Rostambeigi N, Crawford D, Golzarian J. Benefits and advances of Cone Beam CT use in prostatic artery embolization: review of the literature and pictorial essay. CVIR Endovasc 2024; 7:46. [PMID: 38744805 PMCID: PMC11093965 DOI: 10.1186/s42155-024-00459-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Accepted: 05/04/2024] [Indexed: 05/16/2024] Open
Abstract
Prostatic artery embolization (PAE) has proven to be an efficacious treatment for urinary symptoms of benign prostatic hyperplasia. PAE is performed in a complex and challenging anatomical field which may pose difficulties from procedural standpoint. Cone beam computed tomography (CBCT) has been proposed as an invaluable tool during the PAE procedure. A review of different techniques and advancements, as well as demonstration of CBCT benefits via a pictorial overview of the salient examples is lacking. The techniques of CBCT are discussed herein and the virtual injection technology as an advancement in CBCT is discussed. To show the merits of CBCT in PAE, a pictorial overview of various clinical scenarios is presented where CBCT can be crucial in decision making. These scenarios are aimed at showing different benefits including identification of the origin of the prostatic artery and avoiding non-target embolization. Other benefits may include ensuring complete embolization of entire prostate gland as angiographic appearance alone can be inconclusive if it mimics a severely thickened bladder wall or ensuring adequate embolization of the median lobe to provide relief from "ball-valve" effect. Further examples include verification of embolization of the entire prostate when rare variants or multiple (> 2) arterial feeders are present.

Abstract
INTRODUCTION Endoscopic surgery is the standard treatment for benign prostatic hyperplasia (BPH) refractory to pharmacological treatments. In order to reduce invasiveness and preserve sexual function, prostatic artery embolization (PAE) has been developed. However, the technical difficulties of carrying out this procedure and the results, which have yet to be confirmed, mean that it is not currently recommended. The seriousness of the complications generated should lead to a reflection on the benefit-risk balance. The objective is to report a case of penile ischemia after embolization of the prostatic arteries. MATERIAL AND METHOD A severe complication following prostatic artery embolization (PAE) is reported with its clinical and paraclinical evaluation before and after the procedure as well as the therapeutic management. RESULTS Penile necrosis following prostatic artery embolization was reported in a 75-year-old patient despite an attempt of deobstruction. Lower urinary tract symptoms worsened postoperatively, associated with glans necrosis and refractory erectile dysfunction. CONCLUSION The place of PAE in the therapeutic arsenal of BPH needs to be confirmed. This innovative technique exposes the patient to potentially severe risks such as penile ischemia, not encountered in conventional endoscopic surgical treatment. PAE should not be included in the therapeutic armamentarium for BPH outside of clinical trials.

Abstract
Objective To assess the safety and efficacy of prostatic arterial embolization (PAE) for elderly patients with lower urinary tract symptoms secondary to large benign prostatic hyperplasia. Methods Twenty-eight patients (>80 years of age) with prostate volume >80 mL were enrolled from October 2016 to October 2019. PAE was performed using microspheres and functional results were evaluated at 1, 3, 6, and 12 months postoperatively. The following data were recorded: International Prostate Symptom Score (IPSS), quality of life (QoL), maximum urine flow rate (Qmax), post-void residual urine volume, prostate volume and total prostate-specific antigen level. Results Selective prostatic arterial catheterization and embolization were achieved in 27 of 28 patients. Follow-up data were available for those 27 patients until 12 months postoperatively. Significant improvements were found at all postoperative time points in terms of the mean IPSS, mean QoL score, mean Qmax, mean post-void residual urine volume, mean total prostate-specific antigen level, and mean prostate volume. The overall complication rate was 46.4%. Conclusions PAE is an efficacious and safe treatment for elderly patients with large prostate volume; it may offer an effective approach for patients who are not candidates for open or endoscopic surgical procedures because of comorbidities.

