Objective: To evaluate 1-year surgical and functional results and morbidities of prostatic artery embolization (PAE) vs open prostatectomy (OP). Patients and methods: We undertook 1:1 matched-pair analysis (International Prostate Symptom Score [IPSS], peak flow [PF], postvoid residual [PVR], and prostate volume) of 287 consecutive patients treated for benign prostatic obstruction, including 80 OP and 80 PAE. Inclusion criteria were as follows: lower urinary tract symptoms or benign prostatic obstruction, IPSS ≥12, prostate-specific antigen (PSA) <4 ng/mL, or PSA between 4 and 10 ng/mL but negative prostate biopsy, total prostate volume >80 cm(3), and PF <15 mL/s. Follow-up was performed at 1 month, 6 months, and 1 year at clinic. Primary end points of the study were the comparison regarding IPSS, International Index of Erectile Function-5, PF, PVR, and IPSS quality of life (IPSS-QoL) after 1 year of follow-up. Results: Regarding primary end points, OP group had lower IPSS (4.31 vs 10.40; P <.05), 1-year PVR (6.15 vs 18.38; P <.05), 1-year PSA (1.33 vs 2.12; P <.05), IPSS-QoL (0.73 vs 2.78; P <.05), International Index of Erectile Function-5 (10.88 vs 15.13; P <.05), and greater PF (23.82 vs 16.89; P <.01). The matched-pair comparison showed higher value of postoperative hemoglobin level (mg/dL) and shorter hospitalization (days) and catheterization (days) for PAE group. At the multivariate logistic regression, PAE was associated with persistent symptoms (IPSS ≥8; odds ratio, 2.67; 95% confidence interval [CI], 0.96-7.4; P <.01) and persistent PF ≤15 mL/s (odds ratio, 4.95; 95% confidence interval, 1.73-14.15; P <.05) after 1 year. Conclusion: PAE could be considered a feasible minimally invasive technique but failed to demonstrate superiority to OP because of the increased risk of persistent symptoms and low PF after 1 year.

Abstract
Objective: To evaluate 1-year surgical and functional results and morbidities of prostatic artery embolization (PAE) vs open prostatectomy (OP). Patients and methods: We undertook 1:1 matched-pair analysis (International Prostate Symptom Score [IPSS], peak flow [PF], postvoid residual [PVR], and prostate volume) of 287 consecutive patients treated for benign prostatic obstruction, including 80 OP and 80 PAE. Inclusion criteria were as follows: lower urinary tract symptoms or benign prostatic obstruction, IPSS ≥12, prostate-specific antigen (PSA) <4 ng/mL, or PSA between 4 and 10 ng/mL but negative prostate biopsy, total prostate volume >80 cm(3), and PF <15 mL/s. Follow-up was performed at 1 month, 6 months, and 1 year at clinic. Primary end points of the study were the comparison regarding IPSS, International Index of Erectile Function-5, PF, PVR, and IPSS quality of life (IPSS-QoL) after 1 year of follow-up. Results: Regarding primary end points, OP group had lower IPSS (4.31 vs 10.40; P <.05), 1-year PVR (6.15 vs 18.38; P <.05), 1-year PSA (1.33 vs 2.12; P <.05), IPSS-QoL (0.73 vs 2.78; P <.05), International Index of Erectile Function-5 (10.88 vs 15.13; P <.05), and greater PF (23.82 vs 16.89; P <.01). The matched-pair comparison showed higher value of postoperative hemoglobin level (mg/dL) and shorter hospitalization (days) and catheterization (days) for PAE group. At the multivariate logistic regression, PAE was associated with persistent symptoms (IPSS ≥8; odds ratio, 2.67; 95% confidence interval [CI], 0.96-7.4; P <.01) and persistent PF ≤15 mL/s (odds ratio, 4.95; 95% confidence interval, 1.73-14.15; P <.05) after 1 year.
