Insights

Prostatic artery embolization (PAE) effectively treats lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH) in the short and intermediate term, showing significant improvements in key health indicators.

Area of Science:

  • Urology
  • Interventional Radiology
  • Medical Devices

Background:

  • Benign prostatic hyperplasia (BPH) is a common condition causing lower urinary tract symptoms (LUTS).
  • Prostatic artery embolization (PAE) is an emerging minimally invasive treatment option for BPH.
  • Evidence on PAE outcomes and complications requires systematic summarization.

Purpose of the Study:

  • To systematically review and summarize current evidence on the efficacy and safety of PAE for treating LUTS secondary to BPH.
  • To assess the outcomes and complications associated with PAE in a large patient cohort.

Main Methods:

  • A comprehensive literature search was conducted across major databases (MEDLINE, Embase, Web of Science, Cochrane Library) up to August 2015.
  • Inclusion criteria involved peer-reviewed studies of PAE for BPH with >10 patients and measured parameters.
  • Two independent reviewers applied criteria, resolving disagreements by consensus.

Main Results:

  • Ten studies involving 788 patients with moderate to severe LUTS were included.
  • Significant improvements were observed in prostatic volume (PV), post-void residual (PVR), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life (QoL) at 6, 12, and 24 months post-procedure.
  • Prostate-specific antigen (PSA) showed no significant change at 6 months but improved at 12 and 24 months. International Index of Erectile Function (IIEF) remained unchanged at 6 and 12 months, with a significant reduction at 24 months.

Conclusions:

  • PAE demonstrates effectiveness in improving LUTS associated with BPH in the short and intermediate term.
  • The procedure leads to significant volumetric and symptomatic improvements in patients with BPH.
  • Further long-term data is needed to fully assess sustained efficacy and potential late complications.
