    (2019) ASSIS, Andre Moreira de; MOREIRA, Airton Mota; CARNEVALE, Francisco Cesar; MARCELINO, Antonio Sergio Zafred; CERRI, Luciana Mendes de Oliveira; ANTUNES, Alberto Azoubel; SROUGI, Miguel; CERRI, Giovanni Guido
    PurposeTo determine the effects of prostatic artery embolization (PAE) on prostaticelasticity 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 MethodsThis 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.ResultsAfter 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).ConclusionsFindings described in this study suggest that PAE significantly reduces prostaticEM, 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.

    Quality of Life and Clinical Symptom Improvement Support Prostatic Artery Embolization for Patients with Acute Urinary Retention Caused by Benign Prostatic Hyperplasia
    (2013) CARNEVALE, Francisco C.; MOTTA-LEAL-FILHO, Joaquim M. da; ANTUNES, Alberto A.; BARONI, Ronaldo H.; MARCELINO, Antonio S. Z.; CERRI, Luciana M. O.; YOSHINAGA, Eduardo M.; CERRI, Giovanni G.; SROUGI, Miguel
    Purpose: To show that prostatic artery embolization (PAE) improves quality of life (QoL) and lower urinary tract symptoms in patients with acute urinary retention caused by benign prostatic hyperplasia (BPH). Materials and Methods: This was a single-center prospective study of PAE in 11 patients with BPH managed With indwelling. urinary catheters. International Prostate Symptom Score (IPSS), ultrasound, magnetic resonance (MR) imaging, QoL, and urodynamic tests were used. to assess outcomes. Prostate size ranged from 30 to 90 g, and embolizations were performed with 300-500-mu m Embosphere microspheres. Results: The rate of technical success (ie, bilateral PAE) was 75%, and the rate of clinical success (ie, catheter removal and symptom improvement) was 91% (10 of 11 patients). Postembolization syndrome manifested as mild pain in the perineum, retropubic area, and/or urethra. Ten of 11 patients urinated spontaneously after Foley catheter removal 4-25 days after PAE (mean, 12.1 d). No major complications Were observed. Follow-up ranged from 19 to 48 months. than asymptomatic patient, a discrete area of hypoperfusion: suggesting small ischemia of the bladder was observed on 30-day MR imaging follow-up, but the bladder was normal on 90-day MR imaging. After 1 year, mean prostate volume reduction was greater than 30%, symptoms were mild (mean IPSS, 2.8 +/- 2.1; P = .04),. no erectile dysfunction was observed, and QoL,improved significantly (mean , 0.4 +/- 0.5; P = .001) using the paired t test. Conclusions: Patients with severe symptoms and acute urinary retention caused by BPH can be treated Safely by PAE, which improves clinical symptoms and QoL.

    Impact of 5-Alpha-Reductase Inhibitors Use at the Time of Prostatic Artery Embolization for Treatment of Benign Prostatic Obstruction
    (2019) CARDARELLI-LEITE, Leandro; ASSIS, Andre M. de; MOREIRA, Airton M.; ANTUNES, Alberto A.; CERRI, Giovanni G.; SROUGI, Miguel; CARNEVALE, Francisco C.
    Purpose: To compare the 12-month post-prostatic artery embolization (PAE) clinical outcomes of patients who were and were not taking 5-alpha-reductase inhibitors (5ARIs) at the time of PAE. Materials and Methods: A retrospective review was conducted of patients who underwent PAE from 2010 to 2017 due to lower urinary tract symptoms, secondary to benign prostatic hyperplasia (BPH). One hundred fifty-five patients were included and divided in 2 groups; these groups did not present statistically significant differences in their baseline characteristics-those taking 5ARIS (Y-5ARIs, n = 40) and those not taking 5ARIs (N-5ARIs, n = 115). International Prostate Symptom Score (IPSS), the sub-item Quality of Life (QoL), and the incidence of clinical failure were used as primary endpoints. Secondary endpoints included mean prostate volume reduction and mean peak flow rate (Q(max)) improvement. Clinical failure or recurrence was defined as absence of symptomatic improvement (IPSS >= 8 or QoL >= 3) or the need for invasive BPH treatment (PAE or transurethral resection of the prostate) during the 12-month follow-up period. Results: After 12-month follow-up, IPSS, QoL, and prostatic volume were significantly lower compared to baseline in both groups, and Q(max) showed a significant increase. No statistically significant differences were observed in outcomes between N-5ARIs and Y-5ARIs, and the clinical failure rate for both groups was approximately 20%. Conclusions: The use of 5ARIs did not show a detrimental effect on clinical outcomes of PAE, in either subjective (IPSS, QoL, and clinical failure) or objective (prostatic volume and Q(max)) parameters.

