Resumo
<bold>Purpose: </bold>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).<bold>Materials and methods: </bold>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.<bold>Results: </bold>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%).<bold>Conclusions: </bold>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.
