Prostatic Artery Embolization (PAE) for Symptomatic Benign Prostatic Hyperplasia (BPH): Part 1, Pathological...

Area of Science:

• Urology
• Interventional Radiology
• Pathology

Background:

• Benign prostatic hyperplasia (BPH) pathology influences treatment response.
• BPH commonly affects the transition zone and periurethral regions.
• Histological heterogeneity of BPH nodules impacts treatment outcomes.

Purpose of the Study:

• To highlight the importance of pathological features in guiding prostatic artery embolization (PAE).
• To emphasize patient selection based on BPH characteristics for optimal PAE outcomes.
• To explore PAE's potential in managing the chronic progression of BPH.

Main Methods:

• Review of pathological findings in benign prostatic hyperplasia.
• Analysis of the anatomical origins of BPH relevant to PAE target areas.
• Correlation of BPH histological subtypes with PAE responsiveness.

Main Results:

• PAE targeting the transition zone and periurethral region is standard.
• Identifying responsive hyperplastic nodules (epithelial vs. stromal) has clinical implications.
• Lower urinary tract symptoms (LUTS) can stem from bladder changes secondary to obstruction.

Conclusions:

• Pathological awareness is crucial for interventional radiologists performing PAE.
• PAE can potentially relieve LUTS and delay BPH progression.
• Optimizing PAE strategies requires understanding BPH's pathological background.
