatic artery embolization (PAE) is a safe, minimally invasive angiographic procedure that effectively treats benign prostatic hyperplasia; however, PAE-related patient radiation exposure and associated risks are not completely understood. Purpose To quantify radiation dose and assess radiation-related adverse events in patients who underwent PAE at multiple centers. Materials and Methods This retrospective study included patients undergoing PAE for any indication performed by experienced operators at 10 high-volume international centers from January 2014 to May 2021. Patient characteristics, procedural and radiation dose data, and radiation-related adverse events were collected. Procedural radiation effective doses were calculated by multiplying kerma-area product values by an established conversion factor for abdominopelvic fluoroscopy-guided procedures. Relationships between cumulative air kerma (CAK) or effective dose and patient body mass index (BMI), fluoroscopy time, or radiation field area were assessed with linear regression. Differences in radiation dose stemming from radiopaque prostheses or fluoroscopy unit type were assessed using two-sample t tests and Wilcoxon rank sum tests. Results A total of 1476 patients (mean age, 69.9 years ± 9.0 [SD]) were included, of whom 1345 (91.1%) and 131 (8.9%) underwent the procedure with fixed interventional or mobile fluoroscopy units, respectively. Median procedure effective dose was 17.8 mSv for fixed interventional units and 12.3 mSv for mobile units. CAK and effective dose both correlated positively with BMI (R2 = 0.15 and 0.17; P < .001) and fluoroscopy time (R2 = 0.16 and 0.08; P < .001). No radiation-related 90-day adverse events were reported. Patients with radiopaque implants versus those without implants had higher median CAK (1452 mGy [range, 900-2685 mGy] vs 1177 mGy [range, 700-1959 mGy], respectively; P = .01). Median effective dose was lower for mobile than for fixed interventional systems (12.3 mSv [range, 8.5-22.0 mSv] vs 20.4 mSv [range, 13.8-30.6 mSv], respectively; P < .001). Conclusion Patients who underwent PAE performed with fixed interventional or mobile fluoroscopy units were exposed to a median effective radiation dose of 17.8 mSv or 12.3 mSv, respectively. No radiation-related adverse events at 90 days were reported. © RSNA, 2024 See also the editorial by Mahesh in this issue.

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
OBJECTIVE To assess the performance of apparent diffusion coefficient (ADC; values or category) alone, Prostate Imaging Reporting and Data System version 2.1 (PI-RADS v2.1) scoring alone, and the two in combination, to diagnose transition zone prostate cancers (PCas). METHODS This retrospective study included 222 patients who underwent multiparametric magnetic resonance imaging of the prostate between May 2020 and December 2022 and who had pathologically confirmed PCa or benign prostatic hyperplasia (BPH). Prostate Imaging Reporting and Data System version 2.1 and ADC (values or category) were used in the assessment of suspicious findings identified in the transition zone. The interobserver agreements for region-of-interest measurements were calculated by intraclass correlation coefficients. Logistic regression analyses were used to determine the performance of PI-RADS v2.1 alone and in combination with ADC (values or category) to diagnose PCa. Receiver operating characteristic curve and DeLong test were used to evaluate the diagnostic performance of the quantitative parameters. RESULTS A total of 152 patients had BPH, and 70 patients had PCa. For BPH versus PCa, the ADC values of PCa (0.64 × 10 -3 ± 0.16 × 10 -3 mm 2 /s) were significantly lower than BPH (1.06 ± 0.18 × 10 -3 mm 2 /s; P < 0.001). The PI-RADS scores for PCa (5 [interquartile range, 5-5]) were significantly higher than BPH (2 [interquartile range, 2-3]; P < 0.001). For all patients who had PI-RADS 1-5, the combined use of ADC (values or category) together with PI-RADS v2.1 did not perform significantly better than the use of PI-RADS v2.1 alone. The receiver operating characteristic of ADC category in combination with PI-RADS v2.1 score, 0.756 (95% confidence interval, 0.646-0.846), was significantly higher than that for PI-RADS 2.1 alone, 0.631 (95% confidence interval, 0.514-0.738), in PI-RADS 3-4 lesions ( P = 0.047). CONCLUSION The ADC category can help to improve the diagnostic performance of PI-RADS v2.1 category 3-4 lesions in diagnosing PCa.

Abstract
We aimed to evaluate the feasibility of MR elastography (MRE) using a transpelvic approach. Thirty-one patients who underwent prostate MRE and had a pathological diagnosis were included in this study. MRE was obtained using a passive driver placed at the umbilicus and iliac crests. The shear stiffness, clinical data, and conventional imaging findings of prostate cancer and benign prostatic hyperplasia (BPH) were compared. Inter-reader agreements were evaluated using the intraclass coefficient class (ICC). Prostate MRE was successfully performed for all patients (100% technical success rate). Nineteen cancer and 10 BPH lesions were visualized on MRE. The mean shear stiffness of cancer was significantly higher than that of BPH (5.99 ± 1.46 kPa vs. 4.67 ± 1.54 kPa, p = 0.045). One cancer was detected on MRE but not on conventional sequences. Six tiny cancer lesions were not visualized on MRE. The mean size of cancers that were not detected on MRE was smaller than that of cancers that were visible on MRE (0.8 ± 0.3 cm vs. 2.3 ± 1.8 cm, p = 0.001). The inter-reader agreement for interpreting MRE was excellent (ICC = 0.95). Prostate MRE with transpelvic vibration is feasible without intracavitary actuators. Transpelvic prostate MRE is reliable for detecting focal lesions, including clinically significant prostate cancer and BPH.

Abstract
Early detection of prostate cancer (PCa) and benign prostatic hyperplasia (BPH) is crucial for maintaining the health and well-being of aging male populations. This study aims to evaluate the performance of transfer learning with convolutional neural networks (CNNs) for efficient classification of PCa and BPH in transrectal ultrasound (TRUS) images. A retrospective experimental design was employed in this study, with 1380 TRUS images for PCa and 1530 for BPH. Seven state-of-the-art deep learning (DL) methods were employed as classifiers with transfer learning applied to popular CNN architectures. Performance indices, including sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), Kappa value, and Hindex (Youden's index), were used to assess the feasibility and efficacy of the CNN methods. The CNN methods with transfer learning demonstrated a high classification performance for TRUS images, with all accuracy, specificity, sensitivity, PPV, NPV, Kappa, and Hindex values surpassing 0.9400. The optimal accuracy, sensitivity, and specificity reached 0.9987, 0.9980, and 0.9980, respectively, as evaluated using twofold cross-validation. The investigated CNN methods with transfer learning showcased their efficiency and ability for the classification of PCa and BPH in TRUS images. Notably, the EfficientNetV2 with transfer learning displayed a high degree of effectiveness in distinguishing between PCa and BPH, making it a promising tool for future diagnostic applications.