    Clinical, Laboratorial, and Urodynamic Findings of Prostatic Artery Embolization for the Treatment of Urinary Retention Related to Benign Prostatic Hyperplasia. A Prospective Single-Center Pilot Study
    (2013) ANTUNES, Alberto A.; CARNEVALE, Francisco C.; LEAL FILHO, Joaquim M. da Motta; YOSHINAGA, Eduardo M.; CERRI, Luciana M. O.; BARONI, Ronaldo H.; MARCELINO, Antonio S. Z.; CERRI, Giovanni G.; SROUGI, Miguel
    This study was designed to describe the clinical, laboratorial, and urodynamic findings of prostatic artery embolization (PAE) in patients with urinary retention due to benign prostatic hyperplasia (BPH). A prospective study of 11 patients with urinary retention due to BPH was conducted. Patients underwent physical examination, prostate specific antigen (PSA) measurement, transrectal ultrasound, and magnetic resonance imaging. International prostate symptom score (IPSS), quality of life (QoL), and urodynamic testing were used to assess the outcome before and after 1 year. Clinical success was 91 % (10/11 patients) with a mean follow-up of 22.3 months (range, 12-41 months). At the first year follow-up, the mean IPSS score was 2.8 points (p = 0.04), mean QoL was 0.4 points (p = 0.001), mean PSA decreased from 10.1 to 4.3 ng/mL (p = 0.003), maximum urinary flow (Qmax) improved from 4.2 to 10.8 mL/sec (p = 0.009), and detrusor pressure (Pdet) decreased from 85.7 to 51.5 cm H2O (p = 0.007). Before PAE, Bladder Outlet Obstruction Index (BOOI) showed values > 40 in 100 % of patients. After PAE, 30 % of patients were > 40 (obstructed), 40 % were between 20 and 40 (undetermined), and 30 % were < 20 (unobstructed). Patients with a BOOI < 20 had higher PSA values at 1-day after PAE. Clinical and urodynamic parameters improved significantly after PAE in patients with acute urinary retention due to BPH. Total PSA at day 1 after PAE was higher in patients with unobstructed values in pressure flow studies.

    Prostatic Artery Embolization: Indications, Preparation, Techniques, Imaging Evaluation, Reporting, and Complications
    (2021) JR, Ubenicio Silveira Dias; MOURA, Mauricio Ruettimann Liberato de; VIANA, Publio Cesar Cavalcante; ASSIS, Andre Moreira de; MARCELINO, Antonio Sergio Zanfred; MOREIRA, Airton Mota; LEITE, Claudia Costa; CERRI, Giovanni Guido; CARNEVALE, Francisco Cesar; HORVAT, Natally
    Benign prostatic hyperplasia (BPH) is a noncancerous growth of the transitional zone of the prostate, which surrounds the prostatic urethra. Consequently, it can cause lower urinary tract symptoms (LUTS) and bladder outlet obstruction symptoms that may substantially reduce a patient's quality of life. Several treatments are available for BPH, including medications such as alpha-blockers and 5 alpha-reductase inhibitors and surgical options including transurethral resection of the prostate and prostatectomy. Recently, prostatic artery embolization (PAE) has emerged as a minimally invasive treatment option for selected men with BPH and moderate to severe LUTS. Adequate pre- and postprocedural evaluations with clinical examinations and questionnaires, laboratory tests, and urodynamic and imaging examinations (particularly US, MRI, and CT) are of key importance to achieve successful treatment. Considering that the use of PAE has been increasing in tertiary hospital facilities, radiologists and interventional radiologists should be aware of the main technical concepts of PAE and the key features to address in imaging reports in pre- and postprocedural settings. An invited commentary by Lopera is available online. Online supplemental material is available for this article. (C) RSNA, 2021

