To evaluate the benefits of repeat prostatic artery embolization (rePAE) for patients with persistent or recurrent symptoms after initial prostatic artery embolization (PAE).
This is a single-center retrospective study of all patients who underwent a rePAE between December 2014 and November 2020 for persistent or recurrent lower urinary tract symptoms. Symptoms were assessed before and after PAE and rePAE, using the International Prostate Symptom Score and quality of life (QoL) questionnaires. Patient characteristics, anatomical presentations, technical success rates, and complications of both procedures were collected. Clinical failure was defined as one of the following: less than 2 points' decrease in QoL, a QoL score higher than 3, acute urinary retention, and secondary surgery.
A total of 21 consecutive patients (mean age: 63.8 ± 8.1; [40-75] years) who underwent rePAE were included. The median follow-up after PAE was 27.7 [18.1-36.9]) months and 8.9 [3.4-10.8] months after rePAE. rePAE was performed at a mean of 19 ± 11.1 [6.9-49.6] months following PAE, and the overall clinical success rate was 33% (7/21). In patients undergoing rePAE because of persistent symptoms, the clinical success rate (18%) was non-significantly lower than that for patients treated for recurrent symptoms (50%) [OR 4.5 (95% CI 0.63-32 P = 0.13)]. The main anatomical revascularization pattern was recanalization of the native prostatic artery (29/45, 66%).
Patients who experience recurrent symptoms after PAE may benefit more from rePAE than those with persistent symptoms after PAE. Clinical success rates seem to be relatively low in both clinical scenarios.