Abstract
Background and Objectives: The purpose of the current paper is to present our study on the variability in the prostatic artery origin, discuss the less frequent origins, and present the challenges of the prostatic artery embolization (PAE) procedure, thus aiding young interventional radiologists. Materials and Methods: We studied the origins of the prostatic artery on digital subtraction angiography (DSA) examinations from PAE procedures on 35 male pelvises (70 hemi-pelvises). Results: Our study has demonstrated that the most frequent origin of the prostatic artery (PA) is the internal pudendal artery (IPA), 37.1%, followed by the anterior gluteal trunk, 27.1%, and the superior vesical artery (SVA), 21.4%. Less frequent origins are the obturator artery (OBT), 11.4%, and the inferior gluteal artery (IGA), 2.8%. Conclusions: Compared to other studies, we notice some differences in the statistical results, but the most frequent origins remain the same. What is more important for young interventional radiologists is to be aware of all the possible origins of the PA in order to be able to offer a proper treatment to their patients. The important aspect that will ensure the success of the procedure without post-procedural complications is represented by the successful embolization of the targeted prostatic parenchyma.

Abstract
PURPOSE Radical prostatectomy is one of the primary treatments for localized clinically significant prostate cancer. Generally, its application is based on prior biopsy. PSMA (prostate-specific membrane antigen)-PET (positron emission tomography) is considered promising in biopsy-free radical prostatectomy. The expression of PSMA in benign prostatic hyperplasia tissue and corresponding positive reaction are crucial concerns for a no-biopsy strategy. Currently, no study has explored the benign prostatic hyperplasia-related false-positive of PSMA-PET in the detection of prostate cancer. Furthermore, the influence of maximum standardized uptake value and Prostate Imaging Reporting & Data System on biopsy-free radical prostatectomy is also poorly characterized. MATERIALS AND METHODS A retrospective study was conducted on patients who received PSMA-PET because of clinical suspicion of prostate cancer and were confirmed to have benign prostatic hyperplasia or prostate cancer. The receiver operating characteristic curve was generated for maximum standardized uptake value. Results of interest were the false-positive rate of PSMA-PET and the efficacy of maximum standardized uptake value or multiparametric MRI in excluding false-positives. RESULTS The benign prostatic hyperplasia-related false-positive rate of PSMA-PET in detecting prostate cancer was 30%. Maximum standardized uptake value could effectively exclude benign prostatic hyperplasia and Grade Group 1 patients with an area under the curve of 0.86; the optimal maximum standardized uptake value cutoff value with 100% specificity was 15, with a sensitivity of 41%. Notably, the sensitivity and specificity of stringent PET score and Prostate Imaging Reporting & Data System criteria (both ≥4) in diagnosing clinically significant prostate cancer were 49% and 100%, respectively. CONCLUSIONS Our findings revealed benign prostatic hyperplasia-related false-positive rate of PSMA-PET and provided a preliminary reference in biopsy-free radical prostatectomy.

Abstract
PURPOSE To evaluate safety and effectiveness of prostatic artery embolization (PAE) using polyethylene glycol (PEG) microspheres in patients with moderate-to-severe benign prostatic hyperplasia (BPH). MATERIALS AND METHODS A single-center, prospective study of 30 patients who underwent PAE from August 2020 to December 2021 using PEG 400-μm microspheres was conducted. Patient evaluation data using International Prostate Symptom Score (IPSS), quality of life (QoL) score, prostate-specific antigen (PSA), peak urinary flow rate (Qmax), postvoid residual volume (PVR), and prostate volume (PV) at baseline and 3 and 12 months after PAE were obtained. RESULTS Bilateral PAE was performed in all patients. One patient had early clinical failure (3.3%) and another presented with lower urinary tract symptoms (LUTSs) recurrence (3.3%) at the 12-month follow-up. Twenty-eight patients (93.3%) experienced significant and durable LUTS improvement. Mean absolute (and relative) improvement at 3 and 12 months were: IPSS, 14.6 points (-69%) for both; QoL, 3.3 points (-70%) and 3.5 points (-74%); Qmax, 6.3 mL/s (+78%) and 8.6 mL/s (+100%); PSA reduction, 1.2 ng/mL (-22%) and 1.0 ng/mL (-15%); PVR reduction, 48 mL (-56%) and 58.2 mL (-49%); PV reduction, 23.4 cm3 (-29%) and 19.6cm3 (-25%); (P < .05 for all). No major adverse events were observed. Minor adverse events included urinary tract infection (4/30, 13.3%), prostatic tissue elimination (3/30, 10%), penile punctiform ulcer (1/30, 3.3%), and urinary retention (1/30, 3.3%). CONCLUSIONS PAE using PEG microspheres was observed to be effective with sustained LUTS improvement at the 12-month follow-up. The incidence of urinary infection and prostatic tissue elimination was higher than previously reported for other embolics.

Abstract
Transrectal ultrasound (TRUS) is a common modality used during urological procedures that require real-time visualization of the prostate, such as prostate biopsy and peri-prostatic nerve blocks (PNB) for surgical procedures. Current practice for TRUS-guided PNB requires use of costly, fixed, and non-portable ultrasound machinery that can often limit workflow. The Clarius endocavity EC7 probe, a digital, handheld and pocket-sized endocavity ultrasound (US) device, is an alternative, portable technology which was recently shown to accurately visualize and measure prostate dimensions and volume. Moreover, in recent years, there has been a renaissance of office-based treatments for minimally invasive surgical therapies (MIST) for the treatment of benign prostate hyperplasia (BPH). More specifically, the Rezūm procedure has been demonstrated to offer men a short, outpatient therapy with excellent 5-year outcomes in durability and preservation of antegrade ejaculation. While other anesthetic techniques have been described for Rezūm, including inhaled methoxyflurane (Penthrox), nitrous oxide, IV sedation and general anesthesia (which often mandate the presence of an anesthesiology team), US-guided local blocks offer the urologist an independent method for pain management. While most urologists may not have direct access to expensive, cart-based ultrasound systems, point of care ultrasound (POCUS) technology, such as Clarius (Vancouver, BC, Canada) and Butterfly (Butterfly Network, Inc, Guilford, CT, USA), can provide high-resolution imaging in combination with smart phone technology. Herein, we sought to describe the technique for using Clarius EC7 for TRUS-guided PNB and its use in urological application with the Rezūm BPH procedure.

