A comparison of 300-500micron vs 100-300 plus 300-500micron permanent microspheres in patients with long term urinary catheters treated with prostate artery embolization (PAE)

Submission Summary

Purpose :

Audit of clinical practice comparing the use of 100-300 plus 300-500micron (Group 1) vs 300-500micron permanent microspheres (Group 2) in achieving long-term urinary catheter independence following prostate artery embolization (PAE).

Materials & Methods :

Retrospective analysis of patients undergoing PAE with urinary catheters treated with either 100-300 plus 300-500micron (Group 1, n=18), or 300-500micron permanent microspheres (Group 2, n=18). Long-term catheter independence was evaluated.

Results :

36 patients were audited. There was no significant difference between age (median 78 (62-93)), prostate volume (mean=175ml), and time with catheter (mean=7.6months) between the two groups. Catheter independence at a median follow-up of 35 days (range 13 – 367 days) was 72.2% and 87.5% for Group 1 and 2 respectively (p>0.05). Complications for Group 1 were 2 simple urinary tract infections, and 1 case of spontaneously resolving penile pain. In Group 2, one patient had a femoral access site haematoma, treated conservatively.

Conclusions :

PAE is a safe and effective procedure for achieving long-term catheter independence. There was no significant difference in catheter removal when using either 100-300 plus 300-500micron (Group 1) or 300-500micron permanent microspheres (Group 2).
