Prostatic arterial embolization (PAE) offers a minimally invasive treatment for benign prostatic hyperplasia. Detailed procedural knowledge ensures technical success and optimal clinical outcomes through bilateral embolization.

Area of Science:

  • Interventional Radiology
  • Urology

Background:

  • Benign prostatic hyperplasia (BPH) is a common condition in aging men.
  • Current treatments for BPH include medication and surgery.
  • Prostatic arterial embolization (PAE) is an emerging minimally invasive alternative.

Purpose of the Study:

  • To detail the procedural technique of PAE for benign prostatic hyperplasia.
  • To highlight key steps for achieving technical success and optimal clinical results.
  • To emphasize the importance of bilateral and complete prostatic embolization.

Main Methods:

  • Description of PAE procedural steps, including puncture site, catheter, and guidewire selection.
  • Techniques for identifying prostatic arteries using computed tomography angiography and digital subtraction angiography.

  • Guidance on superselective catheterization, contrast administration, particle selection, and endpoint determination.

    • Main Results:

    • PAE demonstrates promising preliminary results as an alternative to surgery.
    • Advantages include minimally invasive nature, outpatient setting, rapid recovery, and low morbidity.
    • Detailed technical knowledge is crucial for avoiding complications and achieving success.

    Conclusions:

    • PAE is a viable experimental treatment for BPH with significant advantages over traditional surgery.
    • Mastery of the detailed procedural technique is essential for effective and safe patient outcomes.
    • Bilateral and complete embolization are critical for achieving good clinical results.