Abstract
BACKGROUND Primary urothelial carcinoma in the prostate (UCP) is extremely rare and occurs most frequently in the bladder. There are only dozens of primary cases reported in the literature. Here, we describe a rare case of primary UCP and review the literature. CASE PRESENTATION A 67-year-old widowed male, was referred to our hospital due to the frequency, and urgency of dysuria. Magnetic resonance imaging (MRI) examination revealed prostate size was about 57 mm × 50 mm × 54 mm, increased prostatic transitional zone, and surrounding of prostatic duct indicate bar isointense T1, short T2, hyperintense DWI, and hyposignal ADC (PI-RADS 3); posterior of peripheral zone indicate patchy isointense T1, short T2, hyperintense DWI, and hyposignal ADC (PI-RADS 5). Subsequently, the patient underwent a transrectal prostate biopsy. Histopathological and immunohistochemical (IHC) assessments showed prostatic high-grade urothelial carcinoma with benign prostatic hyperplasia. Finally, the patient underwent laparoscopic radical prostatectomy. Four months after surgery, CT plain and enhanced scan revealed thickening of the bladder wall. On further workup, cystoscopy revealed lymphoid follicular changes in the cut edge of the radical prostatectomy, and cystoscopic biopsies showed the malignant tumor. CONCLUSIONS Prostatic urothelial carcinoma should always be considered if the patient with severe lower urinary tract symptoms or hematuria, PSA, and digital rectal examination without abnormalities, without a personal history of urothelial cancer, but contrast-enhanced MRI showed the lesion located in the prostate. As of right now, radical surgical resections remain the most effective treatment. The effectiveness of neoadjuvant or adjuvant chemotherapy is still controversial.

Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH) can lead to the detrusor hypertrophy and deterioration of the bladder function with a decrease in its contractile activity. A number of publications are presented in the literature, the results of which indicate the possibility of reducing bladder hypertrophy with alpha-blockers. AIM To carry out the retrospective analysis to study the effect of Alfuprost MR on urodynamic parameters, as well as the influence of the therapy on detrusor thickness and bladder mass in patients with detrusor hypertrophy and bladder outlet obstruction caused by BPH. MATERIALS AND METHODS Outpatient records of 30 patients with lower urinary tract symptoms (LUTS) caused by BPH who received Alfuprost MR as monotherapy for 24 weeks were reviewed. Based on the diaries, the following parameters were assessed: total IPSS score, IPSS voiding (questions No. 1, 3, 5 and 6) and storage subscale scores (questions No. 2, 4 and 7), maximum flow rate (Qmax) according to uroflowmetry, the volume of the prostate and the postvoid residual (assessed by ultrasound), satisfaction with treatment on the quality-of-life score (QoL), as well as the changes in detrusor thickness and bladder mass index. RESULTS An improvement in LUTS severity, starting from the 4th week of treatment, followed by a positive trend that persists until the 24th week of therapy with Alfuprost MR, was found. The overall average IPSS score improved by 39.0% by the 24th week of therapy. At the same time, voiding symptoms improved by 46.8%, and storage symptoms improved by 30.9% by 24 weeks of therapy. The average Qmax increased significantly (p<0.05) by 22.1% after 24 weeks of therapy. The average detrusor thickness decreased by 40,2%. Bladder mass index decreased significantly by an average of 34,3% (p<0.05). QoL score improved significantly (p<0.05) by 2.2 points after 24 weeks of therapy. CONCLUSION During the 24-week treatment of patients with BPH, Alfuprost MR demonstrated clinical efficacy not only in reducing voiding symptoms and in improving the QoL, but also a positive effect on detrusor hypertrophy, as evidenced by changes in detrusor thickness and bladder mass index. The absence of any adverse events, including decrease in blood pressure and heart rate, allows us to recommend Alfuprost MR as an effective treatment for LUTS associated with BPH, which reduces detrusor hypertrophy and has a high safety profile and minimal vasodilating effects.

Abstract
The present study investigated ultrasound (US) phenotypes reflecting prostate cancer (PCa)-related genetic mutations. Herein, integration of radiotranscriptomic data, US and contrast-enhanced ultrasound (CEUS) radiomic images, and RNA sequencing was performed with the aim of significantly improving the accuracy of PCa prognosis. We performed radiotranscriptomic analysis of clinical, imaging, and two genomic (mRNA and microRNA expression) datasets from 48 and 22 men with PCa and benign prostatic hyperplasia (BPH), respectively. Twenty-three US texture features and four microvascular perfusion features were associated with various patterns of 52 differentially expressed genes related to PCa (p < 0.05); 17 overexpressed genes were associated with two key texture features. Twelve overexpressed genes were identified using microvascular perfusion features. Furthermore, mRNA and miRNA biomarkers could be used to distinguish between PCa and BPH. Compared with RNA sequencing, B-mode and CEUS features reflected genomic alterations associated with hormone receptor status, angiogenesis, and prognosis in patients with PCa. These findings indicate the potential of US to assess biomarker levels in patients with PCa.

Abstract
INTRODUCTION The purpose of this article was to evaluate the diagnostic value of prostate health index (PHI) and its derivatives in prostate cancer (PCa) with prostate imaging reporting and data system (PI-RADS)-3 lesions. METHODS Patients with benign prostatic hyperplasia (BPH) (n = 155) were included in the BPH group, while all patients with PCa (n = 49) were enrolled in the PCa group. Between the groups, the serum concentrations of total prostate-specific antigen (TPSA), percent-free prostate-specific antigen (%fPSA), prostate health index (PHI), prostate health index density (PHID), and prostate-specific antigen density (PSAD) were compared. RESULTS On average, 49 (24%) of 204 men had PCa on biopsy, with 81.63% of those cases being clinically serious. Age, prostate volume, TPSA, and PSAD did not significantly differ between the PCa group and the BPH group. In contrast, [-2]pro prostate-specific antigen (p2PSA) (17.10 ± 4.77 vs. 13.93 ± 3.22, p < 0.001), PHI (33.88 ± 8.81 vs. 25.83 ± 5.63, p < 0.001), and PHID (0.52 ± 0.15 vs. 0.38 ± 0.11, p < 0.001) showed a statistically significant difference between the two groups. Compared to conventional PSA, PHI (AUC = 0.786, 95% CI: 0.705-0.867) and PHID (AUC = 0.763, 95% CI: 0.684-0.843) were considerably better predictors of all PCa. The TPSA, %fPSA, p2PSA, PHI, PHID, and PSAD areas under the receiver operating characteristic for clinically significant PCa (csPCa) were 0.587, 0.650, 0.696, 0.823, 0.796, and 0.614, respectively. Out of all the various parameters, PHI and PHID performed very well in this cohort's biopsy outcome prediction. CONCLUSION PHI offers the best diagnostic value for detecting PCa in cases of PI-RADS-3 lesions. Additionally, PHID raised the possibility of csPCa PI-RADS-3 lesions. However, more investigation is required to confirm our results by using multicenter collaboration.

