This retrospective study evaluates post-procedural symptom score changes after prostate artery embolization (PAE) with (Coil-out) and without (Standard) adjunctive prostate artery coiling after particle embolization. Changes in IPSS, QOL/Bother, and SHIM-IIEF V are reported at 1-5- and 9-15-month intervals. 573 procedures were reviewed, and 317 patients were included with a mean age of 72.1 years. Results favored the Standard group with greater IPSS reduction at 1-5 (-12.2 vs. -9.9, p = 0.018) and 9-15 months (-12.5 vs. -7.6, p = 0.018), and greater QOL/Bother improvement in the Standard group at 9-15 months (-2.8 vs. -1.8, p = 0.014). Procedure times were longer in the Standard group (186 vs. 173 min; p = 0.039), whereas fluoroscopy times were longer in the Coil-out group (48.3 vs. 44.8 min; p = 0.014). Though limited by retrospective nature and lack of longer-term follow-up, these results support particle embolization alone over adjunctive coil embolization for PAE.
