Background/Objectives: Prostatic artery embolization (PAE) has emerged as a minimally invasive alternative for treating lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH), particularly in high-risk surgical candidates. This study aims to evaluate the efficacy, safety, and clinical outcomes of PAE, combining a retrospective case series with a narrative review of the literature. Methods: A single-center retrospective analysis was conducted on 10 patients aged ≥ 70 years with moderate-to-severe LUTS due to BPH who underwent PAE between January 2021 and January 2024. Inclusion criteria included IPSS > 18, Qmax < 12 mL/s, prostate volume > 45 cc, and resistance to medical therapy. Embolization was performed using 300-500 µm tris-acryl gelatin microspheres via the PErFecTED technique. Follow-up included IPSS, Qmax, prostate volume (PV), PSA levels, and complications. A narrative review of 18 studies (n = 1539 patients) was also conducted to contextualize findings. Results: Technical success was achieved in all patients (100%), and clinical success (IPSS reduction ≥ 50%) in 90%. At 12 months, the following significant improvements were observed: mean IPSS decreased from 24 to 12 (p < 0.0001), Qmax increased from 8.7 to 12.6 mL/s (p < 0.0001), PV reduced from 66.4 to 49.4 cc (p < 0.0001), and PSA from 5.0 to 3.4 ng/mL (p < 0.0001). Outcomes remained stable up to 36 months. Two patients developed transient post-procedural fever; no major complications were recorded. Conclusions: PAE is a safe and effective treatment for LUTS related to BPH, offering durable symptom relief and minimal morbidity, particularly in elderly and comorbid patients. While the evidence supports its role as an alternative to TURP, larger prospective trials are necessary to confirm its long-term efficacy and optimize patient selection.