Abstract
OBJECTIVE Prostate cancer diagnosis and treatment are increasing in current public healthcare programs. An improved resolution multiparametric magnetic resonance imaging (MRI) has shown the potential to enhance the detection and differentiation of this medical condition. In this study, MR perfusion parameters were investigated in different ages and diseases to differentiate clinically significant prostate cancer. PATIENTS AND METHODS From January 2017 to December 2022, 72 consecutive patients, who had undergone multiparametric MR imaging were enrolled in this study. Four different patient groups were formed: (1) those with prostate cancer, (2) those with prostatitis, (3) those with benign prostate hyperplasia (BPH), and (4) a control group. Quantitative dynamic contrast-enhanced (DCE)-MRI pharmacokinetic parameters included Ktrans, Kep, Ve, and iAUG. Different measurements were obtained from both the peripheral and transitional zones (PZ and TZ, respectively). Means values were compared between groups based on a univariate analysis. RESULTS Ktrans and Kep values in the PZ were found to be statistically significantly lower in the control group (p = 0. 003 and p = 0. 011, respectively). It was seen that Ktrans and Ve measurements obtained from PZ had a statistically significant determinant in detecting malignancy (p = 0. 013 and p = 0. 036, respectively). It was seen that Ktrans, Ve, and iAUG obtained from the TZ showed a statistically significant difference in prostate cancer (p = 0.025, p = 0.005, and p = 0. 011, respectively) in contrast to other cases. Peripheral Ve values were statistically significantly lower than those measured Ve values from the TZ in prostate cancer cases (p = 0.002) in contrast to the other cases. CONCLUSIONS Quantitative DCE-MRI parameters may vary according to age, disease, and zonal anatomy. These differences may contribute to the diagnosis of clinically relevant prostate cancer.

Abstract
The role of the prostatic middle lobe in the presentation and management of benign prostatic hyperplasia (BPH) is under-appreciated. Middle lobe enlargement is associated with intravesical prostatic protrusion (IPP), which causes a unique type of bladder outlet obstruction (BOO) via a 'ball-valve' mechanism. IPP is a reliable predictor of BOO and the strongest independent factor for failure of medical therapy necessitating conversion to surgical intervention. Men with middle lobe enlargement tend to exhibit mixed symptoms of both the storage and the voiding types, but symptomatology will vary depending on the degree of IPP present. Initial assessments such as uroflowmetry and post-void residual volumes are inadequate to detect IPP and could confound the clinical picture. Radiological evaluation of prostate morphology is key to assessment as it provides important prognostic information and can help with operative planning. Treatment strategies employed for BPH should consider the shape and morphology of prostate adenomata, specifically the presence of middle lobe enlargement and the degree of associated IPP.

Abstract
This study is aimed to explore the performance of texture-based machine learning and image-based deep-learning for enhancing detection of Transitional-zone prostate cancer (TZPCa) in the background of benign prostatic hyperplasia (BPH), using a one-to-one correlation between prostatectomy-based pathologically proven lesion and MRI. Seventy patients confirmed as TZPCa and twenty-nine patients confirmed as BPH without TZPCa by radical prostatectomy. For texture analysis, a radiologist drew the region of interest (ROI) for the pathologically correlated TZPCa and the surrounding BPH on T2WI. Significant features were selected using Least Absolute Shrinkage and Selection Operator (LASSO), trained by 3 types of machine learning algorithms (logistic regression [LR], support vector machine [SVM], and random forest [RF]) and validated by the leave-one-out method. For image-based machine learning, both TZPCa and BPH without TZPCa images were trained using convolutional neural network (CNN) and underwent 10-fold cross validation. Sensitivity, specificity, positive and negative predictive values were presented for each method. The diagnostic performances presented and compared using an ROC curve and AUC value. All the 3 Texture-based machine learning algorithms showed similar AUC (0.854-0.861)among them with generally high specificity (0.710-0.775). The Image-based deep learning showed high sensitivity (0.946) with good AUC (0.802) and moderate specificity (0.643). Texture -based machine learning can be expected to serve as a support tool for diagnosis of human-suspected TZ lesions with high AUC values. Image-based deep learning could serve as a screening tool for detecting suspicious TZ lesions in the context of clinically suspected TZPCa, on the basis of the high sensitivity.

Abstract
Background Pressure flow urodynamic study remains the gold standard for the diagnosis of bladder outlet obstruction; however, their use is limited by their relative unavailability in our environment, cost, and invasiveness. Measurement of bladder wall thickness (BWT) by transabdominal ultrasonography is a promising tool that can be used to diagnose bladder outlet obstruction in our environment where pressure-flow urodynamic study is not readily available. Objective The study aimed to correlate BWT with uroflowmetry and to establish a BWT cut-off in patients with lower urinary tract symptoms (LUTS) due to benign prostatic enlargement. Materials and Methods This was a prospective one-year study of patients with LUTS due to benign prostatic enlargement. The patients were divided into obstructed and non-obstructed groups with Q- max of 10 ml/s serving as the cut-off value. Receiver Operator Curve (ROC) was used to evaluate the performance of BWT in diagnosing BOO. Statistical significance was set at P < 0.05. Results The mean BWT and Q-max were 4.53 ± 2.70 mm and 15.06 ± 9.43 ml/s. There was a negative correlation between BWT and Q-max (r = -0.452, P = 0.000), Q-average (r = -0.336, P = 0.000), and voided volume (r = -0.228, P = 0.046). A BWT cut-off of 5.85 mm was found to be the best threshold to differentiate obstructed from non-obstructed patients with a sensitivity and specificity of 70 and 88.2 percent respectively. Conclusion Bladder wall thickness showed an inverse relationship with maximum flow rate with high sensitivity and specificity. This non-invasive test can be used as a screening tool for BOO in our setting, where the pressure flow urodynamic study is not readily available.

Abstract
BACKGROUND There are many ways to treat prostatic hyperplasia; these are currently more inclined to minimally invasive treatment. We mainly compared the differences between two treatment methods, ultrasound-guided transperineal laser ablation (US-TPLA) and prostatic artery embolization (PAE). PURPOSE To evaluate the efficacy and safety of US-TPLA and PAE in the treatment of benign prostatic hyperplasia (BPH). MATERIAL AND METHODS The clinical information for 40 patients with BPH admitted to our hospital between June 2018 and January 2021 were retrospectively analyzed. The changes in International Prostate Symptom Score (IPSS), quality of life (QoL), maximum urinary flow rate (Qmax), postvoid residual (PVR), prostate volume (PV), and the incidence of complications were compared between groups. RESULTS The IPSS (P < 0.001; P < 0.001), QoL (P < 0.001; P < 0.001), Qmax (P < 0.001; P < 0.001), PVR (P < 0.001; P < 0.001), and PV (P < 0.001; P < 0.001) at three and six months after US-TPLA and PAE improved with respect to those before surgery. There was no significant difference in IPSS (P = 0.235; P = 0.151), QoL (P = 0.527; P = 0.294), Qmax (P = 0.776; P = 0.420), PVR (P = 0.745; P = 0.607), and PV (P = 0.527; P = 0.573) between the groups at three and six months after surgery. No serious complications occurred in either group. CONCLUSION US-TPLA and PAE seem to have a similar short-term efficacy. The efficacy of the two procedures is comparable, and neither is associated with serious complications. US-TPLA and PAE are both effective complementary measures for the treatment of BPH.

