To evaluate the medium and long term outcome of prostatic arterial embolization (PAE) to treat lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH).
Two hundred forty patients (age range, 62 – 82 years; mean age, 74.1 y) with BPH and moderate to severe lower urinary tract symptoms after failure of medical treatment underwent PAE between March 2009 and March 2012. Patients were followed between 1 and 4 years after PAE (mean 18 months).International Prostate Symptom Score (IPSS), quality of life improved (QoL), international Index of Erectile Function (IIEF), peak urinary flow (Qmax), prostate-specific antigen (PSA), prostate volume were evaluated every 6 months. Technical success is defined as embolization of at least one prostatic artery. Clinical success is considered when there is a reduction of the IPSS at least 25% of the total score and ≤ 15, a reduction of the QoL at least 1 point of the total or ≤ 3 and no need of medical or any other treatment.
There were 4 technical failures. From the 236 evaluated patients there were 39 (16.5%) short termclinical failure up to 1 year. Therefore there are 197 evaluated at medium term between 1 and 3 years. From this group of patients evaluated at medium term there were 17 clinical failures. The cumulative rate at 3 years was 23.7%. There are 17 patients followed at long term between 3 and 4 years, with 2 clinical failures. The cumulative rate at 4 years is 75.4%.
There was a major complication a small area of bladder wall base ischemia. Surgery was required to treat that ischemia.
PAE is safe procedure with low morbidity as well as good short, medium and long term results.
Prostatic Artery Ambolization can have a future place in urologic guidelines and it is important to report technical and clinical outcomes.
