A comparative study of prostatic artery embolization in the treatment of benign prostatic hyperplasia with different prostatic volume

Objective: To compare the efficacy of prostatic artery embolization (PAE) in the treatment of patients with benign prostatic hyperplasia (BPH) with different prostatic volume (PV). Methods: In this single-center, retrospective study, 137 patients, mean age (70±11) years, range 50-89 years, undergoing PAE for BPH between January 2015 and May 2017 in Chinese PLA General Hospital were involved and divided into three groups according to the PV (group A, >80 ml; group B, 40-80 ml; group C, <40 ml). The changes of international prostate symptoms (IPSS) score, quality of life (QoL) score, and maximum urinary flow rate (Q(max)) were compared among the three groups at 1, 6, and 12 months post-PAE. Correlation between the proportion of prostate ischemia at 1 month post-PAE and the proportion of PV reduction at 12 month post-PAE were analyzed, also the correlation between both of them with IPSS and QoL score were analyzed, respectively. Results: Mean baseline prostate volumes were 110 ml in group A (n=62), 67 ml in group B (n=47) and 33 ml in group C (n=28). At 12 months post-PAE, the outcomes of IPSS score and Q(max) in group A were better than those in group B and C (all P<0.05).The proportion of prostate ischemia at 1 month post-PAE and proportion of PV reduction at 12 month post-PAE in group A, B, and C were 61.4%, 49.3%, 38.0%, and 47.3%, 29.3%, 24.6%, respectively. The proportion of prostate ischemia in group A was larger than that in group B and C (P=0.049, 0.004), also the proportion of PV reduction in group A was greater than that in group B and C (P<0.01). The proportion of prostate ischemia at 1 month post-PAE in all three groups were positively correlated with the proportion of PV reduction at 12 month post-PAE (r=0.699, P=0.024; r=0.719, P=0.019; r=0.821, P=0.004), and there were positive correlations between both of them and the improvement of IPSS score at 12 month post-PAE (0.5<r<1.0, all P<0.05), while no correlation with the improvement of QoL score. Conclusions: Patients with BPH with PV larger than 80 ml are more suitable for PAE. The proportion of prostate ischemia and prostate volume reduction after PAE can predict the efficacy of PAE.