Abstract
Dynamic contrast-enhanced MRI (DCE-MRI) is routinely included in the prostate MRI protocol for a long time; its role has been questioned. It provides rich spatial and temporal information. However, the contained information cannot be fully extracted in radiologists' visual evaluation. More sophisticated computer algorithms are needed to extract the higher-order information. The purpose of this study was to apply a new deep learning algorithm, the bi-directional convolutional long short-term memory (CLSTM) network, and the radiomics analysis for differential diagnosis of PCa and benign prostatic hyperplasia (BPH). To systematically investigate the optimal amount of peritumoral tissue for improving diagnosis, a total of 9 ROIs were delineated by using 3 different methods. The results showed that bi-directional CLSTM with ± 20% region growing peritumoral ROI achieved the mean AUC of 0.89, better than the mean AUC of 0.84 by using the tumor alone without any peritumoral tissue (p = 0.25, not significant). For all 9 ROIs, deep learning had higher AUC than radiomics, but only reaching the significant difference for ± 20% region growing peritumoral ROI (0.89 vs. 0.79, p = 0.04). In conclusion, the kinetic information extracted from DCE-MRI using bi-directional CLSTM may provide helpful supplementary information for diagnosis of PCa.

Abstract
PURPOSE To explore whether coil embolization of penile collateral arteries to prevent nontarget embolization during prostatic artery embolization (PAE) negatively affects erectile function. MATERIALS AND METHODS Retrospective analysis was performed on a prospectively maintained multicenter PAE database on all patients with benign prostatic hyperplasia (January 2014 to July 2016). International Index of Erectile Function (IIEF-5) scores were collected at baseline and within 12 months after the procedure. A logistic regression and nearest neighbor propensity-matched analysis (matched for age, baseline IIEF-5 scores, and use of 5α-reductase inhibitors) and paired t test were used to evaluate for differential impact on IIEF-5 scores between the group of patients who underwent (unilateral) penile collateral coil embolization and a matched control group of patients who did not. RESULTS Of a total of 216 patients, 26 underwent coil protection of an accessory pudendal vessel/penile collateral. After exclusions, 22 propensity-matched pairs were identified. The mean IIEF-5 score at baseline for the coil-embolized group was 14.8 ± 8.3 (out of a possible score of 30) and that for the matched control group was 14.0 ± 7.8. At the 12-month follow-up after the procedure, the mean follow-up IIEF-5 score was 15.5 ± 8.0 for the coil-embolized group and 14.2 ± 8.2 for the matched control group. The change in IIEF-5 scores after PAE was not significantly different between the 2 groups (0.66 ± 3.8 vs 0.20 ± 2.0; P = .64; 95% CI, -1.53 to 2.44). CONCLUSIONS When penile collateral arteries were identified, protective coil embolization of penile collateral/accessory pudendal vessels during PAE was unlikely to affect erectile function negatively.

Abstract
BACKGROUND The etiology of lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH) remains uncertain. OBJECTIVE The purpose of our study was to quantitatively analyze anatomic characteristics on magnetic resonance imaging (MRI) to assess novel independent factors for symptoms. METHODS This retrospective single-institution study evaluated treatment-naïve men who underwent prostate MRI within 3 months of international prostate symptom score (IPSS) scoring from June 2021 to February 2022. Factors measured on MRI included: size of the detrusor muscular ring (DMR) surrounding the bladder outlet, central gland (CG) mean apparent diffusion coefficient (ADC), levator hiatus (LH) volume, intrapelvic volume, intravesicular prostate protrusion (IPP) volume, CG volume, peripheral zone (PZ) volume, prostate urethra angle (PUA), and PZ background ordinal score. Multivariable logistic regression and receiver operating characteristic analysis were used to analyze factors for moderate/severe (IPSS ≥ 8) and severe LUTS/BPH (IPSS ≥ 20). RESULTS A total of 303 men (mean age: 66.1 [SD: 8.1]) were included: 154 demonstrated moderate or severe symptoms with 28 severe and 149 with asymptomatic/mild symptoms. Increasing age [p = 0.02; odds ratio (OR): 1.05 (1.01-1.08)], PUA [p = 0.02; OR: 1.05 (1.01-1.09)], LH volume [p = 0.04; OR: 1.02 (1.00-1.05)], and DMR size measured as diameter [p < 0.001; OR: 5.0 (3.01-8.38)] or area [p < 0.001; OR: 1.92 (1.47-2.49)] were significantly independently associated with moderate/severe symptoms, with BMI [p = 0.02; OR: 0.93 (0.88-0.99)] inversely related. For every one cm increase in DMR diameter, patients had approximately five times the odds for moderate/severe symptoms. Increasing DMR size [diameter p < 0.001; OR: 2.74 (1.76-4.27) or area p < 0.001; OR: 1.37 (1.18-1.58)] was independently associated with severe symptoms. Optimal criterion cutoff of DMR diameter for moderate/severe symptoms was 1.2 cm [sensitivity: 77.3; specificity: 71.8; AUC: 0.80 (0.75-0.84)]. Inter-reader reliability was excellent for DMR diameter [ICC = 0.92 (0.90-0.94)]. CONCLUSION Expansion of the DMR surrounding the bladder outlet is a novel anatomic factor independently associated with moderate and severe LUTS/BPH, taking into account prostate volumes, including quantified IPP volume, which were unrelated. Detrusor ring diameter, easily and reliably measured on routine prostate MRI, may relate to detrusor dysfunction from chronic stretching of this histologically distinct smooth muscle around the bladder neck.

Abstract
PURPOSE This review was undertaken to compare the clinical outcomes of prostatic artery embolization (PAE) in patients with >80 versus <80 mL prostatic volume (PV) at the 24-month follow-up to determine whether PV predicted the effectiveness or durability of PAE. MATERIALS AND METHODS The PubMed/MEDLINE database was searched for articles published between 2010 and 2022 using the search term "(prostat∗ artery embolization) AND (long term OR follow-up OR 24-month)." Articles were included if they discussed PAE for benign prostatic hyperplasia (BPH) and reported a minimum follow-up of 24 months. Articles with <10 patients were excluded. A subgroup analysis was performed to evaluate for any difference in clinical outcomes at the 24-month post-PAE follow-up between studies with a mean PV of >80 mL and those with a mean PV of <80 mL. RESULTS A total of 14 studies with 2,260 patients were included, all of which demonstrated significant reduction in symptoms at the 24-month follow-up after PAE. Four studies were included as part of the >80-mL PV subgroup (n = 467), and 10 studies were included as part of the <80-mL PV subgroup (n = 1,793). There was a statistically significant difference between the mean preprocedural PV (128.5 vs 64.0 mL; P = .015). At the 24-month follow-up, there were no significant differences between groups across any of the compared parameters. The collective incidence of major adverse events reported in the studies within this review was <1%. CONCLUSIONS PAE is both safe and durable for patients suffering from BPH and can be effective across a wide range of baseline PVs.

