The application of prostate artery embolization in the management of intractable prostate bleeding

Abstract

Introduction Prostate cancer is one of the most common malignancies affecting European men. Sequelae of the advanced malignancy require invasive procedures which may not be eligible especially for old, debilitated patients. The aim of this manuscript is to review the outcomes of prostate artery embolization in the management of refractory bleeding. Material and methods A PubMed database search was done for all English language articles on prostate artery embolization in prostate cancer, published between 2003 and 2019. For current review, information related to number, age of the patients, aetiology of the hematuria, bilateral or unilateral procedure, type of embolic material, technical and clinical success, complications, recurrent hematuria, hematocrit and hemoglobin levels were analyzed. Results A total of 10 original full-text comparative and non-comparative (case series) studies were reviewed. Minor complications described in the literature ranged from 10–50%. After prostate artery embolization, the recurrence of the haematuria occurred in 10–57% of the patients. Moreover, prostate artery embolization successfully treated lower urinary tract symptoms and urinary retention in prostate cancer patients. Conclusions The procedure appears safe, burdened with low risk of complications and accomplishes technical and clinical success. It is a promising option for patients with hemorrhage, but due to the scarcity of data further investigations are needed.
