To study the subscore improvement in International Prostate Symptom Scores (IPSS) after prostatic artery embolization (PAE).
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.
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).
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.
研究前列腺动脉栓塞术（PAE）后国际前列腺症状评分（IPSS）各子评分的改善情况。
进行一项单中心回顾性研究，对2013年12月至2019年7月期间连续37例接受PAE的患者（年龄66.0±8.8岁）进行随访，比较PAE前后的评分结果。IPSS分为储尿（IPSS-s）子评分和排尿（IPSS-v）子评分。将1、3、6和12个月随访以及末次随访时IPSS-s和IPSS-v的变化与基线评分进行比较。还分析了IPSS-s和IPSS-v百分比的变化以及IPSS-s与总IPSS比值（IPSS-s/IPSS-t）和IPSS-v与IPSS-t比值（IPSS-v/IPSS-t）的变化。
在由37例患者组成的研究人群中，IPSS-t从基线时的16.5±7.2显著降至末次随访时（4年后）的8.3±5.7（P<.0001）。此外，在1、3、6和12个月随访时，IPSS-v症状的变化大于IPSS-s症状的变化，在6个月时达到统计学显著性，IPSS-v下降72.9%±42.4%，IPSS-s下降50.1%±52.2%（P=.009）。
PAE可成功降低IPSS-s和IPSS-v，其中IPSS-v降低更为显著。两个子评分的改善在长达4年的随访中持续存在。