Abstract
OBJECTIVE The aim of the Male Lower Urinary Tract Symptoms Committee (CTMH) of the French Urology Association was to propose an update of the guidelines for surgical and interventional management of benign prostatic obstruction (BPO). METHODS All available data published on PubMed® between 2018 and 2020 were systematically searched and reviewed. All papers assessing surgical and interventional management of adult patients with benign prostatic obstruction (BPO) were included for analysis. After studies critical analysis, conclusions with level of evidence and French guidelines were elaborated in order to answer the predefined clinical questions. RESULTS/GUIDELINES Offer a trans-uretral incision of the prostate to treat patients with moderate to severe lower urinary tract symptoms (LUTS) with a prostate volume<30cm3, without a middle lobe. TUIP increases the chances of preserving ejaculation. Propose mono- or bipolar trans-urethral resection of the prostate (TURP) to treat patients with moderate to severe LUTS with a prostate volume between 30 and 80cm3. Vaporization by Greenlight™ or by bipolar energy can be offered as an alternative to TURP. Offer a Greenlight™ laser vaporization to patients at risk of bleeding. Offer endoscopic prostate enucleation to surgically treat patients with moderate to severe LUTS as an alternative to TURP and open prostatectomy (OP). Minimally invasive prostatectomy is an alternative to OP in centers without access to adequate endoscopic procedures. Embolization of the prostatic arteries may be offered in the event of a contraindication or refusal of surgery for prostates with a volume>80cm3. Prostatic uretral lift is an alternative in patients interested in preserving their ejaculatory function and with a prostate volume<70cm3 without a middle lobe. Aquablation and Rezum™ are under evaluation and should be offered in research protocols. CONCLUSION Major changes in surgical management of BPO have occurred and aim at reducing morbidity and improving quality of life of patients.

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

Abstract
To evaluate the clinical efficacy and safety of thulium laser vapoenucleation/enucleation of the prostate (ThuEP) versus holmium laser enucleation of the prostate (HoLEP) in the management of benign prostatic hyperplasia (BPH). A systematic literature search was performed using PubMed, Embase, and Web of Science to identify eligible studies published before July 2018. Meta-analysis of extracted data was performed with RevMan version 5.3. We chose the fixed- or random-effect model to fit the pooled heterogeneity. Five eligible studies including two randomized controlled trials (RCTs) and three non-RCTs involving 1010 patients were enrolled in our meta-analysis. ThuEP provided less enucleation time when compared with HoLEP (WMD = - 7.73, 95% CI - 14.39-1.07, P = 0.02). During the 1st, 6th, and 12th months of postoperative follow-ups, statistically significant differences were found in Qmax (WMD = 2.05, 95% CI 0.52~3.58) and PVR (WMD = - 6.50, 95% CI - 7.35~- 5.66, P < 0.001) in the 1st month after the operation, also in IPSS (IPSS: WMD = - 1.29, 95% CI - 2.39~- 0.19, P = 0.02) in the 12th month after the operation. As regards other perioperative, postoperative parameters, and complication rates, we found no significant difference. Both ThuEP and HoLEP provided satisfactory micturition improvement with low morbidity after the 1st and 6th months of the operation. However, ThuEP showed higher enucleation efficacy and less intraoperative blood loss and may get a better outcome as compared to the HoLEP group in the early postoperative period with regard to Qmax/PVR and IPSS after the 1st and 12th months of the operation respectively.