Abstract
BACKGROUND There is an overlap comparing transition zone prostate cancer (TZ PCa) and benign prostatic hyperplasia (BPH) on T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI), creating additional challenges for assessment of TZ tumors on MRI. PURPOSE To evaluate whether amide proton transfer-weighted (APTw) imaging provides new diagnostic ideas for TZ PCa. STUDY TYPE Prospective. POPULATION A total of 51 TZ PCa patients (age, 49-89), 44 stromal BPH (age, 57-92), and 45 glandular BPH patients (age, 56-92). FIELD STRENGTH/SEQUENCE A 3 T; T2WI turbo spin echo (TSE), quantitative T2*-weighted imaging, DWI echo planar imaging, 3D APTw TSE. ASSESSMENT Differences in APTw, apparent diffusion coefficient (ADC), and T2* among three lesions were compared by one-way analysis of variance (ANOVA). Regions of interest were drawn by two radiologists (X.Q.Z. and X.Y.Q., with 21 and 15 years of experience, respectively). STATISTICAL TESTS Multivariable logistic regression analyses; ANOVA with post hoc testing; receiver operator characteristic curve analysis; Delong test. Significance level: P < 0.05. RESULTS APTw among TZ PCa, stromal BPH, and glandular BPH (3.48% ± 0.83% vs. 2.76% ± 0.49% vs. 2.72% ± 0.45%, respectively) were significantly different except between stromal BPH and glandular BPH (P > 0.99). Significant differences were found in ADC (TZ PCa 0.76 ± 0.16 × 10-3 mm2 /sec vs. stromal BPH 0.91 ± 0.14 × 10-3 mm2 /sec vs. glandular BPH 1.08 ± 0.18 × 10-3 mm2 /sec) among three lesions. APTw (OR = 12.18, 11.80, respectively) and 1/ADC (OR = 703.87, 181.11, respectively) were independent predictors of TZ PCa from BPH and stromal BPH. The combination of APTw and ADC had better diagnostic performance in the identification of TZ PCa from BPH and stromal BPH. DATA CONCLUSION APTw imaging has the potential to be of added value to ADC in differentiating TZ PCa from BPH and stromal BPH. EVIDENCE LEVEL 2 TECHNICAL EFFICACY: Stage 2.

Abstract
BACKGROUND AND OBJECTIVE Conventional practice includes a limited depiction of urethral pressure and flows based on fragmented gross clinical observations. However, with technological advancements in simulations, computational fluid dynamics (CFD) can provide an alternative approach to predict the bladder pressure with a concordant quantitative flow field in the urethra. Thus, this study aims to comprehensively analyze the urine flow characteristics in various urethra models using simulations. METHODS Three-dimensional urethra models were constructed for seven specific subjects based on clinical radiographs. Simulations with Reynolds averaged Navier-Stokes model were performed to quantitatively investigate the urine flow under various volume flow rate of voided urine. RESULTS Under benign prostatic hyperplasia, the spindle shape of the prostatic urethra (PRU) generates wake flow. The wake flow was also observed in several regions downstream of the PRU, depending on the urethra shape. This wake flow resulted in total pressure loss and urinary tract dysfunction. When comparing pre- and post-operative urethra models, the bladder pressure decreased by 14.98% in P04 and 4.67% in P06. Thus, we identified variability between surgical results of patients. The bladder pressure according to the volume flow rate of voided urine was investigated using simulations and the theoretical consideration based on hydrodynamics. In theoretical consideration, the bladder pressure was expressed as a second-order polynomial for volume flow rate. These results concur with the simulation results. CONCLUSION Numerical simulation can describe the urine flow field in the urethra, providing the possibility to predict the bladder pressure without requiring painful, invasive interventions, such as cystoscopy. Furthermore, effective treatments to improve urination function can be formulated to be patient-specific, by detecting causes and problem regions based on quantitative analysis and predicting post-surgical outcomes.

Abstract
OBJECTIVE To compare the technical efficacy and safety between prostatic artery occlusion (PAO) with ethylene vinyl alcohol copolymer (EVOH) and prostatic artery embolizsation (PAE) with microspheres in a canine model. METHODS 17 adult male beagles underwent PAO (n = 7) with Onyx-18 or PAE (n = 10) with microspheres (300-500 µm). To evaluate the primary outcomes (technical efficacy and safety), MRI evaluations were performed immediately before and 1 week, 2 weeks, and 1 month after procedures to document prostate volume (PV); and all dogs were inspected for procedure-related complications during 1 month follow-up. The secondary outcomes included the prostate ischaemia size detected by MRI and recanalisation of prostatic artery by follow-up angiography. Differences between groups were statistically analysed. RESULTS Both procedures were bilaterally successful in all animals. Compared with PAE, the mean fluoroscopy time (23.80 vs 36.24 min, p = 0.014) and radiation dose (68.19 vs 125.26 mGy, p = 0.003) were significantly less in PAO procedure. The mean percentage of PV change significantly decreased in both groups at 2 weeks (30.71% vs 37.89%) and 1 month (56.41% %vs 55.56%) after PAO and PAE respectively), without significant differences between groups at either time point. No major complications were observed except one animal after PAO with transient haematuria and acute urinary retention. The mean prostate ischaemia induced by PAO was significant greater compared with PAE at 1 week (43.44% vs 18.91%, p=0.001). PAO with EVOH is technically feasible and with comparable efficacy and safety with PAE. There are possible benefits to PAO over PAE. ADVANCES IN KNOWLEDGE A new technical modification of the PAE consisting of the use of liquid embolic agent to occlude the prostatic artery trunk and its branches has been developed in pre-clinical study, showing to be an effective and safe procedure which can induce a significant prostate shrinkage for the management of symptomatic benign prostatic hyperplasia in patients. In addition, the findings have showed a similar therapeutic effect comparable with the conventional PAE using microspheres.

Abstract
OBJECTIVE To explore the diagnostic performance of the nomogram based on the transabdominal ultrasonographic features of prostatic calcification and varicocele (VC) and serological indicators in differentiating PCa with BPH from simple BPH. METHODS This retrospective study included 108 cases of PCa with BPH and 317 cases of simple BPH, all pathologically confirmed after surgery from January 2014 to December 2021. Using t test or χ2/Fisher test, we compared the clinicopathologic data, transabdominal ultrasonographic features of prostatic calcification, VC severity and serological indicators between the two groups of patients. We identified the significant independent factors for differentiating PCa with BPH from simple BPH by multivariate logistic regression analysis and constructed a nomogram for visualizing the differential diagnostic performance. RESULTS There were significant differences in the types and diameters of prostatic calcification, PSA density (PSAD), total PSA (tPSA), VC severity, and serum testosterone level between the two groups (P < 0.05). The types of calcification, PSAD and VC severity were identified as independent factors for differentiating PCa with BPH from simple BPH. Nomogram analysis of the above factors showed a good predicting performance, with an AUC of 0.805, a sensitivity of 83.28% and a specificity of 70.37%. CONCLUSION Transabdominal ultrasonographic features and types of prostatic calcification, PSAD and VC severity are correlated with the development and progression of PCa. Nomogram analysis of the above factors contributes to the differentiation of PCa with BPH from simple BPH.