    A Review of Adverse Events Related to Prostatic Artery Embolization for Treatment of Bladder Outlet Obstruction Due to BPH
    (2017) MOREIRA, Airton Mota; ASSIS, Andre Moreira de; CARNEVALE, Francisco Cesar; ANTUNES, Alberto Azoubel; SROUGI, Miguel; CERRI, Giovanni Guido
    Minimally invasive procedures have gained great importance among the treatments for benign prostate hyperplasia (BPH) due to their low morbidity. Prostate artery embolization has emerged as a safe and effective alternative for patients with large volume BPH, not suited for surgery. Low adverse events rates have been reported following prostate artery embolization and may include dysuria, urinary infection, hematuria, hematospermia, acute urinary retention and rectal bleeding. Although most complaints are reported as side effects, complications can also be superimposed. The prostate gland is the most common source of complaints following PAE, where the inflammatory process can create a large variety of localized symptoms. Periprostatic organs and structures such as bladder, rectum, penis, seminal vesicle, pelvis, bones and skin may be damaged by nontarget embolization, especially due to the misidentification of the normal vascular anatomy and variants or due to inadvertent embolic reflux. Radiodermatitis may also happen in case of small vessel size, atherosclerosis, the learning curve and long procedure or fluoroscopy times. Regarding safety, it is pivotal to understand the pathophysiology of adverse events following PAE and their standardized reporting. The aim of this article is to discuss adverse events, their management and to review the current literature.

    Prostatic Artery Embolization for the Treatment of Lower Urinary Tract Symptoms Due to Benign Prostatic Hyperplasia: 10 Years' Experience
    (2020) CARNEVALE, Francisco Cesar; MOREIRA, Airton Mota; ASSIS, Andre Moreira de; ANTUNES, Alberto Azoubel; RODRIGUES, Vanessa Cristina de Paula; SROUGI, Miguel; CERRI, Giovanni Guido
    Background: Long-term experience with prostatic artery embolization (PAE) for benign prostatic hyperplasia remains limited. Purpose: To evaluate the efficacy, safety, and long-term results of PAE for benign prostatic hyperplasia. Materials and Methods: This retrospective single-center study was conducted from June 2008 to June 2018 in patients with moderate-to severe benign prostatic hyperplasia-related symptoms. International Prostate Symptom Score (IPSS), quality-of-life score, maximum urinary flow rate, postvoid residual volume, prostate-specific antigen (PSA), and prostate volume were assessed. PAE was performed with 100-500-mu m embolic microspheres. Mixed-model analysis of variance and Kaplan-Meyer method was accessed, as appropriate. Results: A total of 317 consecutive men (mean age 6 standard deviation, 65 years 6 8) were treated. Follow-up ranged from 3 months to 96 months (mean, 27 months). Bilateral and unilateral PAE was performed in 298 (94%) and 19 (6%) men, respectively. Early clinical failure occurred in six (1.9%) and symptom recurrence in 72 (23%) men at a median follow-up of 72 months. Mean maximum improvement was as follows: IPSS, 16 points +/- 7; quality-of-life score, 4 points +/- 1; prostatic volume reduction, 39 cm(3) +/- 39 (39% +/- 29); maximum urinary flow rate, 6 mL/sec +/- 10 (155% +/- 293); and postvoid residual volume, 70 mL +/- 6121 (48% +/- 81) (P < .05 for all). Unilateral PAE was associated with higher recurrence (42% vs 21%; P =.04). Baseline PSA was inversely related with recurrence (hazard ratio, 0.9 per nanograms per milliliter of PSA; 95% confidence interval [CI], 0.8, 0.9; P < .001). Embolization with combined particle sizes (100-500 mu m) did not relate to symptom recurrence (hazard ratio, 0.4; 95%CI: 0.2, 1.1 for 100-500-mu m group vs 300-500-mu m group and hazard ratio, 0.4; 95% CI: 0.1, 1.5 for 100-500-mu m group vs 100-300-mm group; P =.19). None of the patients presented with urinary incontinence or erectile dysfunction. Conclusion: Prostatic artery embolization was a safe and effective procedure for benign prostatic hyperplasia with good long-term results for lower urinary tract symptoms. (C) RSNA, 2020