Abstract
Background Prostatic artery embolization (PAE) has been proved effective in the treatment of lower urinary tracts (LUTS) secondary to benign prostatic hyperplasia (BPH) with low complications, and most of the them are due to non-target embolization of adjacent organs, such as bladder, rectum, seminal vesicles and penis. Aim of this study was to present seminal vesicle (SV) abnormalities following prostatic artery embolization (PAE) for the treatment of symptomatic benign prostatic hyperplasia. Methods We reviewed 139 BPH patients who received PAE during the period of February 2009 and January 2015 at a single institution, highlighting seminal vesicle abnormalities and their clinical relevance after PAE. PAE was performed using 90~ 180-μm (mean 100-μm) polyvinyl alcohol foam particles. Results Nine of 139 patients with SV abnormalities (6.5%) were identified by magnetic resonance imaging (MRI), including subacute haemorrhage in 3 patients and ischaemia in 6 patients. Using cone-beam computed tomography (CB-CT), the seminal vesicle arteries were identified 8 of the 9 patients. All 9 patients complained of a few episodes of mild haematospermia during the 1–4 weeks after PAE; the haematospermia disappeared spontaneously without any treatment. Conclusion SV haemorrhage and ischaemia may occur after PAE, and these patients may present with transient and self-limited haematospermia.

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.

Purpose To evaluate the relationship between prostatic vessel changes induced by cigarette smoking and the perioperative outcome of holmium laser enucleation of the prostate (HoLEP). Materials and Methods A total of 268 postoperative patients with benign prostatic hyperplasia (BPH) were prospectively analysed in our department. They were divided into two groups (smokers and non-smokers) according to smoking history. Transrectal colour Doppler ultrasound was performed to evaluate the prostate vascular changes. Pathologically, HE staining, CD31 and CD34 were analysed in prostatic section chips. Furthermore, postoperative outcomes were determined during a 6-month follow-up period. Results The preoperative prostate volume was significantly decreased in smoking patients (P = 0.04). CPI was significantly lower in smoking BPH patients (P < 0.01), whereas RI was significantly increased in smokers compared with non-smokers (P < 0.01). Histological assays revealed elevated CD34 in the smoking BPH individuals presenting an increased number of microvessels. The HoLEP duration was increased in smokers. Interestingly, we identified significantly increased overactive bladder syndrome score (OABSS) and decreased Qmax in smoking individuals during the 6-month follow-up with no difference being observed preoperatively. However, no significant difference between the groups was observed for the International Prostate Symptom Score (IPSS). Conclusions The significantly lower CPI and higher RI values in smoking BPH patients indicated the presence of considerable vascular damage in these subjects. Moreover, cigarette smoking extended the surgical duration and prolonged the recovery period of overactive bladder (OAB) syndrome. Thus, integrated treatment should be suggested for various BPH individuals.

Abstract
PURPOSE To compare the safety and efficacy of PAE for the treatment of benign prostatic hyperplasia (BPH) in men ≥75 years, who we defined as elderly, to those <75 years. METHODS A total of 157 patients diagnosed with lower urinary tract symptoms (LUTS) due to BPH underwent PAE. Group A (n = 52) included patients ≥75 years, and group B (n = 105) included patients <75 years. Follow-up was performed using the International Prostate Symptoms Score (IPSS), quality of life (QoL), peak urinary flow rate (Q max), post-void residual volume (PVR), the International Index of Erectile Function short form (IIEF-5), prostatic-specific antigen (PSA), and prostate volume (PV), at 1, 3, 6, and every 6 months thereafter. RESULTS More coexistent systemic diseases were identified in group A than in group B (P < 0.05). Technical success rate of PAE was 90.4 % in group A and 95.2 % in group B (P = 0.06). A total of 147 patients had completed the follow-up with a mean of 20 months. Compared with the baseline, there were significant improvements in IPSS, QoL, Q max, PV, PVR, and PSA in both groups after PAE. There were no significant differences in the changes of IPSS, Q max, PVR, PSA, and IIEF-5 between groups after PAE. No major complications were noted. CONCLUSION PAE could be used as an effective, safe, and well tolerable method in the treatment of elderly symptomatic BPH patients, similarly to younger patients, and it may play an important role in patients in whom medical therapy has failed, who are at high surgical and anesthetic risk or who refuse the standard surgical therapy.
