    Prostatic Artery Embolization Using Polyethylene Glycol Microspheres: A 1-Year Follow-up Prospective Study Including 30 Patients
    (2023) PILAN, Bruna Ferreira; ASSIS, Andre Moreira de; MOREIRA, Airton Mota; RODRIGUES, Vanessa Cristina de Paula; ROCHA, Arthur Diego Dias; CARNEVALE, Francisco Cesar
    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-mu m 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 cm(3) (-29%) and 19.6cm(3) (-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.

    Prostatic artery embolization using reflux-control microcatheter: prospective experience addressing feasibility
    (2022) ASSIS, Andre Moreira de; KAWAKAMI, Willian Yoshinori; MOREIRA, Airton Mota; CARNEVALE, Francisco Cesar
    PurposeTo evaluate the efficacy and safety of Prostatic Artery Embolization (PAE) using a reflux control microcatheter. Materials and methodsThis is a prospective, single-center investigation that included 10 patients undergoing PAE for treatment of lower urinary tract symptoms (LUTS) attributed to benign prostate hyperplasia (BPH). Baseline, 3-month, and 12-month efficacy endpoints were obtained for all patients and included prostate-specific antigen (PSA), uroflowmetry, pelvic magnetic resonance imaging (MRI), and clinical assessment using the International Prostate Symptom Score (IPSS) questionnaire and the IPSS-Quality of life (QoL) item. Complications were assessed using the Cirse classification system. ResultsTen patients entered statistical analysis and presented with significant LUTS improvement 12 months after PAE, as follows: mean IPSS reduction of 86.6% (2.8 vs. 20.7, - 17.9, P < 0.001), mean QoL reduction of 79.4% (1.1 vs. 5.4, - 4.3, P < 0.001), mean prostatic volume reduction of 38.4% (69.3 cm(3) vs. 112.5 cm(3), - 43.2 cm(3), P < 0.001), mean peak urinary flow (Qmax) increase of 199.4% (19.9 mL/s vs. 6.6 mL/s, + 13.3 mL/s, P = 0.006) and mean PSA reduction of 50.1% (3.0 ng/mL vs. 6.1 ng/mL, - 3.0 ng/mL, P < 0.001). One patient (10%) needed transurethral resection of the prostate (TURP) after PAE due to a ball-valve effect. One microcatheter (10%) needed to be replaced during PAE due to occlusion. Non-target embolization was not observed in the cohort. ConclusionThis initial experience suggests that PAE using a reflux control microcatheter is effective and safe for the treatment of LUTS attributed to BPH.
