Abstract
PURPOSE: To study the subscore improvement in International Prostate Symptom Scores (IPSS) after prostatic artery embolization (PAE). MATERIALS AND METHODS: A single-center retrospective study was carried out with follow-up from December 2013 to July 2019 in 37 consecutive patients (66.0 ± 8.8 years old) who underwent PAE, comparing resultant scores before and after PAE. IPSS were divided into storage (IPSS-s) subscores and voiding (IPSS-v) subscores. The changes between IPSS-s and IPSS-v at 1, 3, 6, and 12 months' follow-up as well as the last follow-up were compared with baseline scores. The changes in percentages of IPSS-s and IPSS-v and the changes in average IPSS-s-to-total IPSS ratios (IPSS-s/IPSS-t) and IPSS-v-to-IPSS-t ratios (IPSS-v/IPSS-t) were also analyzed. RESULTS: In the study population, consisting of 37 patients, IPSS-t significantly decreased from 16.5 ± 7.2 at baseline to 8.3 ± 5.7 at the last follow-up (4 years later) (P < .0001). Additionally, the changes in IPSS-v symptoms were greater than the changes in IPSS-s symptoms at 1, 3, 6, and 12 months' follow-up, reaching a statistical significance at 6 months with a decrease of 72.9% ± 42.4% for IPSS-v and a decrease of 50.1% ± 52.2% for IPSS-s (P = .009). CONCLUSIONS: PAE can successfully reduce both IPSS-s and IPSS-v with predominant IPSS-v reduction. The improvements in both subscores were sustained for up to 4 years of follow-up.
