KISILEVZKY, N. et al. Embolización prostática: un nuevo campo de actuación de la radiología intervencionista. Rev. argent. radiol. [online]. 2014, vol.78, n.2, pp.102-113. ISSN 1852-9992.

Purposes: To present the initial experience with prostatic embolization as an alternative treatment for benign prostatic hyperplasia (BPH) from a technical perspective to establish the contribution provided by diagnostic imaging. Materials and methods: Sixteen patients with lower urinary tract symptoms due to benign prostatic hyperplasia underwent prostatic embolization. All patients were evaluated with specific questionnaires to determine the severity of symptoms, impact on quality of life and erectile function, ultrasound and MRI of the pelvis, urinary flowmetry and PSA before and 30 days after the procedure. Results: Embolization was successful in all patients; in 10 cases the procedure was performed bilaterally and in six, only one side was embolized. The average time for completion of the procedure was 82 minutes and the average fluoroscopy time was 38.5 minutes. All procedures were performed on an outpatient basis with an average hospital stay of 6.4 hours. The mean contrast medium used was 175 ml. At 30 days there was a mean reduction on prostate volume of 21%. Clinical improvement was characterized by a mean 8-point improvement on IPSS, 2 points on QOL and 4 points on IIEF. The uroflowmetry improved 39% and PSA dropped 26%. No major complications that implied unscheduled hospitalization or performing additional surgical procedures were seen. Minor adverse events were verifi ed in 9 patients. Conclusion: The initial results of prostatic embolization as an alternative treatment for BPH indicate that it is a safe and effective procedure to be consolidated as a new field of action of interventional radiology.
