  • Description: Analyze the individual baseline parameters to predict the outcome of prostatic artery embolization (PAE) for benign prostatic hyperplasia (BPH). Retrospective study (March 2009 - March 2012). Poor outcome after PAE considered when 1 criteria was met: International Prostate Symptom Score (IPSS) ≥ 20 and/or reduction < 25%; Quality of Life (QoL) ≥ 4 and/or reduction < 1; additional treatments required. PAE performed in 172 patients (mean follow-up 9.6 months; range 3-24 months). Poor outcome (Group A): 53 patients (30.8%, mean follow-up 11.0 months); Good outcome (Group B): 119 patients (69.2%, mean follow-up 9.0 months). In Group A 11.3% (n=6) and in Group B 12.6% (n=15) of patients were under acute urinary retention before PAE (p=0.5). In Group A 37.7% (n=20) and in Group B 28.6% (n=34) of patients were medicated with 5-alpha reductase inhibitors before PAE (p=0.3). Mean baseline parameters (age/prostate volume/PSA/IPSS/QoL/Qmax/Post-void residual volume - PVR) - Group A: 67.3 years / 81.1 mL / 4.9 ng/mL / 23.9 / 4.5 / 9.0 mL/s / 100.0 mL; Group B: 64.7 years / 84.0 mL / 5.9 ng/mL / 23.5 / 4.2 / 9.3 mL/s / 97.6 mL (p>0.05). Unilateral embolization performed in 11 patients from Group A (20.8%) and 14 patients from Group B (11.8%) (p=0.2). PAE performed with 100 μm PVA particles in 45.3% (Group A) and 32.8% (Groups B) of patients; PAE performed with 200 μm PVA particles in 22.6% (Group A) and 32.8% (Groups B) of patients; PAE performed with 100 + 200 μm PVA particles in 18.9% (Group A) and 21.9% (Groups B) of patients; PAE performed with 300-500 μm microspheres in 13.2% (Group A) and 12.6% (Groups B) of patients (p=0.4). In Group A there were 40 (75.5%) non-responders and 13 (24.5%) relapses. Approximately 30% of patients may have poor outcome in the first year after PAE for BPH and most are non-responders. There were no statistically significant differences in the baseline parameters between patients with poor and good clinical outcome. Unilateral embolization and PAE with 100 μm PVA particles were more frequent in patients with poor clinical outcome.
