Prostatic Artery Embolization for Benign Prostatic Obstruction: Single-Centre Retrospective Study Comparing Microspheres Versus n-Butyl Cyanoacrylate.

PAE using NBCA was safe and effective for symptomatic BPO, with faster procedures, lower radiation exposure and similar safety and efficacy compared to microspheres. Operator learning curve could have biased the procedural times and radiation exposure between groups favouring NBCA.
