The STREAM Trial (Prostatic Artery Embolization for the Treatment of Benign Prostatic Hyperplasia) 24-Month Clinical and Radiological Outcomes

To establish factors predictive of success prior to Prostate Artery Embolization (PAE) with MRI imaging. A prospective cohort study of 50 patients with Benign Prostatic Hyperplasia (BPH) were treated with PAE in a single institution. Patients had moderate to severe symptoms of BPH refractory to medical management for at least 6 months. Patients were imaged with multiparametric MRI imaging pre-PAE and at 3 months, 12 months and 24 months post-PAE. Clinical success was measured with IPSS, IIEF and EQ-5D-5L quality of life questionnaires. The technical success was 48/50 (96%).The mean age of the group was 67 (range 54–83). The mean IPSS score pre-PAE was 21 and at 24 months was 8 (p
