Abstract:
Eight patients with giant prostatic enlargement > 200 mL and lower urinary tract symptoms who underwent bilateral prostatic artery embolization (PAE) were reviewed. Mean prostate volume decreased from 318.2 mL to 212.2 mL (P < .01). At 5-month mean follow-up, International Prostate Symptom Score decreased by 16.7 points (P < .05), and urinary quality of life improved by 3.0 points (P < .01). Three of 4 catheter-dependent patients no longer needed catheterization after the procedure. No major complications were encountered. Preliminary results suggest PAE is safe and effective in patients with giant prostatic enlargement > 200 mL.