Abstract
PURPOSE The structural relationship between benign prostate hyperplasia (BPH) and prostate cancer (Pca) is controversial. The purpose of our study was to examine the association between quantitative prostate compositional metrics by magnetic resonance imaging (MRI) and Pca. METHODS We identified 405 patients who underwent prostate MRI and biopsy and/or prostatectomy from January 2019 to January 2021 at our institution. Segmentation volumetric methods were used to assess central gland (CG) and peripheral zone (PZ) volume. PZ mean thickness and mean apparent diffusion coefficient (ADC), marker of underlying histologic components, were measured. Multivariable logistic regression was performed with outcomes of ≥Grade Group (GG) 2 Pca and for multifocal disease. RESULTS On multivariable analysis, higher CG volumes were at lower odds of ≥GG2 disease (n = 227) (OR: 0.97, 95% CI 0.96-0.98, p < 0.0001), taking into account PZ volume (p = 0.18) and thickness (p = 0.70). For every one cc increase in CG volume, there was an approximately 3% decrease in odds of ≥GG2 disease. Similar findings were noted for multifocal disease (n = 180) (OR: 0.97, 95% CI 0.96-0.98, p < 0.0001). Notably, ADC of the normal PZ was not significantly associated with CG volume (p = 0.21) nor a predictor of disease (p = 0.49). CONCLUSIONS Increasing central gland volume, driven by BPH, is associated with lower odds of significant Pca, including multifocal disease, while PZ anatomic and histologic surrogate changes were noncontributory. Findings support BPH impediment of global tumor growth predicted by theoretical mechanobiological model. This potential stabilizing factor should be further studied for risk stratification and in consideration for BPH therapy.

Abstract
CONTEXT Urodynamic study (UDS) provides the most objective assessment of bladder outlet obstruction (BOO) but is impractical to be recommended routinely in outpatient services. Intravesical prostatic protrusion (IPP) had been described to obstruct urinary flow by creating an anatomical ball-valve effect, but there remains a lack of pooled evidence that can objectively correlate with BOO in benign prostatic hyperplasia. OBJECTIVE To update the current evidence on the predictive role of IPP in determining BOO and unsuccessful trial without catheter (TWOC). EVIDENCE ACQUISITION A comprehensive literature search was performed to identify studies that evaluated IPP in diagnosing UDS-determined BOO and TWOC. The search included the PubMed/MEDLINE, EMBASE, and Cochrane Library up to January 2021. An updated systemic review and meta-analysis was performed. EVIDENCE SYNTHESIS A total of 18 studies with 4128 patients were examined. Eleven studies with 1478 patients examined the role of IPP in UDS-determined BOO. The pooled area under the curve (AUC) was 0.83 (95% confidence interval [CI]: 0.79-0.86), and at a cut-off of >10 mm, the sensitivity (Sn) and specificity (Sp) were 0.71 (95% CI: 0.61-0.78) and 0.77 (95% CI: 0.68-0.84), respectively. The probability-modifying plot revealed positive and negative likelihood ratios of 3.34 (95% CI: 2.56-4.36) and 0.35 (95% CI: 0.26-0.45), respectively. Seven studies with 2650 patients examined IPP in predicting unsuccessful TWOC, with a pooled AUC of 0.74 (95% CI: 0.70-0.84), with Sn of 0.51 (95% CI: 0.43-0.60) and Sp of 0.79 (95% CI: 0.73-0.84) at an IPP cut-off of >10 mm. Five studies compared prostate volume (PV) and IPP and revealed a lower AUC of PV at 0.71 (95% CI: 0.67-0.75), which was an inferior parameter in diagnosing BOO (p < 0.001). CONCLUSIONS This systemic review provided evidence that IPP is a reliable clinical parameter that correlates strongly with underlying BOO and unsuccessful TWOC. PATIENT SUMMARY In this review, we comprehensively reviewed all the literature to date on evaluating the clinical utility of intravesical prostatic protrusion (IPP). We have demonstrated that IPP correlates strongly with urodynamic study (UDS)-determined bladder outlet obstruction and failure of trial without catheter (TWOC). Outpatient IPP measurement is a quick, inexpensive, and reproducible clinical parameter that can determine the severity of benign prostatic hyperplasia. The clinical role of IPP in predicting failure of TWOC selects patients who are best treated with aggressive surgical approaches rather than conservative medical therapies. More importantly, IPP can facilitate the discriminatory use of invasive UDS, reserved for patients with a strong suspicion of concomitant detrusor abnormalities.

Abstract
This study aimed to evaluate the diagnostic performance of diffusion kurtosis imaging (DKI) and prostate-specific antigen (PSA) biomarkers in differentiating prostate cancer (PCa) and benign prostatic hyperplasia (BPH).A total of 43 cases of prostate diseases verified by pathology were enrolled in the present study. These cases were assigned to the BPH group (n = 20, 68.85±10.81 years old) and PCa group (n = 23, 74.13 ± 7.37 years old). All patients underwent routine prostate magnetic resonance imaging and DKI examinations, and the mean diffusivity (MD), mean kurtosis (MK), and fractional anisotropy (FA) values were calculated. Three serum indicators (PSA, free PSA [fPSA], and f/t PSA) were collected. We used univariate logistic regression to analyze the above quantitative parameters between the 2 groups, and the independent factors were further incorporated into the multivariate logistic regression model. The area under the receiver operating characteristic curve (AUC) was used to evaluate the diagnostic efficacy of the single indicator and combined model.The difference in PSA, f/t PSA, MK, and FA between PCa and BPH was statistically significant (P < .05). The AUC for the combined model (f/t PSA, MK, and FA) of 0.972 (95% confidence interval [CI]: 0.928, 1.000) was higher than the AUC of 0.902 (95% CI: 0.801, 1.000) for f/t PSA, 0.833 (95% CI: 0.707, 0.958) for MK, and 0.807 (95% CI: 0.679, 0.934) for FA.The MK and FA values for DKI and f/t PSA effectively identify PCa and BPH, compared to the PSA indicators. Combining DKI and PSA derivatives can further improve the diagnosis efficiency and might help in the clinical setting.

Abstract
PURPOSE The aim of this study was to determine the value of transrectal ultrasound in the definitive diagnosis of hypertrophic interureteral cristae and to provide a definitive diagnostic basis for clinical treatment. MATERIALS AND METHODS When the patient's bladder fills moderately, the ultrasound physician uses the transabdominal ultrasound probe to examine the patient's bladder and prostate carefully, focusing on bilateral ureterovesical portals, a cord-like hyperechoic structure visible between the bilateral ureterovesical portals. For further detailed observation, transrectal probe was used to measure the size of Hypertrophic Interureteral Cristae and describe the shape and internal echo. After the examination, the residual urine volume of bladder was measured after one-time urination. RESULTS Hypertrophic interureteral cristae was a trilinear structure with a "high-low-high" echo. All the 33 patients had bladder wall thickening. In 9 cases of overfilling of bladder, there were slightly dilated ureterovesical portals at both ends of hypertrophic interureteral cristae. Thirty cases of benign prostatic hyperplasia, 11 patients who had undergone prostate hyperplasia surgery, 26 cases with different degrees trabecular and reticular hyperplasia of bladder wall, there were 9 cases with bladder diverticulum and 23 cases with mild hydronephrosis. CONCLUSIONS Transrectal ultrasound can confirm the diagnosis of Hypertrophic Interureteral Cristae.

