Prostatic Artery Embolization in Patients with Refractory Lower Urinary Tract Symptoms after a Prior Minimally Invasive Surgical Treatment

Abstract

The purpose of this study was to report on prostatic artery embolization (PAE) outcomes in patients with refractory or recurrent lower urinary tract symptoms (LUTSs) due to benign prostatic hyperplasia (BPH) who had previously undergone a minimally invasive surgical technique (MIST). A single-center retrospective study identified 16 eligible patients. Baseline prostate volume at the time of PAE was 112.9 mL (SD ± 52.7). There were no adverse events throughout the follow-up period. There was significant improvement in International Prostate Symptom Score and quality of life from baseline of 23.5 (SD ± 5.1) and 4.9 (SD ± 0.9), respectively, to the last follow-up of 11.6 (SD ± 7.2) and 2 (SD ± 1.6), respectively. There was nonsignificant improvement in sexual function after PAE compared with baseline after MIST. PAE can be a safe and effective treatment in patients who have undergone prior MIST without negatively impacting erectile or ejaculatory function.
