A prospective study of 11 patients with urinary retention due to BPH was conducted. Patients underwent physical examination, prostate specific antigen (PSA) measurement, transrectal ultrasound, and magnetic resonance imaging. International prostate symptom score (IPSS), quality of life (QoL), and urodynamic testing were used to assess the outcome before and after 1 year. Clinical success was 91 % (10/11 patients) with a mean follow-up of 22.3 months (range, 12-41 months). At the first year follow-up, the mean IPSS score was 2.8 points (p = 0.04), mean QoL was 0.4 points (p = 0.001), mean PSA decreased from 10.1 to 4.3 ng/mL (p = 0.003), maximum urinary flow (Qmax) improved from 4.2 to 10.8 mL/sec (p = 0.009), and detrusor pressure (Pdet) decreased from 85.7 to 51.5 cm H2O (p = 0.007). Before PAE, Bladder Outlet Obstruction Index (BOOI) showed values > 40 in 100 % of patients. After PAE, 30 % of patients were > 40 (obstructed), 40 % were between 20 and 40 (undetermined), and 30 % were < 20 (unobstructed). Patients with a BOOI < 20 had higher PSA values at 1-day after PAE. Clinical and urodynamic parameters improved significantly after PAE in patients with acute urinary retention due to BPH. Total PSA at day 1 after PAE was higher in patients with unobstructed values in pressure flow studies.engrestrictedAccessClinical practiceImagingArterial interventionEmbolization/embolisation/embolotherapyEndovascular treatmentTranscatheter therapyMRI/MRAProstateUrinary tractbladder outlet obstructiontransurethral resectionmassive hematuriafollow-upmanagementhemorrhagesapeturparticleCopyright SPRINGER10.1007/s00270-013-0611-5Cardiac & Cardiovascular SystemsRadiology, Nuclear Medicine & Medical Imaging