Abstract
OBJECTIVES In the United States, prostate cancer (PCa) is the most common cancer in men. Multi-parametric magnetic resonance imaging (MRI) is increasingly being relied upon for the diagnosis and characterization of PCa, but differentiating malignancy from benign prostatic hyperplasia (BPH) in the transition zone using MRI can be challenging. The characteristically high levels of zinc in human prostate tissue and a close relationship between malignant proliferation and zinc homeostatic dysregulation create opportunities to visualize PCa with novel contrast media. In mouse models, glucose-stimulated zinc secretion (GSZS) can be preferentially observed in healthy prostate tissue compared with malignant tissue; in vivo, these differences can be captured with MRI by using Gdl1, a gadolinium-based zinc-responsive contrast agent. In this study, we examined whether this technology can be applied in a large animal model by imaging older dogs with clinically diagnosed BPH. MATERIALS AND METHODS Four intact male dogs 6 years or older with enlarged prostates were imaged (T1-weighted turbo spin-echo, TE/TR, 12/400 milliseconds and T2-weighted, TE/TR, 112/5000 milliseconds) using a 3 T scanner before and at multiple time points after intravenous injection of 0.05 mmol/kg GdL1 plus either (a) 2 mL/kg of 50% dextrose in 1 session or (b) 2 mL/kg normal saline in another session. The two sessions were one week apart, and their order was randomly determined for each dog. During postprocessing, regions of interest were generated in prostate tissue and in paraspinal muscles to evaluate the contrast-to-noise ratio (CNR). The ratio of CNR at any postinjection time point compared with baseline CNR was defined as r-CNR. After the second imaging session, the dogs were euthanized, and their prostates were harvested for histopathological examination. Baseline and postintervention plasma and urine samples were analyzed for total zinc by inductively coupled plasma mass spectrometry. RESULTS The mean ± SD r-CNR values at 13 minutes postinjection in the dextrose versus saline imaging sessions were 134% ± 10% and 127% ± 7%, respectively (P < 0.01). The histopathologic evaluation of prostate tissues confirmed BPH in all dogs. Interestingly, prostatic intraepithelial neoplasia was detected in 1 animal, and a suspicious mass was found in the same region on T2-weighted scans. The r-CNR of the mass was calculated as 113% ± 4% and 111% ± 6% in the dextrose and saline groups, respectively, with no significant differences between the 2 interventions (P = 0.54), whereas there was a statistically significant difference between the r-CNR of the whole prostate in the dextrose (130% ±11%) and saline (125% ± 9%) interventions (P = 0.03). Inductively coupled plasma mass spectrometry analyses showed a significantly higher urinary zinc in the dextrose versus saline groups, but no differences were found in plasma zinc levels. CONCLUSIONS T1-weighted MRI of the enlarged canine prostate showed higher r-CNR after injection of GdL1 plus dextrose compared with GdL1 plus saline, consistent with GSZS from BPH tissues. One small region of neoplastic tissue was identified in a single dog on the basis of less GSZS from that region by MRI. These findings suggest a new method for the detection of PCa by MRI that could facilitate the differentiation of BPH from PCa in the transition zone.

Abstract
OBJECTIVES Our study aimed to investigate the correlation of prostatic morphological parameters and benign prostatic hyperplasia (BPH) clinical progression in aging Chinese men. METHODS In this retrospective study, a total of 1038 patients were reviewed. Prostatic morphology was measured by transrectal ultrasound (TRUS). Detailed medical history of all candidates was recorded and analyzed after being classified by specific prostatic measurements. Univariate and multivariate logistic regression analyses were used to estimate the correlation between variables. RESULTS The cumulative incidence of BPH clinical progression was 63.68% (661/1038) in the study population. Prostate volume (PV), transitional zone volume (TZV), transitional zone index (TZI), and intravesical prostatic protrusion (IPP) were all positively associated with BPH progression (all p < .001). Patients with a PV > 60 ml, TZV > 15 ml, TZI > 0.5, or IPP > 5 mm had a significantly higher possibility of overall BPH clinical progression (adjusted odds ratio (OR): 2.485, 1.678, 1.886, and 1.924, respectively; 95% confidence interval (CI): 1.559-3.960, 1.131-2.489, 1.379-2.579, and 1.357-2.728, correspondingly). CONCLUSION Prostatic morphological parameters are significantly associated with BPH clinical progression. Patients with larger prostatic morphological parameters are more easily prone to clinical progress. As a result, reasonable managements should be timely considered for those patients before clinical progression occurs.

Abstract
OBJECTIVE To implement an advanced spatial penalty-based reconstruction to constrain the intravoxel incoherent motion (IVIM)-diffusion kurtosis imaging (DKI) model and investigate whether it provides a suitable alternative at 1.5 T to the traditional IVIM-DKI model at 3 T for clinical characterization of prostate cancer (PCa) and benign prostatic hyperplasia (BPH). MATERIALS AND METHODS Thirty-two patients with biopsy-proven PCa were recruited for MRI examination (n = 16 scanned at 1.5 T, n = 16 scanned at 3 T). Diffusion-weighted imaging (DWI) with 13 b values (b = 0 to 2000 s/mm2 up to 3 averages, 1.5 T: TR = 5.774 s, TE = 81 ms and 3 T: TR = 4.899 s, TE = 100 ms), T2-weighted, and T1-weighted imaging were used on the 1.5 T and 3 T MRI scanner, respectively. The IVIM-DKI signal was modeled using the traditional IVIM-DKI model and a novel model in which the total variation (TV) penalty function was combined with the traditional model to optimize non-physiological variations. Paired and unpaired t-tests were used to compare intra-scanner and scanner group differences in IVIM-DKI parameters obtained using the novel and the traditional models. Analysis of variance with post hoc test and receiver operating characteristic (ROC) curve analysis were used to assess the ability of parameters obtained using the novel model (at 1.5 T) and the traditional model (at 3 T) to characterize prostate lesions. RESULTS IVIM-DKI modeled using novel model with TV spatial penalty function at 1.5 T, produced parameter maps with 50-78% lower coefficient of variation (CV) than traditional model at 3 T. Novel model estimated higher D with lower D*, f and k values at both field strengths compared to traditional model. For scanner differences, the novel model at 1.5 T estimated lower D* and f values as compared to traditional model at 3 T. At 1.5 T, D and f values were significantly lower with k values significantly higher in tumor than BPH and healthy tissue. D (AUC: 0.98), f (AUC: 0.82), and k (AUC: 0.91) parameters estimated using novel model showed high diagnostic performance in cancer lesion detection at 1.5 T. DISCUSSION In comparison with the IVIM-DKI model at 3 T, IVIM-DKI signal modeled with the TV penalty function at 1.5 T showed lower estimation errors. The proposed novel model can be utilized for improved detection of prostate lesions.
