Purpose: To evaluate the safety and efficacy of repeat prostatic artery (PA) embolization (PAE) for benign prostatic hyperplasia (BPH). Materials and Methods: A single-center retrospective study was conducted from 2009 to 2018 in 108 patients with symptomatic BPH treated with repeat PAE: group A (n = 39; 36.1%) were patients who never showed a response to PAE, and group B (n = 69; 63.9%) were patients who had clinical improvement in the first 6 months following PAE but relapsing symptoms afterward. The main patterns of revascularization were 75% from the previously embolized PA and 25% from collateral vessels (superior vesical, posterior-lateral PA, penile branches). Technical outcomes and adverse events were registered. International Prostate Symptom Score (IPSS), quality of life (QOL), and clinical success were compared between groups. Results: Median follow-up was 18 months (range, 1–36 mo); median interval between PAE and repeat PAE was 420 days (range, 77–2,240 d). Mean procedural time was significantly longer for repeat PAE vs initial PAE (81.1 min vs 67.4 min; P = .0007). There were no major complications and no urinary incontinence. Mean IPSS/QOL improvements were greater in group B vs group A: 9.51 vs 6.13 and 1.30 vs 0.56, respectively (P < .001). The cumulative probability of clinical success after repeat PAE was higher in group B than in group A (P = .0001): 84.1% vs 46.2% at 1 month, 56.7% vs 28.2% at 12 months, and 51.9% vs 16.9% at 24–36 months. Conclusions: Repeat PAE is safe and effective for recurrence of lower urinary tract symptoms caused by BPH but has limited impact in patients who did not show a response to initial PAE.
